- `services.postgresql.extraPlugins` changed its type from just a list of packages to also a function that returns such a list.
For example a config line like ``services.postgresql.extraPlugins = with pkgs.postgresql_11.pkgs; [ postgis ];`` is recommended to be changed to ``services.postgresql.extraPlugins = ps: with ps; [ postgis ];``;
- `services.openssh` now has an option `authorizedKeysInHomedir`, controlling whether `~/.ssh/authorizedKeys` is
added to `authorizedKeysFiles`.
::: {.note}
This option currently defaults to `true` for NixOS 24.05, preserving the previous behaviour.
This is expected to change in NixOS 24.11.
:::
::: {.warning}
Users should check that their SSH keys are in `users.users.*.openssh`, or that they have another way to access
and administer the system, before setting this option to `false`.
:::
- [`matrix-synapse`](https://element-hq.github.io/synapse/) homeserver module now supports configuring UNIX domain socket [`listeners`](#opt-services.matrix-synapse.settings.listeners) through the `path` option.
The default replication worker on the main instance has been migrated away from TCP sockets to UNIX domain sockets.
