## 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`
- `minio` removed support for its legacy filesystem backend in [RELEASE.2022-10-29T06-21-33Z](https://github.com/minio/minio/releases/tag/RELEASE.2022-10-29T06-21-33Z). This means if your storage was created with the old format, minio will no longer start. Unfortunately minio doesn't provide a an automatic migration, they only provide [instructions how to manually convert the node](https://min.io/docs/minio/windows/operations/install-deploy-manage/migrate-fs-gateway.html). To facilitate this migration we keep around the last version that still supports the old filesystem backend as `minio_legacy_fs`. Use it via `services.minio.package = minio_legacy_fs;` to export your data before switching to the new version. See the corresponding [issue](https://github.com/NixOS/nixpkgs/issues/199318) for more details.
- `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 explicitly 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 explicitly 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 explicitly set this option to `true`, or configure your firewall.
- The Nginx module now validates the syntax of config files at build time. For more complex configurations (using `include` with out-of-store files notably) you may need to disable this check by setting [services.nginx.validateConfig](#opt-services.nginx.validateConfig) to `false`.
- 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)
- The module `usbmuxd` now has the ability to change the package used by the daemon. In case you're experiencing issues with `usbmuxd` you can try an alternative program like `usbmuxd2`. Available as [services.usbmuxd.package](#opt-services.usbmuxd.package)
- `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.
- `services.peertube` now requires you to specify the secret file `secrets.secretsFile`. It can be generated by running `openssl rand -hex 32`.
Before upgrading, read the release notes for PeerTube:
- [Release v5.0.0](https://github.com/Chocobozzz/PeerTube/releases/tag/v5.0.0)
And backup your data.
- `services.chronyd` is now started with additional systemd sandbox/hardening options for better security.
- The module `services.headscale` was refactored to be compliant with [RFC 0042](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md). To be precise, this means that the following things have changed:
- Most settings has been migrated under [services.headscale.settings](#opt-services.headscale.settings) which is an attribute-set that
will be converted into headscale's YAML config format. This means that the configuration from
[headscale's example configuration](https://github.com/juanfont/headscale/blob/main/config-example.yaml)
can be directly written as attribute-set in Nix within this option.
- `nixos/lib/make-disk-image.nix` can now mutate EFI variables, run user-provided EFI firmware or variable templates. This is now extensively documented in the NixOS manual.
- `services.grafana` listens only on localhost by default again. This was changed to upstreams default of `0.0.0.0` by accident in the freeform setting conversion.
- 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.
- Enabling global redirect in `services.nginx.virtualHosts` now allows one to add exceptions with the `locations` option.
- A new option `recommendedBrotliSettings` has been added to `services.nginx`. Learn more about compression in Brotli format [here](https://github.com/google/ngx_brotli/blob/master/README.md).
- [Garage](https://garagehq.deuxfleurs.fr/) version is based on [system.stateVersion](options.html#opt-system.stateVersion), existing installations will keep using version 0.7. New installations will use version 0.8. In order to upgrade a Garage cluster, please follow [upstream instructions](https://garagehq.deuxfleurs.fr/documentation/cookbook/upgrading/) and force [services.garage.package](options.html#opt-services.garage.package) or upgrade accordingly [system.stateVersion](options.html#opt-system.stateVersion).
- 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 `firewall` and `nat` module now has a nftables based implementation. Enable `networking.nftables` to use it.
- 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.
- [Xastir](https://xastir.org/index.php/Main_Page) can now access AX.25 interfaces via the `libax25` package.
