1# Release 23.11 (“Tapir”, 2023.11/29) {#sec-release-23.11}
2
3The NixOS release team is happy to announce a new version of NixOS. The release is called NixOS 23.11 ("Tapir").
4
5NixOS is a Linux distribution, whose set of packages can also be used on other Linux systems and macOS.
6
7Support is planned until the end of June 2024, handing over to NixOS 24.05.
8
9To upgrade to the latest release, follow the upgrade chapter and check the [Breaking Changes](#sec-release-23.11-nixos-breaking-changes)
10section for packages and services used in your configuration.
11
12The team is excited about the many software updates and improvements in this release. Just to name a few, do check the updates
13for `GNOME` packages, `systemd`, `glibc`, the `ROCM` package set, and `hostapd` (which brings support for WiFi6 (IEEE 802.11ax) and WPA3-SAE-PK).
14
15Make sure to also check the many updates in the [Nixpkgs library](#sec-release-23.11-nixpkgs-lib) when developing your own packages.

31### Breaking Changes {#sec-release-23.11-nixos-breaking-changes}
32
33- `services.postgresql.ensurePermissions` has been deprecated in favor of
34 `services.postgresql.ensureUsers.*.ensureDBOwnership` which simplifies the
35 setup of database owned by a certain system user in local database contexts
36 (which make use of peer authentication via UNIX sockets), migration
37 guidelines were provided in the NixOS manual, please refer to them if you are
38 affected by a PostgreSQL 15 changing the way `GRANT ALL PRIVILEGES` is
39 working. `services.postgresql.ensurePermissions` will be removed in 24.05.
40 All NixOS modules were migrated using one of the strategy, e.g.
41 `ensureDBOwnership` or `postStart`. Refer to the [PR
42 #266270](https://github.com/NixOS/nixpkgs/pull/266270) for more details.
43
44- `network-online.target` has been fixed to no longer time out for systems with
45 `networking.useDHCP = true` and `networking.useNetworkd = true`. Workarounds
46 for this can be removed.
47
48- The `boot.loader.raspberryPi` options have been marked deprecated, with
49 intent of removal for NixOS 24.11. They had a limited use-case, and do not
50 work like people expect. They required either very old installs from ([before
51 mid-2019](https://github.com/NixOS/nixpkgs/pull/62462)) or customized builds
52 out of scope of the standard and generic AArch64 support. That option set
53 never supported the Raspberry Pi 4 family of devices.
54
55- `python3.pkgs.sequoia` was removed in favor of `python3.pkgs.pysequoia`. The
56 latter package is based on upstream's dedicated repository for sequoia's
57 Python bindings, where the Python bindings from
58 [gitlab:sequoia-pgp/sequoia](https://gitlab.com/sequoia-pgp/sequoia) were
59 removed long ago.
60
61- `writeTextFile` requires `executable` to be boolean now, values like `null`
62 or `""` will fail to evaluate now.
63
64- The latest version of `clonehero` now stores custom content in
65 `~/.clonehero`. Refer to the [migration
66 instructions](https://clonehero.net/2022/11/29/v23-to-v1-migration-instructions.html)
67 for more details. Typically, these content files would exist along side the
68 binary, but the previous build used a wrapper script that would store them in
69 `~/.config/unity3d/srylain Inc_/Clone Hero`.
70
71- `services.mastodon` doesn't support providing a TCP port to its `streaming`
72 component anymore, as upstream implemented parallelization by running
73 multiple instances instead of running multiple processes in one instance.
74 Please create a PR if you are interested in this feature.\
75 Due to this, the desired number of such instances
76 {option}`services.mastodon.streamingProcesses` now needs to be declared explicitly.
77
78- The `services.hostapd` module was rewritten to support `passwordFile` like
79 options, WPA3-SAE, and management of multiple interfaces. This breaks
80 compatibility with older configurations.
81 - `hostapd` is now started with additional systemd sandbox/hardening options
82 for better security.
83 - `services.hostapd.interface` was replaced with a per-radio and per-bss
84 configuration scheme using
85 [services.hostapd.radios](#opt-services.hostapd.radios).
86 - `services.hostapd.wpa` has been replaced by
87 [services.hostapd.radios.<name>.networks.<name>.authentication.wpaPassword](#opt-services.hostapd.radios._name_.networks._name_.authentication.wpaPassword)
88 and
89 [services.hostapd.radios.<name>.networks.<name>.authentication.saePasswords](#opt-services.hostapd.radios._name_.networks._name_.authentication.saePasswords)
90 which configure WPA2-PSK and WP3-SAE respectively.
91 - The default authentication has been changed to WPA3-SAE. Options for other
92 (legacy) schemes are still available.
93
94- `python3.pkgs.fetchPypi` and `python3Packages.fetchPypi` have been
95 deprecated in favor of top-level `fetchPypi`.
96
97- xdg-desktop-portal has been updated to 1.18, which reworked how portal
98 implementations are selected. If you roll your own desktop environment, you
99 should either set `xdg.portal.config` or `xdg.portal.configPackages`, which
100 allow fine-grained control over which portal backend to use for specific
101 interfaces, as described in {manpage}`portals.conf(5)`.
102
103 If you don't provide configurations, a portal backend will only be considered
104 when the desktop you use matches its deprecated `UseIn` key. While some NixOS
105 desktop modules should already ship one for you, it is suggested to test
106 portal availability by trying [Door
107 Knocker](https://flathub.org/apps/xyz.tytanium.DoorKnocker) and [ASHPD
108 Demo](https://flathub.org/apps/com.belmoussaoui.ashpd.demo). If things
109 regressed, you may run `G_MESSAGES_DEBUG=all
110 /path/to/xdg-desktop-portal/libexec/xdg-desktop-portal` for ideas on which
111 config file and which portals are chosen.
112
113- `pass` now does not contain `password-store.el`. Users should get
114 `password-store.el` from Emacs lisp package set `emacs.pkgs.password-store`.
115
116- `services.knot` now supports `.settings` from RFC42. The previous
117 `.extraConfig` still works the same, but it displays a warning now.
118
119- `services.invoiceplane` now supports `.settings` from RFC42. The previous
120 `.extraConfig` still works the same way, but it displays a warning now.
121
122- `mu` does not install `mu4e` files by default now. Users should get `mu4e`
123 from Emacs lisp package set `emacs.pkgs.mu4e`.
124
125- `mariadb` now defaults to `mariadb_1011` instead of `mariadb_106`, meaning
126 the default version was upgraded from v10.6.x to v10.11.x. Refer to the
127 [upgrade
128 notes](https://mariadb.com/kb/en/upgrading-from-mariadb-10-6-to-mariadb-10-11/)
129 for potential issues.
130
131- `getent` has been moved from `glibc`'s `bin` output to its own dedicated
132 output, reducing closure size for many dependents. Dependents using the
133 `getent` alias should not be affected; others should move from using
134 `glibc.bin` or `getBin glibc` to `getent` (which also improves compatibility
135 with non-glibc platforms).
