| 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). | Friendly reminder, we have a [bug bounty program](https://hackerone.com/tendermint). | ||||
