+# Percona XtraDB Cluster 8.0.41-32 (2025-03-13)
+
+[Get started with Quickstart Guide for Percona XtraDB Cluster.](../quickstart-overview.md)
+
+Percona XtraDB Cluster 8.0.41-32 includes all the features and bug fixes available in Percona Server for MySQL 8.0.41-32.
+
+## 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 8.0.41-32 (2025-02-26) release notes](https://docs.percona.com/percona-server/8.0/release-notes/8.0.41-32.html).
+
+### Percona XtraDB Cluster 8.0.41-32
+
+Implements the [Clone plugin for State Snapshot Transfer (SST) Method](https://docs.percona.com/percona-xtradb-cluster/8.0/clone-sst.html). The Clone SST is a modern and efficient method that leverages MySQL's native cloning capabilities to transfer data from a donor node to a Joiner node. It is faster and more resource-efficient compared to traditional methods like xtrabackup or rsync.
+
+### Percona Server for MySQL 8.0.41-32
+
+* Extends the [Encryption user-defined functions](https://docs.percona.com/percona-server/8.0/encryption-functions.html) with the following:
+
+     * Added support for `pkcs1`, `oaep`, or `no` padding for RSA encrypt and decrypt operations
+
+     * Added support for `pkcs1` or `pkcs1_pss` padding for RSA sign and verify operations
+
+     * Added the `encryption_udf.legacy_padding_scheme` system variable to manage legacy padding schemes
+
+     * Added the character set awareness
+
+* Improves the [Data masking](https://docs.percona.com/percona-server/8.0/data-masking-overview.html) performance by introducing an internal term cache. The new cache speeds up lookups for `gen_blocklist()` and `gen_dictionary()` functions by storing dictionary data in memory.
+
+    Find more detailed information in the [Data masking overview](https://docs.percona.com/percona-server/8.0/data-masking-overview.html) and in the [Data masking component functions](https://docs.percona.com/percona-server/8.0/data-masking-function-list.html).
+
+### MySQL 8.0.41
+
+Improvements and bug fixes provided by Oracle for MySQL 8.0.41 and included in Percona Server for MySQL are the following:
+
+* Fixed an assertion in debug builds where certain IO buffer serializations caused system hangs. (Bug #37139618)
+
+* Resolved a failure when dropping the primary key and adding a new `AUTO_INCREMENT` column as the primary key in descending order using the `INPLACE` algorithm resulted in failure. (Bug #36658450)
+
+* Fixed incorrect results, including missing rows, in queries that used a descending primary key with the `index_merge` optimization. (Bug #106207, Bug #33767814)
+
+* Addressed a replication channel issue where MySQL failed to stop the channel properly when large transactions were being processed, and `STOP REPLICA` was requested. This issue also prevented graceful server shutdown, requiring process termination or system restart. (Bug #115966, Bug #37008345)

+Find the complete list of bug fixes and changes in the [MySQL 8.0.41 Release Notes](https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-41.html).
+
+## Improvements
+
+[PXC-4469](https://perconadev.atlassian.net/browse/PXC-4469): Implements the [Clone plugin for State Snapshot Transfer (SST) Method](https://docs.percona.com/percona-xtradb-cluster/8.0/clone-sst.html).
+
+## Bug fixes
+
+* [PXC-4173](https://perconadev.atlassian.net/browse/PXC-4173): The Percona XtraDB Cluster node stalled when parallel replication workers executed DDLs through an asynchronous node.
+
+* [PXC-4390](https://perconadev.atlassian.net/browse/PXC-4390): The `wsrep_group_commit_queue` option was removed because caused deadlock bugs.
+
+* [PXC-4498](https://perconadev.atlassian.net/browse/PXC-4498): The Percona XtraDB Cluster node stalled and caused the cluster to stop responding.
+
+* [PXC-4393](https://perconadev.atlassian.net/browse/PXC-4393): On the donor side, if the pipeline had more than two commands, only the last command’s failure was detected, but the error was shown for the second-to-last command.
+
+* [PXC-4404](https://perconadev.atlassian.net/browse/PXC-4404): Setting the `wsrep_preordered=ON` option caused protocol violations.
+
+* [PXC-4504](https://perconadev.atlassian.net/browse/PXC-4504): The `DROP PROCEDURE/FUNCTION IF EXISTS` option generated a local Global Transaction Identifier (GTID) event.
+
+* [PXC-4506](https://perconadev.atlassian.net/browse/PXC-4506): The asynchronous replication threads on a Percona XtraDB Cluster node hung when resuming from an applier error after it was fixed.
+
+* [PXC-4509](https://perconadev.atlassian.net/browse/PXC-4509): The asynchronous replication hung on the Percona XtraDB Cluster node if the replica received Global Transaction Identifier (GTID) from the source that had already been committed on it.
+
+* [PXC-4515](https://perconadev.atlassian.net/browse/PXC-4515): Multi-source replication didn't work on the Percona XtraDB Cluster node with the new asynchronous monitor logic.
+
+* [PXC-4516](https://perconadev.atlassian.net/browse/PXC-4516): Global Transaction Identifier (GTID) auto-positioning replication didn't work correctly on the Percona XtraDB Cluster node with the new async monitor logic.
+
+* [PXC-4573](https://perconadev.atlassian.net/browse/PXC-4573): The `mysql.pxc.sst.role` lacked the `INNODB_REDO_LOG_ARCHIVE` privilege when the State Snapshot Transfer (SST) required InnoDB redo log archiving.
