+# Percona Distribution for MySQL 8.0.38 using Percona XtraDB Cluster
+
+Due to a critical fix, MySQL Community Server 8.0.39 was released shortly (22 days later) after MySQL Community Server 8.0.38. Percona has skipped the release of Percona Server for MySQL 8.0.38 and Percona XtraDB Cluster 8.0.38. Percona XtraDB Cluster 8.0.39-30 is based on Percona Server for MySQL 8.0.39-30, which contains all bug fixes and contents from MySQL Community Server 8.0.38 and MySQL Community Server 8.0.39.

+# Percona Distribution for MySQL 8.0.39 using Percona XtraDB Cluster (2024-12-02)
+
+Percona Distribution for MySQL is the most stable, scalable and secure open-source MySQL distribution, with two download options: one based on Percona Server for MySQL and one based on Percona XtraDB Cluster. [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 8.0.39-30](https://docs.percona.com/percona-xtradb-cluster/8.0/release-notes/8.0.39-30.html). [Percona XtraDB Cluster 8.0.38](https://docs.percona.com/percona-xtradb-cluster/8.0/release-notes/8.0.38.html) was skipped.
+
+## Release highlights
+
+Percona XtraDB Cluster is based on Percona Server for MySQL. Find a complete list of improvements and bug fixes in the [Percona Server for MySQL 8.0.39-30 (2024-10-08) release notes](https://docs.percona.com/percona-server/8.0/release-notes/8.0.39-30.html).
+
+The release also installs Percona Telemetry. Find more information in the [Telemetry on Percona XtraDB Cluster](https://docs.percona.com/percona-xtradb-cluster/8.0/telemetry.html) document.
+
+Improvements and bug fixes provided by Oracle for  MySQL 8.0.38 and MySQL 8.0.39 and included in Percona XtraDB Cluster are the following:
+
+* The server could not restart successfully after creating a large number of tables (8001 or more). This issue, Bug #36808732, is a regression of Bug #33398681.
+
+* Enhanced performance of tablespace file scanning during startup. (Bug #110402, Bug #35200385)
+
+* InnoDB file system operations now consistently perform an fsync on the parent directory when carrying out directory-altering tasks. (Bug #36174938)
+
+* Worker jobs now include details about the relay log file that initiated the transaction, rather than relying on the default specified by `relay_log`.
+
+Find the complete list of bug fixes and changes in the [MySQL 8.0.38 Release Notes](https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-38.html) and [MySQL 8.0.39 Release Notes](https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-39.html).
