5<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->
6
7- `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.
8
9- `rEFInd`, a graphical boot manager for UEFI systems, can now be used through [](#opt-boot.loader.refind.enable).
10
11- 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.
12
13- The default PostgreSQL version for new NixOS installations (i.e. with `system.stateVersion >= 25.11`) is v17.
14
15- 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;`.
16
17- 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).
18
19- 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`.
20
21- Syncthing has been updated to version 2.0.0.
22
23- 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.

145## Backward Incompatibilities {#sec-release-25.11-incompatibilities}
146
147<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->
148
149- The Perl implementation of the `switch-to-configuration` program is removed. 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.
150
151- The `no-broken-symlink` build hook now also fails builds whose output derivation contains links to $TMPDIR (typically /build, which contains the build directory).
152
153- The `services.polipo` module has been removed as `polipo` is unmaintained and archived upstream.
154
155- `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.
156
157- 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/)
158 for all the details and how to ensure smooth upgrades.
159
160- `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.
161 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.
162
163- 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/).
164
165- `services.seafile` has been removed, as it is unmaintained and outdated.
166 See [the manual](https://manual.seafile.com/13.0/upgrade/upgrade_notes_for_13.0.x/#important-release-changes)
167 for details and next steps.
168
169- 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.
170
171- []{#sec-release-25.11-incompatibilities-sourcehut-removed} The `services.sourcehut` module and corresponding `sourcehut` packages were removed due to being broken and unmaintained.
172- The zookeeper project changed their logging tool to logback, therefore `services.zookeeper.logging` option has been updated to expect a logback compatible string.
173- 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.
174
175- Configurations with `boot.initrd.systend.enable && !boot.initrd.enable` will have their `init` script at `$toplevel/init` instead of `$toplevel/prepare-root`. This is because it does not make sense for systemd stage 1 to affect the `init` script when stage 1 is entirely disabled (e.g. containers).
176
177- `programs.goldwarden` has been removed, due to the software not working with newer versions of the Bitwarden and Vaultwarden servers, as well as it being abandoned upstream.
178
179- The `cardboard` package and `programs.cardboard` module were removed due to the package having been broken since at least November 2024.
180
181- The default `kops` version is now 1.33.0 and versions 1.30 and older have been dropped. See [Upgrading Kubernetes](https://kops.sigs.k8s.io/tutorial/upgrading-kubernetes/) for instructions on how to update kOps.
182
183- `programs.skim.fuzzyCompletions` has been removed in favor of adding the completions to the package itself.
184
185- `Prosody` has been updated to major release 13 which removed some obsoleted modules and brought a couple of major and breaking changes:
186 - The `http_files` module is now disabled by default because it now requires `http_files_dir` to be configured.
187 - The `vcard_muc` module has been removed and got replaced by the inbuilt `muc_vcard` module.
188 - The `http_upload` module has been removed and you must migrate to the `http_file_share` module to stay XEP-0423 compliant. The `httpFileShare` options got expanded to better facility that.
189 - The `admin_shell` module is now always being loaded to make `prosodyctl` functional.
190 - The `mime_types_file` setting is now set to `"${pkgs.mailcap}/etc/mime.types"` to prevent errors.
191 For a complete list of changes, please see [their announcement](https://blog.prosody.im/prosody-13.0.0-released/).
192
193- The `yeahwm` package and `services.xserver.windowManager.yeahwm` module were removed due to the package being broken and unmaintained upstream.
194
195- 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.
196
197- 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.
198
199- 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.
200
201- The `services.siproxd` module has been removed as `siproxd` is unmaintained and broken with libosip 5.x.
202
203- `services.tor.torsocks.enable` no longer defaults to true if Tor and Tor client functionality is enabled.
204
205- `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`
206
207- `services.gateone` has been removed as the package was removed such that it does not work.
208
209- `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.
210
211- `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.
212 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.
213
214- `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.
215
216- The "NIXOS_EXTRA_MODULE_PATH" variable from configuration evaluation has been deprecated.
217 We recommend a workflow where you update the expression files instead, but if you wish to continue
218 to use this variable, you may do so with a module like:
219
220 ```nix
221 {
222 imports = [
223 (builtins.getEnv "NIXOS_EXTRA_MODULE_PATH")
224 ];
225 }
226 ```
227
228 This has the benefit that your configuration hints at the non-standard workflow.
229
230- `i18n.inputMethod.fcitx5.plasma6Support` has been removed because qt6 is the only one used for fcitx5-configtool now.
231
232- The `boot.readOnlyNixStore` has been removed. Control over bind mount options on `/nix/store` is now offered by the `boot.nixStoreMountOpts` option.
233
234- The Postfix module has been updated and likely requires configuration changes:
235 - The `services.postfix.sslCert` and `sslKey` options were removed and you now need to configure
236 - [services.postfix.settings.main.smtpd_tls_chain_files](#opt-services.postfix.settings.main.smtpd_tls_chain_files) for server certificates,
237 - [services.postfix.settings.main.smtp_tls_chain_files](#opt-services.postfix.settings.main) for client certificates.
238
239- `vmalert` now supports multiple instances with the option `services.vmalert.instances."".enable`
240
241- [`services.victorialogs.package`](#opt-services.victorialogs.package) now defaults to `victorialogs`, as `victoriametrics` no longer contains the VictoriaLogs binaries.
