## Backward Incompatibilities {#sec-release-23.05-incompatibilities}

<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->

- `carnix` and `cratesIO` has been removed due to being unmaintained, use alternatives such as [naersk](https://github.com/nix-community/naersk) and [crate2nix](https://github.com/kolloch/crate2nix) instead.

- `borgbackup` module now has an option for inhibiting system sleep while backups are running, defaulting to off (not inhibiting sleep), available as [`services.borgbackup.jobs.<name>.inhibitsSleep`](#opt-services.borgbackup.jobs._name_.inhibitsSleep). 

- The EC2 image module no longer fetches instance metadata in stage-1. This results in a significantly smaller initramfs, since network drivers no longer need to be included, and faster boots, since metadata fetching can happen in parallel with startup of other services.
  This breaks services which rely on metadata being present by the time stage-2 is entered. Anything which reads EC2 metadata from `/etc/ec2-metadata` should now have an `after` dependency on `fetch-ec2-metadata.service`

- `services.sourcehut.dispatch` and the corresponding package (`sourcehut.dispatchsrht`) have been removed due to [upstream deprecation](https://sourcehut.org/blog/2022-08-01-dispatch-deprecation-plans/).

- The [services.snapserver.openFirewall](#opt-services.snapserver.openFirewall) module option default value has been changed from `true` to `false`. You will need to explicitely set this option to `true`, or configure your firewall.

- The [services.tmate-ssh-server.openFirewall](#opt-services.tmate-ssh-server.openFirewall) module option default value has been changed from `true` to `false`. You will need to explicitely set this option to `true`, or configure your firewall.

- The [services.unifi-video.openFirewall](#opt-services.unifi-video.openFirewall) module option default value has been changed from `true` to `false`. You will need to explicitely set this option to `true`, or configure your firewall.

- The EC2 image module previously detected and automatically mounted ext3-formatted instance store devices and partitions in stage-1 (initramfs), storing `/tmp` on the first discovered device. This behaviour, which only catered to very specific use cases and could not be disabled, has been removed. Users relying on this should provide their own implementation, and probably use ext4 and perform the mount in stage-2.

- The EC2 image module previously detected and activated swap-formatted instance store devices and partitions in stage-1 (initramfs). This behaviour has been removed. Users relying on this should provide their own implementation.

- Qt 5.12 and 5.14 have been removed, as the corresponding branches have been EOL upstream for a long time. This affected under 10 packages in nixpkgs, largely unmaintained upstream as well, however, out-of-tree package expressions may need to be updated manually.

- In `mastodon` it is now necessary to specify location of file with `PostgreSQL` database password. In `services.mastodon.database.passwordFile` parameter default value `/var/lib/mastodon/secrets/db-password` has been changed to `null`.

- The `nix.readOnlyStore` option has been renamed to `boot.readOnlyNixStore` to clarify that it configures the NixOS boot process, not the Nix daemon.

## Other Notable Changes {#sec-release-23.05-notable-changes}

<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->

- `vim_configurable` has been renamed to `vim-full` to avoid confusion: `vim-full`'s build-time features are configurable, but both `vim` and `vim-full` are *customizable* (in the sense of user configuration, like vimrc).

- The module for the application firewall `opensnitch` got the ability to configure rules. Available as [services.opensnitch.rules](#opt-services.opensnitch.rules)

- `services.mastodon` gained a tootctl wrapped named `mastodon-tootctl` similar to `nextcloud-occ` which can be executed from any user and switches to the configured mastodon user with sudo and sources the environment variables.

- The `dnsmasq` service now takes configuration via the
  `services.dnsmasq.settings` attribute set. The option
  `services.dnsmasq.extraConfig` will be deprecated when NixOS 22.11 reaches
  end of life.

- To reduce closure size in `nixos/modules/profiles/minimal.nix` profile disabled installation documentations and manuals. Also disabled `logrotate` and `udisks2` services.

- The minimal ISO image now uses the `nixos/modules/profiles/minimal.nix` profile.

- `mastodon` now supports connection to a remote `PostgreSQL` database.

- A new `virtualisation.rosetta` module was added to allow running `x86_64` binaries through [Rosetta](https://developer.apple.com/documentation/apple-silicon/about-the-rosetta-translation-environment) inside virtualised NixOS guests on Apple silicon. This feature works by default with the [UTM](https://docs.getutm.app/) virtualisation [package](https://search.nixos.org/packages?channel=unstable&show=utm&from=0&size=1&sort=relevance&type=packages&query=utm).

- The new option `users.motdFile` allows configuring a Message Of The Day that can be updated dynamically.

- Resilio sync secret keys can now be provided using a secrets file at runtime, preventing these secrets from ending up in the Nix store.

- The `services.fwupd` module now allows arbitrary daemon settings to be configured in a structured manner ([`services.fwupd.daemonSettings`](#opt-services.fwupd.daemonSettings)).

- The `unifi-poller` package and corresponding NixOS module have been renamed to `unpoller` to match upstream.

- The new option `services.tailscale.useRoutingFeatures` controls various settings for using Tailscale features like exit nodes and subnet routers. If you wish to use your machine as an exit node, you can set this setting to `server`, otherwise if you wish to use an exit node you can set this setting to `client`. The strict RPF warning has been removed as the RPF will be loosened automatically based on the value of this setting.
