# Release 25.11 ("Xantusia", 2025.11/??) {#sec-release-25.11} ## Highlights {#sec-release-25.11-highlights} - `nixos-rebuild-ng`, a full rewrite of `nixos-rebuild` in Python, is enabled by default from this release. You can disable it by setting [](#opt-system.rebuild.enableNg) to `false` in your configuration if you need, but please report any issues. It is expected that the next major version of NixOS (26.05) will remove the {option}`system.rebuild.enableNg` option. - `rEFInd`, a graphical boot manager for UEFI systems, can now be used through [](#opt-boot.loader.refind.enable). - Secure boot support can now be enabled for the Limine bootloader through {option}`boot.loader.limine.secureBoot.enable`. Bootloader install script signs the bootloader, then kernels are hashed during system rebuild and written to a config. This allows Limine to boot only the kernels installed through NixOS system. - The default PostgreSQL version for new NixOS installations (i.e. with `system.stateVersion >= 25.11`) is v17. - Added `nixos-init`, a Rust-based bashless initialization system for systemd initrd. This allows to build NixOS systems without any interpreter. Enable via `system.nixos-init.enable = true;`. - The NetworkManager module does not ship with a default set of VPN plugins anymore. All required VPN plugins must now be explicitly configured in [`networking.networkmanager.plugins`](#opt-networking.networkmanager.plugins). - The Qt 5-based versions of KDE Gear, Plasma, Maui and Deepin have been removed. Users are advised to migrate to Plasma 6 and Gear 25.08, available under `kdePackages`. - Syncthing has been updated to version 2.0.0. - COSMIC DE has been updated to the beta version, bringing it closer to its first stable release. This includes updates to its core components, applications, and overall stability. ## New Modules {#sec-release-25.11-new-modules} - [byedpi](https://github.com/hufrea/byedpi), a DPI bypass service.

All switchable systems now use the Rust rewrite. Any prior usage of `system.switch.enableNg` must now be removed. If you have any outstanding issues with the new implementation, please open an issue on GitHub. - The `no-broken-symlink` build hook now also fails builds whose output derivation contains links to $TMPDIR (typically /build, which contains the build directory). - `hardware.amdgpu.amdvlk` and the `amdvlk` package have been removed, as they have been deprecated by AMD. These have been replaced with the RADV driver from Mesa, which is enabled by default. - Linux 5.4 and all its variants have been removed since mainline will reach its end of life within the support-span of 25.11. - The `services.polipo` module has been removed as `polipo` is unmaintained and archived upstream. - `boot.enableContainers` is only turned on when a declarative NixOS container is defined in `containers`. If you use the `nixos-container` tool for imperative container management, set `boot.enableContainers = true;` explicitly. - `services.parsoid` and the `nodePackages.parsoid` package have been removed, as the JavaScript-based version this module uses is not compatible with modern MediaWiki versions. - `virtualisation.lxd` has been removed due to lack of Nixpkgs maintenance. Users can migrate to `virtualisation.incus`, a fork of LXD, as a replacement. See [Incus migration documentation](https://linuxcontainers.org/incus/docs/main/howto/server_migrate_lxd/) for migration information. - `virtualisation.libvirtd` now uses OVMF images shipped with QEMU for UEFI machines. `virtualisation.libvirtd.qemu.ovmf` has been removed. - OVMF images from underlying QEMU package are now made available under '/run/libvirt/nix-ovmf', fixing prior issues when using QEMU's automatic EFI firmware and feature handling, relied upon by GNOME Boxes, virsh, virt-manager, etc. - Domains that rely on automatic firmware and feature handling, i.e. `` need to trigger an update to `` and `` entries. Using `virsh edit ` and deleting aforementioned tags will cause libvirt to replace them with the new paths. - Configurations that relied on `virtualisation.libvirtd.qemu.ovmf` and had domains that did not use automatic firmware and feature handling, require a manual change to their domain configuration, updating `` and `` entries from old path to the new path. | Old Path | New Path | |----------------------------------------|--------------------------------------------------| | /run/libvirt/nix-ovmf/OVMF_CODE.fd | /run/libvirt/nix-ovmf/edk2-x86_64-code.fd | | /run/libvirt/nix-ovmf/OVMF_VARS.fd | /run/libvirt/nix-ovmf/edk2-i386-vars.fd | | /run/libvirt/nix-ovmf/OVMF_CODE.ms.fd | /run/libvirt/nix-ovmf/edk2-x86_64-secure-code.fd | | /run/libvirt/nix-ovmf/OVMF_VARS.ms.fd | /run/libvirt/nix-ovmf/edk2-i386-vars.fd | | /run/libvirt/nix-ovmf/AAVMF_CODE.fd | /run/libvirt/nix-ovmf/edk2-aarch64-code.fd | | /run/libvirt/nix-ovmf/AAVMF_VARS.fd | /run/libvirt/nix-ovmf/edk2-arm-vars.fd | | /run/libvirt/nix-ovmf/AAVMF_CODE.ms.fd | /run/libvirt/nix-ovmf/edk2-aarch64-code.fd | | /run/libvirt/nix-ovmf/AAVMF_VARS.ms.fd | /run/libvirt/nix-ovmf/edk2-arm-vars.fd | - The non-LTS Forgejo package (`forgejo`) has been updated to 12.0.0. This release contains breaking changes, see the [release blog post](https://forgejo.org/2025-07-release-v12-0/) for all the details and how to ensure smooth upgrades. - `sing-box` has been updated to 1.12.3, which includes a number of breaking changes, old configurations may need updating or they will cause the tool to fail to run. See the [change log](https://sing-box.sagernet.org/changelog/#1123) for details and [migration](https://sing-box.sagernet.org/migration/#1120) for how to update old configurations. - The Pocket ID module ([`services.pocket-id`][#opt-services.pocket-id.enable]) and package (`pocket-id`) has been updated to 1.0.0. Some environment variables have been changed or removed, see the [migration guide](https://pocket-id.org/docs/setup/migrate-to-v1/). - `services.seafile` has been removed, as it is unmaintained and outdated. See [the manual](https://manual.seafile.com/13.0/upgrade/upgrade_notes_for_13.0.x/#important-release-changes) for details and next steps. - The `zigbee2mqtt` package was updated to version 2.x, which contains breaking changes. See the [discussion](https://github.com/Koenkk/zigbee2mqtt/discussions/24198) for further information. - []{#sec-release-25.11-incompatibilities-sourcehut-removed} The `services.sourcehut` module and corresponding `sourcehut` packages were removed due to being broken and unmaintained. - The zookeeper project changed their logging tool to logback, therefore `services.zookeeper.logging` option has been updated to expect a logback compatible string. - The `dovecot` systemd service was renamed from `dovecot2` to `dovecot`. The former is now just an alias. Update any overrides on the systemd unit to the new name. - Configurations with `boot.initrd.systemd.enable && !boot.initrd.enable` will have their `init` script at `$toplevel/init` instead of `$toplevel/prepare-root`. This is because it does not make sense for systemd stage 1 to affect the `init` script when stage 1 is entirely disabled (e.g. containers). - `programs.goldwarden` has been removed, due to the software not working with newer versions of the Bitwarden and Vaultwarden servers, as well as it being abandoned upstream. - The `chatgpt-retrieval-plugin` package and `services.chatgpt-retrieval-plugin` module were removed due to the package having been broken since at least November 2024. - The `cardboard` package and `programs.cardboard` module were removed due to the package having been broken since at least November 2024. - The default `kops` version is now 1.33.0 and versions 1.30 and older have been dropped. See [Upgrading Kubernetes](https://kops.sigs.k8s.io/tutorial/upgrading-kubernetes/) for instructions on how to update kOps. - `programs.skim.fuzzyCompletions` has been removed in favor of adding the completions to the package itself. - `Prosody` has been updated to major release 13 which removed some obsoleted modules and brought a couple of major and breaking changes: - The `http_files` module is now disabled by default because it now requires `http_files_dir` to be configured. - The `vcard_muc` module has been removed and got replaced by the inbuilt `muc_vcard` module. - The `http_upload` module has been removed and you must migrate to the `http_file_share` module to stay XEP-0423 compliant. The `httpFileShare` options got expanded to better facility that. - The `admin_shell` module is now always being loaded to make `prosodyctl` functional. - The `mime_types_file` setting is now set to `"${pkgs.mailcap}/etc/mime.types"` to prevent errors. For a complete list of changes, please see [their announcement](https://blog.prosody.im/prosody-13.0.0-released/). - The `yeahwm` package and `services.xserver.windowManager.yeahwm` module were removed due to the package being broken and unmaintained upstream. - `services.nixseparatedebuginfod.enable = true;` has been replaced by `services.nixseparatedebuginfod2.enable = true`. If you only use the official binary cache `https://cache.nixos.org` then no further configuration should be needed. If you have other https substituters, you can add them to `services.nixseparatedebuginfod2.subsituters`. SSH substituters are not supported by nixseparatedebuginfod2. Consider running nixseparatedebuginfod2 on the substituter instead, and pointing to it with the new option `environment.debuginfodServers`. - The `services.snapserver` module has been migrated to use the settings option and render