136
137- `maintainers/scripts/update-luarocks-packages` is now a proper package
138 `luarocks-packages-updater` that can be run to maintain out-of-tree luarocks
139 packages.
140
141- The `users.users.<name>.passwordFile` has been renamed to
142 `users.users.<name>.hashedPasswordFile` to avoid possible confusions. The
143 option is in fact the file-based version of `hashedPassword`, not `password`,
144 and expects a file containing the {manpage}`crypt(3)` hash of the user
145 password.
146
147- `chromiumBeta` and `chromiumDev` have been removed due to the lack of
148 maintenance in nixpkgs. Consider using `chromium` instead.
149
150- `google-chrome-beta` and `google-chrome-dev` have been removed due to the
151 lack of maintenance in nixpkgs. Consider using `google-chrome` instead.
152
153- The `services.ananicy.extraRules` option now has the type of `listOf attrs`
154 instead of `string`.
155
156- `buildVimPluginFrom2Nix` has been renamed to `buildVimPlugin`, which now
157 now skips `configurePhase` and `buildPhase`.
158
159- JACK tools (`jack_*` except `jack_control`) have moved from the `jack2`
160 package to `jack-example-tools`.
161
162- The `waagent` service does provisioning now.
163
164- The `matrix-synapse` package & module have undergone some significant
165 internal changes, for most setups no intervention is needed, though:
166 - The option
167 [`services.matrix-synapse.package`](#opt-services.matrix-synapse.package)
168 is read-only now. For modifying the package, use an overlay which modifies
169 `matrix-synapse-unwrapped` instead. More on that below.
170 - The `enableSystemd` & `enableRedis` arguments have been removed and
171 `matrix-synapse` has been renamed to `matrix-synapse-unwrapped`. Also,
172 several optional dependencies (such as `psycopg2` or `authlib`) have been
173 removed.
174 - These optional dependencies are automatically added via a wrapper
175 (`pkgs.matrix-synapse.override { extras = ["redis"]; }` for `hiredis` &
176 `txredisapi` for instance) if the relevant config section is declared in
177 `services.matrix-synapse.settings`. For instance, if
178 `services.matrix-synapse.settings.redis.enabled` is set to `true`,
179 `"redis"` will be automatically added to the `extras` list of
180 `pkgs.matrix-synapse`.
181 - A list of all extras (and the extras enabled by default) can be found at
182 the [option's reference for
183 `services.matrix-synapse.extras`](#opt-services.matrix-synapse.extras).
184 - In some cases (e.g. for running synapse workers) it was necessary to re-use
185 the `PYTHONPATH` of `matrix-synapse.service`'s environment to have all
186 plugins available. This isn't necessary anymore, instead
187 `config.services.matrix-synapse.package` can be used as it points to the
188 wrapper with properly configured `extras` and also all plugins defined via
189 [`services.matrix-synapse.plugins`](#opt-services.matrix-synapse.plugins)
190 available. This is also the reason for why the option is read-only now,
191 it's supposed to be set by the module only.
192
193- `netbox` was updated to v3.6. `services.netbox.package` still defaults
194 to v3.5 if `stateVersion` is earlier than 23.11. Refer to upstream's breaking
195 changes [for
196 v3.6.0](https://github.com/netbox-community/netbox/releases/tag/v3.6.0) and
197 upgrade NetBox by changing `services.netbox.package`. Database migrations
198 will be run automatically.
199
200- `etcd` has been updated to v3.5. Refer to upgrade guides for [v3.3 to
201 v3.4](https://etcd.io/docs/v3.5/upgrades/upgrade_3_4/) and [v3.4 to
202 v3.5](https://etcd.io/docs/v3.5/upgrades/upgrade_3_5/) for more details.
203
204- `gitlab` installations created or updated between versions \[15.11.0,
205 15.11.2] have an incorrect database schema. This will become a problem when
206 upgrading to `gitlab` >=16.2.0. A workaround for affected users can be found
207 in the [GitLab
208 docs](https://docs.gitlab.com/ee/update/versions/gitlab_16_changes.html#undefined-column-error-upgrading-to-162-or-later).
209
210
211- `consul` has been updated to v1.16.0. Refer to the [release
212 note](https://github.com/hashicorp/consul/releases/tag/v1.16.0) for more
213 details. Once a new Consul version has started and upgraded it's data
214 directory, it generally cannot be downgraded to the previous version.
215
216- `llvmPackages_rocm` has been moved to `rocmPackages.llvm`.
217
218- `hip`, `rocm-opencl-runtime`, `rocm-opencl-icd`, and `rocclr` have been
219 combined into `rocmPackages.clr`.
220
221- `clang-ocl`, `clr`, `composable_kernel`, `hipblas`, `hipcc`, `hip-common`, `hipcub`,
222 `hipfft`, `hipfort`, `hipify`, `hipsolver`, `hipsparse`, `migraphx`, `miopen`, `miopengemm`,
223 `rccl`, `rdc`, `rocalution`, `rocblas`, `rocdgbapi`, `rocfft`, `rocgdb`, `rocm-cmake`,
224 `rocm-comgr`, `rocm-core`, `rocm-device-libs`, `rocminfo`, `rocmlir`, `rocm-runtime`,
225 `rocm-smi`, `rocm-thunk`, `rocprim`, `rocprofiler`, `rocrand`, `rocr-debug-agent`,
226 `rocsolver`, `rocsparse`, `rocthrust`, `roctracer`, `rocwmma`, and `tensile`
227 have been moved to `rocmPackages`.
228
229- `himalaya` has been updated to v0.8.0, which drops the native TLS support
230 (in favor of Rustls) and add OAuth 2.0 support. Refer to the [release
231 note](https://github.com/soywod/himalaya/releases/tag/v0.8.0) for more
232 details.
233
234
235- `nix-prefetch-git` now ignores global and user git config, to improve
236 reproducibility.
237
238- The [services.caddy.acmeCA](#opt-services.caddy.acmeCA) option defaults
239 to `null` instead of `"https://acme-v02.api.letsencrypt.org/directory"` now.
240 To use all of Caddy's default ACME CAs and enable Caddy's automatic issuer
241 fallback feature by default, as recommended by upstream.
242
243- The default priorities of
244 [`services.nextcloud.phpOptions`](#opt-services.nextcloud.phpOptions) have
245 changed. This means that e.g.
246 `services.nextcloud.phpOptions."opcache.interned_strings_buffer" = "23";`
247 doesn't discard all of the other defaults from this option anymore. The
248 attribute values of `phpOptions` are still defaults, these can be overridden
249 as shown here.
250
251 To override all of the options (including including `upload_max_filesize`,
252 `post_max_size` and `memory_limit` which all point to
253 [`services.nextcloud.maxUploadSize`](#opt-services.nextcloud.maxUploadSize)
254 by default) can be done like this:
255
256 ```nix
257 {
258 services.nextcloud.phpOptions = lib.mkForce {
259 # ...
