 * Add per-IP throttling of failed attempts on the admin password login endpoint (`POST /admin/auth`) to slow down brute-force. A valid login is not affected, even while an attack is in progress. This is best-effort protection only – the admin endpoint should still be protected at the infrastructure level (firewall rules, private network, authenticating reverse proxy) ([#1204](https://github.com/centrifugal/centrifugo/pull/1204), commit [`7f8e8f6b`](https://github.com/centrifugal/centrifugo/commit/7f8e8f6b)).
 * Harden the binary (Protobuf) protocol frame decoder so that a crafted length prefix can no longer make the server allocate too much memory. The configured message size limit is now always applied when reading client commands ([#1203](https://github.com/centrifugal/centrifugo/pull/1203), commit [`558c7dda`](https://github.com/centrifugal/centrifugo/commit/558c7dda), and [centrifugal/centrifuge#612](https://github.com/centrifugal/centrifuge/pull/612)).
 * Redis Sentinel: the Sentinel client now periodically refreshes its topology, so changes such as a new master after a failover are picked up more reliably ([#1201](https://github.com/centrifugal/centrifugo/pull/1201), commit [`9015e98d`](https://github.com/centrifugal/centrifugo/commit/9015e98d), and [centrifugal/centrifuge#611](https://github.com/centrifugal/centrifuge/pull/611)).
+* Redis Sentinel: Centrifugo also inherited several important Redis Sentinel setup stability improvements from the updated `rueidis` client ([v1.0.77 release notes](https://github.com/redis/rueidis/releases/tag/v1.0.77)).
