Getting Ready for the Future
End-of-Life Timeline
It is important to know when support for MySQL 8.0 ends. The official end-of-life date is April 30, 2026. After this date, you will not get security updates or bug fixes. You also will not get technical support. This can make your database unsafe and not reliable. Auditors might ask why you use software with no support. This can make it harder to follow rules. Using MySQL 8.0 after support ends means more risk of security problems and downtime. Old software can cost more money and cause more trouble.
Tip: Start planning your upgrade early. This helps you avoid problems and keeps your data safe.
No security updates after April 30, 2026
No bug fixes or technical support