260 };
261 }
262 ```
263
264- `php80` is no longer supported due to upstream not supporting this version
265 anymore.
266
267- PHP defaults to PHP 8.2 now, updated from v8.1.
268
269- GraalVM has been updated to the latest version, and this brings significant
270 changes. Upstream don't release multiple versions targeting different JVMs
271 anymore, so now we only have one GraalVM derivation (`graalvm-ce`). While at
272 first glance the version may seem a downgrade (v22.3.1 -> v21.0.0), the major
273 version is now following the JVM it targets (so this latest version targets
274 JVM 21). Also some products like `llvm-installable-svm` and
275 `native-image-svm` were incorporate to the main GraalVM derivation, so
276 they're included by default.
277
278- GraalPy (`graalCEPackages.graalpy`), TruffleRuby
279 (`graalCEPackages.truffleruby`), GraalJS (`graalCEPackages.graaljs`) and
280 GraalNodeJS (`grallCEPackages.graalnodejs`) are now independent from the main
281 GraalVM derivation.
282
283- The ISC DHCP package and corresponding module have been removed, because they
284 are EOL upstream. Refer [to this
285 post](https://www.isc.org/blogs/isc-dhcp-eol/) for details and switch to a
286 different DHCP implementation like kea or dnsmasq.
287
288- `prometheus-unbound-exporter` has been replaced by the Let's Encrypt
289 maintained version, since the previous version was archived. This requires
290 some changes to the module configuration, most notable `controlInterface`
291 needs migration towards `unbound.host` and requires either the `tcp://` or
292 `unix://` URI scheme.
293
294- `odoo` defaults to v16 now, updated from v15.
295
296- `varnish` was upgraded from v7.2.x to v7.4.x. Refer to upgrade guides vor
297 [v7.3](https://varnish-cache.org/docs/7.3/whats-new/upgrading-7.3.html) and
298 [v7.4](https://varnish-cache.org/docs/7.4/whats-new/upgrading-7.4.html). The
299 current LTS version is still offered as `varnish60`.
300
301- `util-linux` is now supported on Darwin and is no longer an alias to
302 `unixtools`. Use the `unixtools.util-linux` package for access to the Apple
303 variants of the utilities.
304
305- `services.keyd` changed API. Now you can create multiple configuration files.
306
307- `baloo`, the file indexer and search engine used by KDE now has a patch to
308 prevent files from constantly being reindexed when the device IDs of the
309 their underlying storage change. This happens frequently when using btrfs or
310 LVM. The patch has not yet been accepted upstream but it provides a
311 significantly improved experience. When upgrading, reset baloo to get a clean
312 index: `balooctl disable ; balooctl purge ; balooctl enable`.
313
314- The `vlock` program from the `kbd` package has been moved into its own
315 package output and should now be referenced explicitly as `kbd.vlock` or
316 replaced with an alternative such as the standalone `vlock` package or
317 `physlock`.
318
319- `fileSystems.<name>.autoFormat` now uses `systemd-makefs`, which does not
320 accept formatting options. Therefore, `fileSystems.<name>.formatOptions` has
321 been removed.
322
323- `fileSystems.<name>.autoResize` uses `systemd-growfs` to resize the file
324 system online in Stage 2 now. This means that `f2fs` and `ext2` can no longer
325 be auto resized, while `xfs` and `btrfs` now can be.
326
327- `fuse3` has been updated from v3.11.0 to v3.16.2. Refer to the
328 [changelog](https://github.com/libfuse/libfuse/blob/fuse-3.16.2/ChangeLog.rst#libfuse-3162-2023-10-10)
329 for an overview of the changes.
330
331 Unsupported mount options are no longer silently accepted [(since
332 3.15.0)](https://github.com/libfuse/libfuse/blob/fuse-3.16.2/ChangeLog.rst#libfuse-3150-2023-06-09).
333 The [affected mount
334 options](https://github.com/libfuse/libfuse/commit/dba6b3983af34f30de01cf532dff0b66f0ed6045)
335 are: `atime`, `diratime`, `lazytime`, `nolazytime`, `relatime`, `norelatime`,
336 `strictatime`.
337
338 For example,
339
340 ```bash
341 $ sshfs 127.0.0.1:/home/test/testdir /home/test/sshfs_mnt -o atime
342 ```
343
344 would previously terminate successfully with the mount point established, now
345 it outputs the error message ``fuse: unknown option(s): `-o atime'`` and
346 terminates with exit status 1.
347
348- `nixos-rebuild {switch,boot,test,dry-activate}` runs the system
349 activation inside `systemd-run` now, creating an ephemeral systemd service
350 and protecting the system switch against issues like network disconnections
351 during remote (e.g. SSH) sessions. This has the side effect of running the
352 switch in an isolated environment, that could possible break post-switch
353 scripts that depends on things like environment variables being set. If you
354 want to opt-out from this behavior for now, you may set the
355 `NIXOS_SWITCH_USE_DIRTY_ENV` environment variable before running
356 `nixos-rebuild`. However, keep in mind that this option will be removed in
357 the future.
358
359- The `services.vaultwarden.config` option default value was changed to make
360 Vaultwarden only listen on localhost, following the [secure defaults for most
361 NixOS services](https://github.com/NixOS/nixpkgs/issues/100192).
362
363- `services.lemmy.settings.federation` was removed in v0.17.0 and no longer has
364 any effect. To enable federation, the hostname must be set in the
365 configuration file and then federation must be enabled in the admin web UI.
366 Refer to the [release
367 notes](https://github.com/LemmyNet/lemmy/blob/c32585b03429f0f76d1e4ff738786321a0a9df98/RELEASES.md#upgrade-instructions)
368 for more details.
369
370- `pict-rs` was upgraded from v0.3 to v0.4 and contains an incompatible database
371 & configuration change. To upgrade on systems with `stateVersion = "23.05";`
372 or older follow the migration steps from
373 https://git.asonix.dog/asonix/pict-rs#user-content-0-3-to-0-4-migration-guide
374 and set `services.pict-rs.package = pkgs.pict-rs;`.
375
376- The following packages in `haskellPackages` have a separate bin output now:
377 `cabal-fmt`, `calligraphy`, `eventlog2html`, `ghc-debug-brick`, `hindent`,
378 `nixfmt`, `releaser`. This means you need to replace e.g.
379 `"${pkgs.haskellPackages.nixfmt}/bin/nixfmt"` with `"${lib.getBin
380 pkgs.haskellPackages.nixfmt}/bin/nixfmt"` or `"${lib.getExe
381 pkgs.haskellPackages.nixfmt}"`. The binaries also won’t be in scope if you
382 rely on them being installed e.g. via `ghcWithPackages`.
383 `environment.packages` picks the `bin` output automatically, so for normal
384 installation no intervention is required. Also, toplevel attributes like
385 `pkgs.nixfmt` are not impacted negatively by this change.
386
387- `spamassassin` no longer supports the `Hashcash` module. The module needs to
388 be removed from the `loadplugin` list if it was copied over from the default
389 `initPreConf` option.
