 ### etcd server
 
+- Add [`rpctypes.ErrLeaderChanged`](https://github.com/etcd-io/etcd/pull/10094).
+  - Now linearizable requests with read index would fail fast when there is a leadership change, instead of waiting until context timeout.
 - Add [`etcd --initial-election-tick-advance`](https://github.com/etcd-io/etcd/pull/9591) flag to configure initial election tick fast-forward.
   - By default, `etcd --initial-election-tick-advance=true`, then local member fast-forwards election ticks to speed up "initial" leader election trigger.
   - This benefits the case of larger election ticks. For instance, cross datacenter deployment may require longer election timeout of 10-second. If true, local node does not need wait up to 10-second. Instead, forwards its election ticks to 8-second, and have only 2-second left before leader election.

+- Optimize [message send flow control](https://github.com/etcd-io/etcd/pull/9985).
+  - Leader now sends more append entries if it has more non-empty entries to send after updating flow control information.
+  - Now, Raft allows multiple in-flight append messages.
