+
+Special thanks to external contributors on this release: @JayT106,
+@bipulprasad, @alessio, @Yawning, @silasdavis, @cuonglm, @tanyabouman,
+@JoeKash, @githubsands, @jeebster, @crypto-facs, @liamsi, and @gotjoshua

+  - `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`.

+
+### BUG FIXES
+
+- [\#7106](https://github.com/tendermint/tendermint/pull/7106) Revert mutex change to ABCI Clients (@tychoish).
+- [\#7142](https://github.com/tendermint/tendermint/pull/7142) mempool: remove panic when recheck-tx was not sent to ABCI application (@williambanfield).
+- [consensus]: [\#7060](https://github.com/tendermint/tendermint/pull/7060)
+  wait until peerUpdates channel is closed to close remaining peers (@williambanfield)
+- [privval] [\#5638](https://github.com/tendermint/tendermint/pull/5638) Increase read/write timeout to 5s and calculate ping interval based on it (@JoeKash)

+    library. (@tychoish)
+  - [state] [store] [proxy] [rpc/core]: [\#6937](https://github.com/tendermint/tendermint/pull/6937) move packages to
+    `internal` to prevent consumption of these internal APIs by
+    external users. (@tychoish)
+  - [pubsub] [\#6634](https://github.com/tendermint/tendermint/pull/6634) The `Query#Matches` method along with other pubsub methods, now accepts a `[]abci.Event` instead of `map[string][]string`. (@alexanderbez)
+  - [p2p] [\#6618](https://github.com/tendermint/tendermint/pull/6618) [\#6583](https://github.com/tendermint/tendermint/pull/6583) Move `p2p.NodeInfo`, `p2p.NodeID` and `p2p.NetAddress` into `types` to support use in external packages. (@tychoish)

-### Release Procedure
+### Release procedure
 
-#### Major Release
+#### A note about backport branches
+Tendermint's `master` branch is under active development.
+Releases are specified using tags and are built from long-lived "backport" branches.
+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. There should be a label for any backport branch that you'll be targeting.
+To notify the bot to backport a pull request, mark the pull request with
+the label `S: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.
+
+#### Creating a backport branch
+
+If this is the first release candidate for a major release, you get to have the honor of creating
+the backport branch!
+
+Note that, after creating the backport branch, you'll also need to update the tags on `master`
+so that `go mod` is able to order the branches correctly. You should tag `master` with a "dev" tag
+that is "greater than" the backport branches tags. See #6072 for more context.
+
+In the following example, we'll assume that we're making a backport branch for
+the 0.35.x line.
+
+1. Start on `master`
+2. Create the backport branch:
+   `git checkout -b v0.35.x`
+3. Go back to master and tag it as the dev branch for the _next_ major release and push it back up:
+   `git tag -a v0.36.0-dev; git push v0.36.0-dev`
+4. Create a new workflow to run the e2e nightlies for this backport branch.
+   (See https://github.com/tendermint/tendermint/blob/master/.github/workflows/e2e-nightly-34x.yml
+   for an example.)
+
+#### 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 backport branches.
+
+Tags for RCs should follow the "standard" release naming conventions, with `-rcX` at the end
+(for example, `v0.35.0-rc0`).
+
+(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.)
+
+If this is the first RC for a major release, you'll have to make a new backport branch (see above).
+Otherwise:
+
+1. Start from the backport branch (e.g. `v0.35.x`).
+1. Run the integration tests and the e2e nightlies
+   (which can be triggered from the Github UI;
+   e.g., https://github.com/tendermint/tendermint/actions/workflows/e2e-nightly-34x.yml).
+1. Prepare the changelog:
+   - Move the changes included in `CHANGELOG_PENDING.md` into `CHANGELOG.md`.
+   - 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
+1. Open a PR with these changes against the backport branch.
+1. Once these changes have landed on the backport branch, be sure to pull them back down locally.
+2. Once you have the changes locally, create the new tag, specifying a name and a tag "message":
+   `git tag -a v0.35.0-rc0 -m "Release Candidate v0.35.0-rc0`
+3. Push the tag back up to origin:
+   `git push origin v0.35.0-rc0`
+   Now the tag should be available on the repo's releases page.
+4. Future RCs will continue to be built off of this branch.
+
+Note that this process should only be used for "true" RCs--
+release candidates that, if successful, will be the next release.
+For more experimental "RCs," create a new, short-lived branch and tag that instead.
+
+#### Major release
 
 This major release process assumes that this release was preceded by release candidates.

-#### Minor Release (Point Releases)
+#### 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).

-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.

 This guide provides instructions for upgrading to specific versions of Tendermint Core.
 
