Also be aware that if you have set additional options in `services.wstunnel.{clients,servers}.<name>.extraArgs`,
that those might have been removed or modified upstream.
-`percona-server_8_4` and `mysql84` now have password authentication via the deprecated `mysql_native_password` disabled by default. This authentication plugin can be enabled via a CLI argument again, for detailed instructions and alternative authentication methods [see upstream documentation](https://dev.mysql.com/doc/refman/8.4/en/native-pluggable-authentication.html). The config file directive `default_authentication_plugin` has been removed.
- Percona has decided not to follow the LTS/ Innovation release scheme of upstream MySQL and thus [will only create releases for MySQL LTS versions](https://www.percona.com/blog/no-mysql-9-x-innovation-releases-from-percona/). Hence, the package names `percona-server_lts`, `percona-server_innovation`, `percona-xtrabackup_lts` and `percona-xtrabackup_innovation` are deprecated.
-`percona-server` and `percona-server_lts` now point towards the new LTS release `percona-server_8_4`. The previous LTS continues to be supported and is available as `percona-server_8_0`. The same is true for the supporting `percona-xtrabackup` tooling.
-`clang-tools_<version>` packages have been moved into `llvmPackages_<version>` (i.e. `clang-tools_18` is now `llvmPackages_18.clang-tools`).
- For convenience, the top-level `clang-tools` attribute remains and is now bound to `llvmPackages.clang-tools`.
- Top-level `clang_tools_<version>` attributes are now aliases; these will be removed in a future release.
