 ### Enhancements
 
-- Configure `cnm_http_workers` and `cnm_http_max_threads_per_worker` using a [`PUT /v1/cluster`]({{<relref "/operate/rs/references/rest-api/requests/cluster#put-cluster">}}) REST API request.
+- Allow configuring `cnm_http_workers` and `cnm_http_max_threads_per_worker` using a [`PUT /v1/cluster`]({{<relref "/operate/rs/references/rest-api/requests/cluster#put-cluster">}}) REST API request. You can update these settings if the API load is higher than the cluster can handle by default. Configuring more workers than the default will consume more memory.
 
-- Improved Cluster Configuration Store (CCS) CPU usage
+- Reduced CCS CPU usage, following the addition of the internal caching mechanism in the resource management calculations.

 ### Resolved issues
 
-- RS122221: `redis-server` creates PID file only after binding to a socket.
-
 - RS123237: CRDT syncer prevents potential data mismatches or data loss due to missing keys when removing and re-adding a cluster in an Active-Active setup with at least three participating clusters after removing older clusters without re-adding them.
 
-- RS93876: Optimized resharding order.
+- RS93876: When resharding is performed with `shards_blueprint`, improved the order of resharding to avoid stuck state machines due to low memory.
 
 - RS119350: Avoid removing roles bound to LDAP mappings during cluster upgrade even if the roles aren't assigned to any users.
 
-- RS123561: Enclosed `$PORT_DNS` with double quotes so the variable is expanded when the install script checks if the port is free.
+- RS123561: Better identification for the occupied DNS port to ensure successful installation.
 
-- RS122365: Improved platform and module readiness checks. A module is ready if all platforms in the cluster are ready.
+- RS122365: Improved platform and module readiness checks so they ignore operating systems that are no longer part of the cluster.
 
 - RS96400: DMC management threads properly terminate instead of maintaining a blocking connection if they can't reach the CCS after a predefined time.

+- RS110798: Made several improvements to reduce `cluster_wd` request latency, fixing communication errors on large clusters.
 
-- RS119705: Upgrade CCS schema before restarting services to prevent possible DMC downtime.
+- RS119705: On in-place upgrades, minimize DMC downtime by performing CCS schema upgrade before services are restarted.
