 # Changelog
 
+## v0.31.5
+
+*April 16th, 2019*
+
+This release fixes a regression from v0.31.4 where, in existing chains that
+were upgraded, `/validators` could return an empty validator set. This is true
+for almost all heights, given the validator set remains the same.
+
+Special thanks to external contributors on this release:
+@brapse, @guagualvcha, @dongsam, @phucc
+
+### IMPROVEMENTS:
+
+- [libs/common] `CMap`: slight optimization in `Keys()` and `Values()` (@phucc)
+- [gitignore] gitignore: add .vendor-new (@dongsam)

+### BUG FIXES:

+- [state] [\#3537](https://github.com/tendermint/tendermint/pull/3537#issuecomment-482711833)
+  `LoadValidators`: do not return an empty validator set
+- [blockchain] [\#3457](https://github.com/tendermint/tendermint/issues/3457)
+  Fix "peer did not send us anything" in `fast_sync` mode when under high pressure

 It brings back `NetAddress()` to `NodeInfo` and uses it instead of `SocketAddr` for adding peers.
 Additionally, it improves response time on the `/validators` or `/status` RPC endpoints.
 As a side-effect it makes these RPC endpoint more difficult to DoS and fixes a performance degradation in `ExecCommitBlock`.

+
+Tendermint Core is Byzantine Fault Tolerant (BFT) middleware that takes a state transition machine - written in any programming language -
+and securely replicates it on many machines.
+
+For protocol details, see [the specification](/docs/spec).
+
+For detailed analysis of the consensus protocol, including safety and liveness proofs,
+see our recent paper, "[The latest gossip on BFT consensus](https://arxiv.org/abs/1807.04938)".
+
+## A Note on Production Readiness
+
+While Tendermint is being used in production in private, permissioned
+environments, we are still working actively to harden and audit it in preparation
+for use in public blockchains, such as the [Cosmos Network](https://cosmos.network/).
+We are also still making breaking changes to the protocol and the APIs.
+Thus, we tag the releases as *alpha software*.
+
+In any case, if you intend to run Tendermint in production,
+please [contact us](mailto:[email protected]) and [join the chat](https://riot.im/app/#/room/#tendermint:matrix.org).

+
+## 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
+
+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 in-process Go APIs.
+
+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
+- types
+- rpc/client
+- config
+- node
+- libs
+  - bech32
+  - common
+  - db
+  - errors
+  - log
+
+Exported objects in these packages that are not covered by the versioning scheme
+are explicitly marked by `// UNSTABLE` in their go doc comment and may change at any
+time without notice. Functions, types, and values in any other package may also change at any time.
+
+### 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 histories
+(if not please open an [issue](https://github.com/tendermint/tendermint/issues)).
+
+For more information on upgrading, see [UPGRADING.md](./UPGRADING.md)
