+
+* [PS-11161](https://perconadev.atlassian.net/browse/PS-11161): Performance optimizations for `mem_root_deque`.

+* [PS-10083](https://perconadev.atlassian.net/browse/PS-10083): Enhanced Thread Pool Statistics.
+
+* [PS-10989](https://perconadev.atlassian.net/browse/PS-10989): Added JSONL (JSON Lines) output format for Audit Log Filter.

+
+* [PS-10070](https://perconadev.atlassian.net/browse/PS-10070): Updated the existing component to use the new KMIP library.
+
+* [PS-10083](https://perconadev.atlassian.net/browse/PS-10083): Enhanced Thread Pool Statistics.


Probably

Enhances Thread Pool statistics by adding new status variables for queue monitoring and wait time analysis. The new metrics report the number of requests waiting in normal and high-priority queues, the number of requests not yet entered into a queue, and aggregate queue wait time statistics, including average, minimum, maximum, and standard deviation wait times. These additions provide greater visibility into thread pool workload and queueing behavior.

+
+* [PS-9773](https://perconadev.atlassian.net/browse/PS-9773): The Audit Log Filter `audit_log_read()` function always showed `"null"` instead of the bookmarked and current information.
+
+* [PS-9791](https://perconadev.atlassian.net/browse/PS-9791): The audit log format was incorrect.


The audit_log_filter component generated audit records that did not include complete user, host, and query information in a single event, making the logs difficult to analyze and process.

 # Percona Server for MySQL {{vers}} release notes index

-* 


This additional info occupies the whole page, and the main purpose of the release index is to list the releases. We have a standard across all projects: listing only the release notes. I think this page is self-explanatory and requires no additional explanations or descriptions.