390
391- `nano` was removed from `environment.defaultPackages`. To not leave systems
392 without a editor, now `programs.nano.enable` is enabled by default.
393
394- `programs.nano.nanorc` and `programs.nano.syntaxHighlight` no longer have an
395 effect unless `programs.nano.enable` is set to true which is the default.
396
397- `services.outline.sequelizeArguments` has been removed, as `outline` no
398 longer executes database migrations via the `sequelize` cli.
399
400- The binary of the package `cloud-sql-proxy` has changed from
401 `cloud_sql_proxy` to `cloud-sql-proxy`.
402
403- The module `services.apache-kafka` was largely rewritten and has certain
404 breaking changes. To be precise, this means that the following things have
405 changed:
406 - Most settings have been migrated to
407 [services.apache-kafka.settings](#opt-services.apache-kafka.settings).
408 - Care must be taken when adapting an existing cluster to these changes,
409 see [](#module-services-apache-kafka-migrating-to-settings).
410 - By virtue of being less opinionated, it is now possible to use the module
411 to run Apache Kafka in KRaft mode instead of Zookeeper mode.
412 - [A few options](#module-services-apache-kafka-kraft) have been added to
413 assist in this mode.
414
415- Garage has been upgraded to v0.9.x. `services.garage.package` needs to be
416 explicitly set now, so version upgrades can be done in a controlled fashion.
417 For this, we expose `garage_x_y` attributes which can be set here.
418
419- `voms` and `xrootd` now moves the `$out/etc` content to the `$etc` output
420 instead of `$out/etc.orig`, when input argument `externalEtc` is not `null`.
421
422- The `woodpecker-*` CI packages have been updated to v1.0.0. This release is
423 wildly incompatible with the v0.15.x versions that were previously packaged.
424 Refer to [upstream's
425 documentation](https://woodpecker-ci.org/docs/next/migrations#100) to learn
426 how to update your CI configurations.
427
428- Meilisearch was updated from v1.3.1 to v1.5.0. The update has breaking
429 changes about backslashes and filtering. Refer to the [release
430 announcement](https://blog.meilisearch.com/v1-4-release/) for more
431 details.
432
433- The Caddy module gained a new option named `services.caddy.enableReload`
434 which is enabled by default. It allows reloading the service instead of
435 restarting it, if only a config file has changed. This option must be
436 disabled if you have turned off the [Caddy admin
437 API](https://caddyserver.com/docs/caddyfile/options#admin). If you keep this
438 option enabled, you should consider setting
439 [`grace_period`](https://caddyserver.com/docs/caddyfile/options#grace-period)
440 to a non-infinite value to prevent Caddy from delaying the reload
441 indefinitely.
442
443- mdraid support is optional now. This reduces initramfs size and prevents the
444 potentially undesired automatic detection and activation of software RAID
445 pools. It is disabled by default in new configurations (determined by
446 `stateVersion`), but the appropriate settings will be generated by
447 `nixos-generate-config` when installing to a software RAID device, so the
448 standard installation procedure should be unaffected. If you have custom
449 configs relying on mdraid, ensure that you use `stateVersion` correctly or
450 set `boot.swraid.enable` manually. On systems with an updated `stateVersion`
451 we now also emit warnings if `mdadm.conf` does not contain the minimum
452 required configuration necessary to run the dynamically enabled monitoring
453 daemons.
454
455- The `go-ethereum` package has been updated to v1.12.0. This drops support for
456 proof-of-work. Its GraphQL API now encodes all numeric values as hex strings
457 and the GraphQL UI is updated to v2.0. The default database has changed from
458 `leveldb` to `pebble` but `leveldb` can be forced with the
459 --db.engine=leveldb flag. The `checkpoint-admin` command was [removed along
460 with trusted
461 checkpoints](https://github.com/ethereum/go-ethereum/pull/27147).
462
463- The `aseprite-unfree` package has been upgraded from v1.2.16.3 to v1.2.40.
464 The free version of aseprite has been dropped because it is EOL and the
465 package attribute now points to the unfree version. A maintained fork of the
466 last free version of Aseprite, named 'LibreSprite', is available in the
467 `libresprite` package.
468
469- The default `kops` version is v1.28.0 now and support for v1.25 and older have
470 been dropped.
471
472- `pharo` has been updated to latest stable v10.0.8, which is compatible with
473 the latest stable and oldstable images (Pharo 10 and 11). The VM in question
474 is the 64bit Spur. The 32bit version has been dropped due to lack of
475 maintenance. The Cog VM has been deleted because it is severely outdated.
476 Finally, the `pharo-launcher` package has been deleted because it was not
477 compatible with the newer VM, and due to lack of maintenance.
478
479- Emacs mainline v29 was introduced. This new version includes many major
480 additions, most notably `tree-sitter` support (enabled by default) and
481 the pgtk variant (useful for Wayland users), which is available under the
482 attribute `emacs29-pgtk`.
483
484- Emacs macport version 29 was introduced.
485
486- The option `services.networking.networkmanager.enableFccUnlock` was removed
487 in favor of `networking.networkmanager.fccUnlockScripts`, which allows
488 specifying unlock scripts explicitly. The previous option enabled all unlock
489 scripts bundled with ModemManager, which is risky, and didn't allow using
490 vendor-provided unlock scripts at all.
491
492- The `html-proofer` package has been updated from major version 3 to major
493 version 5, which includes [breaking
494 changes](https://github.com/gjtorikian/html-proofer/blob/v5.0.8/UPGRADING.md).
495
496- `kratos` has been updated from v0.10.1 to the first stable v1.0.0, please
497 read the [v0.10.1 to
498 v0.11.0](https://github.com/ory/kratos/releases/tag/v0.11.0), [v0.11.0 to
499 v0.11.1](https://github.com/ory/kratos/releases/tag/v0.11.1), [v0.11.1 to
500 v0.13.0](https://github.com/ory/kratos/releases/tag/v0.13.0) and [v0.13.0 to
501 v1.0.0](https://github.com/ory/kratos/releases/tag/v1.0.0) upgrade guides.
502 The most notable breaking change is the introduction of one-time passwords
503 (`code`) and update of the default recovery strategy from `link` to `code`.
504
505- The `hail` module was removed, as `hail` was unmaintained since 2017.
506
507- Package `noto-fonts-emoji` was renamed to `noto-fonts-color-emoji`. Refer to
508 [PR #221181](https://github.com/NixOS/nixpkgs/issues/221181) for more
509 details.
510
511- Package `cloud-sql-proxy` was renamed to `google-cloud-sql-proxy` as it
512 cannot be used with other cloud providers.
513
514- Package `pash` was removed due to being archived upstream. Use `powershell`
515 as an alternative.
516
517- The option `services.plausible.releaseCookiePath` has been removed. Plausible
518 does not use any distributed Erlang features, and does not plan to (refer to
519 [discussion](https://github.com/NixOS/nixpkgs/pull/130297#issuecomment-1805851333)),
520 Thus NixOS disables them now , and the Erlang cookie becomes unnecessary. You
521 may delete the file that `releaseCookiePath` was set to.
