 Friendly reminder, we have a [bug bounty program](https://hackerone.com/cosmos).
 
-## v0.34.24
-
-*Nov 22, 2022*
-
-Apart from one minor bug fix, this release aims to optimize the output of the
-RPC (both HTTP and WebSocket endpoints). See our [upgrading
-guidelines](./UPGRADING.md#v03424) for more details.
-
-### IMPROVEMENTS
-
-- `[rpc]` [\#9724](https://github.com/tendermint/tendermint/issues/9724) Remove
-  useless whitespace in RPC output (@adizere, @thanethomson)
-
-### BUG FIXES
-
-- `[rpc]` [\#9692](https://github.com/tendermint/tendermint/issues/9692) Remove
-  `Cache-Control` header response from `/check_tx` endpoint (@JayT106)
-
-## v0.34.23
-
-*Nov 9, 2022*
-
-This release introduces some new Prometheus metrics to help in determining what
-kinds of messages are consuming the most P2P bandwidth. This builds towards our
-broader goal of optimizing Tendermint bandwidth consumption, and will give us
-meaningful insights once we can establish these metrics for a number of chains.
-
-We now also return `Cache-Control` headers for select RPC endpoints to help
-facilitate caching.
-
-Special thanks to external contributors on this release: @JayT106
-
-### IMPROVEMENTS
-- `[p2p]` [\#9641](https://github.com/tendermint/tendermint/issues/9641) Add new
-  Envelope type and associated methods for sending and receiving Envelopes
-  instead of raw bytes. This also adds new metrics,
-  `tendermint_p2p_message_send_bytes_total` and
-  `tendermint_p2p_message_receive_bytes_total`, that expose how many bytes of
-  each message type have been sent.
-- `[rpc]` [\#9666](https://github.com/tendermint/tendermint/issues/9666) Enable
-  caching of RPC responses (@JayT106)
-
-  The following RPC endpoints will return `Cache-Control` headers with a maximum
-  age of 1 day:
-
-  - `/abci_info`
-  - `/block`, if `height` is supplied
-  - `/block_by_hash`
-  - `/block_results`, if `height` is supplied
-  - `/blockchain`
-  - `/check_tx`
-  - `/commit`, if `height` is supplied
-  - `/consensus_params`, if `height` is supplied
-  - `/genesis`
-  - `/genesis_chunked`
-  - `/tx`

-## v0.34.22
-
-This release includes several bug fixes, [one of
-which](https://github.com/tendermint/tendermint/pull/9518) we discovered while
-building up a baseline for v0.34 against which to compare our upcoming v0.37
-release during our [QA process](./docs/qa/).
-
-Special thanks to external contributors on this release: @RiccardoM
-
-### FEATURES
-
-- [rpc] [\#9423](https://github.com/tendermint/tendermint/pull/9423) Support
-  HTTPS URLs from the WebSocket client (@RiccardoM, @cmwaters)
-
-### BUG FIXES
-
-- [config] [\#9483](https://github.com/tendermint/tendermint/issues/9483)
-  Calling `tendermint init` would incorrectly leave out the new `[storage]`
-  section delimiter in the generated configuration file - this has now been
-  fixed
-- [p2p] [\#9500](https://github.com/tendermint/tendermint/issues/9500) Prevent
-  peers who have errored being added to the peer set (@jmalicevic)
-- [indexer] [\#9473](https://github.com/tendermint/tendermint/issues/9473) Fix
-  bug that caused the psql indexer to index empty blocks whenever one of the
-  transactions returned a non zero code. The relevant deduplication logic has
-  been moved within the kv indexer only (@cmwaters)
-- [blocksync] [\#9518](https://github.com/tendermint/tendermint/issues/9518) A
-  block sync stall was observed during our QA process whereby the node was
-  unable to make progress. Retrying block requests after a timeout fixes this.
-
-## v0.34.21
-
-Release highlights include:
-
-- A new `[storage]` configuration section and flag `discard_abci_responses`,
-  which, if enabled, discards all ABCI responses except the latest one in order
-  to reduce disk space usage in the state store. When enabled, the
-  `block_results` RPC endpoint can no longer function and will return an error.
-- A new CLI command, `reindex-event`, to re-index block and tx events to the
-  event sinks. You can run this command when the event store backend
-  dropped/disconnected or you want to replace the backend. When
-  `discard_abci_responses` is enabled, you will not be able to use this command.

