- Pulseaudio has been upgraded to version 15.0 and now optionally [supports additional Bluetooth audio codecs](https://www.freedesktop.org/wiki/Software/PulseAudio/Notes/15.0/#supportforldacandaptxbluetoothcodecsplussbcxqsbcwithhigher-qualityparameters) like aptX or LDAC, with codec switching support being available in `pavucontrol`. This feature is disabled by default but can be enabled by using `hardware.pulseaudio.package = pkgs.pulseaudioFull;`.
Existing 3rd party modules that provided similar functionality, like `pulseaudio-modules-bt` or `pulseaudio-hsphfpd` are deprecated and have been removed.
- PostgreSQL now defaults to major version 14.
- The new [`postgresqlTestHook`](https://nixos.org/manual/nixpkgs/stable/#sec-postgresqlTestHook) runs a PostgreSQL server for the duration of package checks.
- [`kops`](https://kops.sigs.k8s.io) defaults to 1.22.4, which will enable [Instance Metadata Service Version 2](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html) and require tokens on new clusters with Kubernetes 1.22. This will increase security by default, but may break some types of workloads. See the [release notes](https://kops.sigs.k8s.io/releases/1.22-notes/) for details.
