+# Percona XtraDB Cluster 8.0.38
+
+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 XtraDB Cluster 8.0.39-30 (2024-12-02)
+
+[Get started with Quickstart Guide for Percona XtraDB Cluster.](../quickstart-overview.md)
+
+Percona XtraDB Cluster 8.0.39-30 includes all the features and bug fixes available in Percona Server for MySQL 8.0.39-29. [Percona Server for MySQL 8.0.38](https://docs.percona.com/percona-server/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](../telemetry.md) document.
+
+Improvements and bug fixes provided by Oracle for  MySQL 8.0.38 and MySQL 8.0.39 and included in Percona Server for MySQL 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).
+
+## Bug fixes
+
+* [PXC-4452](https://perconadev.atlassian.net/browse/PXC-4452): The `slow_query_log_file` has a default value if applied in conjunction with `max_slowlog_size`.
+
+* [PXC-4495](https://perconadev.atlassian.net/browse/PXC-4495): A Percona XtraDB Cluster node suddenly began accumulating on-demand cache files. The cache pool grows until the disk is full.
+
+* [PXC-4500](https://perconadev.atlassian.net/browse/PXC-4500): A Percona XtraDB Cluster enters a broken state after a failed node restart.
+
+* [PXC-4521](https://perconadev.atlassian.net/browse/PXC-4521): Percona Telemetry creates a dedicated, internal user limited to only collecting metrics. The user is created automatically when Percona Telemetry is enabled. If Percona Telemetry is disabled, the user is dropped during server startup.
