-### BREAKING CHANGES
-
-- CLI/RPC/Config
-  - [pubsub/events] \#6634 The `ResultEvent.Events` field is now of type `[]abci.Event` preserving event order instead of `map[string][]string`. (@alexanderbez)
-  - [config] \#5598 The `test_fuzz` and `test_fuzz_config` P2P settings have been removed. (@erikgrinaker)
-  - [config] \#5728 `fast_sync = "v1"` is no longer supported (@melekes)
-  - [cli] \#5772 `gen_node_key` prints JSON-encoded `NodeKey` rather than ID and does not save it to `node_key.json` (@melekes)
-  - [cli] \#5777 use hyphen-case instead of snake_case for all cli commands and config parameters (@cmwaters)
-  - [rpc] \#6019 standardise RPC errors and return the correct status code (@bipulprasad & @cmwaters)
-  - [rpc] \#6168 Change default sorting to desc for `/tx_search` results (@melekes)
-  - [cli] \#6282 User must specify the node mode when using `tendermint init` (@cmwaters)
-  - [state/indexer] \#6382 reconstruct indexer, move txindex into the indexer package (@JayT106)
-  - [cli] \#6372 Introduce `BootstrapPeers` as part of the new p2p stack. Peers to be connected on  startup (@cmwaters)
-  - [config] \#6462 Move `PrivValidator` configuration out of `BaseConfig` into its own section. (@tychoish)
-  - [rpc] \#6610 Add MaxPeerBlockHeight into /status rpc call (@JayT106)
-  - [libs/CList] \#6626 Automatically detach the prev/next elements in Remove function (@JayT106)
-
-- Apps
-  - [ABCI] \#6408 Change the `key` and `value` fields from `[]byte` to `string` in the `EventAttribute` type. (@alexanderbez)
-  - [ABCI] \#5447 Remove `SetOption` method from `ABCI.Client` interface
-  - [ABCI] \#5447 Reset `Oneof` indexes for  `Request` and `Response`.
-  - [ABCI] \#5818 Use protoio for msg length delimitation. Migrates from int64 to uint64 length delimiters.
-  - [Version] \#6494 `TMCoreSemVer` has been renamed to `TMVersion`.
-    - It is not required any longer to set ldflags to set version strings
-
-- P2P Protocol
-
-- Go API
-  - [pubsub] \#6634 The `Query#Matches` method along with other pubsub methods, now accepts a `[]abci.Event` instead of `map[string][]string`. (@alexanderbez)
-  - [p2p] \#6618 Move `p2p.NodeInfo` into `types` to support use of the SDK. (@tychoish)
-  - [p2p] \#6583 Make `p2p.NodeID` and `p2p.NetAddress` exported types to support their use in the RPC layer. (@tychoish)
-  - [node] \#6540 Reduce surface area of the `node` package by making most of the implementation details private. (@tychoish)
-  - [p2p] \#6547 Move the entire `p2p` package and all reactor implementations into `internal`.  (@tychoish)
-  - [libs/log] \#6534 Remove the existing custom Tendermint logger backed by go-kit. The logging interface, `Logger`, remains. Tendermint still provides a default logger backed by the performant zerolog logger. (@alexanderbez)
-  - [libs/time] \#6495 Move types/time to libs/time to improve consistency. (@tychoish)
-  - [mempool] \#6529 The `Context` field has been removed from the `TxInfo` type. `CheckTx` now requires a `Context` argument. (@alexanderbez)
-  - [abci/client, proxy] \#5673 `Async` funcs return an error, `Sync` and `Async` funcs accept `context.Context` (@melekes)
-  - [p2p] Remove unused function `MakePoWTarget`. (@erikgrinaker)
-  - [libs/bits] \#5720 Validate `BitArray` in `FromProto`, which now returns an error (@melekes)
-  - [proto/p2p] Rename `DefaultNodeInfo` and `DefaultNodeInfoOther` to `NodeInfo` and `NodeInfoOther` (@erikgrinaker)
-  - [proto/p2p] Rename `NodeInfo.default_node_id` to `node_id` (@erikgrinaker)
-  - [libs/os] Kill() and {Must,}{Read,Write}File() functions have been removed. (@alessio)
-  - [store] \#5848 Remove block store state in favor of using the db iterators directly (@cmwaters)
-  - [state] \#5864 Use an iterator when pruning state (@cmwaters)
-  - [types] \#6023 Remove `tm2pb.Header`, `tm2pb.BlockID`, `tm2pb.PartSetHeader` and `tm2pb.NewValidatorUpdate`.
-    - Each of the above types has a `ToProto` and `FromProto` method or function which replaced this logic.
-  - [light] \#6054 Move `MaxRetryAttempt` option from client to provider.
-    - `NewWithOptions` now sets the max retry attempts and timeouts (@cmwaters)
-  - [all] \#6077 Change spelling from British English to American (@cmwaters)
-    - Rename "Subscription.Cancelled()" to "Subscription.Canceled()" in libs/pubsub
-    - Rename "behaviour" pkg to "behavior" and internalized it in blockchain v2
-  - [rpc/client/http] \#6176 Remove `endpoint` arg from `New`, `NewWithTimeout` and `NewWithClient` (@melekes)
-  - [rpc/client/http] \#6176 Unexpose `WSEvents` (@melekes)
-  - [rpc/jsonrpc/client/ws_client] \#6176 `NewWS` no longer accepts options (use `NewWSWithOptions` and `OnReconnect` funcs to configure the client) (@melekes)
-  - [internal/libs] \#6366 Move `autofile`, `clist`,`fail`,`flowrate`, `protoio`, `sync`, `tempfile`, `test` and `timer` lib packages to an internal folder
-  - [libs/rand] \#6364 Remove most of libs/rand in favour of standard lib's `math/rand` (@liamsi)
-  - [mempool] \#6466 The original mempool reactor has been versioned as `v0` and moved to a sub-package under the root `mempool` package.
-    Some core types have been kept in the `mempool` package such as `TxCache` and it's implementations, the `Mempool` interface itself
-    and `TxInfo`. (@alexanderbez)
-  - [crypto/sr25519] \#6526 Do not re-execute the Ed25519-style key derivation step when doing signing and verification.  The derivation is now done once and only once.  This breaks `sr25519.GenPrivKeyFromSecret` output compatibility. (@Yawning)
-  - [types] \#6627 Move `NodeKey` to types to make the type public. 
-  - [config] \#6627 Extend `config` to contain methods `LoadNodeKeyID` and `LoadorGenNodeKeyID`
-
-- Blockchain Protocol
-
-- Data Storage
-  - [store/state/evidence/light] \#5771 Use an order-preserving varint key encoding (@cmwaters)
-  - [mempool] \#6396 Remove mempool's write ahead log (WAL), (previously unused by the tendermint code). (@tychoish)
-  - [state] \#6541 Move pruneBlocks from consensus/state to state/execution. (@JayT106)
-
-- Tooling
-  - [tools] \#6498 Set OS home dir to instead of the hardcoded PATH. (@JayT106)

-- [config] Add `--mode` flag and config variable. See [ADR-52](https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-052-tendermint-mode.md) @dongsam
-- [rpc] \#6329 Don't cap page size in unsafe mode (@gotjoshua, @cmwaters)
-- [pex] \#6305 v2 pex reactor with backwards compatability. Introduces two new pex messages to
-  accomodate for the new p2p stack. Removes the notion of seeds and crawling. All peer
-  exchange reactors behave the same. (@cmwaters)
-- [crypto] \#6376 Enable sr25519 as a validator key
-- [mempool] \#6466 Introduction of a prioritized mempool. (@alexanderbez)
-  - `Priority` and `Sender` have been introduced into the `ResponseCheckTx` type, where the `priority` will determine the prioritization of
-  the transaction when a proposer reaps transactions for a block proposal. The `sender` field acts as an index.
-  - Operators may toggle between the legacy mempool reactor, `v0`, and the new prioritized reactor, `v1`, by setting the
-  `mempool.version` configuration, where `v1` is the default configuration.
-  - Applications that do not specify a priority, i.e. zero, will have transactions reaped by the order in which they are received by the node.
-  - Transactions are gossiped in FIFO order as they are in `v0`.
-- [config/indexer] \#6411 Introduce support for custom event indexing data sources, specifically PostgreSQL. (@JayT106)
-
-### IMPROVEMENTS
-- [libs/log] Console log formatting changes as a result of \#6534 and \#6589. (@tychoish)
-- [statesync] \#6566 Allow state sync fetchers and request timeout to be configurable. (@alexanderbez)
-- [types] \#6478 Add `block_id` to `newblock` event (@jeebster)
-- [crypto/ed25519] \#5632 Adopt zip215 `ed25519` verification. (@marbar3778)
-- [crypto/ed25519] \#6526 Use [curve25519-voi](https://github.com/oasisprotocol/curve25519-voi) for `ed25519` signing and verification. (@Yawning)
-- [crypto/sr25519] \#6526 Use [curve25519-voi](https://github.com/oasisprotocol/curve25519-voi) for `sr25519` signing and verification. (@Yawning)
-- [privval] \#5603 Add `--key` to `init`, `gen_validator`, `testnet` & `unsafe_reset_priv_validator` for use in generating `secp256k1` keys.
-- [privval] \#5725 Add gRPC support to private validator.
-- [privval] \#5876 `tendermint show-validator` will query the remote signer if gRPC is being used (@marbar3778)
-- [abci/client] \#5673 `Async` requests return an error if queue is full (@melekes)
-- [mempool] \#5673 Cancel `CheckTx` requests if RPC client disconnects or times out (@melekes)
-- [abci] \#5706 Added `AbciVersion` to `RequestInfo` allowing applications to check ABCI version when connecting to Tendermint. (@marbar3778)
-- [blockchain/v1] \#5728 Remove in favor of v2 (@melekes)
-- [blockchain/v0] \#5741 Relax termination conditions and increase sync timeout (@melekes)
-- [cli] \#5772 `gen_node_key` output now contains node ID (`id` field) (@melekes)
-- [blockchain/v2] \#5774 Send status request when new peer joins (@melekes)
-- [consensus] \#5792 Deprecates the `time_iota_ms` consensus parameter, to reduce the bug surface. The parameter is no longer used. (@valardragon)
-- [store] \#5888 store.SaveBlock saves using batches instead of transactions for now to improve ACID properties. This is a quick fix for underlying issues around tm-db and ACID guarantees. (@githubsands)
-- [consensus] \#5987 Remove `time_iota_ms` from consensus params. Merge `tmproto.ConsensusParams` and `abci.ConsensusParams`. (@marbar3778)
-- [types] \#5994 Reduce the use of protobuf types in core logic. (@marbar3778)
-  - `ConsensusParams`, `BlockParams`, `ValidatorParams`, `EvidenceParams`, `VersionParams`, `sm.Version` and `version.Consensus` have become native types. They still utilize protobuf when being sent over the wire or written to disk.
-- [rpc/client/http] \#6163 Do not drop events even if the `out` channel is full (@melekes)
-- [node] \#6059 Validate and complete genesis doc before saving to state store (@silasdavis)
-- [state] \#6067 Batch save state data (@githubsands & @cmwaters)
-- [crypto] \#6120 Implement batch verification interface for ed25519 and sr25519. (@marbar3778)
-- [types] \#6120 use batch verification for verifying commits signatures.
-  - If the key type supports the batch verification API it will try to batch verify. If the verification fails we will single verify each signature.
-- [privval/file] \#6185 Return error on `LoadFilePV`, `LoadFilePVEmptyState`. Allows for better programmatic control of Tendermint.
-- [privval] \#6240 Add `context.Context` to privval interface.
-- [rpc] \#6265 set cache control in http-rpc response header (@JayT106)

