+# Azure Database For MySQL Flexible Server May 2024 Maintenance
+
+We're pleased to announce the May 2024 maintenance for Azure Database for MySQL Flexible Server. This maintenance incorporates several new features and improvement, along with known issue fix, and security patches.
+
+## Engine version changes
+No engine version upgrade in this maintenance
+
+To check your engine version, run `SELECT VERSION();` command at the MySQL prompt
+
+## Features
+### A very exciting feature that would be announced during Microsoft Build 2024
+- We are excited to announce that significant performance enhancements will be introduced in our upcoming update. Full details will be shared at the MS Build event. We appreciate your patience and look forward to unveiling these advancements, which are designed to significantly improve the efficiency and performance of your database operations.
+
+## Improvement
+- Improved server restart logic, server restart has a timeout of 2 hours for none burstable servers, 4 hours timeout for burstable servers. After server restart workflow timeout, it would roll back and set the server state to Succeeded.
+- Improved the data-in replication procedures to show the real error message and safe exit when exception happens.
+- Improved the read replica creation workflow to precheck the VNet setting.
+    
+## Known Issues Fix
+- Fixed the issue that the server parameter max_connections and table_open_cache can't be configured correctly
+- Fixed the issue where executing `CREATE AADUSER IF NOT EXISTS 'myuser' IDENTIFIED BY 'CLIENT_ID'` when the user already exists incorrectly set the binlog record, affecting replica and high availability functionalities.
