# Percona Server for MySQL 8.0.42-33 (2025-05-19)
2+
3+
Get started with [Quickstart Guide for Percona Server for MySQL](../quickstart-overview.md).
4+
5+
[Percona Server for MySQL 8.0.42-33](https://www.percona.com/mysql/software) includes all the features and bug fixes available in the [MySQL 8.0.42 Community Edition](https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-42.html) and enterprise-grade features developed by Percona.
6+
7+
## Release highlights
8+
9+
### Percona Server for MySQL 8.0.42-33
10+
11+
* Improves the `audit_log_filter_set_user()` UDF to accept account names with wildcard characters (`'%'` and `'_'`) in the host part. For example, you can use `‘usr1@%'`, `‘usr2%192.168.0.%’`, or `'usr3@%.mycorp.com'`.
12+
13+
* Updates the C++ level of the KMPI library to enhance error handling capabilities.
14+
15+
* 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.
16+
17+
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).

### MySQL 8.0.42
60+
61+
Improvements and bug fixes provided by Oracle for MySQL 8.0.42 and included in Percona Server for MySQL are the following:
62+
63+
* Fixed an issue where `CHECK TABLE` sometimes incorrectly reported that spatial indexes were corrupted. (Bug #37286473)
64+
65+
* Fixed an issue in InnoDB redo log recovery to improve data safety after a crash. (Bug #37061960)
66+
67+
* Fixed an issue where reading `index_id` values could lead to incorrect behavior with indexes. (Bug #36993445, Bug #37709706)
68+
69+
* Fixed a bug related to the `lower_case_table_names` setting that caused inconsistent behavior with table names on different systems. (Bug #32288105)
70+
71+
* Fixed a bug where `mysqldump` did not properly escape certain special characters in its output. (Bug #37540722, Bug #37709163)
72+
73+
* The `fprintf_string()` function in `mysqldump` did not use the correct quote character for escaping strings. (Bug #37607195)
74+
75+
76+
Find the complete list of bug fixes and changes in the [MySQL 8.0.42 Release Notes](https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-42.html).
77+
78+
## Improvements
79+
80+
* [PS-9024](https://perconadev.atlassian.net/browse/PS-9024): Improves the `audit_log_filter_set_user()` UDF to accept account names with wildcard characters (`'%'` and `'_'`) in the host part.
81+
82+
* [PS-9561](https://perconadev.atlassian.net/browse/PS-9561): Updates the C++ level of the KMPI library to enhance error handling capabilities.
83+
84+
* [PS-9765](https://perconadev.atlassian.net/browse/PS-9765): Updates the list of MyRocks variables. You can find the list of variables in [MyRocks server variables](../variables.md).
85+
86+
## Bug Fixes
87+
88+
* [PS-9033](https://perconadev.atlassian.net/browse/PS-9033): The `audit_log_filter` plugin did not register remote accesses.
89+
90+
* [PS-9390](https://perconadev.atlassian.net/browse/PS-9390): In some cases, using `JSON_TABLE` inside an `IN` or `EXISTS` subquery caused incorrect results. This happened when the subquery referred to a table from the main query, and a semijoin optimization was applied. Percona merged the fix from [MySQL](https://github.com/mysql/mysql-server/commit/15e6812b80 ).
91+
92+
* [PS-9609](https://perconadev.atlassian.net/browse/PS-9609): The `audit_log_filter` plugin could not be installed when Percona Server was using `component_keyring_kmip`.
93+
94+
* [PS-9628](https://perconadev.atlassian.net/browse/PS-9628): The `binlog_encryption` did not work with `component_keyring_kmip`.
95+
96+
* [PS-9703](https://perconadev.atlassian.net/browse/PS-9703): In-place `ALTER TABLE` operations that internally rebuilt tables sometimes resulted in lost rows if a concurrent purge happened.
97+
98+
* [PS-9719](https://perconadev.atlassian.net/browse/PS-9719): When `binlog_transaction_dependency_tracking` was changed during a high-load workload, MySQL encountered a segmentation fault.
99+
100+
* [PS-9723](https://perconadev.atlassian.net/browse/PS-9723): MySQL server exited in `xpl::Ssl_context::~Ssl_context()` under heavy load of `ALTER INSTANCE RELOAD TLS` queries.
101+
102+
* [PS-9753](https://perconadev.atlassian.net/browse/PS-9753): Applied an optimizer patch from Enhanced MySQL to restore correct handling of const tables in `test_quick_select()`.
103+
104+
* [PS-9764](https://perconadev.atlassian.net/browse/PS-9764): Added clang-20 to Azure Pipelines and fixed clang-20 compilation issues.
105+
106+
* [PS-9777](https://perconadev.atlassian.net/browse/PS-9777): The `binlog_utils_udf` plugin did not handle `binlog.index` entries the same as the Percona Server code did.
107+
108+
* [PS-9780](https://perconadev.atlassian.net/browse/PS-9780): The maximum size of `audit_log_filter` rule was increased from 1024 characters to 16 000 characters.
109+
110+
* PS-9661: The encryption of system tablespaces using `component_keyring_kmip` failed.
