- The `yeahwm` package and `services.xserver.windowManager.yeahwm` module were removed due to the package being broken and unmaintained upstream.
-`services.nixseparatedebuginfod.enable = true;` has been replaced by `services.nixseparatedebuginfod2.enable = true`. If you only use the official binary cache `https://cache.nixos.org` then no further configuration should be needed. If you have other https substituters, you can add them to `services.nixseparatedebuginfod2.subsituters`. SSH substituters are not supported by nixseparatedebuginfod2. Consider running nixseparatedebuginfod2 on the substituter instead, and pointing to it with the new option `environment.debuginfodServers`.
- The `services.snapserver` module has been migrated to use the settings option and render a configuration file instead of passing every option over the command line.
- The `services.meilisearch` module now always defaults to the latest version of meilisearch, as the previous `meilisearch_1_11` package was removed. This is only an issue if you were using the old version.