522
523- `security.sudo.extraRules` includes `root`'s default rule now, with ordering
524 priority 400. This is functionally identical for users not specifying rule
525 order, or relying on `mkBefore` and `mkAfter`, but may impact users calling
526 `mkOrder n` with n ≤ 400.
527
528- X keyboard extension (XKB) options have been reorganized into a single
529 attribute set, `services.xserver.xkb`. Specifically,
530 `services.xserver.layout` is `services.xserver.xkb.layout` now,
531 `services.xserver.extraLayouts` is `services.xserver.xkb.extraLayouts` now,
532 `services.xserver.xkbModel` is `services.xserver.xkb.model` now,
533 `services.xserver.xkbOptions` is `services.xserver.xkb.options` now ,
534 `services.xserver.xkbVariant` is `services.xserver.xkb.variant` now, and
535 `services.xserver.xkbDir` is `services.xserver.xkb.dir` now.
536
537- `networking.networkmanager.firewallBackend` was removed as NixOS is now using
538 iptables-nftables-compat even when using iptables, therefore Networkmanager
539 uses the nftables backend unconditionally now.
540
541- `rome` was removed because it is no longer maintained and is succeeded by
542 `biome`.
543
544- The `prometheus-knot-exporter` was migrated to a version maintained by
545 CZ.NIC. Various metric names have changed, so checking existing rules is
546 recommended.
547
548- The `services.mtr-exporter.target` has been removed in favor of
549 `services.mtr-exporter.jobs` which allows specifying multiple targets.
550
551- `blender-with-packages` has been deprecated in favor of
552 `blender.withPackages`, for example `blender.withPackages (ps: [ps.bpycv])`.
553 It behaves similarly to `python3.withPackages`.
554
555- Setting `nixpkgs.config` options while providing an external `pkgs` instance
556 will now raise an error instead of silently ignoring the options. NixOS
557 modules no longer set `nixpkgs.config` to accommodate this. This specifically
558 affects `services.locate`,
559 `services.xserver.displayManager.lightdm.greeters.tiny` and
560 `programs.firefox` NixOS modules. No manual intervention should be required
561 in most cases, however, configurations relying on those modules affecting
562 packages outside the system environment should switch to explicit overlays.
563
564- `privacyidea` (and the corresponding `privacyidea-ldap-proxy`) has been
565 removed from nixpkgs because it has severely outdated dependencies that
566 became unmaintainable with nixpkgs' python package-set.
567
568- `dagger` was removed because using a package called `dagger` and packaging it
569 from source violates their trademark policy.
570
571- `win-virtio` package was renamed to `virtio-win` to be consistent with the upstream package name.
572
573- `ps3netsrv` has been replaced with the webman-mod fork, the executable has
574 been renamed from `ps3netsrv++` to `ps3netsrv` and cli parameters have
575 changed.
576
577- `ssm-agent` package and module were renamed to `amazon-ssm-agent` to be
578 consistent with the upstream package name.
579
580- `services.kea.{ctrl-agent,dhcp-ddns,dhcp,dhcp6}` now use separate runtime
581 directories instead of `/run/kea` to work around the runtime directory being
582 cleared on service start.
583
584- `mkDerivation` rejects MD5 hashes now.
585
586- The `junicode` font package has been updated to [major
587 v2](https://github.com/psb1558/Junicode-font/releases/tag/v2.001), which is
588 a font family now. In particular, plain `Junicode.ttf` no longer exists. In
589 addition, TrueType font files are now placed in `font/truetype` instead of
590 `font/junicode-ttf`; this change does not affect use via `fonts.packages`
591 option.
592
593- The `prayer` package as well as `services.prayer` have been removed because
594 it's been unmaintained for several years and the author's website has
595 vanished.
596
597- The `chrony` NixOS module now tracks the real-time clock drift from the
598 system clock with `rtcfile` and automatically adjusts it with `rtcautotrim`
599 when it exceeds the maximum error specified in
600 `services.chrony.autotrimThreshold` (defaults to 30 seconds). If you enabled
601 `rtcsync` in `extraConfig`, you should remove RTC related options from
602 `extraConfig`. If you do not want chrony configured to keep the RTC in check,
603 you can set `services.chrony.enableRTCTrimming = false;`.
604
605- `trilium-desktop` and `trilium-server` have been updated to
606 [v0.61](https://github.com/zadam/trilium/releases/tag/v0.61.12). For existing
607 installations, upgrading to this version is supported only after running
608 v0.60.x at least once. If you are still on an older version, make sure to
609 update to v0.60 (available in NixOS 23.05) first and only then to v0.61
610 (available in NixOS 23.11).
611
612- Cassandra now defaults to v4.x, updated from v3.11.x.
613
614
615- FoundationDB now defaults to major version 7.
616
617- [glibc](https://www.gnu.org/software/libc/) has been updated from v2.37 to
618 v2.38. Refer to the [the release
619 notes](https://sourceware.org/glibc/wiki/Release/2.38) for more details.
620
621- `linuxPackages_testing_bcachefs` is now soft-deprecated by
622 `linuxPackages_testing`.
623 - Please consider changing your NixOS configuration's `boot.kernelPackages`
624 to `linuxPackages_testing` until a stable kernel with bcachefs support is
625 released.
626
627- PostgreSQL now defaults to major version 15.
628
629- All [ROCm](https://rocm.docs.amd.com/en/latest/) packages have been updated
630 to v5.7.0.
631 - [ROCm](https://rocm.docs.amd.com/en/latest/) package attribute sets are
632 versioned: `rocmPackages` -> `rocmPackages_5`.
633
634- [systemd](https://systemd.io) has been updated from v253 to v254, refer to
635 [the release
636 notes](https://github.com/systemd/systemd/blob/v254/NEWS#L3-L659) for more
637 details.
638 - `boot.resumeDevice` **must be specified** when hibernating if not in EFI
639 mode.
640 - systemd may warn your system about the permissions of your ESP partition
641 (often `/boot`), this warning can be ignored for now, we are looking into
642 a satisfying solution regarding this problem.
643 - Updating with `nixos-rebuild boot` and rebooting is recommended, since in
644 some rare cases the `nixos-rebuild switch` into the new generation on a
645 live system might fail due to missing mount units.
646
647- If the user has a custom shell enabled via `users.users.${USERNAME}.shell =
648 ${CUSTOMSHELL}`, the assertion will require them to also set
649 `programs.${CUSTOMSHELL}.enable = true`. This is generally safe behavior, but
650 for anyone needing to opt out from the check
651 `users.users.${USERNAME}.ignoreShellProgramCheck = true` will do the job.
652
653- `yarn-berry` has been updated to v4.0.1. This means that NodeJS versions less
654 v18.12 are no longer supported by it. Refer to the [upstream
655 changelog](https://github.com/yarnpkg/berry/blob/master/CHANGELOG.md) for
656 more details.
