 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`
+  - `/validators`, if `height` is supplied
+
+## 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.
+
+Special thanks to external contributors on this release: @rootwarp & @animart
+
+### FEATURES
+
+- [cli] [\#9083](https://github.com/tendermint/tendermint/issues/9083) Backport command to reindex missed events (@cmwaters)
+- [cli] [\#9107](https://github.com/tendermint/tendermint/issues/9107) Add the `p2p.external-address` argument to set the node P2P external address (@amimart)
+
+### IMPROVEMENTS
+
+- [config] [\#9054](https://github.com/tendermint/tendermint/issues/9054) `discard_abci_responses` flag added to discard all ABCI
+  responses except the last in order to save on storage space in the state
+  store (@samricotta)
+
+### BUG FIXES

 Before creating an official release, especially a minor 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.
+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:
 
-Tags for RCs should follow the "standard" release naming conventions, with
-`-rcX` at the end (for example, `v0.35.0-rc0`).
+* `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.)