-- [crypto/merkle] \#6513 Optimize HashAlternatives (@marbar3778)
-- [p2p/pex] \#6509 Improve addrBook.hash performance (@cuonglm)
-- [consensus/metrics] \#6549 Change block_size gauge to a histogram for better observability over time (@marbar3778)
-- [statesync] \#6587 Increase chunk priority and re-request chunks that don't arrive (@cmwaters)
-- [state/privval] \#6578 No GetPubKey retry beyond the proposal/voting window (@JayT106)
-- [rpc] \#6615 Add TotalGasUsed to block_results response (@crypto-facs)
-- [cmd/tendermint/commands] \#6623 replace `$HOME/.some/test/dir` with `t.TempDir` (@tanyabouman)

-### BUG FIXES
-
-- [privval] \#5638 Increase read/write timeout to 5s and calculate ping interval based on it (@JoeKash)

 # Contributing
 
-Thank you for your interest in contributing to Tendermint! Before
-contributing, it may be helpful to understand the goal of the project. The goal
-of Tendermint is to develop a BFT consensus engine robust enough to
-support permissionless value-carrying networks. While all contributions are
-welcome, contributors should bear this goal in mind in deciding if they should
-target the main Tendermint project or a potential fork. When targeting the
-main Tendermint project, the following process leads to the best chance of
-landing changes in master.
+Thank you for considering making contributions to Tendermint and related repositories! Start by taking a look at the [coding repo](https://github.com/tendermint/coding) for overall information on repository workflow and standards.
 
-All work on the code base should be motivated by a [Github
-Issue](https://github.com/tendermint/tendermint/issues).
-[Search](https://github.com/tendermint/tendermint/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
-is a good place start when looking for places to contribute. If you
-would like to work on an issue which already exists, please indicate so
-by leaving a comment.
+Please follow standard github best practices: fork the repo, branch from the tip of develop, make some commits, and submit a pull request to develop. See the [open issues](https://github.com/tendermint/tendermint/issues) for things we need help with!
 
-All new contributions should start with a [Github
-Issue](https://github.com/tendermint/tendermint/issues/new/choose). The
-issue helps capture the problem you're trying to solve and allows for
-early feedback. Once the issue is created the process can proceed in different
-directions depending on how well defined the problem and potential
-solution are. If the change is simple and well understood, maintainers
-will indicate their support with a heartfelt emoji.
-
-If the issue would benefit from thorough discussion, maintainers may
-request that you create a [Request For
-Comment](https://github.com/tendermint/spec/tree/master/rfc)
-in the Tendermint spec repo. Discussion
-at the RFC stage will build collective understanding of the dimensions
-of the problems and help structure conversations around trade-offs.
-
-When the problem is well understood but the solution leads to large structural
-changes to the code base, these changes should be proposed in the form of an
-[Architectural Decision Record (ADR)](./docs/architecture/). The ADR will help
-build consensus on an overall strategy to ensure the code base maintains
-coherence in the larger context. If you are not comfortable with writing an
-ADR, you can open a less-formal issue and the maintainers will help you turn it
-into an ADR.
-
-> How to pick a number for the ADR?
-
-Find the largest existing ADR number and bump it by 1.
-
-When the problem as well as proposed solution are well understood,
-changes should start with a [draft
-pull request](https://github.blog/2019-02-14-introducing-draft-pull-requests/)
-against master. The draft signals that work is underway. When the work
-is ready for feedback, hitting "Ready for Review" will signal to the
-maintainers to take a look.

-- Go to the original repo checked out locally (i.e. `$GOPATH/src/github.com/tendermint/tendermint`)
-- `git remote rename origin upstream`
-- `git remote add origin git@github.com:ebuchman/basecoin.git`

 ```
-
-## Changelog
-
-Every fix, improvement, feature, or breaking change should be made in a
-pull-request that includes an update to the `CHANGELOG_PENDING.md` file.
-
-Changelog entries should be formatted as follows:
-
-```md
-- [module] \#xxx Some description about the change (@contributor)
+vagrant up
+vagrant ssh
+make test
 ```
 