a configuration file instead of passing every option over the command line. - The `services.meilisearch` module now always defaults to the latest version of meilisearch, as the previous `meilisearch_1_11` package was removed. This is only an issue if you were using the old version. - `services.journald.gateway.user` and `services.journald.gateway.system` now defaults to `false`. This new behaviour matches the default behaviour of the [`systemd-journal-gatewayd`](https://www.freedesktop.org/software/systemd/man/latest/systemd-journal-gatewayd.service.html) service itself. - The `services.postgresql` module now sets up a systemd unit `postgresql.target`. Depending on `postgresql.target` guarantees that postgres is in read-write mode and initial/ensure scripts were executed. Depending on `postgresql.service` only guarantees a read-only connection. - The `services.mysql` module now restarts the database `on-abnormal`, which means that it now will be restarted in certain situations, it wasn't before. For example an OOM-kill. - The `services.tt-rss` module and package have been removed as upstream development ceased on 2025-11-01, and the source is no longer available officially. - The `services.siproxd` module has been removed as `siproxd` is unmaintained and broken with libosip 5.x. - The `services.postfixadmin` module has been removed due to a lack of active maintainers. - `services.tor.torsocks.enable` no longer defaults to true if Tor and Tor client functionality is enabled. - `netbox-manage` script created by the `netbox` module no longer uses `sudo -u netbox` internally. It can be run as root and will change it's user to `netbox` using `runuser` - `services.gateone` has been removed as the package was removed such that it does not work. - `services.quorum` has been removed as the `quorum` package was broken and abandoned upstream. - `orjail` package has been removed as it is broken by the latest firejail release and seems unmaintained. - `teleport` has been upgraded from major version 17 to major version 18. Refer to [upstream upgrade instructions](https://goteleport.com/docs/upgrading/overview/) and [release notes for v18](https://goteleport.com/docs/changelog/#1800-070325). - `services.dwm-status.extraConfig` was replaced by [RFC0042](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md)-compliant [](#opt-services.dwm-status.settings), which is used to generate the config file. `services.dwm-status.order` is now moved to [](#opt-services.dwm-status.settings.order), as it's a part of the config file. - `gitversion` was updated to 6.3.0, which includes a number of breaking changes, old configurations may need updating or they will cause the tool to fail to run. See the [6.0.0 release notes for GitVersion](https://github.com/GitTools/GitVersion/releases/tag/6.0.0) for details on the breaking changes, [the documentation on the configuration format](https://gitversion.net/docs/reference/configuration) for the new configuration specification, and [the documentation on version variables](https://gitversion.net/docs/reference/variables) for what is now supported. - `renovate` was updated to v41. See the upstream release notes for [v40](https://github.com/renovatebot/renovate/releases/tag/40.0.0) and [v41](https://github.com/renovatebot/renovate/releases/tag/41.0.0) for breaking changes. - The "NIXOS_EXTRA_MODULE_PATH" variable from configuration evaluation has been deprecated. We recommend a workflow where you update the expression files instead, but if you wish to continue to use this variable, you may do so with a module like: ```nix { imports = [ (builtins.getEnv "NIXOS_EXTRA_MODULE_PATH") ]; } ``` This has the benefit that your configuration hints at the non-standard workflow. - `i18n.inputMethod.fcitx5.plasma6Support` has been removed because qt6 is the only one used for fcitx5-configtool now. - `firezone` has changed how the `Everyone` group behaves. Service Accounts are no longer considered part of `Everyone`. - The `boot.readOnlyNixStore` has been removed. Control over bind mount options on `/nix/store` is now offered by the `boot.nixStoreMountOpts` option. - Direct use of `pkgs.formats.systemd` has been deprecated, and should now be instantiated with `pkgs.formats.systemd { }` similarly to other items in `pkgs.formats`. - The Postfix module has been updated and likely requires configuration changes: - The `services.postfix.sslCert` and `sslKey` options were removed and you now need to configure - [services.postfix.settings.main.smtpd_tls_chain_files](#opt-services.postfix.settings.main.smtpd_tls_chain_files) for server certificates, - [services.postfix.settings.main.smtp_tls_chain_files](#opt-services.postfix.settings.main) for client certificates. - `vmalert` now supports multiple instances with