 - Apps
-  - [abci/counter] \#6684 Delete counter example app
-  - [abci] \#5783 Make length delimiter encoding consistent (`uint64`) between ABCI and P2P wire-level protocols
-  - [abci] \#9145 Removes unused Response/Request `SetOption` from ABCI (@samricotta)
-  - [abci/params] \#9287 Deduplicate `ConsensusParams` and `BlockParams` so only `types` proto definitions are used (@cmwaters)
-    - Remove `TimeIotaMs` and use a hard-coded 1 millisecond value to ensure monotonically increasing block times.
-    - Rename `AppVersion` to `App` so as to not stutter.
-  - [types] \#9287 Reduce the use of protobuf types in core logic. (@cmwaters)
-    - `ConsensusParams`, `BlockParams`, `ValidatorParams`, `EvidenceParams`, `VersionParams` have become native types.
-      They still utilize protobuf when being sent over the wire or written to disk.
-    - Moved `ValidateConsensusParams` inside (now native type) `ConsensusParams`, and renamed it to `ValidateBasic`.
-  - [abci] \#9301 New ABCI methods `PrepareProposal` and `ProcessProposal` which give the app control over transactions proposed and allows for verification of proposed blocks.
-  - [abci] \#8216 Renamed `EvidenceType` to `MisbehaviorType` and `Evidence` to `Misbehavior` as a more accurate label of their contents. (@williambanfield, @sergio-mena)
-  - [abci] \#9122 Renamed `LastCommitInfo` to `CommitInfo` in preparation for vote extensions. (@cmwaters)
-  - [abci] \#8656, \#8901 Added cli commands for `PrepareProposal` and `ProcessProposal`. (@jmalicevic, @hvanz)

 ### IMPROVEMENTS
-- [crypto] \#9250 Update to use btcec v2 and the latest btcutil. (@wcsiu)
-
-- [cli] \#9171 add `--hard` flag to rollback command (and a boolean to the `RollbackState` method). This will rollback
-  state and remove the last block. This command can be triggered multiple times. The application must also rollback
-  state to the same height. (@tsutsu, @cmwaters)

-- [types] \#6120 use batch verification for verifying commits signatures. (@marbar3778 & @cmwaters & @Yawning)
-    - 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.
-- [state] \#9505 Added logic so when pruning, the evidence period is taken into consideration and only deletes unecessary data (@samricotta)

 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.

+
+### Release Procedure
+
+#### Major Release
+
+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
+
+Minor releases are done differently from major releases: They are built off of long-lived release candidate branches, rather than from master.
+
+1. Checkout the long-lived release candidate branch: `git checkout rcX/vX.X.X`
+2. Run integration tests: `make test_integrations`
+3. 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 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. Create a release branch `release/vX.X.x` off the release candidate branch:
+   - `git checkout -b release/vX.X.x`
+   - `git push -u origin release/vX.X.x`
+   - Note that all branches prefixed with `release` are protected once pushed. You will need admin help to make any changes to the branch.
+5. Once the release branch has been approved, 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 release branch into master.
+7. Delete the former long lived release candidate branch once the release has been made.
+8. Create a new release candidate branch to be used for the next release.
+
+#### Backport Release
+
+1. start from the existing release branch you want to backport changes to (e.g. v0.30)
+   Branch to a release/vX.X.X branch locally (e.g. release/v0.30.7)
+2. Cherry pick the commit(s) that contain the changes you want to backport (usually these commits are from squash-merged PRs which were already reviewed)
+3. Follow steps 2 and 3 from [Major Release](#major-release)
+4. Push changes to release/vX.X.X branch
+5. Open a PR against the existing vX.X branch
+
+#### 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`