-Here, `module` is the part of the code that changed (typically a
-top-level Go package), `xxx` is the pull-request number, and `contributor`
-is the author/s of the change.
-
-It's also acceptable for `xxx` to refer to the relevant issue number, but pull-request
-numbers are preferred.
-Note this means pull-requests should be opened first so the changelog can then
-be updated with the pull-request's number.
-There is no need to include the full link, as this will be added
-automatically during release. But please include the backslash and pound, eg. `\#2313`.
-
-Changelog entries should be ordered alphabetically according to the
-`module`, and numerically according to the pull-request number.
-
-Changes with multiple classifications should be doubly included (eg. a bug fix
-that is also a breaking change should be recorded under both).
-
-Breaking changes are further subdivided according to the APIs/users they impact.
-Any change that effects multiple APIs/users should be recorded multiply - for
-instance, a change to the `Blockchain Protocol` that removes a field from the
-header should also be recorded under `CLI/RPC/Config` since the field will be
-removed from the header in RPC responses as well.
-
-## Branching Model and Release
-
-The main development branch is master.
-
-Every release is maintained in a release branch named `vX.Y.Z`.
-
-Pending minor releases have long-lived release candidate ("RC") branches. Minor release changes should be merged to these long-lived RC branches at the same time that the changes are merged to master.
-
-Note all pull requests should be squash merged except for merging to a release branch (named `vX.Y`). This keeps the commit history clean and makes it
-easy to reference the pull request where a change was introduced.
-
-### Development Procedure
-
-The latest state of development is on `master`, which must never fail `make test`. _Never_ force push `master`, unless fixing broken git history (which we rarely do anyways).
-
-To begin contributing, create a development branch either on `github.com/tendermint/tendermint`, or your fork (using `git remote add origin`).
-
-Make changes, and before submitting a pull request, update the `CHANGELOG_PENDING.md` to record your change. Also, run either `git rebase` or `git merge` on top of the latest `master`. (Since pull requests are squash-merged, either is fine!)
-
-Update the `UPGRADING.md` if the change you've made is breaking and the
-instructions should be in place for a user on how he/she can upgrade it's
-software (ABCI application, Tendermint-based blockchain, light client, wallet).
-
-Once you have submitted a pull request label the pull request with either `R:minor`, if the change should be included in the next minor release, or `R:major`, if the change is meant for a major release.
-
-Sometimes (often!) pull requests get out-of-date with master, as other people merge different pull requests to master. It is our convention that pull request authors are responsible for updating their branches with master. (This also means that you shouldn't update someone else's branch for them; even if it seems like you're doing them a favor, you may be interfering with their git flow in some way!)
-
-#### Merging Pull Requests
-
-It is also our convention that authors merge their own pull requests, when possible. External contributors may not have the necessary permissions to do this, in which case, a member of the core team will merge the pull request once it's been approved.
-
-Before merging a pull request:
-
-- Ensure pull branch is up-to-date with a recent `master` (GitHub won't let you merge without this!)
-- Run `make test` to ensure that all tests pass
-- [Squash](https://stackoverflow.com/questions/5189560/squash-my-last-x-commits-together-using-git) merge pull request
-
-#### Pull Requests for Minor Releases
-
-If your change should be included in a minor release, please also open a PR against the long-lived minor release candidate branch (e.g., `rc1/v0.33.5`) _immediately after your change has been merged to master_.
-
-You can do this by cherry-picking your commit off master:
-
-```sh
-$ git checkout rc1/v0.33.5
-$ git checkout -b {new branch name}
-$ git cherry-pick {commit SHA from master}
-# may need to fix conflicts, and then use git add and git cherry-pick --continue
-$ git push origin {new branch name}
-```
-
-After this, you can open a PR. Please note in the PR body if there were merge conflicts so that reviewers can be sure to take a thorough look.
-
-### Git Commit Style
-
-We follow the [Go style guide on commit messages](https://tip.golang.org/doc/contribute.html#commit_messages). Write concise commits that start with the package name and have a description that finishes the sentence "This change modifies Tendermint to...". For example,
-
-```sh
-cmd/debug: execute p.Signal only when p is not nil
-
-[potentially longer description in the body]
-
-Fixes #nnnn
-```
-
-Each PR should have one commit once it lands on `master`; this can be accomplished by using the "squash and merge" button on Github. Be sure to edit your commit message, though!
-
-### Release Procedure
-
-#### Major Release
-
-This major release process assumes that this release was preceded by release candidates.
-If there were no release candidates, and you'd like to cut a major release directly from master, see below.
-
-1. Start on the latest RC branch (`RCx/vX.X.0`).
-2. Run integration tests.
-3. Branch off of the RC branch (`git checkout -b release-prep`) and prepare the release:
-   - "Squash" changes from the changelog entries for the RCs into a single entry,
-      and add all changes included in `CHANGELOG_PENDING.md`.
-      (Squashing includes both combining all entries, as well as removing or simplifying
-      any intra-RC changes. It may also help to alphabetize the entries by package name.)
-   - Run `python ./scripts/linkify_changelog.py CHANGELOG.md` to add links for
-     all PRs
-   - Ensure that UPGRADING.md is up-to-date and includes notes on any breaking changes
-      or other upgrading flows.
-   - Bump TMVersionDefault version in  `version.go`
-   - Bump P2P and block protocol versions in  `version.go`, if necessary
-   - Bump ABCI protocol version in `version.go`, if necessary
-   - Add any release notes you would like to be added to the body of the release to `release_notes.md`.
-4. Open a PR with these changes against the RC branch (`RCx/vX.X.0`).
-5. Once these changes are on the RC branch, branch off of the RC branch again to create a release branch:
-   - `git checkout RCx/vX.X.0`
-   - `git checkout -b release/vX.X.0`
-6. Push a tag with prepared release details. This will trigger the actual release `vX.X.0`.
-   - `git tag -a vX.X.0 -m 'Release vX.X.0'`
-   - `git push origin vX.X.0`
-7. Make sure that `master` is updated with the latest `CHANGELOG.md`, `CHANGELOG_PENDING.md`, and `UPGRADING.md`.
-8. Create the long-lived minor release branch `RC0/vX.X.1` for the next point release on this
-   new major release series.
-
-##### Major Release (from `master`)
-
-1. Start on `master`
-2. Run integration tests (see `test_integrations` in Makefile)
-3. Prepare release in a pull request against `master` (to be squash merged):
-   - Copy `CHANGELOG_PENDING.md` to top of `CHANGELOG.md`; if this release
-      had release candidates, squash all the RC updates into one
-   - Run `python ./scripts/linkify_changelog.py CHANGELOG.md` to add links for
-     all issues
-   - Run `bash ./scripts/authors.sh` to get a list of authors since the latest
-     release, and add the github aliases of external contributors to the top of
-     the changelog. To lookup an alias from an email, try `bash ./scripts/authors.sh <email>`
-   - Reset the `CHANGELOG_PENDING.md`
-   - Bump TMVersionDefault version in  `version.go`
-   - Bump P2P and block protocol versions in  `version.go`, if necessary
-   - Bump ABCI protocol version in `version.go`, if necessary
-   - Make sure all significant breaking changes are covered in `UPGRADING.md`
-   - Add any release notes you would like to be added to the body of the release to `release_notes.md`.
-4. Push a tag with prepared release details (this will trigger the release `vX.X.0`)
-   - `git tag -a vX.X.x -m 'Release vX.X.x'`
-   - `git push origin vX.X.x`
-5. Update the `CHANGELOG.md` file on master with the releases changelog.
-6. Delete any RC branches and tags for this release (if applicable)
-
-#### Minor Release (Point Releases)
-
-Minor releases are done differently from major releases: They are built off of long-lived backport branches, rather than from master.
-Each release "line" (e.g. 0.34 or 0.33) has its own long-lived backport branch, and
-the backport branches have names like `v0.34.x` or `v0.33.x` (literally, `x`; it is not a placeholder in this case).
-
-As non-breaking changes land on `master`, they should also be backported (cherry-picked) to these backport branches.
-
-We use Mergify's [backport feature](https://mergify.io/features/backports) to automatically backport to the needed branch. Depending on which backport branch you need to backport to there will be labels for them. To notify the bot to backport a pull request, mark the pull request with the label `backport-to-<backport_branch>`. Once the original pull request is merged, the bot will try to cherry-pick the pull request to the backport branch. If the bot fails to backport, it will open a pull request. The author of the original pull request is responsible for solving the conflicts and merging the pull request.
-
-Minor releases don't have release candidates by default, although any tricky changes may merit a release candidate.
-
-To create a minor release:
-
-1. Checkout the long-lived backport branch: `git checkout vX.X.x`
-2. Run integration tests: `make test_integrations`
-3. Check out a new branch and prepare the release:
-   - Copy `CHANGELOG_PENDING.md` to top of `CHANGELOG.md`
-   - Run `python ./scripts/linkify_changelog.py CHANGELOG.md` to add links for all issues
-   - Run `bash ./scripts/authors.sh` to get a list of authors since the latest release, and add the GitHub aliases of external contributors to the top of the CHANGELOG. To lookup an alias from an email, try `bash ./scripts/authors.sh <email>`
-   - Reset the `CHANGELOG_PENDING.md`
-   - Bump the ABCI version number, if necessary.
-     (Note that ABCI follows semver, and that ABCI versions are the only versions
-     which can change during minor releases, and only field additions are valid minor changes.)
-   - Add any release notes you would like to be added to the body of the release to `release_notes.md`.
-4. Open a PR with these changes that will land them back on `vX.X.x`
-5. Once this change has landed on the backport branch, make sure to pull it locally, then push a tag.
-   - `git tag -a vX.X.x -m 'Release vX.X.x'`
-   - `git push origin vX.X.x`
-6. Create a pull request back to master with the CHANGELOG & version changes from the latest release.
-   - Remove all `R:minor` labels from the pull requests that were included in the release.
-   - Do not merge the backport branch into master.
-
-#### Release Candidates
-
-Before creating an official release, especially a major release, we may want to create a
-release candidate (RC) for our friends and partners to test out. We use git tags to
-create RCs, and we build them off of RC branches. RC branches typically have names formatted
-like `RCX/vX.X.X` (or, concretely, `RC0/v0.34.0`), while the tags themselves follow
-the "standard" release naming conventions, with `-rcX` at the end (`vX.X.X-rcX`).
-
-(Note that branches and tags _cannot_ have the same names, so it's important that these branches
-have distinct names from the tags/release names.)
-
-1. Start from the RC branch (e.g. `RC0/v0.34.0`).
-2. Create the new tag, specifying a name and a tag "message":
-   `git tag -a v0.34.0-rc0 -m "Release Candidate v0.34.0-rc0`
-3. Push the tag back up to origin:
-   `git push origin v0.34.0-rc4`
-   Now the tag should be available on the repo's releases page.
-4. Create a new release candidate branch for any possible updates to the RC:
-   `git checkout -b RC1/v0.34.0; git push origin RC1/v0.34.0`
-
 ## Testing
 
-### Unit tests
+All repos should be hooked up to [CircleCI](https://circleci.com/).
 
-Unit tests are located in `_test.go` files as directed by [the Go testing
-package](https://golang.org/pkg/testing/). If you're adding or removing a
-function, please check there's a `TestType_Method` test for it.
+If they have `.go` files in the root directory, they will be automatically
+tested by circle using `go test -v -race ./...`. If not, they will need a
+`circle.yml`. Ideally, every repo has a `Makefile` that defines `make test` and
+includes its continuous integration status using a badge in the `README.md`.
 
-Run: `make test`
+## Branching Model and Release
 
-### Integration tests
+User-facing repos should adhere to the branching model: http://nvie.com/posts/a-successful-git-branching-model/.
+That is, these repos should be well versioned, and any merge to master requires a version bump and tagged release.
 
-Integration tests are also located in `_test.go` files. What differentiates
-them is a more complicated setup, which usually involves setting up two or more
-components.
+Libraries need not follow the model strictly, but would be wise to,
+especially `go-p2p` and `go-rpc`, as their versions are referenced in tendermint core.
 
-Run: `make test_integrations`
+### Development Procedure:
+- the latest state of development is on `develop`
+- `develop` must never fail `make test`
+- no --force onto `develop` (except when reverting a broken commit, which should seldom happen)
+- create a development branch either on github.com/tendermint/tendermint, or your fork (using `git add origin`)
+- before submitting a pull request, begin `git rebase` on top of `develop`
 
-### End-to-end tests
+### Pull Merge Procedure:
+- ensure pull branch is rebased on develop
+- run `make test` to ensure that all tests pass
+- merge pull request
+- the `unstable` branch may be used to aggregate pull merges before testing once
+- push master may request that pull requests be rebased on top of `unstable`
 
-End-to-end tests are used to verify a fully integrated Tendermint network.
+### Release Procedure:
+- start on `develop`
+- run integration tests (see `test_integrations` in Makefile)
+- prepare changelog/release issue
+- bump versions
+- push to release-vX.X.X to run the extended integration tests on the CI
+- merge to master
+- merge master back to develop
 