657
658- GNOME has been updated to v45. Refer to the [release
659 notes](https://release.gnome.org/45/) for more details. Notably, Loupe has
660 replaced Eye of GNOME as the default image viewer, Snapshot has replaced
661 Cheese as the default camera application, and Photos will no longer be
662 installed.
663
664- The module `services.ankisyncd` has been switched to
665 [anki-sync-server-rs](https://github.com/ankicommunity/anki-sync-server-rs).
666 The former version written in Python was difficult to update, did not receive
667 updates in a while, and did not support recent versions of Anki.
668
669 Unfortunately all servers supporting new clients do not support the older
670 sync protocol that was used in the old server. This includes newer version of
671 anki-sync-server, Anki's built in sync server and this new Rust package. Thus
672 old clients will also need updating. In particular nixpkgs's Anki package is
673 also being updated in this release.
674
675 The module update takes care of the new config syntax. The data itself (i.e.
676 user login and card information) is compatible. Thus users of the module will
677 be able to simply log in again after updating both client and server without
678 any extra action needed to be taken.
679
680- The argument `vendorSha256` of `buildGoModule` is deprecated. Use
681 `vendorHash` instead. Refer to [PR
682 \#259999](https://github.com/NixOS/nixpkgs/pull/259999)) for more details.
683
684- `go-modules` in `buildGoModule` attrs has been renamed to `goModules`.
685
686- The package `cawbird` is dropped from nixpkgs. It broke by the Twitter API
687 closing down and has been abandoned upstream.
688
689- The Cinnamon module now enables XDG desktop integration by default. If you
690 are experiencing collisions related to xdg-desktop-portal-gtk you can safely
691 remove `xdg.portal.extraPortals = [ pkgs.xdg-desktop-portal-gtk ];` from your
692 NixOS configuration.
693
694- GNOME, Pantheon, Cinnamon modules no longer force Qt applications to use
695 Adwaita style. This implemantion was buggy and is no longer maintained
696 upstream. Specifically, Cinnamon defaults to the gtk2 style instead now,
697 following the default in Linux Mint). If you still want Adwaita used, you may
698 add the following options to your configuration. Please be aware, that it
699 will probably be removed eventually.
700
701 ```nix
702 {
703 qt = {
704 enable = true;
705 platformTheme = "gnome";
706 style = "adwaita";
707 };
708 }
709 ```
710
711- DocBook option documentation is no longer supported, all module documentation
712 now uses Markdown.
713
714- Docker defaults to v24 now, as 20.10 is stopping to receive security updates
715 and bug fixes after [December 10,
716 2023](https://github.com/moby/moby/discussions/45104).
717
718- Elixir defaults to v1.15 now. Refer to their
719 [changelog](https://elixir-lang.org/blog/2023/06/19/elixir-v1-15-0-released/)
720 for more details.
721
722- The `extend` function of `llvmPackages` has been removed due it coming from
723 the `tools` attrset thus only extending the `tool` attrset. A possible
724 replacement is to construct the set from `libraries` and `tools`, or patch
725 nixpkgs.
726
727- `ffmpeg` defaults to `ffmpeg_6` now, upgrading from `ffmpeg_5`.
728
729- `fontconfig` defaults to using greyscale antialiasing now. Previously
730 subpixel antialiasing was used because of a [recommendation from one of the
731 downstreams](https://gitlab.freedesktop.org/fontconfig/fontconfig/-/issues/337).
732 You can change this value by configuring
733 [](#opt-fonts.fontconfig.subpixel.rgba) accordingly.
734
735- The `fonts.fonts` and `fonts.enableDefaultFonts` options have been renamed to
736 `fonts.packages` and `fonts.enableDefaultPackages` respectively.
737
738- `services.hedgedoc` has been heavily refactored, reducing the amount of
739 declared options in the module. Most of the options should still work without
740 any changes to the configuration. Some options have been deprecated, as they
741 no longer have any effect. Refer to [PR
742 #244941](https://github.com/NixOS/nixpkgs/pull/244941) for more details.
743
744- `jq` was updated to v1.7. This is its [first release in 5
745 years](https://github.com/jqlang/jq/releases/tag/jq-1.7).
746
747- [`lib.attrsets.foldlAttrs`](https://nixos.org/manual/nixpkgs/stable#function-library-lib.attrsets.foldlAttrs)
748 now always evaluates the initial accumulator argument first.
749
750- [`lib.lists.foldl'`](https://nixos.org/manual/nixpkgs/stable#function-library-lib.lists.foldl-prime)
751 now always evaluates the initial accumulator argument first. If you depend on
752 the lazier behavior, consider using
753 [`lib.lists.foldl`](https://nixos.org/manual/nixpkgs/stable#function-library-lib.lists.foldl)
754 or
755 [`builtins.foldl'`](https://nixos.org/manual/nix/stable/language/builtins.html#builtins-foldl')
756 instead.
757
758- Now `magma` defaults to `magma-hip` instead of `magma-cuda`. It also
759 respects the `config.cudaSupport` and `config.rocmSupport` options.
760
761- The MariaDB C client library was upgraded from v3.2.x to v3.3.x. Refer to the
762 [upstream release
763 notes](https://mariadb.com/kb/en/mariadb-connector-c-33-release-notes/) for
764 more details.
765
766- Mattermost has been upgraded to extended support version 8.1 as the previously
767 packaged extended support version 7.8 is [reaching end-of-life](https://docs.mattermost.com/upgrade/extended-support-release.html).
768 Migration may take some time, refer to the [changelog](https://docs.mattermost.com/install/self-managed-changelog.html#release-v8-1-extended-support-release)
769 and [important upgrade notes](https://docs.mattermost.com/upgrade/important-upgrade-notes.html).
770
771- The `netdata` package disables cloud support by default now. To enable it use the `netdataCloud` package.
772
773- `networking.nftables` is no longer flushing all rulesets on every reload.
774 Use `networking.nftables.flushRuleset = true;` to enable the previous behaviour.
775
776- Node.js v14, v16 has been removed as they were end of life. Any dependent packages that contributors were not able to reasonably upgrade were dropped after a month of notice to their maintainers, were **removed**.
777 - This includes VSCode Server.
778 - This includes Kibana 7 as the ELK stack is unmaintained in nixpkgs and is marked for slow removal.
779
780- The application firewall `opensnitch` uses the process monitor method eBPF as
781 default now. This is recommended by upstream. The method may be changed with
782 the setting
783 [services.opensnitch.settings.ProcMonitorMethod](#opt-services.opensnitch.settings.ProcMonitorMethod).
784
785- `paperwork` is updated to v2.2. Documents scanned with this version will not
786 be visible to previous versions if you downgrade. Refer to the [upstream
787 announcement](https://forum.openpaper.work/t/paperwork-2-2-testing-phase/316#important-switch-from-jpeg-to-png-for-new-pages-2)
788 for details and workarounds.