 ## 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
+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 users of 0.X.X versions of Tendermint, the MINOR
-version is used to signal breaking changes across Tendermint's API. This API
-includes all publicly exposed types, functions, and methods in non-internal Go
-packages as well as the types and methods accessible via the Tendermint RPC
-interface.
+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.
 
-Breaking changes to these public APIs will be documented in the CHANGELOG.
+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
+    - bech32
+    - 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.

 ### Supported Versions
 
-Because we are a small core team, we have limited capacity to ship patch
-updates, including security updates. Consequently, we strongly recommend keeping
-Tendermint up-to-date. Upgrading instructions can be found in
-[UPGRADING.md](./UPGRADING.md).
-
-Currently supported versions include:
-
-- v0.34.x
-- v0.37.x (release candidate)
+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

-# Releases
-
-Tendermint uses modified [semantic versioning](https://semver.org/) with each
-release following a `vX.Y.Z` format. Tendermint is currently on major version 0
-and uses the minor version to signal breaking changes. The `main` branch is
-used for active development and thus it is not advisable to build against it.
-
-The latest changes are always initially merged into `main`. Releases are
-specified using tags and are built from long-lived "backport" branches that are
-cut from `main` when the release process begins. 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). Tendermint only maintains the last two releases at a time (the
-oldest release is predominantly just security patches).
-
-## Backporting
-
-As non-breaking changes land on `main`, they should also be backported 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 corresponding to the correct
-backport branch. For example, to backport to v0.38.x, add the label
-`S:backport-to-v0.38.x`. 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 minor version release, e.g.
-v0.25.0, 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 `main` so that `go mod` is able to order the branches correctly. You
-should tag `main` with a "dev" tag that is "greater than" the backport
-branches tags. See [#6072](https://github.com/tendermint/tendermint/pull/6072)
-for more context.
-
-In the following example, we'll assume that we're making a backport branch for
-the 0.38.x line.
-
-1. Start on `main`
-
-2. Ensure that there is a [branch protection
-   rule](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests/managing-a-branch-protection-rule) for the
-   branch you are about to create (you will need admin access to the repository
-   in order to do this).
-
-3. Create and push the backport branch:
-   ```sh
-   git checkout -b v0.38.x
-   git push origin v0.38.x
-   ```
-
-4. Create a PR to update the documentation directory for the backport branch.
-
-   We rewrite any URLs pointing to `main` to point to the backport branch,
-   so that generated documentation will link to the correct versions of files
-   elsewhere in the repository. The following files are to be excluded from this
-   search:
-
-   * [`README.md`](./README.md)
-   * [`CHANGELOG.md`](./CHANGELOG.md)
-   * [`UPGRADING.md`](./UPGRADING.md)
-
-   The following links are to always point to `main`, regardless of where they
-   occur in the codebase:
-
-   * `https://github.com/tendermint/tendermint/blob/main/LICENSE`
-
-   Be sure to search for all of the following links and replace `main` with your
-   corresponding branch label or version (e.g. `v0.38.x` or `v0.38`):
-
-   * `github.com/tendermint/tendermint/blob/main` ->
-     `github.com/tendermint/tendermint/blob/v0.38.x`
-   * `github.com/tendermint/tendermint/tree/main` ->
-     `github.com/tendermint/tendermint/tree/v0.38.x`
-   * `docs.tendermint.com/main` -> `docs.tendermint.com/v0.38`
-
-   Once you have updated all of the relevant documentation:
-   ```sh
-   # Create and push the PR.
-   git checkout -b update-docs-v038x
-   git commit -m "Update docs for v0.38.x backport branch."
-   git push -u origin update-docs-v038x
-   ```
-
-   Be sure to merge this PR before making other changes on the newly-created
-   backport branch.
-
-After doing these steps, go back to `main` and do the following:
-
-1. Create a new workflow to run e2e nightlies for the new backport branch. (See
-   [e2e-nightly-main.yml][e2e] for an example.)
-
-2. Add a new section to the Mergify config (`.github/mergify.yml`) to enable the
-   backport bot to work on this branch, and add a corresponding `S:backport-to-v0.38.x`
-   [label](https://github.com/tendermint/tendermint/labels) so the bot can be triggered.
-
-3. Add a new section to the Dependabot config (`.github/dependabot.yml`) to
-   enable automatic update of Go dependencies on this branch. Copy and edit one
-   of the existing branch configurations to set the correct `target-branch`.

