 - `rocmPackages_6` has been removed. `rocmPackages` has been updated to ROCm 7.x. Out of tree packages may rely on obsolete hipblas APIs or compile time constant warp size and need to be updated.
 
+- `mysql80` has been removed. Please update to `mysql84` or `mariadb`. See the [upgrade guide](https://mariadb.com/kb/en/upgrading-from-mysql-to-mariadb/) for more information.

 - `services.prometheus.exporters.rspamd` has been removed. It relied on the Rspamd /stat endpoint via the JSON exporter. You can use the Rspamd [/metrics](https://docs.rspamd.com/developers/protocol#controller-http-endpoints) endpoint directly instead.
 
 - The Bash implementation of the `nixos-rebuild` program is removed. All switchable systems now use the Python rewrite. Any prior usage of `system.rebuild.enableNg` must now be removed. If you have any outstanding issues with the new implementation, please open an issue on GitHub.