-See [README](./test/e2e/README.md) for details.
-
-Run:
-
-```sh
-cd test/e2e && \
-  make && \
-  ./build/runner -f networks/ci.toml
-```
-
-### Model-based tests (ADVANCED)
-
-*NOTE: if you're just submitting your first PR, you won't need to touch these
-most probably (99.9%)*.
-
-For components, that have been [formally
-verified](https://en.wikipedia.org/wiki/Formal_verification) using
-[TLA+](https://en.wikipedia.org/wiki/TLA%2B), it may be possible to generate
-tests using a combination of the [Apalache Model
-Checker](https://apalache.informal.systems/) and [tendermint-rs testgen
-util](https://github.com/informalsystems/tendermint-rs/tree/master/testgen).
-
-Now, I know there's a lot to take in. If you want to learn more, check out [
-this video](https://www.youtube.com/watch?v=aveoIMphzW8) by Andrey Kupriyanov
-& Igor Konnov.
-
-At the moment, we have model-based tests for the light client, located in the
-`./light/mbt` directory.
-
-Run: `cd light/mbt && go test`
-
-### Fuzz tests (ADVANCED)
-
-*NOTE: if you're just submitting your first PR, you won't need to touch these
-most probably (99.9%)*.
-
-[Fuzz tests](https://en.wikipedia.org/wiki/Fuzzing) can be found inside the
-`./test/fuzz` directory. See [README.md](./test/fuzz/README.md) for details.
-
-Run: `cd test/fuzz && make fuzz-{PACKAGE-COMPONENT}`
-
-### Jepsen tests (ADVANCED)
-
-*NOTE: if you're just submitting your first PR, you won't need to touch these
-most probably (99.9%)*.
-
-[Jepsen](http://jepsen.io/) tests are used to verify the
-[linearizability](https://jepsen.io/consistency/models/linearizable) property
-of the Tendermint consensus. They are located in a separate repository
--> <https://github.com/tendermint/jepsen>. Please refer to its README for more
-information.
-
-### RPC Testing
-
-**If you contribute to the RPC endpoints it's important to document your
-changes in the [Openapi file](./rpc/openapi/openapi.yaml)**.
-
-To test your changes you must install `nodejs` and run:
-
-```bash
-npm i -g dredd
-make build-linux build-contract-tests-hooks
-make contract-tests
-```
-
-**WARNING: these are currently broken due to <https://github.com/apiaryio/dredd>
-not supporting complete OpenAPI 3**.
-
-This command will popup a network and check every endpoint against what has
-been documented.
+### Hotfix Procedure:
+- start on `master`
+- checkout a new branch named hotfix-vX.X.X
+- make the required changes
+  - these changes should be small and an absolute necessity
+  - add a note to CHANGELOG.md
+- bumb versions
+- push to hotfix-vX.X.X to run the extended integration tests on the CI
+- merge hotfix-vX.X.X to master
+- merge hotfix-vX.X.X to develop
+- delete the hotfix-vX.X.X branch

-## Contributing
-
-Please abide by the [Code of Conduct](CODE_OF_CONDUCT.md) in all interactions.
-
-Before contributing to the project, please take a look at the [contributing guidelines](CONTRIBUTING.md)
-and the [style guide](STYLE_GUIDE.md). You may also find it helpful to read the
-[specifications](https://github.com/tendermint/spec), watch the [Developer Sessions](/docs/DEV_SESSIONS.md), 
-and familiarize yourself with our
-[Architectural Decision Records](https://github.com/tendermint/tendermint/tree/master/docs/architecture).
-
-## Versioning
-
-### Semantic Versioning
-
-Tendermint uses [Semantic Versioning](http://semver.org/) to determine when and how the version changes.
-According to SemVer, anything in the public API can change at any time before version 1.0.0
-
-To provide some stability to Tendermint users in these 0.X.X days, the MINOR version is used
-to signal breaking changes across a subset of the total public API. This subset includes all
-interfaces exposed to other processes (cli, rpc, p2p, etc.), but does not
-include the Go APIs.
-
-That said, breaking changes in the following packages will be documented in the
-CHANGELOG even if they don't lead to MINOR version bumps:
-
-- crypto
-- config
-- libs
-    - bits
-    - bytes
-    - json
-    - log
-    - math
-    - net
-    - os
-    - protoio
-    - rand
-    - sync
-    - strings
-    - service
-- node
-- rpc/client
-- types
-
-### Upgrades
-
-In an effort to avoid accumulating technical debt prior to 1.0.0,
-we do not guarantee that breaking changes (ie. bumps in the MINOR version)
-will work with existing Tendermint blockchains. In these cases you will
-have to start a new blockchain, or write something custom to get the old
-data into the new chain. However, any bump in the PATCH version should be 
-compatible with existing blockchain histories.
-
-
-For more information on upgrading, see [UPGRADING.md](./UPGRADING.md).
-
-### Supported Versions
-
-Because we are a small core team, we only ship patch updates, including security updates,
-to the most recent minor release and the second-most recent minor release. Consequently,
-we strongly recommend keeping Tendermint up-to-date. Upgrading instructions can be found
-in [UPGRADING.md](./UPGRADING.md).
+For more details (or if it fails), [read the docs](https://tendermint.readthedocs.io/en/master/install.html).

+
+Exported objects in these packages that are not covered by the versioning scheme

-## Reporting a Bug
-
-As part of our [Coordinated Vulnerability Disclosure
-Policy](https://tendermint.com/security), we operate a [bug
-bounty](https://hackerone.com/tendermint).
-See the policy for more details on submissions and rewards, and see "Example Vulnerabilities" (below) for examples of the kinds of bugs we're most interested in.
-
-### Guidelines
-
-We require that all researchers:
-
-* Use the bug bounty to disclose all vulnerabilities, and avoid posting vulnerability information in public places, including Github Issues, Discord channels, and Telegram groups
-* Make every effort to avoid privacy violations, degradation of user experience, disruption to production systems (including but not limited to the Cosmos Hub), and destruction of data
-* Keep any information about vulnerabilities that you’ve discovered confidential between yourself and the Tendermint Core engineering team until the issue has been resolved and disclosed
-* Avoid posting personally identifiable information, privately or publicly
-
-If you follow these guidelines when reporting an issue to us, we commit to:
-
-* Not pursue or support any legal action related to your research on this vulnerability
-* Work with you to understand, resolve and ultimately disclose the issue in a timely fashion
-
-## Disclosure Process
-
-Tendermint Core uses the following disclosure process:
-
-1. Once a security report is received, the Tendermint Core team works to verify the issue and confirm its severity level using CVSS.
-2. The Tendermint Core team collaborates with the Gaia team to determine the vulnerability’s potential impact on the Cosmos Hub.
-3. Patches are prepared for eligible releases of Tendermint in private repositories. See “Supported Releases” below for more information on which releases are considered eligible.
-4. If it is determined that a CVE-ID is required, we request a CVE through a CVE Numbering Authority.
-5. We notify the community that a security release is coming, to give users time to prepare their systems for the update. Notifications can include forum posts, tweets, and emails to partners and validators, including emails sent to the [Tendermint Security Mailing List](https://berlin.us4.list-manage.com/subscribe?u=431b35421ff7edcc77df5df10&id=3fe93307bc).
-6. 24 hours following this notification, the fixes are applied publicly and new releases are issued.
-7. Cosmos SDK and Gaia update their Tendermint Core dependencies to use these releases, and then themselves issue new releases.
-8. Once releases are available for Tendermint Core, Cosmos SDK and Gaia, we notify the community, again, through the same channels as above. We also publish a Security Advisory on Github and publish the CVE, as long as neither the Security Advisory nor the CVE include any information on how to exploit these vulnerabilities beyond what information is already available in the patch itself.
-9. Once the community is notified, we will pay out any relevant bug bounties to submitters.
-10. One week after the releases go out, we will publish a post with further details on the vulnerability as well as our response to it.
-
-This process can take some time. Every effort will be made to handle the bug in as timely a manner as possible, however it's important that we follow the process described above to ensure that disclosures are handled consistently and to keep Tendermint Core and its downstream dependent projects--including but not limited to Gaia and the Cosmos Hub--as secure as possible.
-

-## Supported Releases
-
-The Tendermint Core team commits to releasing security patch releases for both the latest minor release as well for the major/minor release that the Cosmos Hub is running.
-
-If you are running older versions of Tendermint Core, we encourage you to upgrade at your earliest opportunity so that you can receive security patches directly from the Tendermint repo. While you are welcome to backport security patches to older versions for your own use, we will not publish or promote these backports.
-
-## Scope
-

