They've got until 9.0 for that, it just gives deprecation warnings in 8.4.

More specifically, mysql_native_password is disabled by default in 8.4, but can be re-enabled if needed: https://www.skeema.io/blog/2024/05/14/mysql84-surprises/#aut...

Deprecation warnings are in 8.0. It's disabled in 8.4.

If you are up-to-date with all your libraries it all should go well, but if some project is stuck on some old code, mostly old mysql libraries, one might get surprises when doing the switch away.