789
790- The latest available version of Nextcloud is v27 (available as
791 `pkgs.nextcloud27`). The installation logic is as follows:
792 - If [`services.nextcloud.package`](#opt-services.nextcloud.package) is
793 specified explicitly, this package will be installed (**recommended**)
794 - If [`system.stateVersion`](#opt-system.stateVersion) is >=23.11,
795 `pkgs.nextcloud27` will be installed by default.
796 - If [`system.stateVersion`](#opt-system.stateVersion) is >=23.05,
797 `pkgs.nextcloud26` will be installed by default.
798 - Please note that an upgrade from v25 (or older) to v27 is not possible
799 directly. Please upgrade to `nextcloud26` (or earlier) first. Nextcloud
800 prohibits skipping major versions while upgrading. You may upgrade by
801 declaring [`services.nextcloud.package =
802 pkgs.nextcloud26;`](options.html#opt-services.nextcloud.package) inbetween.
803
804- `postgresql_11` has been removed since it'll stop receiving fixes on November
805 9th 2023.
806
807- `programs.gnupg.agent.pinentryFlavor` is set in `/etc/gnupg/gpg-agent.conf`
808 now. It will no longer take precedence over a `pinentry-program` set in
809 `~/.gnupg/gpg-agent.conf`.
810
811- `python3.pkgs.flitBuildHook` has been removed. Use `flit-core` and `format =
812 "pyproject"` instead.
813
814- Certificate generation via the `security.acme` limits the concurrent number
815 of running certificate renewals and generation jobs now. This is to avoid
816 spiking resource usage when processing many certificates at once. The limit
817 defaults to *5* and can be adjusted via `maxConcurrentRenewals`. Setting the
818 value to *0* disables the limits altogether.
819
820- `services.borgmatic.settings.location` and
821 `services.borgmatic.configurations.<name>.location` are deprecated, please
822 move your options out of sections to the global scope.
823
824- `services.fail2ban.jails` can be configured with attribute sets now, defining
825 settings and filters instead of lines. The stringed options `daemonConfig`
826 and `extraSettings` have respectively been replaced by `daemonSettings` and
827 `jails.DEFAULT.settings`. Those use attribute sets.
828
829- The `services.mbpfan` module has the option `aggressive` enabled by default
830 now. This is for better heat moderation. To get the upstream defaults you may
831 disable this.
832
833- Apptainer/Singularity defaults to using `"$out/var/lib"` for the
834 `LOCALSTATEDIR` configuration option instead of the top-level `"/var/lib"`
835 now. This change impacts the `SESSIONDIR` (container-run-time mount point)
836 configuration, which is set to `$LOCALSTATEDIR/<apptainer or
837 singularity>/mnt/session`. This detaches the packages from the top-level
838 directory, rendering the NixOS module optional.
839
840 The default behavior of the NixOS module `programs.singularity` stays
841 unchanged. We add a new option
842 `programs.singularity.enableExternalSysConfDir` (default to `true`) to
843 specify whether to set the top-level `"/var/lib"` as `LOCALSTATEDIR` or not.
844
845- The `services.sslh` module has been updated to follow [RFC
846 0042](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md).
847 As such, several options have been moved to the freeform attribute set
848 [services.sslh.settings](#opt-services.sslh.settings), which allows to change
849 any of the settings in {manpage}`sslh(8)`.
850
851 In addition, the newly added option
852 [services.sslh.method](#opt-services.sslh.method) allows to switch between
853 the {manpage}`fork(2)`, {manpage}`select(2)` and `libev`-based connection
854 handling method. Refer to the [sslh
855 docs](https://github.com/yrutschle/sslh/blob/master/doc/INSTALL.md#binaries)
856 for a comparison.
857
858- Suricata was upgraded from v6.0 to v7.0 and no longer considers HTTP/2
859 support as experimental. Refer to [upstream release
860 notes](https://forum.suricata.io/t/suricata-7-0-0-released/3715) for more
861 details.
862
863- `teleport` has been upgraded from major version 12 to major version 14.
864 Refer to upstream [upgrade
865 instructions](https://goteleport.com/docs/management/operations/upgrading/)
866 and release notes for
867 [v13](https://goteleport.com/docs/changelog/#1300-050823) and
868 [v14](https://goteleport.com/docs/changelog/#1400-092023). Note that Teleport
869 does not officially support upgrades across more than one major version at a
870 time. If you're running Teleport server components, it is recommended to
871 first upgrade to an intermediate v13.x version by setting
872 `services.teleport.package = pkgs.teleport_13`. Afterwards, this option can
873 be removed to upgrade to the default version (14).
874
875- `zfs` was updated from v2.1.x to v2.2.0, [enabling newer kernel support and
876 adding new features](https://github.com/openzfs/zfs/releases/tag/zfs-2.2.0).
877
878- The use of `sourceRoot = "source";`, `sourceRoot = "source/subdir";`, and
879 similar lines in package derivations using the default `unpackPhase` is
880 deprecated as it requires `unpackPhase` to always produce a directory named
881 "source". Use `sourceRoot = src.name`, `sourceRoot = "${src.name}/subdir";`,
882 or `setSourceRoot = "sourceRoot=$(echo */subdir)";` or similar instead.
883
884- The `django` alias in the python package set was upgraded to Django v4.x.
885 Applications that consume Django should always pin their python environment
886 to a compatible major version, so they can move at their own pace.
887
888 ```nix
889 {
890 python = python3.override {
891 packageOverrides = self: super: { django = super.django_3; };
892 };
893 }
894 ```
895
896- The `qemu-vm.nix` module by default now identifies block devices via
897 persistent names available in `/dev/disk/by-*`. Because the rootDevice is
898 identified by its filesystem label, it needs to be formatted before the VM is
899 started. The functionality of automatically formatting the rootDevice in the
900 initrd is removed from the QEMU module. However, for tests that depend on
901 this functionality, a test utility for the scripted initrd is added
902 (`nixos/tests/common/auto-format-root-device.nix`). To use this in a NixOS
903 test, import the module, e.g. `imports = [
904 ./common/auto-format-root-device.nix ];` When you use the systemd initrd, you
905 can automatically format the root device by setting
906 `virtualisation.fileSystems."/".autoFormat = true;`.
907
908- The `electron` packages places its application files in
909 `$out/libexec/electron` instead of `$out/lib/electron` now. Packages using
910 electron-builder will fail to build and need to be adjusted by changing `lib`
911 to `libexec`.

1115### Other Notable Changes {#sec-release-23.11-nixos-notable-changes}
1116
1117- The new option `system.switch.enable` was added. It is enabled by default.
1118 Disabling it makes the system unable to be reconfigured via `nixos-rebuild`.
1119 This is of advantage for image based appliances where updates are handled
1120 outside the image.
1121
1122- `services.searx` receives new options for better SearXNG support. This
1123 includes options for the built-in rate limiter, bot protection and
1124 automatically configuring a local Redis server.