242
243- 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`.
244
245- The `wstunnel` module was converted to RFC42-style settings, you will need to update your NixOS config if you make use of this module.
246
247- [private-gpt](https://github.com/zylon-ai/private-gpt) service has been removed by lack of maintenance upstream.
248
249- 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`.
250
251- `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`.
252
253- `command-not-found` package is now disabled by default; it works only for nix-channels based systems, and requires setup for it to work.
254
255- 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.
256
257## Other Notable Changes {#sec-release-25.11-notable-changes}
258
259<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->
260
261- `services.clamsmtp` is unmaintained and was removed from Nixpkgs.
262
263- `services.eris-server` was removed from Nixpkgs due to a hostile upstream.
264
265- `prosody` gained a config check option named `services.prosody.checkConfig` which runs `prosodyctl check config` and is turned on by default.
266
267- `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`.
268
269- `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.
270
271- `services.dnscrypt-proxy` gains a `package` option to specify dnscrypt-proxy package to use.
272
273- `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.
274
275- 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.
276
277- 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.
278
279- `bcachefs` file systems will now use the out-of-tree module for supported kernels. The in-tree module is unmaintained and users are strongly recommended to switch to kernels that support the out-of-tree module.
280
281- `services.gitea` supports sending notifications with sendmail again. To do this, activate the parameter `services.gitea.mailerUseSendmail` and configure SMTP server.
282
283- `networking.wireless.networks.<name>` now has an option to specify SSID, hence allowing duplicated SSID setup. The BSSID option is added along side with this.
284
285- Revamp of the ACME certificate acquisication and renewal process to help scale systems with lots (100+) of certificates.
286
287 Units and targets have been reshaped to better support more specific dependency propagation and avoid
288 superfluously triggering unchanged units:
289
290 If a service requires a syntactically valid certificate to start it should now depend on the `acme-{certname}.service` unit.
291
292 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.
293
294 Instead of the previous `acme-finished-{certname}.target`s there are now `acme-order-renew-{certname}.service`s that will be activated
295 in a delayed fashion to ensure that bootstrapping with servers like nginx that take part in the acquisition/renewal process works
296 smoothly. Dependencies on `acme-finished` units should move to `acme-order-renew`.
297
298 Note that system activation will complete before all certificates may have been renewed or acquired.
299
300- `libvirt` now supports using `nftables` backend.
301 - The `virtualisation.libvirtd.firewallBackend` option can be used to configure the firewall backend used by libvirtd.
302
303- The third-party `ant-contrib` is no longer included in the `ant` package.
304
305- `systemd.extraConfig` and `boot.initrd.systemd.extraConfig` was converted to RFC42-style `systemd.settings.Manager` and `boot.initrd.systemd.settings.Manager` respectively.
306 - `systemd.watchdog.runtimeTime` was renamed to `systemd.settings.Manager.RuntimeWatchdogSec`
307 - `systemd.watchdog.device` was renamed to `systemd.settings.Manager.WatchdogDevice`
308 - `systemd.watchdog.rebootTime` was renamed to `systemd.settings.Manager.RebootWatchdogSec`
309 - `systemd.watchdog.kexecTime` was renamed to `systemd.settings.Manager.KExecWatchdogSec`
310 - `systemd.enableCgroupAccounting` was removed. Cgroup accounting now needs to be disabled directly using `systemd.settings.Manager.*Accounting`.
311
312- `services.logind.extraConfig` was converted to RFC42-style `services.logind.settings.Login`.
313
314- `services.ntpd-rs` now performs configuration validation.
315
316- 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)
317
318- `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.
319
320- `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.
321
322- `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.
323
324- `services.monero` now includes the `environmentFile` option for adding secrets to the Monero daemon config.
325
326- `services.netbird.server` now uses dedicated packages split out due to relicensing of server components to AGPLv3 with version `0.53.0`,
327
328- `services.pds` has been renamed to `services.bluesky-pds`.
329
330- `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.
331
332- The new option [networking.ipips](#opt-networking.ipips) has been added to create IP within IP kind of tunnels (including 4in6, ip6ip6 and ipip).
333 With the existing [networking.sits](#opt-networking.sits) option (6in4), it is now possible to create all combinations of IPv4 and IPv6 encapsulation.
334
335- It is now possible to configure the default source address using the new options [networking.defaultGateway.source](#opt-networking.defaultGateway.source),
336 [networking.defaultGateway6.source](#opt-networking.defaultGateway6.source).
337
338- Potential race conditions in the network setup when using `networking.interfaces` have been fixed by disabling duplicate address detection (DAD)
339 for statically configured IPv6 addresses.
340
341- `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.
342
343- `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).
344 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`.
345
346- `services.varnish.http_address` has been superseeded by `services.varnish.listen` which is now
347 structured config for all of varnish's `-a` variations.
348
349- `services.nginx.recommendedProxySettings` now sets `X-Forwarded-Server` to the hostname of nginx instead of the original host.
350
351- [](#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.
352
353- 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.
354
355- `sparkleshare` has been removed as it no longer builds and has been abandoned upstream.
356
357- The `open-webui` package's postgres support have been moved to optional dependencies to comply with upstream changes in 0.6.26.
