 * (x/staking) [#15701](https://github.com/cosmos/cosmos-sdk/pull/15701) `HistoricalInfoKey` now has a binary format.
 * (grpc-web) [#14652](https://github.com/cosmos/cosmos-sdk/pull/14652) Use same port for gRPC-Web and the API server.
+* (abci) [#15845](https://github.com/cosmos/cosmos-sdk/pull/15845) Add `msg_index` to all event attributes to associate events and messages
+* (abci) [#15845](https://github.com/cosmos/cosmos-sdk/pull/15845) Remove duplicating events in `logs`

+#### Events
+
+The log section of abci.TxResult is not populated in the case of successful msg(s) execution. Instead a new attribute is added to all messages indicating the `msg_index` which identifies which events and attributes relate the same transaction
+
 #### gRPC-Web
 
 gRPC-Web is now listening to the same address as the gRPC Gateway API server (default: `localhost:1317`).

 * A `type` to categorize the Event at a high-level; for example, the Cosmos SDK uses the `"message"` type to filter Events by `Msg`s.
 * A list of `attributes` are key-value pairs that give more information about the categorized Event. For example, for the `"message"` type, we can filter Events by key-value pairs using `message.action={some_action}`, `message.module={some_module}` or `message.sender={some_sender}`.

 To parse the attribute values as strings, make sure to add `'` (single quotes) around each attribute value.
