 - 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.

 - 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.

 - In the ncdns module, the default value of `services.ncdns.address` has been changed to the IPv6 loopback address (`::1`).
 
+- `openldap` (and therefore the slapd LDAP server) were updated to version 2.6.2. The project introduced backwards-incompatible changes, namely the removal of the bdb, hdb, ndb, and shell backends in slapd. Therefore before updating, dump your database `slapcat -n 1` in LDIF format, and reimport it after updating your `services.openldap.settings`, which represents your `cn=config`.

 - `openssh` has been update to 8.9p1, changing the FIDO security key middleware interface.
 
 - `git` no longer hardcodes the path to openssh' ssh binary to reduce the amount of rebuilds. If you are using git with ssh remotes and do not have a ssh binary in your enviroment consider adding `openssh` to it or switching to `gitFull`.
