- [sitespeed-io](https://sitespeed.io), a tool that can generate metrics (timings, diagnostics) for websites. Available as [services.sitespeed-io](#opt-services.sitespeed-io.enable).
- [Apache Guacamole](https://guacamole.apache.org/), a cross-platform, clientless remote desktop gateway. Available as [services.guacamole-server](#opt-services.guacamole-server.enable) and [services.guacamole-client](#opt-services.guacamole-client.enable) services.
- The `boot.loader.raspberryPi` options have been marked deprecated, with intent for removal for NixOS 24.11. They had a limited use-case, and do not work like people expect. They required either very old installs ([before mid-2019](https://github.com/NixOS/nixpkgs/pull/62462)) or customized builds out of scope of the standard and generic AArch64 support. That option set never supported the Raspberry Pi 4 family of devices.
-`python3.pkgs.sequoia` was removed in favor of `python3.pkgs.pysequoia`. The latter package is based on upstream's dedicated repository for sequoia's Python bindings, where the Python bindings from [gitlab:sequoia-pgp/sequoia](https://gitlab.com/sequoia-pgp/sequoia) were removed long ago.
- The latest version of `clonehero` now stores custom content in `~/.clonehero`. See the [migration instructions](https://clonehero.net/2022/11/29/v23-to-v1-migration-instructions.html). Typically, these content files would exist along side the binary, but the previous build used a wrapper script that would store them in `~/.config/unity3d/srylain Inc_/Clone Hero`.
- The `services.hostapd` module was rewritten to support `passwordFile` like options, WPA3-SAE, and management of multiple interfaces. This breaks compatibility with older configurations.
-`hostapd` is now started with additional systemd sandbox/hardening options for better security.
-`services.hostapd.interface` was replaced with a per-radio and per-bss configuration scheme using [services.hostapd.radios](#opt-services.hostapd.radios).
-`services.hostapd.wpa` has been replaced by [services.hostapd.radios.<name>.networks.<name>.authentication.wpaPassword](#opt-services.hostapd.radios._name_.networks._name_.authentication.wpaPassword) and [services.hostapd.radios.<name>.networks.<name>.authentication.saePasswords](#opt-services.hostapd.radios._name_.networks._name_.authentication.saePasswords) which configure WPA2-PSK and WP3-SAE respectively.
- The default authentication has been changed to WPA3-SAE. Options for other (legacy) schemes are still available.
-`mariadb` now defaults to `mariadb_1011` instead of `mariadb_106`, meaning the default version was upgraded from 10.6.x to 10.11.x. See the [upgrade notes](https://mariadb.com/kb/en/upgrading-from-mariadb-10-6-to-mariadb-10-11/) for potential issues.
-`getent` has been moved from `glibc`'s `bin` output to its own dedicated output, reducing closure size for many dependents. Dependents using the `getent` alias should not be affected; others should move from using `glibc.bin` or `getBin glibc` to `getent` (which also improves compatibility with non-glibc platforms).
-`etcd` has been updated to 3.5, you will want to read the [3.3 to 3.4](https://etcd.io/docs/v3.5/upgrades/upgrade_3_4/) and [3.4 to 3.5](https://etcd.io/docs/v3.5/upgrades/upgrade_3_5/) upgrade guides
-`consul` has been updated to `1.16.0`. See the [release note](https://github.com/hashicorp/consul/releases/tag/v1.16.0) for more details. Once a new Consul version has started and upgraded its data directory, it generally cannot be downgraded to the previous version.
-`himalaya` has been updated to `0.8.0`, which drops the native TLS support (in favor of Rustls) and add OAuth 2.0 support. See the [release note](https://github.com/soywod/himalaya/releases/tag/v0.8.0) for more details.
- The [services.caddy.acmeCA](#opt-services.caddy.acmeCA) option now defaults to `null` instead of `"https://acme-v02.api.letsencrypt.org/directory"`, to use all of Caddy's default ACME CAs and enable Caddy's automatic issuer fallback feature by default, as recommended by upstream.
-`util-linux` is now supported on Darwin and is no longer an alias to `unixtools`. Use the `unixtools.util-linux` package for access to the Apple variants of the utilities.
-`services.ddclient` has been removed on the request of the upstream maintainer because it is unmaintained and has bugs. Please switch to a different software like `inadyn` or `knsupdate`.
- The `vlock` program from the `kbd` package has been moved into its own package output and should now be referenced explicitly as `kbd.vlock` or replaced with an alternative such as the standalone `vlock` package or `physlock`.
-`fileSystems.<name>.autoFormat` now uses `systemd-makefs`, which does not accept formatting options. Therefore, `fileSystems.<name>.formatOptions` has been removed.
-`fileSystems.<name>.autoResize` now uses `systemd-growfs` to resize the file system online in stage 2. This means that `f2fs` and `ext2` can no longer be auto resized, while `xfs` and `btrfs` now can be.
- The `services.vaultwarden.config` option default value was changed to make Vaultwarden only listen on localhost, following the [secure defaults for most NixOS services](https://github.com/NixOS/nixpkgs/issues/100192).
-`services.lemmy.settings.federation` was removed in 0.17.0 and no longer has any effect. To enable federation, the hostname must be set in the configuration file and then federation must be enabled in the admin web UI. See the [release notes](https://github.com/LemmyNet/lemmy/blob/c32585b03429f0f76d1e4ff738786321a0a9df98/RELEASES.md#upgrade-instructions) for more details.
