A couple of weeks ago, my colleague Marco Tusa published an important announcement titled “Do Not Upgrade to Any Version of MySQL After 8.0.37.” The announcement highlighted a critical issue in MySQL 8.0.38, MySQL 8.4.1, and MySQL 9.0.0 that caused database server crashes.
Good news! The upcoming minor releases for the community edition of MySQL and Percona Server for MySQL have already resolved this issue. Both teams worked diligently and independently on the solution. We would like to commend the Oracle team for their swift response to this problem.
The key takeaway is that MySQL 8.0.39, MySQL 8.4.2, and MySQL 9.0.1 will no longer contain this issue in their codebase.
As an additional note, we have decided to bypass the releases of Percona Server for MySQL 8.0.38 and 8.4.1. We will directly move from 8.0.37 to 8.0.39 and from 8.4.0 to 8.4.2. This approach will help everyone remember to avoid the affected versions and allow us to reduce the lead time between upstream and Percona releases. If you encounter any stability issues with these or other versions, the experts at Percona are available to assist you with upgrades, downgrades, and configuration matters. We encourage you to explore our range of MySQL-related services.
We anticipate releasing Percona Server for MySQL 8.0.37 and 8.4.0 by the end of August and 8.0.39 and 8.4.2 at the beginning of Q4 2024.
If you haven’t yet upgraded to MySQL 8 and this news makes you hesitant to do so, Percona offers consultative and operational support for MySQL 5.7 for up to three years post-EOL.
