- custom OVMF package (e.g.: `pkgs.OVMFFull` with HTTP, CSM and Secure Boot support) ([`virtualisation.libvirtd.qemu.ovmf.package`](options.html#opt-virtualisation.libvirtd.qemu.ovmf.package)).
- The `cawbird` Twitter client now uses its own API keys to count as different application than upstream builds. This is done to evade application-level rate limiting. While existing accounts continue to work, users may want to remove and re-register their account in the client to enjoy a better user experience and benefit from this change.
- A new option `services.prometheus.enableReload` has been added which can be enabled to reload the prometheus service when its config file changes instead of restarting.
- The option `services.prometheus.environmentFile` has been removed since it was causing [issues](https://github.com/NixOS/nixpkgs/issues/126083) and Prometheus now has native support for secret files, i.e. `basic_auth.password_file` and `authorization.credentials_file`.
- Dokuwiki now supports caddy! However
- the nginx option has been removed, in the new configuration, please use the `dokuwiki.webserver = "nginx"` instead.
- The "${hostname}" option has been deprecated, please use `dokuwiki.sites = [ "${hostname}" ]` instead
- The [services.unifi](options.html#opt-services.unifi.enable) module has been reworked, solving a number of issues. This leads to several user facing changes:
- The `services.unifi.dataDir` option is removed and the data is now always located under `/var/lib/unifi/data`. This is done to make better use of systemd state direcotiry and thus making the service restart more reliable.
- The unifi logs can now be found under: `/var/log/unifi` instead of `/var/lib/unifi/logs`.
- The unifi run directory can now be found under: `/run/unifi` instead of `/var/lib/unifi/run`.
- `security.pam.services.<name>.makeHomeDir` now uses `umask=0077` instead of `umask=0022` when creating the home directory.
- Loki has had another release. Some default values have been changed for the configuration and some configuration options have been renamed. For more details, please check [the upgrade guide](https://grafana.com/docs/loki/latest/upgrading/#240).
- `julia` now refers to `julia-stable` instead of `julia-lts`. In practice this means it has been upgraded from `1.0.4` to `1.5.4`.
- RetroArch has been upgraded from version `1.8.5` to `1.9.13.2`. Since the previous release was quite old, if you're having issues after the upgrade, please delete your `$XDG_CONFIG_HOME/retroarch/retroarch.cfg` file.
- hydrus has been upgraded from version `438` to `463`. Since upgrading between releases this old is advised against, be sure to have a backup of your data before upgrading. For details, see [the hydrus manual](https://hydrusnetwork.github.io/hydrus/help/getting_started_installing.html#big_updates).
- More jdk and jre versions are now exposed via `java-packages.compiler`.
- The sets `haskell.packages` and `haskell.compiler` now contain for every ghc version an attribute with the minor version dropped. E.g. for `ghc8107` there also now exists `ghc810`. Those attributes point to the same compilers and packagesets but have the advantage that e.g. `ghc92` stays stable when we update from `ghc925` to `ghc926`.