-# Go Coding Style Guide
-
-In order to keep our code looking good with lots of programmers working on it, it helps to have a "style guide", so all
-the code generally looks quite similar. This doesn't mean there is only one "right way" to write code, or even that this
-standard is better than your style.  But if we agree to a number of stylistic practices, it makes it much easier to read
-and modify new code. Please feel free to make suggestions if there's something you would like to add or modify.
-
-We expect all contributors to be familiar with [Effective Go](https://golang.org/doc/effective_go.html)
-(and it's recommended reading for all Go programmers anyways). Additionally, we generally agree with the suggestions
- in [Uber's style guide](https://github.com/uber-go/guide/blob/master/style.md) and use that as a starting point.
-
-
-## Code Structure
-
-Perhaps more key for code readability than good commenting is having the right structure. As a rule of thumb, try to write
-in a logical order of importance, taking a little time to think how to order and divide the code such that someone could
-scroll down and understand the functionality of it just as well as you do. A loose example of such order would be:
-
-* Constants, global and package-level variables
-* Main Struct
-* Options (only if they are seen as critical to the struct else they should be placed in another file)
-* Initialization / Start and stop of the service
-* Msgs/Events
-* Public Functions (In order of most important)
-* Private/helper functions
-* Auxiliary structs and function (can also be above private functions or in a separate file)
-
-## General
-
-* Use `gofmt` (or `goimport`) to format all code upon saving it.  (If you use VIM, check out vim-go).
-* Use a linter (see below) and generally try to keep the linter happy (where it makes sense).
-* Think about documentation, and try to leave godoc comments, when it will help new developers.
-* Every package should have a high level doc.go file to describe the purpose of that package, its main functions, and any other relevant information.
-* `TODO` should not be used. If important enough should be recorded as an issue.
-* `BUG` / `FIXME` should be used sparingly to guide future developers on some of the vulnerabilities of the code.
-* `XXX` can be used in work-in-progress (prefixed with "WIP:" on github) branches but they must be removed before approving a PR.
-* Applications (e.g. clis/servers) *should* panic on unexpected unrecoverable errors and print a stack trace.
-
-## Comments
-
-* Use a space after comment deliminter (ex. `// your comment`).
-* Many comments are not sentences. These should begin with a lower case letter and end without a period.
-* Conversely, sentences in comments should be sentenced-cased and end with a period.
-
-## Linters
-
-These must be applied to all (Go) repos.
-
-* [shellcheck](https://github.com/koalaman/shellcheck)
-* [golangci-lint](https://github.com/golangci/golangci-lint) (covers all important linters)
-    * See the `.golangci.yml` file in each repo for linter configuration.
-
-## Various
-
-* Reserve "Save" and "Load" for long-running persistence operations. When parsing bytes, use "Encode" or "Decode".
-* Maintain consistency across the codebase.
-* Functions that return functions should have the suffix `Fn`
-* Names should not [stutter](https://blog.golang.org/package-names). For example, a struct generally shouldn’t have
-  a field named after itself; e.g., this shouldn't occur:
-
-``` golang
-type middleware struct {
-	middleware Middleware
-}
-```
-
-* In comments, use "iff" to mean, "if and only if".
-* Product names are capitalized, like "Tendermint", "Basecoin", "Protobuf", etc except in command lines: `tendermint --help`
-* Acronyms are all capitalized, like "RPC", "gRPC", "API".  "MyID", rather than "MyId".
-* Prefer errors.New() instead of fmt.Errorf() unless you're actually using the format feature with arguments.
-
-## Importing Libraries
-
-Sometimes it's necessary to rename libraries to avoid naming collisions or ambiguity.
-
-* Use [goimports](https://godoc.org/golang.org/x/tools/cmd/goimports)
-* Separate imports into blocks - one for the standard lib, one for external libs and one for application libs.
-* Here are some common library labels for consistency:
-    * dbm "github.com/tendermint/tm-db"
-    * tmcmd "github.com/tendermint/tendermint/cmd/tendermint/commands"
-    * tmcfg "github.com/tendermint/tendermint/config/tendermint"
-    * tmtypes "github.com/tendermint/tendermint/types"
-* Never use anonymous imports (the `.`), for example, `tmlibs/common` or anything else.
-* When importing a pkg from the `tendermint/libs` directory, prefix the pkg alias with tm.
-    * tmbits "github.com/tendermint/tendermint/libs/bits"
-* tip: Use the `_` library import to import a library for initialization effects (side effects)
-
-## Dependencies
-
-* Dependencies should be pinned by a release tag, or specific commit, to avoid breaking `go get` when external dependencies are updated.
-* Refer to the [contributing](CONTRIBUTING.md) document for more details
-
-## Testing
-
-* The first rule of testing is: we add tests to our code
-* The second rule of testing is: we add tests to our code
-* For Golang testing:
-    * Make use of table driven testing where possible and not-cumbersome
-        * [Inspiration](https://dave.cheney.net/2013/06/09/writing-table-driven-tests-in-go)
-    * Make use of [assert](https://godoc.org/github.com/stretchr/testify/assert) and [require](https://godoc.org/github.com/stretchr/testify/require)
-* When using mocks, it is recommended to use Testify [mock] (<https://pkg.go.dev/github.com/stretchr/testify/mock>
- ) along with [Mockery](https://github.com/vektra/mockery) for autogeneration
-
-## Errors
-
-* Ensure that errors are concise, clear and traceable.
-* Use stdlib errors package.
-* For wrapping errors, use `fmt.Errorf()` with `%w`.
-* Panic is appropriate when an internal invariant of a system is broken, while all other cases (in particular,
-  incorrect or invalid usage) should return errors.
-
-## Config
-
-* Currently the TOML filetype is being used for config files
-* A good practice is to store per-user config files under `~/.[yourAppName]/config.toml`
-
-## CLI
-
-* When implementing a CLI use [Cobra](https://github.com/spf13/cobra) and [Viper](https://github.com/spf13/viper).
-* Helper messages for commands and flags must be all lowercase.
-* Instead of using pointer flags (eg. `FlagSet().StringVar`) use Viper to retrieve flag values (eg. `viper.GetString`)
-    * The flag key used when setting and getting the flag should always be stored in a
-   variable taking the form `FlagXxx` or `flagXxx`.
-    * Flag short variable descriptions should always start with a lower case character as to remain consistent with
-   the description provided in the default `--help` flag.
-
-## Version
-
-* Every repo should have a version/version.go file that mimics the Tendermint Core repo
-* We read the value of the constant version in our build scripts and hence it has to be a string
-
-## Non-Go Code
-
-* All non-Go code (`*.proto`, `Makefile`, `*.sh`), where there is no common
-   agreement on style, should be formatted according to
-   [EditorConfig](http://editorconfig.org/) config:
-
-   ```toml
-   # top-most EditorConfig file
-   root = true
-
-   # Unix-style newlines with a newline ending every file
-   [*]
-   charset = utf-8
-   end_of_line = lf
-   insert_final_newline = true
-   trim_trailing_whitespace = true
-
-   [Makefile]
-   indent_style = tab
-
-   [*.sh]
-   indent_style = tab
-
-   [*.proto]
-   indent_style = space
-   indent_size = 2
-   ```
-
-   Make sure the file above (`.editorconfig`) are in the root directory of your
-   repo and you have a [plugin for your
-   editor](http://editorconfig.org/#download) installed.

