     * [x/stake] Improve speed of GetValidator, which was shown to be a performance bottleneck. [#2046](https://github.com/tendermint/tendermint/pull/2200)
     * [genesis] \#2229 Ensure that there are no duplicate accounts or validators in the genesis state.
     * Add SDK validation to `config.toml` (namely disabling `create_empty_blocks`) \#1571
+    * \#1941(https://github.com/cosmos/cosmos-sdk/issues/1941) Version is now inferred via `git describe --tags`.
 
 * SDK
     * [tools] Make get_vendor_deps deletes `.vendor-new` directories, in case scratch files are present.
