MySQL HeatWave now supports MySQL database 8.3.0 and 8.0.36 versions. MySQL 8.3.0 is an Innovation release, meaning it will have new features and bug fixes and will be supported until the next Innovation release. With this new Innovation series, the existing 8.0.x releases will focus on security and bug fixes only. New MySQL DB systems are now based on the 8.0.36 version, and you can optionally select the 8.3.0 version when creating a new DB system. For existing DB systems, you must manually upgrade MySQL Server, such as from version 8.0.35 to 8.0.36 or 8.3.0.

Both versions, 8.3.0 (Innovation) and 8.0.36, are of production-grade quality. If you desire access to the latest features and improvements and enjoy staying on top of the latest technologies, the MySQL Innovation releases might be the best fit for you. On the other hand, if your application requires established behavior, then 8.0.x releases are more suitable.