-# Upgrading Tendermint Core
-
-This guide provides instructions for upgrading to specific versions of Tendermint Core.
-
-## Unreleased
-
-### ABCI Changes
-
-* Added `AbciVersion` to `RequestInfo`. Applications should check that the ABCI version they expect is being used in order to avoid unimplemented changes errors.
-* The method `SetOption` has been removed from the ABCI.Client interface. This feature was used in the early ABCI implementation's.
-* Messages are written to a byte stream using uin64 length delimiters instead of int64.
-* When mempool `v1` is enabled, transactions broadcasted via `sync` mode may return a successful
-  response with a transaction hash indicating that the transaction was successfully inserted into
-  the mempool. While this is true for `v0`, the `v1` mempool reactor may at a later point in time
-  evict or even drop this transaction after a hash has been returned. Thus, the user or client must
-  query for that transaction to check if it is still in the mempool.
-
-### Config Changes
-
-* `fast_sync = "v1"` is no longer supported. Please use `v2` instead.
-
-* All config parameters are now hyphen-case (also known as kebab-case) instead of snake_case. Before restarting the node make sure
-  you have updated all the variables in your `config.toml` file.
-
-* Added `--mode` flag and `mode` config variable on `config.toml` for setting Mode of the Node: `full` | `validator` | `seed` (default: `full`)
-  [ADR-52](https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-052-tendermint-mode.md)
-  
-* `BootstrapPeers` has been added as part of the new p2p stack. This will eventually replace
-  `Seeds`. Bootstrap peers are connected with on startup if needed for peer discovery. Unlike
-  persistent peers, there's no gaurantee that the node will remain connected with these peers. 
-
-- configuration values starting with `priv-validator-` have moved to the new
-  `priv-validator` section, without the `priv-validator-` prefix.
-
-### CLI Changes
-
-* You must now specify the node mode (validator|full|seed) in `tendermint init [mode]`
-
-* If you had previously used `tendermint gen_node_key` to generate a new node
-  key, keep in mind that it no longer saves the output to a file. You can use
-  `tendermint init validator` or pipe the output of `tendermint gen_node_key` to
-  `$TMHOME/config/node_key.json`:
-
-  ```
-  $ tendermint gen_node_key > $TMHOME/config/node_key.json
-  ```
-
-* CLI commands and flags are all now hyphen-case instead of snake_case.
-  Make sure to adjust any scripts that calls a cli command with snake_casing
-
-### API Changes
-
-The p2p layer was reimplemented as part of the 0.35 release cycle, and
-all reactors were refactored. As part of that work these
-implementations moved into the `internal` package and are no longer
-considered part of the public Go API of tendermint. These packages
-are:
-
-- `p2p`
-- `mempool`
-- `consensus`
-- `statesync`
-- `blockchain`
-- `evidence`
-
-Accordingly, the space `node` package was changed to reduce access to
-tendermint internals: applications that use tendermint as a library
-will need to change to accommodate these changes. Most notably:
-
-- The `Node` type has become internal, and all constructors return a
-  `service.Service` implementation.
-
-- The `node.DefaultNewNode` and `node.NewNode` constructors are no
-  longer exported and have been replaced with `node.New` and
-  `node.NewDefault` which provide more functional interfaces.
-
-## v0.34.0
-
-**Upgrading to Tendermint 0.34 requires a blockchain restart.**
-This release is not compatible with previous blockchains due to changes to
-the encoding format (see "Protocol Buffers," below) and the block header (see "Blockchain Protocol").
-
-Note also that Tendermint 0.34 also requires Go 1.16 or higher.
-
-### ABCI Changes
-
-* The `ABCIVersion` is now `0.17.0`.
-
-* New ABCI methods (`ListSnapshots`, `LoadSnapshotChunk`, `OfferSnapshot`, and `ApplySnapshotChunk`)
-  were added to support the new State Sync feature.
-  Previously, syncing a new node to a preexisting network could take days; but with State Sync,
-  new nodes are able to join a network in a matter of seconds.
-  Read [the spec](https://docs.tendermint.com/master/spec/abci/apps.html#state-sync)
-  if you want to learn more about State Sync, or if you'd like your application to use it.
-  (If you don't want to support State Sync in your application, you can just implement these new
-  ABCI methods as no-ops, leaving them empty.)
-
-* `KV.Pair` has been replaced with `abci.EventAttribute`. The `EventAttribute.Index` field
-  allows ABCI applications to dictate which events should be indexed.
-
-* The blockchain can now start from an arbitrary initial height,
-  provided to the application via `RequestInitChain.InitialHeight`.
-
-* ABCI evidence type is now an enum with two recognized types of evidence:
-  `DUPLICATE_VOTE` and `LIGHT_CLIENT_ATTACK`.
-  Applications should be able to handle these evidence types
-  (i.e., through slashing or other accountability measures).
-
-* The [`PublicKey` type](https://github.com/tendermint/tendermint/blob/master/proto/tendermint/crypto/keys.proto#L13-L15)
-  (used in ABCI as part of `ValidatorUpdate`) now uses a `oneof` protobuf type.
-  Note that since Tendermint only supports ed25519 validator keys, there's only one
-  option in the `oneof`.  For more, see "Protocol Buffers," below.
-
-* The field `Proof`, on the ABCI type `ResponseQuery`, is now named `ProofOps`.
-  For more, see "Crypto," below.
-
-* The method `SetOption` has been removed from the ABCI.Client interface. This feature was used in the early ABCI implementation's.
-
-### P2P Protocol
-
-The default codec is now proto3, not amino. The schema files can be found in the `/proto`
-directory. For more, see "Protobuf," below.
-
-### Blockchain Protocol
-
-* `Header#LastResultsHash`, which is the root hash of a Merkle tree built from
-`ResponseDeliverTx(Code, Data)` as of v0.34 also includes `GasWanted` and `GasUsed`
-fields.
-
-* Merkle hashes of empty trees previously returned nothing, but now return the hash of an empty input,
-  to conform with [RFC-6962](https://tools.ietf.org/html/rfc6962).
-  This mainly affects `Header#DataHash`, `Header#LastResultsHash`, and
-  `Header#EvidenceHash`, which are often empty. Non-empty hashes can also be affected, e.g. if their
-  inputs depend on other (empty) Merkle hashes, giving different results.
-
-### Transaction Indexing
-
-Tendermint now relies on the application to tell it which transactions to index. This means that
-in the `config.toml`, generated by Tendermint, there is no longer a way to specify which
-transactions to index. `tx.height` and `tx.hash` will always be indexed when using the `kv` indexer.
-
-Applications must now choose to either a) enable indexing for all transactions, or
-b) allow node operators to decide which transactions to index.
-Applications can notify Tendermint to index a specific transaction by setting
-`Index: bool` to `true` in the Event Attribute:
-
-```go
-[]types.Event{
-	{
-		Type: "app",
-		Attributes: []types.EventAttribute{
-			{Key: []byte("creator"), Value: []byte("Cosmoshi Netowoko"), Index: true},
-		},
-	},
-}
-```
-
-### Protocol Buffers
-
-Tendermint 0.34 replaces Amino with Protocol Buffers for encoding.
-This migration is extensive and results in a number of changes, however,
-Tendermint only uses the types generated from Protocol Buffers for disk and
-wire serialization.
-**This means that these changes should not affect you as a Tendermint user.**
-
-However, Tendermint users and contributors may note the following changes:
-
-* Directory layout changes: All proto files have been moved under one directory, `/proto`.
-  This is in line with the recommended file layout by [Buf](https://buf.build).
-  For more, see the [Buf documentation](https://buf.build/docs/lint-checkers#file_layout).
-* ABCI Changes: As noted in the "ABCI Changes" section above, the `PublicKey` type now uses
-  a `oneof` type.
-
-For more on the Protobuf changes, please see our [blog post on this migration](https://medium.com/tendermint/tendermint-0-34-protocol-buffers-and-you-8c40558939ae).
-
-### Consensus Parameters
-
-Tendermint 0.34 includes new and updated consensus parameters.
-
-#### Version Parameters (New)
-
-* `AppVersion`, which is the version of the ABCI application.
-
-#### Evidence Parameters
-
-* `MaxBytes`, which caps the total amount of evidence. The default is 1048576 (1 MB).
-
-### Crypto
-
-#### Keys
-
-* Keys no longer include a type prefix. For example, ed25519 pubkeys have been renamed from
-  `PubKeyEd25519` to `PubKey`. This reduces stutter (e.g., `ed25519.PubKey`).
-* Keys are now byte slices (`[]byte`) instead of byte arrays (`[<size>]byte`).
-* The multisig functionality that was previously in Tendermint now has
-  a new home within the Cosmos SDK:
-  [`cosmos/cosmos-sdk/types/multisig`](https://github.com/cosmos/cosmos-sdk/blob/master/crypto/types/multisig/multisignature.go).
-
-#### `merkle` Package
-
-* `SimpleHashFromMap()` and `SimpleProofsFromMap()` were removed.
-* The prefix `Simple` has been removed. (For example, `SimpleProof` is now called `Proof`.)
-* All protobuf messages have been moved to the `/proto` directory.
-* The protobuf message `Proof` that contained multiple ProofOp's has been renamed to `ProofOps`.
-  As noted above, this affects the ABCI type `ResponseQuery`:
-  The field that was named Proof is now named `ProofOps`.
-* `HashFromByteSlices` and `ProofsFromByteSlices` now return a hash for empty inputs, to conform with
-  [RFC-6962](https://tools.ietf.org/html/rfc6962).
-
-### `libs` Package
-
-The `bech32` package has moved to the Cosmos SDK:
-[`cosmos/cosmos-sdk/types/bech32`](https://github.com/cosmos/cosmos-sdk/tree/4173ea5ebad906dd9b45325bed69b9c655504867/types/bech32).
-
-### CLI
-
-The `tendermint lite` command has been renamed to `tendermint light` and has a slightly different API.
-See [the docs](https://docs.tendermint.com/master/tendermint-core/light-client-protocol.html#http-proxy) for details.
-
-### Light Client
-
-We have a new, rewritten light client! You can
-[read more](https://medium.com/tendermint/everything-you-need-to-know-about-the-tendermint-light-client-f80d03856f98)
-about the justifications and details behind this change.
-
-Other user-relevant changes include:
-
-* The old `lite` package was removed; the new light client uses the `light` package.
-* The `Verifier` was broken up into two pieces:
-    * Core verification logic (pure `VerifyX` functions)
-    * `Client` object, which represents the complete light client
-* The new light clients stores headers & validator sets as `LightBlock`s
-* The RPC client can be found in the `/rpc` directory.
-* The HTTP(S) proxy is located in the `/proxy` directory.
-
-### `state` Package
-
-* A new field `State.InitialHeight` has been added to record the initial chain height, which must be `1`
-  (not `0`) if starting from height `1`. This can be configured via the genesis field `initial_height`.
-* The `state` package now has a `Store` interface. All functions in
-  [state/store.go](https://github.com/tendermint/tendermint/blob/56911ee35298191c95ef1c7d3d5ec508237aaff4/state/store.go#L42-L42)
-  are now part of the interface. The interface returns errors on all methods and can be used by calling `state.NewStore(dbm.DB)`.
-
-### `privval` Package
-
-All requests are now accompanied by the chain ID from the network.
-This is a optional field and can be ignored by key management systems;
-however, if you are using the same key management system for multiple different
-blockchains, we recommend that you check the chain ID.
-
-
-### RPC
-
-* `/unsafe_start_cpu_profiler`, `/unsafe_stop_cpu_profiler` and
-  `/unsafe_write_heap_profile` were removed.
-   For profiling, please use the pprof server, which can
-  be enabled through `--rpc.pprof_laddr=X` flag or `pprof_laddr=X` config setting
-  in the rpc section.
-* The `Content-Type` header returned on RPC calls is now (correctly) set as `application/json`.
-
-### Version
-
-Version is now set through Go linker flags `ld_flags`. Applications that are using tendermint as a library should set this at compile time.
-
-Example:
-
-```sh
-go install -mod=readonly -ldflags "-X github.com/tendermint/tendermint/version.TMCoreSemVer=$(go list -m github.com/tendermint/tendermint | sed  's/ /\@/g') -s -w " -trimpath ./cmd
-```
-
-Additionally, the exported constant `version.Version` is now `version.TMCoreSemVer`.
-
-## v0.33.4
-
-### Go API
-
-* `rpc/client` HTTP and local clients have been moved into `http` and `local`
-  subpackages, and their constructors have been renamed to `New()`.
-
-### Protobuf Changes
-
-When upgrading to version 0.33.4 you will have to fetch the `third_party`
-directory along with the updated proto files.
-
-### Block Retention
-
-ResponseCommit added a field for block retention. The application can provide information to Tendermint on how to prune blocks.
-If an application would like to not prune any blocks pass a `0` in this field.
-
-```proto
-message ResponseCommit {
-  // reserve 1
-  bytes  data          = 2; // the Merkle root hash
-  ++ uint64 retain_height = 3; // the oldest block height to retain ++
-}
-```
-
-## v0.33.0
-
-This release is not compatible with previous blockchains due to commit becoming
-signatures only and fields in the header have been removed.
-
-### Blockchain Protocol
-
-`TotalTxs` and `NumTxs` were removed from the header. `Commit` now consists
-mostly of just signatures.
-
-```go
-type Commit struct {
-	Height     int64
-	Round      int
-	BlockID    BlockID
-	Signatures []CommitSig
-}
-```
-
-```go
-type BlockIDFlag byte
-
-const (
-	// BlockIDFlagAbsent - no vote was received from a validator.
-	BlockIDFlagAbsent BlockIDFlag = 0x01
-	// BlockIDFlagCommit - voted for the Commit.BlockID.
-	BlockIDFlagCommit = 0x02
-	// BlockIDFlagNil - voted for nil.
-	BlockIDFlagNil = 0x03
-)
-
-type CommitSig struct {
-	BlockIDFlag      BlockIDFlag
-	ValidatorAddress Address
-	Timestamp        time.Time
-	Signature        []byte
-}
-```
-
-See [\#63](https://github.com/tendermint/spec/pull/63) for the complete spec
-change.
-
-### P2P Protocol
-
-The secret connection now includes a transcript hashing. If you want to
-implement a handshake (or otherwise have an existing implementation), you'll
-need to make the same changes that were made
-[here](https://github.com/tendermint/tendermint/pull/3668).
-
-### Config Changes
-
-You will need to generate a new config if you have used a prior version of tendermint.
-
-Tags have been entirely renamed throughout the codebase to events and there
-keys are called
-[compositeKeys](https://github.com/tendermint/tendermint/blob/6d05c531f7efef6f0619155cf10ae8557dd7832f/docs/app-dev/indexing-transactions.md).
-
-Evidence Params has been changed to include duration.
-
-* `consensus_params.evidence.max_age_duration`.
-* Renamed `consensus_params.evidence.max_age` to `max_age_num_blocks`.
-
-### Go API
-
-* `libs/common` has been removed in favor of specific pkgs.
-    * `async`
-    * `service`
-    * `rand`
-    * `net`
-    * `strings`
-    * `cmap`
-* removal of `errors` pkg
-
-### RPC Changes
-
-* `/validators` is now paginated (default: 30 vals per page)
-* `/block_results` response format updated [see RPC docs for details](https://docs.tendermint.com/master/rpc/#/Info/block_results)
-* Event suffix has been removed from the ID in event responses
-* IDs are now integers not `json-client-XYZ`
-
-## v0.32.0
-
-This release is compatible with previous blockchains,
-however the new ABCI Events mechanism may create some complexity
-for nodes wishing to continue operation with v0.32 from a previous version.
-There are some minor breaking changes to the RPC.
-
-### Config Changes
-
-If you have `db_backend` set to `leveldb` in your config file, please change it
-to `goleveldb` or `cleveldb`.
-
-### RPC Changes
-
-The default listen address for the RPC is now `127.0.0.1`. If you want to expose
-it publicly, you have to explicitly configure it. Note exposing the RPC to the
-public internet may not be safe - endpoints which return a lot of data may
-enable resource exhaustion attacks on your node, causing the process to crash.
-
-Any consumers of `/block_results` need to be mindful of the change in all field
-names from CamelCase to Snake case, eg. `results.DeliverTx` is now `results.deliver_tx`.
-This is a fix, but it's breaking.
-
-### ABCI Changes
-
-ABCI responses which previously had a `Tags` field now have an `Events` field
-instead. The original `Tags` field was simply a list of key-value pairs, where
-each key effectively represented some attribute of an event occuring in the
-blockchain, like `sender`, `receiver`, or `amount`. However, it was difficult to
-represent the occurence of multiple events (for instance, multiple transfers) in a single list.
-The new `Events` field contains a list of `Event`, where each `Event` is itself a list
-of key-value pairs, allowing for more natural expression of multiple events in
-eg. a single DeliverTx or EndBlock. Note each `Event` also includes a `Type`, which is meant to categorize the
-event.
-
-For transaction indexing, the index key is
-prefixed with the event type: `{eventType}.{attributeKey}`.
-If the same event type and attribute key appear multiple times, the values are
-appended in a list.
-
-To make queries, include the event type as a prefix. For instance if you
-previously queried for `recipient = 'XYZ'`, and after the upgrade you name your event `transfer`,
-the new query would be for `transfer.recipient = 'XYZ'`.
-
-Note that transactions indexed on a node before upgrading to v0.32 will still be indexed
-using the old scheme. For instance, if a node upgraded at height 100,
-transactions before 100 would be queried with `recipient = 'XYZ'` and
-transactions after 100 would be queried with `transfer.recipient = 'XYZ'`.
-While this presents additional complexity to clients, it avoids the need to
-reindex. Of course, you can reset the node and sync from scratch to re-index
-entirely using the new scheme.
-
-We illustrate further with a more complete example.
-
-Prior to the update, suppose your `ResponseDeliverTx` look like:
-
-```go
-abci.ResponseDeliverTx{
-  Tags: []kv.Pair{
-    {Key: []byte("sender"), Value: []byte("foo")},
-    {Key: []byte("recipient"), Value: []byte("bar")},
-    {Key: []byte("amount"), Value: []byte("35")},
-  }
-}
-```
-
-The following queries would match this transaction:
-
-```go
-query.MustParse("tm.event = 'Tx' AND sender = 'foo'")
-query.MustParse("tm.event = 'Tx' AND recipient = 'bar'")
-query.MustParse("tm.event = 'Tx' AND sender = 'foo' AND recipient = 'bar'")
-```
-
-Following the upgrade, your `ResponseDeliverTx` would look something like:
-the following `Events`:
-
-```go
-abci.ResponseDeliverTx{
-  Events: []abci.Event{
-    {
-      Type: "transfer",
-      Attributes: kv.Pairs{
-        {Key: []byte("sender"), Value: []byte("foo")},
-        {Key: []byte("recipient"), Value: []byte("bar")},
-        {Key: []byte("amount"), Value: []byte("35")},
-      },
-    }
-}
-```
-
-Now the following queries would match this transaction:
-
-```go
-query.MustParse("tm.event = 'Tx' AND transfer.sender = 'foo'")
-query.MustParse("tm.event = 'Tx' AND transfer.recipient = 'bar'")
-query.MustParse("tm.event = 'Tx' AND transfer.sender = 'foo' AND transfer.recipient = 'bar'")
-```
-
-For further documentation on `Events`, see the [docs](https://github.com/tendermint/tendermint/blob/60827f75623b92eff132dc0eff5b49d2025c591e/docs/spec/abci/abci.md#events).
-
-### Go Applications
-
-The ABCI Application interface changed slightly so the CheckTx and DeliverTx
-methods now take Request structs. The contents of these structs are just the raw
-tx bytes, which were previously passed in as the argument.
-
-## v0.31.6
-
-There are no breaking changes in this release except Go API of p2p and
-mempool packages. Hovewer, if you're using cleveldb, you'll need to change
-the compilation tag:
-
-Use `cleveldb` tag instead of `gcc` to compile Tendermint with CLevelDB or
-use `make build_c` / `make install_c` (full instructions can be found at
-<https://tendermint.com/docs/introduction/install.html#compile-with-cleveldb-support>)
-
-## v0.31.0
-
-This release contains a breaking change to the behaviour of the pubsub system.
-It also contains some minor breaking changes in the Go API and ABCI.
-There are no changes to the block or p2p protocols, so v0.31.0 should work fine
-with blockchains created from the v0.30 series.
-
-### RPC
-
-The pubsub no longer blocks on publishing. This may cause some WebSocket (WS) clients to stop working as expected.
-If your WS client is not consuming events fast enough, Tendermint can terminate the subscription.
-In this case, the WS client will receive an error with description:
-
-```json
-{
-  "jsonrpc": "2.0",
-  "id": "{ID}#event",
-  "error": {
-    "code": -32000,
-    "msg": "Server error",
-    "data": "subscription was canceled (reason: client is not pulling messages fast enough)" // or "subscription was canceled (reason: Tendermint exited)"
-  }
-}
-
-Additionally, there are now limits on the number of subscribers and
-subscriptions that can be active at once. See the new
-`rpc.max_subscription_clients` and `rpc.max_subscriptions_per_client` values to
-configure this.
-```
-
-### Applications
-
-Simple rename of `ConsensusParams.BlockSize` to `ConsensusParams.Block`.
-
-The `ConsensusParams.Block.TimeIotaMS` field was also removed. It's configured
-in the ConsensusParsm in genesis.
-
-### Go API
-
-See the [CHANGELOG](CHANGELOG.md). These are relatively straight forward.
-
-## v0.30.0
-
-This release contains a breaking change to both the block and p2p protocols,
-however it may be compatible with blockchains created with v0.29.0 depending on
-the chain history. If your blockchain has not included any pieces of evidence,
-or no piece of evidence has been included in more than one block,
-and if your application has never returned multiple updates
-for the same validator in a single block, then v0.30.0 will work fine with
-blockchains created with v0.29.0.
-
-The p2p protocol change is to fix the proposer selection algorithm again.
-Note that proposer selection is purely a p2p concern right
-now since the algorithm is only relevant during real time consensus.
-This change is thus compatible with v0.29.0, but
-all nodes must be upgraded to avoid disagreements on the proposer.
-
-### Applications
-
-Applications must ensure they do not return duplicates in
-`ResponseEndBlock.ValidatorUpdates`. A pubkey must only appear once per set of
-updates. Duplicates will cause irrecoverable failure. If you have a very good
-reason why we shouldn't do this, please open an issue.
-
-## v0.29.0
-
-This release contains some breaking changes to the block and p2p protocols,
-and will not be compatible with any previous versions of the software, primarily
-due to changes in how various data structures are hashed.
-
-Any implementations of Tendermint blockchain verification, including lite clients,
-will need to be updated. For specific details:
-
-* [Merkle tree](https://github.com/tendermint/spec/blob/master/spec/blockchain/encoding.md#merkle-trees)
-* [ConsensusParams](https://github.com/tendermint/spec/blob/master/spec/blockchain/state.md#consensusparams)
-
-There was also a small change to field ordering in the vote struct. Any
-implementations of an out-of-process validator (like a Key-Management Server)
-will need to be updated. For specific details:
-
-* [Vote](https://github.com/tendermint/spec/blob/master/spec/consensus/signing.md#votes)
-
-Finally, the proposer selection algorithm continues to evolve. See the
-[work-in-progress
-specification](https://github.com/tendermint/tendermint/pull/3140).
-
-For everything else, please see the [CHANGELOG](./CHANGELOG.md#v0.29.0).
-
-## v0.28.0
-
-This release breaks the format for the `priv_validator.json` file
-and the protocol used for the external validator process.
-It is compatible with v0.27.0 blockchains (neither the BlockProtocol nor the
-P2PProtocol have changed).
-
-Please read carefully for details about upgrading.
-
-**Note:** Backup your `config/priv_validator.json`
-before proceeding.
-
-### `priv_validator.json`
-
-The `config/priv_validator.json` is now two files:
-`config/priv_validator_key.json` and `data/priv_validator_state.json`.
-The former contains the key material, the later contains the details on the last
-message signed.
-
-When running v0.28.0 for the first time, it will back up any pre-existing
-`priv_validator.json` file and proceed to split it into the two new files.
-Upgrading should happen automatically without problem.
-
-To upgrade manually, use the provided `privValUpgrade.go` script, with exact paths for the old
-`priv_validator.json` and the locations for the two new files. It's recomended
-to use the default paths, of `config/priv_validator_key.json` and
-`data/priv_validator_state.json`, respectively:
-
-```sh
-go run scripts/privValUpgrade.go <old-path> <new-key-path> <new-state-path>
-```
-
-### External validator signers
-
-The Unix and TCP implementations of the remote signing validator
-have been consolidated into a single implementation.
-Thus in both cases, the external process is expected to dial
-Tendermint. This is different from how Unix sockets used to work, where
-Tendermint dialed the external process.
-
-The `PubKeyMsg` was also split into separate `Request` and `Response` types
-for consistency with other messages.
-
-Note that the TCP sockets don't yet use a persistent key,
-so while they're encrypted, they can't yet be properly authenticated.
-See [#3105](https://github.com/tendermint/tendermint/issues/3105).
-Note the Unix socket has neither encryption nor authentication, but will
-add a shared-secret in [#3099](https://github.com/tendermint/tendermint/issues/3099).
-
-## v0.27.0
-
-This release contains some breaking changes to the block and p2p protocols,
-but does not change any core data structures, so it should be compatible with
-existing blockchains from the v0.26 series that only used Ed25519 validator keys.
-Blockchains using Secp256k1 for validators will not be compatible. This is due
-to the fact that we now enforce which key types validators can use as a
-consensus param. The default is Ed25519, and Secp256k1 must be activated
-explicitly.
-
-It is recommended to upgrade all nodes at once to avoid incompatibilities at the
-peer layer - namely, the heartbeat consensus message has been removed (only
-relevant if `create_empty_blocks=false` or `create_empty_blocks_interval > 0`),
-and the proposer selection algorithm has changed. Since proposer information is
-never included in the blockchain, this change only affects the peer layer.
-
-### Go API Changes
-
-#### libs/db
-
-The ReverseIterator API has changed the meaning of `start` and `end`.
-Before, iteration was from `start` to `end`, where
-`start > end`. Now, iteration is from `end` to `start`, where `start < end`.
-The iterator also excludes `end`. This change allows a simplified and more
-intuitive logic, aligning the semantic meaning of `start` and `end` in the
-`Iterator` and `ReverseIterator`.
-
-### Applications
-
-This release enforces a new consensus parameter, the
-ValidatorParams.PubKeyTypes. Applications must ensure that they only return
-validator updates with the allowed PubKeyTypes. If a validator update includes a
-pubkey type that is not included in the ConsensusParams.Validator.PubKeyTypes,
-block execution will fail and the consensus will halt.
-
-By default, only Ed25519 pubkeys may be used for validators. Enabling
-Secp256k1 requires explicit modification of the ConsensusParams.
-Please update your application accordingly (ie. restrict validators to only be
-able to use Ed25519 keys, or explicitly add additional key types to the genesis
-file).
-
-## v0.26.0
-
-This release contains a lot of changes to core data types and protocols. It is not
-compatible to the old versions and there is no straight forward way to update
-old data to be compatible with the new version.
-
-To reset the state do:
-
-```sh
-tendermint unsafe_reset_all
-```
-
-Here we summarize some other notable changes to be mindful of.
-
-### Config Changes
-
-All timeouts must be changed from integers to strings with their duration, for
-instance `flush_throttle_timeout = 100` would be changed to
-`flush_throttle_timeout = "100ms"` and `timeout_propose = 3000` would be changed
-to `timeout_propose = "3s"`.
-
-### RPC Changes
-
-The default behaviour of `/abci_query` has been changed to not return a proof,
-and the name of the parameter that controls this has been changed from `trusted`
-to `prove`. To get proofs with your queries, ensure you set `prove=true`.
-
-Various version fields like `amino_version`, `p2p_version`, `consensus_version`,
-and `rpc_version` have been removed from the `node_info.other` and are
-consolidated under the tendermint semantic version (ie. `node_info.version`) and
-the new `block` and `p2p` protocol versions under `node_info.protocol_version`.
-
-### ABCI Changes
-
-Field numbers were bumped in the `Header` and `ResponseInfo` messages to make
-room for new `version` fields. It should be straight forward to recompile the
-protobuf file for these changes.
-
-#### Proofs
-
-The `ResponseQuery.Proof` field is now structured as a `[]ProofOp` to support
-generalized Merkle tree constructions where the leaves of one Merkle tree are
-the root of another. If you don't need this functionality, and you used to
-return `<proof bytes>` here, you should instead return a single `ProofOp` with
-just the `Data` field set:
-
-```go
-[]ProofOp{
-    ProofOp{
-        Data: <proof bytes>,
-    }
-}
-```
-

