+# Percona XtraDB Cluster 8.4.5-5 (2025-06-)
+
+Percona XtraDB Cluster (PXC) supports critical business applications in both cloud and on-premises environments, including public, private, and hybrid setups. Our free, open source, enterprise-grade solution includes the high availability and security features your business requires to meet your customer expectations and business goals.
+
+## Release highlights
+
+Percona XtraDB Cluster 8.4.5-5 is based on Percona Server for MySQL and includes all improvements and bug fixes available in the [Percona Server for MySQL 8.4.5-5 (2025-05-29) release notes](https://docs.percona.com/percona-server/8.4/release-notes/8.4.5-5.html).
+
+### Percona XtraDB Cluster 8.4.5-5
+
+Improves State Snapshot Transfer (SST) failure diagnostics. `garbd` now uses distinct exit codes to differentiate between donor exit, SST script failure, and garbd-initiated termination, making SST issues easier to identify and debug.
+
+### Percona Server for MySQL 8.4.5-5
+
+* Updates the C++ level of the KMPI library to enhance error handling capabilities.
+
+* Improves optimizer behavior by restoring correct handling of const tables in `test_quick_select()`. A MySQL Upstream refactor (commit [9a13c1c](https://github.com/percona/percona-server/commit/9a13c1c6971f4bd56d143179ecfb34cca8ecc018)) removed the `QEP_TAB` dependency, causing `get_quick_record_count()` to no longer pass const table information. This could lead to suboptimal range scan boundaries. The applied patch resolves the issue by explicitly passing `const_tables` to `test_quick_select()`, ensuring consistent behavior with the pre-refactor logic.
+
+The latest MyRocks storage engine incorporates code based on RocksDB version 9.3.1. Percona has applied minor modifications to the original RocksDB codebase. Check the list of modifications at [https://github.com/percona/rocksdb/](https://github.com/percona/rocksdb/commit/2864cd95ca72bc4a2e93fe461dbd980f8e2357be).

+
+Improvements and bug fixes introduced by Oracle for MySQL 8.4.5 and included in Percona Server for MySQL are the following:

+
+* Fixed an issue in InnoDB redo log recovery to improve data safety after a crash. (Bug #37061960)
+
+* Fixed an issue where reading `index_id` values could lead to incorrect behavior with indexes. (Bug #36993445, Bug #37709706)
+
+* Fixed a bug related to the `lower_case_table_names` setting that caused inconsistent behavior with table names on different systems. (Bug #32288105)
+
+* Fixed a bug where `mysqldump` did not properly escape certain special characters in its output. (Bug #37540722, Bug #37709163)
+
+* The `fprintf_string()` function in `mysqldump` did not use the correct quote character for escaping strings. (Bug #37607195)
+
+Find the complete list of bug fixes and changes in the [MySQL 8.4.5 release notes](https://dev.mysql.com/doc/relnotes/mysql/8.4/en/news-8-4-5.html).
+
+## Improvements
+
+[PXC-4645](https://perconadev.atlassian.net/browse/PXC-4645): Improves State Snapshot Transfer (SST) failure diagnostics. `garbd` now uses distinct exit codes to differentiate between donor exit, SST script failure, and garbd-initiated termination, making SST issues easier to identify and debug.
+
+## Bug fixes
+
+* [PXC-3576](https://perconadev.atlassian.net/browse/PXC-3576): Percona XtraDB Cluster created role mappings using an upper-case database name when `lower_case_table_names=1` was set.
+
+* [PXC-4394](https://perconadev.atlassian.net/browse/PXC-4394): Improved error reporting for scenarios where Percona Xtrabackup, used during State Snapshot Transfer (SST), failed to report its version. These failures may be caused by missing libraries or a broken installation.
+
+* [PXC-4399](https://perconadev.atlassian.net/browse/PXC-4399): Executing `FLUSH TABLES` on a table while writes were in progress caused the cluster node to stall.
+
+* [PXC-4512](https://perconadev.atlassian.net/browse/PXC-4512): When `RENAME TABLE` was executed on a child table concurrently with `INSERT`/`UPDATE` on a parent table, a Metadata Lock (MDL) BF-BF conflict occured on the replica, causing two cluster nodes to enter NON-PRIMARY state.
+
+* [PXC-4629](https://perconadev.atlassian.net/browse/PXC-4629): Creating a temporary table with `CREATE TEMPORARY TABLE ... AS SELECT` put the entire session into Transaction Ordered Index (TOI ) / Next Binary Operation (NBO) lock state, preventing any queries from being killed within that session.
+
+* [PXC-4638](https://perconadev.atlassian.net/browse/PXC-4638): After performing State Snapshot Transfer (SST), the `binlog.index` file contents became inconsistent, causing the `binlog_utils_udf` plugin to fail when accessing the binlog file. Was fixed within [PS-9777](https://perconadev.atlassian.net/browse/PS-9777).
+
+* [PXC-4652](https://perconadev.atlassian.net/browse/PXC-4652): Fixed a segmentation fault (SIGSEGV) on nodes with `wsrep_applier_threads > 1` under high write activity.
+
+* [PXC-4657](https://perconadev.atlassian.net/browse/PXC-4657): There was Metadata Lock (MDL) BF-BF conflict between two applier threads.
+
+* [PXC-4684](https://perconadev.atlassian.net/browse/PXC-4684): An `UPDATE` query that referenced two tables but only modified one could cause an Metadata Lock (MDL) BF-BF conflict on other cluster nodes.
+
+* [PXC-4664](https://perconadev.atlassian.net/browse/PXC-4664): Executing transactions with the same Global Transaction Identifier (GTID) on different nodes caused a node to exit.
+
+* [PXC-4688](https://perconadev.atlassian.net/browse/PXC-4688): A regression in asynchronous replication caused the replica thread to stall when processing empty transactions.
