Hi @yd7474 Thanks for posting your question in the Microsoft Q&A forum
Can you please share the screenshot of what you are referring to?
The upgrade is for the major version 5.7 to 8.0, 8.0.21 -> 8.0.31 is a minor version and it is updated during maintenance.
8.0.31 is the engine version. query the version after connecting to the database, I tried to create MySQL flex with the latest version and found the latest version.