-
-### Go API Changes
-
-#### crypto/merkle
-
-The `merkle.Hasher` interface was removed. Functions which used to take `Hasher`
-now simply take `[]byte`. This means that any objects being Merklized should be
-serialized before they are passed in.
-
-#### node
-
-The `node.RunForever` function was removed. Signal handling and running forever
-should instead be explicitly configured by the caller. See how we do it
-[here](https://github.com/tendermint/tendermint/blob/30519e8361c19f4bf320ef4d26288ebc621ad725/cmd/tendermint/commands/run_node.go#L60).
-
-### Other
-
-All hashes, except for public key addresses, are now 32-bytes.
-
-## v0.25.0
-
-This release has minimal impact.
-
-If you use GasWanted in ABCI and want to enforce it, set the MaxGas in the genesis file (default is no max).
-
-## v0.24.0
-
-New 0.24.0 release contains a lot of changes to the state and types. It's not
-compatible to the old versions and there is no straight forward way to update
-old data to be compatible with the new version.
-
-To reset the state do:
-
-```sh
-tendermint unsafe_reset_all
-```
-
-Here we summarize some other notable changes to be mindful of.
-
-### Config changes
-
-`p2p.max_num_peers` was removed in favor of `p2p.max_num_inbound_peers` and
-`p2p.max_num_outbound_peers`.
-
-```toml
-# Maximum number of inbound peers
-max_num_inbound_peers = 40
-
-# Maximum number of outbound peers to connect to, excluding persistent peers
-max_num_outbound_peers = 10
-```
-
-As you can see, the default ratio of inbound/outbound peers is 4/1. The reason
-is we want it to be easier for new nodes to connect to the network. You can
-tweak these parameters to alter the network topology.
-
-### RPC Changes
-
-The result of `/commit` used to contain `header` and `commit` fields at the top level. These are now contained under the `signed_header` field.
-
-### ABCI Changes
-
-The header has been upgraded and contains new fields, but none of the existing
-fields were changed, except their order.
-
-The `Validator` type was split into two, one containing an `Address` and one
-containing a `PubKey`. When processing `RequestBeginBlock`, use the `Validator`
-type, which contains just the `Address`. When returning `ResponseEndBlock`, use
-the `ValidatorUpdate` type, which contains just the `PubKey`.
-
-### Validator Set Updates
-
-Validator set updates returned in ResponseEndBlock for height `H` used to take
-effect immediately at height `H+1`. Now they will be delayed one block, to take
-effect at height `H+2`. Note this means that the change will be seen by the ABCI
-app in the `RequestBeginBlock.LastCommitInfo` at block `H+3`. Apps were already
-required to maintain a map from validator addresses to pubkeys since v0.23 (when
-pubkeys were removed from RequestBeginBlock), but now they may need to track
-multiple validator sets at once to accomodate this delay.
-
-### Block Size
-
-The `ConsensusParams.BlockSize.MaxTxs` was removed in favour of
-`ConsensusParams.BlockSize.MaxBytes`, which is now enforced. This means blocks
-are limitted only by byte-size, not by number of transactions.