-
-## Pre-releases
-
-Before creating an official release, especially a minor release, we may want to
-create an alpha or beta version, or release candidate (RC) for our friends and
-partners to test out. We use git tags to create pre-releases, and we build them
-off of backport branches, for example:
-
-- `v0.38.0-alpha.1` - The first alpha release of `v0.38.0`. Subsequent alpha
-  releases will be numbered `v0.38.0-alpha.2`, `v0.38.0-alpha.3`, etc.
-
-  Alpha releases are to be considered the _most_ unstable of pre-releases, and
-  are most likely not yet properly QA'd. These are made available to allow early
-  adopters to start integrating and testing new functionality before we're done
-  with QA.
-
-- `v0.38.0-beta.1` - The first beta release of `v0.38.0`. Subsequent beta
-  releases will be numbered `v0.38.0-beta.2`, `v0.38.0-beta.3`, etc.
-
-  Beta releases can be considered more stable than alpha releases in that we
-  will have QA'd them better than alpha releases, but there still may be
-  minor breaking API changes if users have strong demands for such changes.
-
-- `v0.38.0-rc1` - The first release candidate (RC) of `v0.38.0`. Subsequent RCs
-  will be numbered `v0.38.0-rc2`, `v0.38.0-rc3`, etc.
-
-  RCs are considered more stable than beta releases in that we will have
-  completed our QA on them. APIs will most likely be stable at this point. The
-  difference between an RC and a release is that there may still be small
-  changes (bug fixes, features) that may make their way into the series before
-  cutting a final release.
-
-(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 pre-release for a minor release, you'll have to make a new
-backport branch (see above). Otherwise:
-
-1. Start from the backport branch (e.g. `v0.38.x`).
-2. 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-37x.yml).
-3. Prepare the pre-release documentation:
-   - Ensure that all relevant changes are in the `CHANGELOG_PENDING.md` file.
-     This file's contents must only be included in the `CHANGELOG.md` when we
-     cut final releases.
-   - Ensure that `UPGRADING.md` is up-to-date and includes notes on any breaking changes
-      or other upgrading flows.
-4. Prepare the versioning:
-   - Bump TMVersionDefault version in  `version.go`
-   - Bump P2P and block protocol versions in  `version.go`, if necessary.
-     Check the changelog for breaking changes in these components.
-   - Bump ABCI protocol version in `version.go`, if necessary
-5. Open a PR with these changes against the backport branch.
-6. Once these changes have landed on the backport branch, be sure to pull them back down locally.
-7. Once you have the changes locally, create the new tag, specifying a name and a tag "message":
-   `git tag -a v0.38.0-rc1 -m "Release Candidate v0.38.0-rc1`
-8. Push the tag back up to origin:
-   `git push origin v0.38.0-rc1`
-   Now the tag should be available on the repo's releases page.
-9. Future pre-releases will continue to be built off of this branch.
-
-## Minor release
-
-This minor release process assumes that this release was preceded by release
-candidates. If there were no release candidates, begin by creating a backport
-branch, as described above.
-
-Before performing these steps, be sure the
-[Minor Release Checklist](#minor-release-checklist) has been completed.
-
-1. Start on the backport branch (e.g. `v0.38.x`)
-2. Run integration tests (`make test_integrations`) and the e2e nightlies.
-3. Prepare the release:
-   - "Squash" changes from the changelog entries for the pre-releases 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-pre-release 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
-4. Open a PR with these changes against the backport branch.
-5. Once these changes are on the backport branch, push a tag with prepared release details.
-   This will trigger the actual release `v0.38.0`.
-   - `git tag -a v0.38.0 -m 'Release v0.38.0'`
-   - `git push origin v0.38.0`
-6. Make sure that `main` is updated with the latest `CHANGELOG.md`, `CHANGELOG_PENDING.md`, and `UPGRADING.md`.
-7. Add the release to the documentation site generator config (see
-   [DOCS\_README.md](./docs/DOCS_README.md) for more details). In summary:
-   - Start on branch `main`.
-   - Add a new line at the bottom of [`docs/versions`](./docs/versions) to
