+# Percona Distribution for MySQL 8.0.44 using Percona XtraDB Cluster (2025-12-10)
+
+Percona Distribution for MySQL is more than just a version of MySQL; it is a comprehensive solution that combines Percona Server for MySQL with additional tools to create a cohesive environment. This distribution is reliable, scalable, and secure, ensuring that all components have been tested to work seamlessly together. You can choose from two download options: one that uses Percona Server for MySQL and another that utilizes Percona XtraDB Cluster. Refer to [Install Percona Distribution for MySQL](installing.md).
+
+This release is focused on the Percona XtraDB Cluster-based deployment variation. It is based on [Percona XtraDB Cluster 8.0.44-35](https://docs.percona.com/percona-xtradb-cluster/8.0/release-notes/8.0.44-35.html).
+
+## Release highlights
+
+Announcement – Discontinuation of the Percona PRO Program
+
+Percona has consolidated its build offerings. The Pro builds are no longer required, and all features have been merged into the main open source Community release.
+
+### MySQL 8.0.44
+
+Improvements and bug fixes provided by Oracle for MySQL 8.0.44 and included in Percona Server for MySQL are the following:
+
+* Fixed an issue that caused excessive memory chunk usage for very large buffer pools, which could lead to allocation failures. The allocation process now includes validation to ensure sufficient and stable memory allocation. (Bug #37994397)
+
+* Fixed an issue where assertion failures could occur due to data size and bounds mismatches during DDL file operations. (Bug #37882398)
+
+Find the complete list of bug fixes and changes in the [MySQL 8.0.44 Release Notes](https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-44.html).
