 # Changelog
 
+## v0.26.0
+
+*October 31, 2018*
+
+Special thanks to external contributors on this release:
+@bradyjoestar, @connorwstein, @goolAdapter, @HaoyangLiu,
+@james-ray, @overbool, @phymbert, @Slamper, @Uzair1995, @yutianwu
+
+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.
+
+Please note that we are still making breaking changes to the protocols.
+While the new Version fields should help us to keep the software backwards compatible
+even while upgrading the protocols, we cannot guarantee that new releases will
+be compatible with old chains just yet. Thanks for bearing with us!
+
+Friendly reminder, we have a [bug bounty program](https://hackerone.com/tendermint).