-     ensure the newest release is the default for the landing page.
-   - Add a new entry to `themeConfig.versions` in
-     [`docs/.vuepress/config.js`](./docs/.vuepress/config.js) to include the
-	 release in the dropdown versions menu.
-   - Commit these changes to `main` and backport them into the backport
-     branch for this release.
-
-## Patch release
-
-Patch releases are done differently from minor releases: They are built off of
-long-lived backport branches, rather than from main.  As non-breaking changes
-land on `main`, they should also be backported into these backport branches.
-
-Patch releases don't have release candidates by default, although any tricky
-changes may merit a release candidate.
-
-To create a patch release:
-
-1. Checkout the long-lived backport branch: `git checkout v0.38.x`
-2. Run integration tests (`make test_integrations`) and the nightlies.
-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 TMDefaultVersion in `version.go`
-   - Bump the ABCI version number, if necessary.
-     (Note that ABCI follows semver, and that ABCI versions are the only versions
-     which can change during patch releases, and only field additions are valid patch changes.)
-4. Open a PR with these changes that will land them back on `v0.38.x`
-5. Once this change has landed on the backport branch, make sure to pull it locally, then push a tag.
-   - `git tag -a v0.38.1 -m 'Release v0.38.1'`
-   - `git push origin v0.38.1`
-6. Create a pull request back to main with the CHANGELOG & version changes from the latest release.
-   - Remove all `R:patch` labels from the pull requests that were included in the release.
-   - Do not merge the backport branch into main.
-
-## Minor Release Checklist
-
-The following set of steps are performed on all releases that increment the
-_minor_ version, e.g. v0.25 to v0.26. These steps ensure that Tendermint is well
-tested, stable, and suitable for adoption by the various diverse projects that
-rely on Tendermint.
-
-### Feature Freeze
-
-Ahead of any minor version release of Tendermint, the software enters 'Feature
-Freeze' for at least two weeks. A feature freeze means that _no_ new features
-are added to the code being prepared for release. No code changes should be made
-to the code being released that do not directly improve pressing issues of code
-quality. The following must not be merged during a feature freeze:
-
-* Refactors that are not related to specific bug fixes.
-* Dependency upgrades.
-* New test code that does not test a discovered regression.
-* New features of any kind.
-* Documentation or spec improvements that are not related to the newly developed
-  code.
-
-This period directly follows the creation of the [backport
-branch](#creating-a-backport-branch). The Tendermint team instead directs all
-attention to ensuring that the existing code is stable and reliable. Broken
-tests are fixed, flakey-tests are remedied, end-to-end test failures are
-thoroughly diagnosed and all efforts of the team are aimed at improving the
-quality of the code. During this period, the upgrade harness tests are run
-repeatedly and a variety of in-house testnets are run to ensure Tendermint
-functions at the scale it will be used by application developers and node
-operators.
-
-### Nightly End-To-End Tests
-
-The Tendermint team maintains [a set of end-to-end
-tests](https://github.com/tendermint/tendermint/blob/main/test/e2e/README.md#L1)
-that run each night on the latest commit of the project and on the code in the
-tip of each supported backport branch. These tests start a network of
-containerized Tendermint processes and run automated checks that the network
-functions as expected in both stable and unstable conditions. During the feature
-freeze, these tests are run nightly and must pass consistently for a release of
-Tendermint to be considered stable.
-
-### Upgrade Harness
-
-> TODO(williambanfield): Change to past tense and clarify this section once
-> upgrade harness is complete.
-
-The Tendermint team is creating an upgrade test harness to exercise the workflow
-of stopping an instance of Tendermint running one version of the software and
-starting up the same application running the next version. To support upgrade
-testing, we will add the ability to terminate the Tendermint process at specific
