 # 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

 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`.
