Congratulations to Our Friends at Oracle with the MySQL 8.0 GA Release!

It is a great today for whole MySQL community: MySQL 8.0 was just released as GA!

Geir Høydalsvik has a great summary in his “What’s New in MySQL 8.0” blog post. You can find additional information about MySQL 8.0 Replication and MySQL 8.0 Document Store that is also worth reading.

If you can’t wait to upgrade to MySQL 8.0, please make sure to read the Upgrading to MySQL 8.0 section in the manual, and pay particular attention to changes to Connection Authentication. It requires special handling for most applications.

Also keep in mind that while MySQL 8.0 passed through an extensive QA process, this is the first GA release. It is not yet as mature and polished as MySQL 5.7. If you’re just now starting application development, however, you should definitely start with MySQL 8.0 — by the time you launch your application, 8.0 will be good. 

All of us at Percona – and me personally – are very excited about this release. You can learn more details about what we expect from it in our Why We’re Excited about MySQL 8.0 webinar recording.