-pre-defined points in its execution so that we can verify upgrades work in a
-representative sample of stop conditions.
-
-### Large Scale Testnets
-
-The Tendermint end-to-end tests run a small network (~10s of nodes) to exercise
-basic consensus interactions. Real world deployments of Tendermint often have
-over a hundred nodes just in the validator set, with many others acting as full
-nodes and sentry nodes. To gain more assurance before a release, we will also
-run larger-scale test networks to shake out emergent behaviors at scale.
-
-Large-scale test networks are run on a set of virtual machines (VMs). Each VM is
-equipped with 4 Gigabytes of RAM and 2 CPU cores. The network runs a very simple
-key-value store application. The application adds artificial delays to different
-ABCI calls to simulate a slow application. Each testnet is briefly run with no
-load being generated to collect a baseline performance. Once baseline is
-captured, a consistent load is applied across the network. This load takes the
-form of 10% of the running nodes all receiving a consistent stream of two
-hundred transactions per minute each.
-
-During each test net, the following metrics are monitored and collected on each
-node:
-
-* Consensus rounds per height
-* Maximum connected peers, Minimum connected peers, Rate of change of peer connections
-* Memory resident set size
-* CPU utilization
-* Blocks produced per minute
-* Seconds for each step of consensus (Propose, Prevote, Precommit, Commit)
-* Latency to receive block proposals
-
-For these tests we intentionally target low-powered host machines (with low core
-counts and limited memory) to ensure we observe similar kinds of resource contention
-and limitation that real-world  deployments of Tendermint experience in production.
-
-#### 200 Node Testnet
-
-To test the stability and performance of Tendermint in a real world scenario,
-a 200 node test network is run. The network comprises 5 seed nodes, 100
-validators and 95 non-validating full nodes. All nodes begin by dialing
-a subset of the seed nodes to discover peers. The network is run for several
-days, with metrics being collected continuously. In cases of changes to performance
-critical systems, testnets of larger sizes should be considered.
-
-#### Rotating Node Testnet
-
-Real-world deployments of Tendermint frequently see new nodes arrive and old
-nodes exit the network. The rotating node testnet ensures that Tendermint is
-able to handle this reliably. In this test, a network with 10 validators and
-3 seed nodes is started. A rolling set of 25 full nodes are started and each
-connects to the network by dialing one of the seed nodes. Once the node is able
-to blocksync to the head of the chain and begins producing blocks using
-Tendermint consensus it is stopped. Once stopped, a new node is started and
-takes its place. This network is run for several days.
-
-#### Network Partition Testnet
-
-Tendermint is expected to recover from network partitions. A partition where no
-subset of the nodes is left with the super-majority of the stake is expected to
-stop making blocks. Upon alleviation of the partition, the network is expected
-to once again become fully connected and capable of producing blocks. The
-network partition testnet ensures that Tendermint is able to handle this
-reliably at scale. In this test, a network with 100 validators and 95 full
-nodes is started. All validators have equal stake. Once the network is
-producing blocks, a set of firewall rules is deployed to create a partitioned
-network with 50% of the stake on one side and 50% on the other. Once the
-network stops producing blocks, the firewall rules are removed and the nodes
-are monitored to ensure they reconnect and that the network again begins
-producing blocks.
-
-#### Absent Stake Testnet
-
-Tendermint networks often run with _some_ portion of the voting power offline.
-The absent stake testnet ensures that large networks are able to handle this
-reliably. A set of 150 validator nodes and three seed nodes is started. The set
-of 150 validators is configured to only possess a cumulative stake of 67% of
-the total stake. The remaining 33% of the stake is configured to belong to
-a validator that is never actually run in the test network. The network is run
-for multiple days, ensuring that it is able to produce blocks without issue.

