- The `mime_types_file` setting is now set to `"${pkgs.mailcap}/etc/mime.types"` to prevent errors.
For a complete list of changes, please see [their announcement](https://blog.prosody.im/prosody-13.0.0-released/).
- HTTP3 support has been enabled in in `nginx`, `openresty`, `angie` and `tengine`. The `nginxQuic` and `angieQuic` package flavors have been removed.
- 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-`services.nixseparatedebuginfod.enable = true;` has been replaced by `services.nixseparatedebuginfod2.enable = true`.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`.