-## Unreleased
+## v0.35
 
 ### 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.
+* The configuration file field `[fastsync]` has been renamed to `[blocksync]`.
+
+* The top level configuration file field `fast-sync` has moved under the new `[blocksync]`
+  field as `blocksync.enable`.
+
+* `blocksync.version = "v1"` and `blocksync.version = "v2"` (previously `fastsync`)
+  are no longer supported. Please use `v0` instead. During the v0.35 release cycle, `v0` was
+  determined to suit the existing needs and the cost of maintaining the `v1` and `v2` modules
+  was determined to be greater than necessary.
+
 
 * 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. 
+  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.
+
+* The fast sync process as well as the blockchain package and service has all
+  been renamed to block sync
+
+* We have added a new, experimental tool to help operators migrate
+  configuration files created by previous versions of Tendermint.
+  To try this tool, run:
+
+  ```shell
+  # Install the tool.
+  go install github.com/tendermint/tendermint/scripts/confix@v0.35.x
+
+  # Run the tool with the old configuration file as input.
+  # Replace the -config argument with your path.
+  confix -config ~/.tendermint/config/config.toml -out updated.toml
+  ```
+
+  This tool should be able to update configurations from v0.34 to v0.35.  We
+  plan to extend it to handle older configuration files in the future. For now,
+  it will report an error (without making any changes) if it does not recognize
+  the version that created the file.
+
+### Database Key Format Changes
+
+The format of all tendermint on-disk database keys changes in
+0.35. Upgrading nodes must either re-sync all data or run a migration
+script provided in this release.
+
+The script located in
+`github.com/tendermint/tendermint/scripts/keymigrate/migrate.go` provides the
+function `Migrate(context.Context, db.DB)` which you can operationalize as
+makes sense for your deployment.
+
+For ease of use the `tendermint` command includes a CLI version of the
+migration script, which you can invoke, as in:
+
+	tendermint key-migrate
+
+This reads the configuration file as normal and allows the `--db-backend` and
+`--db-dir` flags to override the database location as needed.
+
+The migration operation is intended to be idempotent, and should be safe to
+rerun on the same database multiple times.  As a safety measure, however, we
+recommend that operators test out the migration on a copy of the database
+first, if it is practical to do so, before applying it to the production data.
 
 ### CLI Changes
 
+* You must now specify the node mode (validator|full|seed) in `tendermint init [mode]`
+
+* The `--fast-sync` command line option has been renamed to `--blocksync.enable`
+
 * 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` or pipe the output of `tendermint gen_node_key` to
+  `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.

+
+### API Changes
+
+The p2p layer was reimplemented as part of the 0.35 release cycle and
+all reactors were refactored to accomodate the change. 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 `node` package 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.
+
+To access any of the functionality previously available via the
+`node.Node` type, use the `*local.Local` "RPC" client, that exposes
+the full RPC interface provided as direct function calls. Import the
+`github.com/tendermint/tendermint/rpc/client/local` package and pass
+the node service as in the following:
+
+```go
+    node := node.NewDefault() //construct the node object
+    // start and set up the node service
+
+    client := local.New(node.(local.NodeService))
+    // use client object to interact with the node
+```
+
+### gRPC Support
+
+Mark gRPC in the RPC layer as deprecated and to be removed in 0.36.
+
+### Peer Management Interface
+
+When running with the new P2P Layer, the methods `UnsafeDialSeeds` and
+`UnsafeDialPeers` RPC methods will always return an error. They are
+deprecated and will be removed in 0.36 when the legacy peer stack is
+removed.
+
+Additionally the format of the Peer list returned in the `NetInfo`
+method changes in this release to accommodate the different way that
+the new stack tracks data about peers. This change affects users of
+both stacks.
+
+### Using the updated p2p library
+
+The P2P library was reimplemented in this release. The new implementation is
+enabled by default in this version of Tendermint. The legacy implementation is still
+included in this version of Tendermint as a backstop to work around unforeseen
+production issues. The new and legacy version are interoperable. If necessary,
+you can enable the legacy implementation in the server configuration file.
+
+To make use of the legacy P2P implemementation add or update the following field of
+your server's configuration file under the `[p2p]` section:
+
+```toml
+[p2p]
+...
+use-legacy = true
+...
+```
+
+If you need to do this, please consider filing an issue in the Tendermint repository
+to let us know why. We plan to remove the legacy P2P code in the next (v0.36) release.
+
+#### New p2p queue types
+
+The new p2p implementation enables selection of the queue type to be used for
+passing messages between peers.
+
+The following values may be used when selecting which queue type to use:
+
+* `fifo`: (**default**) An unbuffered and lossless queue that passes messages through
+in the order in which they were received.
+
+* `priority`: A priority queue of messages.
+
+* `wdrr`: A queue implementing the Weighted Deficit Round Robin algorithm. A
+weighted deficit round robin queue is created per peer. Each queue contains a
+separate 'flow' for each of the channels of communication that exist between any two
+peers. Tendermint maintains a channel per message type between peers. Each WDRR
+queue maintains a shared buffered with a fixed capacity through which messages on different
+flows are passed.
+For more information on WDRR scheduling, see: https://en.wikipedia.org/wiki/Deficit_round_robin
+
+To select a queue type, add or update the following field under the `[p2p]`
+section of your server's configuration file.
+
+```toml
+[p2p]
+...
+queue-type = wdrr
+...
+```
+
+
+### Support for Custom Reactor and Mempool Implementations
+
+The changes to p2p layer removed existing support for custom
+reactors. Based on our understanding of how this functionality was
+used, the introduction of the prioritized mempool covers nearly all of
+the use cases for custom reactors. If you are currently running custom
+reactors and mempools and are having trouble seeing the migration path
+for your project please feel free to reach out to the Tendermint Core
+development team directly.
+
 ## 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 1.15 or higher.