 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][tmsec-mailing].
-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.

 # Upgrading Tendermint Core
 
-This guide provides instructions for upgrading to specific versions of
-Tendermint Core.
-
-## Unreleased
-
-## Config Changes
-
-* A new config field, `BootstrapPeers` has been introduced as a means of
-  adding a list of addresses to the addressbook upon initializing a node. This is an
-  alternative to `PersistentPeers`. `PersistentPeers` shold be only used for
-  nodes that you want to keep a constant connection with i.e. sentry nodes
-
-----
-
-### ABCI Changes
-
-* The `ABCIVersion` is now `1.0.0`.
-
-* Added new ABCI methods `PrepareProposal` and `ProcessProposal`. For details,
-  please see the [spec](spec/abci/README.md). Applications upgrading to
-  v0.37.0 must implement these methods, at the very minimum, as described
-  [here](./spec/abci/abci++_app_requirements.md)
-* Deduplicated `ConsensusParams` and `BlockParams`.
-  In the v0.34 branch they are defined both in `abci/types.proto` and `types/params.proto`.
-  The definitions in `abci/types.proto` have been removed.
-  In-process applications should make sure they are not using the deleted
-  version of those structures.
-* In v0.34, messages on the wire used to be length-delimited with `int64` varint
-  values, which was inconsistent with the `uint64` varint length delimiters used
-  in the P2P layer. Both now consistently use `uint64` varint length delimiters.
-* Added `AbciVersion` to `RequestInfo`.
-  Applications should check that Tendermint's ABCI version matches the one they expect
-  in order to ensure compatibility.
-* The `SetOption` method has been removed from the ABCI `Client` interface.
-  The corresponding Protobuf types have been deprecated.
-* The `key` and `value` fields in the `EventAttribute` type have been changed
-  from type `bytes` to `string`. As per the [Protocol Buffers updating
-  guidelines](https://developers.google.com/protocol-buffers/docs/proto3#updating),
-  this should have no effect on the wire-level encoding for UTF8-encoded
-  strings.
-
-## v0.34.24
-
-Note that in [\#9724](https://github.com/tendermint/tendermint/pull/9724) we
-un-prettified the JSON output (i.e. removed all indentation) of the HTTP and
-WebSocket RPC for performance and subscription stability reasons. We recommend
-using a tool such as [jq](https://github.com/stedolan/jq) to obtain prettified
-output if you rely on that prettified output in some way.
-
-## v0.34.20
-
-### Feature: Priority Mempool
-
-This release backports an implementation of the Priority Mempool from the v0.35
-branch. This implementation of the mempool permits the application to set a
-priority on each transaction during CheckTx, and during block selection the
-highest-priority transactions are chosen (subject to the constraints on size
-and gas cost).
-
-Operators can enable the priority mempool by setting `mempool.version` to
-`"v1"` in the `config.toml`. For more technical details about the priority
-mempool, see [ADR 067: Mempool
-Refactor](https://github.com/tendermint/tendermint/blob/main/docs/architecture/adr-067-mempool-refactor.md).
