- TODO: Rewrite [client balancer](TODO) with [new gRPC balancer interface](TODO).

- Add [jitter to watch progress notify](https://github.com/coreos/etcd/pull/9278) to prevent [spikes in `etcd_network_client_grpc_sent_bytes_total`](https://github.com/coreos/etcd/issues/9246).

+- Improve [slow requests warning logging](https://github.com/coreos/etcd/pull/9288).

- e.g. `etcdserver: read-only range request "key:\"\\000\" range_end:\"\\000\" " took too long [3.389041388s] to execute`

+- Improve [TLS setup error logging](https://github.com/coreos/etcd/pull/9518) for [better debugging experience](https://github.com/coreos/etcd/issues/9400).

- Improve [long-running concurrent read transactions under light write workloads](https://github.com/coreos/etcd/pull/9296).
|
|
|
- Previously, periodic commit on pending writes blocks incoming read transactions, even if there is no pending write.
|
|
|
- Now, periodic commit operation does not block concurrent read transactions, thus improves long-running read transaction performance.
