 - Fix [server panic on invalid Election Proclaim/Resign HTTP(S) requests](https://github.com/coreos/etcd/pull/9379).
   - Previously, wrong-formatted HTTP requests to Election API could trigger panic in etcd server.
   - e.g. `curl -L http://localhost:2379/v3/election/proclaim -X POST -d '{"value":""}'`, `curl -L http://localhost:2379/v3/election/resign -X POST -d '{"value":""}'`.
+- Prevent [overflow by large `TTL` values for `Lease` `Grant`](https://github.com/coreos/etcd/pull/9399).
+  - `TTL` parameter to `Grant` request is unit of second.
+  - Leases with too large `TTL` values exceeding `math.MaxInt64` [expire in unexpected ways](https://github.com/coreos/etcd/issues/9374).
+  - Server now returns `rpctypes.ErrLeaseTTLTooLarge` to client, when the requested `TTL` is larger than 9,000,000,000 (which is >285 years).
+  - Again, etcd `Lease` is meant for short-periodic keepalives or sessions, in the range of seconds or minutes. Not for hours or days!
 - Enable etcd server [`raft.Config.CheckQuorum` when starting with `ForceNewCluster`](https://github.com/coreos/etcd/pull/9347).