- The following packages in `haskellPackages` have now a separate bin output: `cabal-fmt`, `calligraphy`, `eventlog2html`, `ghc-debug-brick`, `hindent`, `nixfmt`, `releaser`. This means you need to replace e.g. `"${pkgs.haskellPackages.nixfmt}/bin/nixfmt"` with `"${lib.getBin pkgs.haskellPackages.nixfmt}/bin/nixfmt"` or `"${lib.getExe pkgs.haskellPackages.nixfmt}"`. The binaries also won’t be in scope if you rely on them being installed e.g. via `ghcWithPackages`. `environment.packages` picks the `bin` output automatically, so for normal installation no intervention is required. Also, toplevel attributes like `pkgs.nixfmt` are not impacted negatively by this change.
-`spamassassin` no longer supports the `Hashcash` module. The module needs to be removed from the `loadplugin` list if it was copied over from the default `initPreConf` option.
- The Caddy module gained a new option named `services.caddy.enableReload` which is enabled by default. It allows reloading the service instead of restarting it, if only a config file has changed. This option must be disabled if you have turned off the [Caddy admin API](https://caddyserver.com/docs/caddyfile/options#admin). If you keep this option enabled, you should consider setting [`grace_period`](https://caddyserver.com/docs/caddyfile/options#grace-period) to a non-infinite value to prevent Caddy from delaying the reload indefinitely.
- mdraid support is now optional. This reduces initramfs size and prevents the potentially undesired automatic detection and activation of software RAID pools. It is disabled by default in new configurations (determined by `stateVersion`), but the appropriate settings will be generated by `nixos-generate-config` when installing to a software RAID device, so the standard installation procedure should be unaffected. If you have custom configs relying on mdraid, ensure that you use `stateVersion` correctly or set `boot.swraid.enable` manually.
- The Cinnamon module now enables XDG desktop integration by default. If you are experiencing collisions related to xdg-desktop-portal-gtk you can safely remove `xdg.portal.extraPortals = [ pkgs.xdg-desktop-portal-gtk ];` from your NixOS configuration.
-`fontconfig` now defaults to using greyscale antialiasing instead of subpixel antialiasing because of a [recommendation from one of the downstreams](https://gitlab.freedesktop.org/fontconfig/fontconfig/-/issues/337). You can change this value by configuring [](#opt-fonts.fontconfig.subpixel.rgba) accordingly.
- The latest available version of Nextcloud is v27 (available as `pkgs.nextcloud27`). The installation logic is as follows:
- If [`services.nextcloud.package`](#opt-services.nextcloud.package) is specified explicitly, this package will be installed (**recommended**)
- If [`system.stateVersion`](#opt-system.stateVersion) is >=23.11, `pkgs.nextcloud27` will be installed by default.
- If [`system.stateVersion`](#opt-system.stateVersion) is >=23.05, `pkgs.nextcloud26` will be installed by default.
- Please note that an upgrade from v25 (or older) to v27 directly is not possible. Please upgrade to `nextcloud26` (or earlier) first. Nextcloud prohibits skipping major versions while upgrading. You can upgrade by declaring [`services.nextcloud.package = pkgs.nextcloud26;`](options.html#opt-services.nextcloud.package).
- New options were added to `services.searx` for better SearXNG support, including options for the built-in rate limiter and bot protection and automatically configuring a local redis server.
- A new option was added to the virtualisation module that enables specifying explicitly named network interfaces in QEMU VMs. The existing `virtualisation.vlans` is still supported for cases where the name of the network interface is irrelevant.
-`services.fail2ban.jails` can now be configured with attribute sets defining settings and filters instead of lines. The stringed options `daemonConfig` and `extraSettings` have respectively been replaced by `daemonSettings` and `jails.DEFAULT.settings` which use attribute sets.
- The module [services.ankisyncd](#opt-services.ankisyncd.package) has been switched to [anki-sync-server-rs](https://github.com/ankicommunity/anki-sync-server-rs) from the old python version, which was difficult to update, had not been updated in a while, and did not support recent versions of anki.
Unfortunately all servers supporting new clients (newer version of anki-sync-server, anki's built in sync server and this new rust package) do not support the older sync protocol that was used in the old server, so such old clients will also need updating and in particular the anki package in nixpkgs is also being updated in this release.
The module update takes care of the new config syntax and the data itself (user login and cards) are compatible, so users of the module will be able to just log in again after updating both client and server without any extra action.
-`services.nginx` gained a `defaultListen` option at server-level with support for PROXY protocol listeners, also `proxyProtocol` is now exposed in `services.nginx.virtualHosts.<name>.listen` option. It is now possible to run PROXY listeners and non-PROXY listeners at a server-level, see [#213510](https://github.com/NixOS/nixpkgs/pull/213510/) for more details.
-`services.prometheus.exporters` has a new exporter to monitor electrical power consumption based on PowercapRAPL sensor called [Scaphandre](https://github.com/hubblo-org/scaphandre), see [#239803](https://github.com/NixOS/nixpkgs/pull/239803) for more details.
- The module `services.calibre-server` has new options to configure the `host`, `port`, `auth.enable`, `auth.mode` and `auth.userDb` path, see [#216497](https://github.com/NixOS/nixpkgs/pull/216497/) for more details.
-`services.prometheus.exporters` has a new [exporter](https://github.com/hipages/php-fpm_exporter) to monitor PHP-FPM processes, see [#240394](https://github.com/NixOS/nixpkgs/pull/240394) for more details.
-`programs.gnupg.agent.pinentryFlavor` is now set in `/etc/gnupg/gpg-agent.conf`, and will no longer take precedence over a `pinentry-program` set in `~/.gnupg/gpg-agent.conf`.