-# Application BlockChain Interface (ABCI)
-
-Blockchains are systems for multi-master state machine replication.
-**ABCI** is an interface that defines the boundary between the replication engine (the blockchain),
-and the state machine (the application).
-Using a socket protocol, a consensus engine running in one process
-can manage an application state running in another.
-
-Previously, the ABCI was referred to as TMSP.
-
-The community has provided a number of additional implementations, see the [Tendermint Ecosystem](https://github.com/tendermint/awesome#ecosystem)
-
-
-## Installation & Usage
-
-To get up and running quickly, see the [getting started guide](../docs/app-dev/getting-started.md) along with the [abci-cli documentation](../docs/app-dev/abci-cli.md) which will go through the examples found in the [examples](./example/) directory.
-
-## Specification
-
-A detailed description of the ABCI methods and message types is contained in:
-
-- [The main spec](https://github.com/tendermint/spec/blob/master/spec/abci/abci.md)
-- [A protobuf file](../proto/tendermint/abci/types.proto)
-- [A Go interface](./types/application.go)
-
-## Protocol Buffers
-
-To compile the protobuf file, run (from the root of the repo):
-
-```sh
-make protoc_abci
-```
-
-See `protoc --help` and [the Protocol Buffers site](https://developers.google.com/protocol-buffers)
-for details on compiling for other languages. Note we also include a [GRPC](https://www.grpc.io/docs)
-service definition.

-// ## gRPC client

-# KVStore
-
-There are two app's here: the KVStoreApplication and the PersistentKVStoreApplication.
-
-## KVStoreApplication
-
-The KVStoreApplication is a simple merkle key-value store. 
-Transactions of the form `key=value` are stored as key-value pairs in the tree.
-Transactions without an `=` sign set the value to the key.
-The app has no replay protection (other than what the mempool provides).
-
-## PersistentKVStoreApplication
-
-The PersistentKVStoreApplication wraps the KVStoreApplication
-and provides two additional features:
-
-1) persistence of state across app restarts (using Tendermint's ABCI-Handshake mechanism)
-2) validator set changes
-
-The state is persisted in leveldb along with the last block committed,
-and the Handshake allows any necessary blocks to be replayed.
-Validator set changes are effected using the following transaction format:
-
-```md
-"val:pubkey1!power1,pubkey2!power2,pubkey3!power3"
-```
-
-where `pubkeyN` is a base64-encoded 32-byte ed25519 key and `powerN` is a new voting power for the validator with `pubkeyN` (possibly a new one).
-To remove a validator from the validator set, set power to `0`.
-There is no sybil protection against new validators joining.
