+# v5.1.5
+
+## Enhancements
+
+- [#10697](https://github.com/emqx/emqx/pull/10697) This change allows to set the minReadySeconds for the StatefulSet. This allows to add a gap between the restarts of each pod by upgrade or restart command.
+
+- [#11390](https://github.com/emqx/emqx/pull/11390) Add `node.broker_pool_size`, `node.generic_pool_size`, `node.channel_cleanup_batch_size` options to EMQX configuration.
+
+  Tuning these options can significantly improve performance if cluster interconnect network latency is high.
+
+- [#11389](https://github.com/emqx/emqx/pull/11389) Improved retained message publishing latency by consolidating multiple index update operations into a single mnesia activity, leveraging the new APIs introduced in mria 0.6.0.
+
+## Bug Fixes
+
+- [#11388](https://github.com/emqx/emqx/pull/11388) Increase `emqx_router_sup` restart intensity.
+
+  The goal is to tolerate occasional crashes that can happen under relatively normal conditions
+  and don't seem critical to shutdown the whole app (emqx).
+  For example, mria write/delete call delegated from a replicant to a core node by `emqx_router_helper` may fail,
+  if the core node is being stopped / restarted / not ready.
+
+- [#11410](https://github.com/emqx/emqx/pull/11410) Reintroduce `cacerts` TLS client option as a deprecated option.
+
+  This fixes issues found when trying to upgrade from 5.1.3 where that option is set in the configuration files or persisted in EMQX Operator settings.