the option `services.vmalert.instances."".enable` - [`virtualisation.waydroid.package`](#opt-virtualisation.waydroid.package) now defaults to `waydroid-nftables` on systems with nftables enabled. - [`services.victorialogs.package`](#opt-services.victorialogs.package) now defaults to `victorialogs`, as `victoriametrics` no longer contains the VictoriaLogs binaries. - The `services.traccar.settings` attribute has been reworked. Instead of the previous flat attribute set the new implementation uses nested attribute sets. You need to update you configuration manually. For instance, `services.traccar.settings.loggerConsole` becomes `services.traccar.settings.logger.console`. - The `wstunnel` module was converted to RFC42-style settings, you will need to update your NixOS config if you make use of this module. - [private-gpt](https://github.com/zylon-ai/private-gpt) service has been removed by lack of maintenance upstream. - The `asterisk-lts` package was changed to v22 from v18. The default `asterisk` package was changed to v22 from v20. Asterisk version 18 has been dropped due to being EOL. The `asterisk-stable` (v20) package was unchanged. You may need to update /var/lib/asterisk to match the template files in `${asterisk-...}/var/lib/asterisk`. - NixOS display manager modules now strictly use tty1, where many of them previously used tty7. Options to configure display managers' VT have been dropped. A configuration with a display manager enabled will not start `getty@tty1.service`, even if the system is forced to boot into `multi-user.target` instead of `graphical.target`. - `river` 0.3.x has been renamed to `river-classic` upstream, and the package renamed accordingly. `programs.river` has been renamed to `programs.river-classic`. - `command-not-found` package is now disabled by default; it works only for nix-channels based systems, and requires setup for it to work. - The systemd target `kbrequest.target` is now unset by default, instead of being forcibly symlinked to `rescue.target`. In case you were relying on this behavior (Alt + ArrowUp on the tty causing the current target to be changed to `rescue.target`), you can restore it by setting `systemd.targets.rescue.aliases = [ "kbrequest.target" ];` in your configuration. - `miniflux` no longer uses the hstore PostgreSQL extension. Having the extension would prevent Miniflux from starting. In case you are managing your `miniflux` PostgreSQL database externally, disable the extension with `DROP EXTENSION IF EXISTS hstore;`. ## Other Notable Changes {#sec-release-25.11-notable-changes} - `services.clamsmtp` is unmaintained and was removed from Nixpkgs. - The latest available version of Nextcloud is v32 (available as `pkgs.nextcloud32`). 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 >=25.05, `pkgs.nextcloud32` will be installed by default. - If [`system.stateVersion`](#opt-system.stateVersion) is >=24.11, `pkgs.nextcloud31` will be installed by default. - `nextcloud30` is EOL and was thus removed. - Please note that an upgrade from v30 (or older) to v32 directly is not possible. Please upgrade to `nextcloud31` (or earlier) first. Nextcloud prohibits skipping major versions while upgrading. You can upgrade by declaring [`services.nextcloud.package = pkgs.nextcloud30;`](#opt-services.nextcloud.package). - `services.eris-server` was removed from Nixpkgs due to a hostile upstream. - `prosody` gained a config check option named `services.prosody.checkConfig` which runs `prosodyctl check config` and is turned on by default. - `services.dependency-track` removed its configuration of the JVM heap size. This lets the JVM choose its maximum heap size automatically, which should work much better in practice for most users. For deployments on systems with little RAM, it may now be necessary to manually configure a maximum heap size using {option}`services.dependency-track.javaArgs`. - `services.dnscrypt-proxy2` was renamed to `services.dnscrypt-proxy` to match the package name. The systemd service is now also `dnscrypt-proxy`, but the old name is still provided as an alias for backwards compatibility. - `services.dnscrypt-proxy` gains a `package` option to specify dnscrypt-proxy package to use. - `boot.plymouth` now has a [`package`](#opt-boot.plymouth.package) option to specify the package used in the module. - `services.limesurvey` now supports nginx as reverse-proxy. Available through [services.limesurvey.webserver](#opt-services.limesurvey.webserver). - `services.nextcloud.configureRedis` now defaults to `true` in accordance with upstream recommendations to have caching for file locking. See the [upstream doc](https://docs.nextcloud.com/server/31/admin_manual/configuration_files/files_locking_transactional.html) for further details. - mate-wayland-session 