+## v0.26.0

 Special thanks to external contributors on this release:

+@james-ray, @overbool, @phymbert, @Slamper, @Uzair1995
+
+This release is primarily about adding Version fields to various data structures,
+optimizing consensus messages for signing and verification in
+restricted environments (like HSMs and the Ethereum Virtual Machine), and
+aligning the consensus code with the [specification](https://arxiv.org/abs/1807.04938).
+It also includes our first take at a generalized merkle proof system.
+
+See the [UPGRADING.md](UPGRADING.md#v0.26.0) for details on upgrading to the new
+version.
+
+Friendly reminder, we have a [bug bounty program](https://hackerone.com/tendermint).
 
 BREAKING CHANGES:
 
 * CLI/RPC/Config
   * [config] \#2232 timeouts as time.Duration, not ints
   * [config] \#2505 Remove Mempool.RecheckEmpty (it was effectively useless anyways)
   * [config] `mempool.wal` is disabled by default
-  * [rpc] \#2298 `/abci_query` takes `prove` argument instead of `trusted` and switches the default
-    behaviour to `prove=false`
   * [privval] \#2459 Split `SocketPVMsg`s implementations into Request and Response, where the Response may contain a error message (returned by the remote signer)
   * [state] \#2644 Add Version field to State, breaking the format of State as
     encoded on disk.
+  * [rpc] \#2298 `/abci_query` takes `prove` argument instead of `trusted` and switches the default
+    behaviour to `prove=false`
   * [rpc] \#2654 Remove all `node_info.other.*_version` fields in `/status` and
     `/net_info`
