 - `pkgs.nextcloud27` has been removed since it's EOL.
 
+- The `environment.noXlibs` option has been removed. It was a common source of unexpected rebuilds and breakage that was often hard to diagnose.
+  If you need to disable certain libraries, you're encouraged to add your own overlay to your configuration that targets the packages you care about.
+
 - `frigate` was updated past 0.14.0. This release includes various breaking changes, so please go read the [release notes](https://github.com/blakeblackshear/frigate/releases/tag/v0.14.0).
    Most prominently access to the webinterface and API are now protected by authentication. Retrieve the auto-created
    admin account from the `frigate.service` journal after upgrading.
