-`titaniumenv`, `titanium`, and `titanium-alloy` have been removed due to lack of maintenance in Nixpkgs []{#sec-nixpkgs-release-25.05-incompatibilities-titanium-removed}.
- androidenv has been improved:
- All versions specified in composeAndroidPackages now track the latest. Android packages are automatically updated on unstable, and run the androidenv test suite on every update.
- Many androidenv packages are now searchable on [search.nixos.org](https://search.nixos.org).
- We now use the latest Google repositories, which should improve aarch64-darwin compatibility. The SDK now additionally evaluates on aarch64-linux, though not all packages are functional.
-`gerbera` now has wavpack support.
- GOverlay has been updated to 1.2, please check the [upstream changelog](https://github.com/benjamimgois/goverlay/releases) for more details.
- A new `pkgs.mattermost.buildPlugin` function has been added, which allows plugins to be built from source, including webapp frontends with a supported package-lock.json. See the Mattermost NixOS test and [manual](https://nixos.org/manual/nixpkgs/unstable/#sec-mattermost-plugins-build) for an example.
- Note that the Mattermost module will create an account _without_ a well-known UID if the username differs from the default (`mattermost`). If you used Mattermost with a nonstandard username, you may want to review the module changes before upgrading.
