# Percona Server for MySQL 8.3.0-1 (2024-04-16)
2+
3+
Get started with [Quickstart Guide for Percona Server for MySQL].
4+
5+
[Percona Server for MySQL 8.3.0-1] includes all the features and bug fixes available in the
6+
MySQL 8.3 Community Edition in addition to enterprise-grade features developed by Percona.
7+
8+
## Release highlights
9+
10+
This release merges the MySQL 8.3 code base.
11+
12+
Within this merge, Percona updates the Binary Log UDFs to make them compatible with new tagged GTIDs (Global Transaction Identifiers).
13+
14+
Improvements and bug fixes introduced by Oracle for MySQL 8.3 and included in Percona Server for MySQL are the following:
15+
16+
* Implements tagged GTIDs to group related transactions. This helps enhance replication management and simplify tracking transaction dependencies.
17+
18+
* Adds the `explain_json_format_version` server system variable. This variable allows selection between two JSON output formats for `EXPLAIN FORMAT=JSON` statements. Version 1, the default, offers the linear format used in prior versions. Version 2 provides an access path-based format, ensuring better future MySQL Optimizer compatibility.
19+
20+
## Deprecation or removal
21+
22+
A future release may remove deprecated features, variables and options. The usage of these deprecated items may cause a warning. We recommend migrating from deprecated variables and options as soon as possible.
23+
24+
This release removes the following features, variables and options:
25+
26+
* The `FLUSH HOSTS` statement was deprecated in MySQL 8.0.23 and has been removed. To clear the host cache, use `TRUNCATE TABLE performance_schema.host_cache` or `mysqladmin flush-hosts`.
27+
28+
* The `--skip-host-cache` server option has been removed. Start the server with the `--host-cache-size=0` option instead.
29+
30+
* The `--character-set-client-handshake` and `--old-style-user-limits` server options.
31+
32+
* The usage of writesets for conflict checks when the row-based logging is in effect is restricted. If `binlog_transaction_dependency_tracking` is set to `WRITESET` or `WRITESET_SESSION`, the `binlog_format` must be `ROW`. The `MIXED` value is no longer supported.
33+
34+
* The [Multi-threaded LRU flusher](..//xtradb-performance-improvements.md#multi-threaded-lru-flusher) feature is no longer supported.
35+
36+
* The `innodb_parallel_doublewrite_path` and `innodb_parallel_dblwr_encrypt` server options were deprecated in Percona Server 8.0.23 and have had no effect since that time. These options have now been removed.
37+
38+
Review the [MySQL 8.3 Release Notes] for detailed information and explore the new features!

## Bug fixes
41+

[PS-9018](https://perconadev.atlassian.net/browse/PS-9018): The replica stalls when `log_slave_updates=0` and a Data Definition Language (DDL) operation is executed against a non-replicated database on that replica.