1.28.4 is now using the default wayfire decorator instead of firedecor, thus `services.xserver.desktopManager.mate.enableWaylandSession` is no longer shipping firedecor. If you are experiencing broken window decorations after upgrade, backup and remove `~/.config/mate/wayfire.ini` and re-login. - - A new option [](#opt-boot.isNspawnContainer) has been added. This option will be used to guard nspawn-specific configuration in NixOS since [](#opt-boot.isContainer) is also used for different container-runtimes such as LXC. - The new option is automatically set to `true` by the declarative container module and `nixos-container` when not using flakes. - Existing setups can be migrated by running either - `nixos-container update --config-file /path/to/the/config-file-in-use.nix` - `nixos-container update --config '/* config code */'` - Setting the option by hand in your configuration when using flakes. - In all other cases, you'll need to set this option to `true` yourself. - `boot.isNspawnContainer` being `true` implies [](#opt-boot.isContainer) being `true`. - Due to [deprecation of gnome-session X11 support](https://blogs.gnome.org/alatiera/2025/06/08/the-x11-session-removal/), `services.desktopManager.pantheon` now defaults to pantheon-wayland session. The X11 session has been removed, see [this issue](https://github.com/elementary/session-settings/issues/91) for details. - `bcachefs` file systems will now use the out-of-tree module for supported kernels. The in-tree module has been removed, and users will need to switch to kernels that support the out-of-tree module. - `services.filesender` and the package `filesender` have been removed because they depend on `simplesamlphp`. - `services.gitea` supports sending notifications with sendmail again. To do this, activate the parameter `services.gitea.mailerUseSendmail` and configure SMTP server. - `services.mattermost` has been updated to use the 10.11 ESR instead of 10.5. While this shouldn't break anyone, we also now package Mattermost 11 as mattermostLatest. Note that Mattermost 11 drops support for MySQL. The Mattermost module will assertion fail if you try to use MySQL with Mattermost 11; support for using MySQL with Mattermost will fully be removed in NixOS 26. - `simplesamlphp` has been removed since the package was severely outdated, unmaintained in nixpkgs and having known vulnerabilities. - `networking.wireless.networks.` now has an option to specify SSID, hence allowing duplicated SSID setup. The BSSID option is added along side with this. - Revamp of the ACME certificate acquisication and renewal process to help scale systems with lots (100+) of certificates. Units and targets have been reshaped to better support more specific dependency propagation and avoid superfluously triggering unchanged units: If a service requires a syntactically valid certificate to start it should now depend on the `acme-{certname}.service` unit. We now always generate initial self-signed certificates as this drastically simplifies the dependency structure. As a result, the option `security.acme.preliminarySelfsigned` has been removed. Instead of the previous `acme-finished-{certname}.target`s there are now `acme-order-renew-{certname}.service`s that will be activated in a delayed fashion to ensure that bootstrapping with servers like nginx that take part in the acquisition/renewal process works smoothly. Dependencies on `acme-finished` units should move to `acme-order-renew`. Note that system activation will complete before all certificates may have been renewed or acquired. - `php81` was removed. - `libvirt` now supports using `nftables` backend. - The `virtualisation.libvirtd.firewallBackend` option can be used to configure the firewall backend used by libvirtd. - The third-party `ant-contrib` is no longer included in the `ant` package. - `systemd.extraConfig` and `boot.initrd.systemd.extraConfig` was converted to RFC42-style `systemd.settings.Manager` and `boot.initrd.systemd.settings.Manager` respectively. - `systemd.watchdog.runtimeTime` was renamed to `systemd.settings.Manager.RuntimeWatchdogSec` - `systemd.watchdog.device` was renamed to `systemd.settings.Manager.WatchdogDevice` - `systemd.watchdog.rebootTime` was renamed to `systemd.settings.Manager.RebootWatchdogSec` - `systemd.watchdog.kexecTime` was renamed to `systemd.settings.Manager.KExecWatchdogSec` - `systemd.enableCgroupAccounting` was removed. Cgroup accounting now needs to be disabled directly using `systemd.settings.Manager.