+
+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)

+
+- Go API
+
+  - [crypto/armor]: [\#6963](https://github.com/tendermint/tendermint/pull/6963) remove package which is unused, and based on
+    deprecated fundamentals. Downstream users should maintain this
+    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)
+  - [node] [\#6540](https://github.com/tendermint/tendermint/pull/6540) Reduce surface area of the `node` package by making most of the implementation details private. (@tychoish)
+  - [p2p] [\#6547](https://github.com/tendermint/tendermint/pull/6547) Move the entire `p2p` package and all reactor implementations into `internal`.  (@tychoish)
+  - [libs/log] [\#6534](https://github.com/tendermint/tendermint/pull/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](https://github.com/tendermint/tendermint/pull/6495) Move types/time to libs/time to improve consistency. (@tychoish)
+  - [mempool] [\#6529](https://github.com/tendermint/tendermint/pull/6529) The `Context` field has been removed from the `TxInfo` type. `CheckTx` now requires a `Context` argument. (@alexanderbez)
+  - [abci/client, proxy] [\#5673](https://github.com/tendermint/tendermint/pull/5673) `Async` funcs return an error, `Sync` and `Async` funcs accept `context.Context` (@melekes)
+  - [p2p] Remove unused function `MakePoWTarget`. (@erikgrinaker)
+  - [libs/bits] [\#5720](https://github.com/tendermint/tendermint/pull/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)

-### 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).

 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.

-   Now the tag should be available on the repo's releases page.

-## 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.
 
 * 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. 
+  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 validator` or pipe the output of `tendermint gen_node_key` to

+
+### 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.
