+### Improvements
+
+- We introduced a new log node named `SystemTask` for logging system management actions.
+- We improved the performance of runtime statistics collection.
+- We improved the scheduling of cluster node management actions.
+- We added batching to the `session keep-alive` and `last action execution update` maintenance tasks. The batch size can be changed using the `SessionKeepAliveUpdateBatchSize` and `LastActionExecutionUpdateBatchSize` runtime settings.
+- We now remove web service user sessions if they are expired.
+- We now cleanup expired sessions in batches instead of all at once.
+
+### Fixes
+
+- We fixed an issue where trying to delete a huge number (millions) of anonymous sessions during startup would cause out of memory errors. We now delete sessions and anonymous users in batches to avoid this problem. (Ticket 257047)
+- We now avoid resetting failed login count during login when it is already zero. (Ticket 260858)
+- We fixed the issue that invalid sessions without an associated user were never removed from the database.