*Accounting`. - `services.logind.extraConfig` was converted to RFC42-style `services.logind.settings.Login`. - `services.ntpd-rs` now performs configuration validation. - Immich now has support for [VectorChord](https://github.com/tensorchord/VectorChord) when using the PostgreSQL configuration provided by `services.immich.database.enable`, which replaces `pgvecto-rs`. VectorChord support can be toggled with the option `services.immich.database.enableVectorChord`. Additionally, `pgvecto-rs` support is now disabled from NixOS 25.11 onwards using the option `services.immich.database.enableVectors`. This option will be removed fully in the future once Immich drops support for `pgvecto-rs` fully. See [Immich migration instructions](#module-services-immich-vectorchord-migration) - `services.restic.backups` now includes a `command` option for passing a command to the [--stdin-from-command](https://github.com/restic/restic/pull/4410) flag. - `services.postsrsd` now automatically integrates with the local Postfix instance, when enabled. This behavior can disabled using the [services.postsrsd.configurePostfix](#opt-services.postsrsd.configurePostfix) option. - `services.pfix-srsd` now automatically integrates with the local Postfix instance, when enabled. This behavior can disabled using the [services.pfix-srsd.configurePostfix](#opt-services.pfix-srsd.configurePostfix) option. - `services.monero` now includes the `environmentFile` option for adding secrets to the Monero daemon config. - `services.netbird.server` now uses dedicated packages split out due to relicensing of server components to AGPLv3 with version `0.53.0`, - `linux_libre` & `linux_latest_libre` have been removed due to a lack of maintenance. - `services.pds` has been renamed to `services.bluesky-pds`. - `services.xserver.desktopManager.deepin` and associated packages have been removed due to being unmaintained. See issue [#422090](https://github.com/NixOS/nixpkgs/issues/422090) for more details. - `services.matter-server` now hosts a debug dashboard on the configured port. Open the port on the firewall with `services.matter-server.openFirewall`. - The new option [networking.ipips](#opt-networking.ipips) has been added to create IP within IP kind of tunnels (including 4in6, ip6ip6 and ipip). With the existing [networking.sits](#opt-networking.sits) option (6in4), it is now possible to create all combinations of IPv4 and IPv6 encapsulation. - It is now possible to configure the default source address using the new options [networking.defaultGateway.source](#opt-networking.defaultGateway.source), [networking.defaultGateway6.source](#opt-networking.defaultGateway6.source). - Potential race conditions in the network setup when using `networking.interfaces` have been fixed by disabling duplicate address detection (DAD) for statically configured IPv6 addresses. - `strongSwan` has been updated to 6.0. See [strongSwan 6.0.0 release notes](https://github.com/strongswan/strongswan/releases/tag/6.0.0) for a complete list of changes. - `slurm` no longer supports gtk2. - `amdgpu` kernel driver overdrive mode can now be enabled by setting [hardware.amdgpu.overdrive.enable](#opt-hardware.amdgpu.overdrive.enable) and customized through [hardware.amdgpu.overdrive.ppfeaturemask](#opt-hardware.amdgpu.overdrive.ppfeaturemask). This allows for fine-grained control over the GPU's performance and maybe required by overclocking softwares like Corectrl and Lact. These new options replace old options such as {option}`programs.corectrl.gpuOverclock.enable` and {option}`programs.tuxclocker.enableAMD`. - `services.varnish.http_address` has been superseeded by `services.varnish.listen` which is now structured config for all of varnish's `-a` variations. - `services.nginx.recommendedProxySettings` now sets `X-Forwarded-Server` to the hostname of nginx instead of the original host. - [](#opt-services.gnome.gnome-keyring.enable) does not ship with an SSH agent anymore, as this is now handled by the `gcr_4` package instead of `gnome-keyring`. A new module has been added to support this, under [](#opt-services.gnome.gcr-ssh-agent.enable) (its default value has been set to [](#opt-services.gnome.gnome-keyring.enable) to ensure a smooth transition). See the [relevant upstream PR](https://gitlab.gnome.org/GNOME/gcr/-/merge_requests/67) for more details. - The `nettools` package (ifconfig, arp, mii-tool, netstat, route) is not installed by default anymore. The suite is unmaintained and users should migrate to `iproute2` and `ethtool` instead. - `sparkleshare` has been removed as it no longer builds and has been abandoned upstream. - The `open-webui` package's postgres support have been moved to optional dependencies to comply with upstream changes in 0.6.26. - `prl-tools` has been moved out of `linuxPackages` because Parallels Guest Tools become driverless since 26.1.0. - `services.opentelemetry-collector` has a new option `validateConfigFile` option that checks the configuration file during build. It is enabled by default if the configuration file is in the Nix store.
