   * [\#2019](https://github.com/cosmos/cosmos-sdk/issues/2019) Cap total number of signatures. Current per-transaction limit is 7, and if that is exceeded transaction is rejected.
   * [\#2801](https://github.com/cosmos/cosmos-sdk/pull/2801) Remove AppInit structure.
   * [\#2798](https://github.com/cosmos/cosmos-sdk/issues/2798) Governance API has miss-spelled English word in JSON response ('depositer' -> 'depositor')
+  * [\#2943](https://github.com/cosmos/cosmos-sdk/pull/2943) Transaction action tags equal the message type. Stake EndBlocker tags are included.