1125
1126- The iptables firewall module installs the `nixos-firewall-tool` now which
1127 allows the user to easily temporarily open ports through the firewall.
1128
1129- A new option was added to the virtualisation module that enables specifying
1130 explicitly named network interfaces in QEMU VMs. The existing
1131 `virtualisation.vlans` is still supported for cases where the name of the
1132 network interface is irrelevant.
1133
1134- `services.outline` can be configured to use local filesystem storage now.
1135 Previously ony S3 storage was possible. This may be set using
1136 [services.outline.storage.storageType](#opt-services.outline.storage.storageType).
1137
1138- `pkgs.openvpn3` optionally supports systemd-resolved now. `programs.openvpn3`
1139 will automatically enable systemd-resolved support if
1140 [services.resolved.enable](#opt-services.resolved.enable) is set to true.
1141
1142- The
1143 [services.woodpecker-server.environmentFile](#opt-services.woodpecker-server.environmentFile)
1144 type was changed to list of paths to be more consistent to the
1145 woodpecker-agent module
1146
1147- `services.matrix-synapse` has new options to configure worker processes for
1148 matrix-synapse using
1149 [`services.matrix-synapse.workers`](#opt-services.matrix-synapse.workers).
1150 Configuring a local redis server using
1151 [`services.matrix-synapse.configureRedisLocally`](#opt-services.matrix-synapse.configureRedisLocally)
1152 is also possible now.
1153
1154- The `services.nginx` module gained a `defaultListen` option at server-level
1155 with support for PROXY protocol listeners. Also `proxyProtocol` is exposed in
1156 the `services.nginx.virtualHosts.<name>.listen` option now. This it is
1157 possible to run PROXY listeners and non-PROXY listeners at a server-level.
1158 Refer to [PR #213510](https://github.com/NixOS/nixpkgs/pull/213510/) for more
1159 details.
1160
1161- `services.restic.backups` adds wrapper scripts to your system path now. This
1162 wrapper script sets the same environment variables as the service, so restic
1163 operations can easily be run from the command line. This behavior can be
1164 disabled by setting `createWrapper` to `false`, for each backup
1165 configuration.
1166
1167- `services.prometheus.exporters` has a new exporter to monitor electrical
1168 power consumption based on PowercapRAPL sensor called
1169 [Scaphandre](https://github.com/hubblo-org/scaphandre). Refer to [PR
1170 #239803](https://github.com/NixOS/nixpkgs/pull/239803) for more details.
1171
1172- The `services.calibre-server` module has new options to configure the `host`,
1173 `port`, `auth.enable`, `auth.mode` and `auth.userDb` path. Refer to [PR
1174 #216497](https://github.com/NixOS/nixpkgs/pull/216497/) for more details.
1175
1176- `services.prometheus.exporters` has a new
1177 [exporter](https://github.com/hipages/php-fpm_exporter) to monitor PHP-FPM
1178 processes. Refer to [PR
1179 #240394](https://github.com/NixOS/nixpkgs/pull/240394) for more details.
1180
1181- `services.github-runner` and `services.github-runners.<name>` gained the
1182 option `nodeRuntimes`. This option defaults to `[ "node20" ]`. I.e., the
1183 service supports Node.js 20 GitHub Actions only. The list of Node.js versions
1184 accepted by `nodeRuntimes` tracks the versions the upstream GitHub Actions
1185 runner supports. Refer to [PR
1186 #249103](https://github.com/NixOS/nixpkgs/pull/249103) for details.
1187
1188- `programs.gnupg` has the option `agent.settings` now. This allows setting
1189 verbatim config values in `/etc/gnupg/gpg-agent.conf`.
1190
1191- `dockerTools.buildImage`, `dockerTools.buildLayeredImage` and
1192 `dockerTools.streamLayeredImage` use `lib.makeOverridable` now . This allows
1193 `dockerTools`-based images to be customized more efficiently at the Nix
1194 level.
1195
1196- `services.influxdb2` supports doing an automatic initial setup and
1197 provisioning of users, organizations, buckets and authentication tokens now.
1198 Refer to [PR #249502](https://github.com/NixOS/nixpkgs/pull/249502) for more
1199 details.
1200
1201- `wrapHelm` exposes `passthru.pluginsDir` now which can be passed to
1202 `helmfile`. For convenience, a top-level package `helmfile-wrapped` has been
1203 added, which inherits `passthru.pluginsDir` from `kubernetes-helm-wrapped`.
1204 Refer to [PR #217768](https://github.com/NixOS/nixpkgs/issues/217768) for
1205 more details.
1206
1207- The `boot.initrd.network.udhcp.enable` option allows control over DHCP during
1208 Stage 1 regardless of what `networking.useDHCP` is set to.
1209
1210- `networking.nftables` has the option `networking.nftables.table.<table>` now. This creates tables
1211 and have them be updated atomically, instead of flushing the ruleset.
1212
1213- `hardware.nvidia` gained `datacenter` options for enabling NVIDIA Data Center
1214 drivers and configuration of NVLink/NVSwitch topologies through
1215 `nv-fabricmanager`.
1216
1217- The new `boot.bcache.enable` option allows completely removing `bcache`
1218 mount support. It is enabled by default.
1219
1220- `security.sudo` provides two extra options now, while not changing the
1221 module's default behaviour:
1222 - `defaultOptions` controls the options used for the default rules;
1223 - `keepTerminfo` controls whether `TERMINFO` and `TERMINFO_DIRS` are preserved
1224 for `root` and the `wheel` group.
1225
1226- `virtualisation.googleComputeImage` provides a `efi` option to support UEFI
1227 booting now.
1228
1229- CoreDNS may be built with external plugins now. This may be done by
1230 overriding `externalPlugins` and `vendorHash` arguments like this:
1231
1232 ```nix
1233 {
1234 services.coredns = {
1235 enable = true;
1236 package = pkgs.coredns.override {
1237 externalPlugins = [
1238 {
1239 name = "fanout";
1240 repo = "github.com/networkservicemesh/fanout";
1241 version = "v1.9.1";
1242 }
1243 ];
1244 vendorHash = "<SRI hash>";
1245 };
1246 };
1247 }
1248 ```
1249
1250 To get the necessary SRI hash, set `vendorHash = "";`. The build will fail
1251 and produce the correct `vendorHash` in the error message.
1252
1253 If you use this feature, updates to CoreDNS may require updating `vendorHash`
1254 by following these steps again.
1255
1256- Using `fusuma` enables the following plugins now:

1262
1263- The Home Assistant module offers support for installing custom components and
1264 lovelace modules now. Available at
1265 [`services.home-assistant.customComponents`](#opt-services.home-assistant.customComponents)
1266 and
1267 [`services.home-assistant.customLovelaceModules`](#opt-services.home-assistant.customLovelaceModules).
1268
1269- TeX Live environments can now be built with the new `texlive.withPackages`.
1270 The procedure for creating custom TeX packages has been changed. Refer to the
1271 [Nixpkgs
1272 manual](https://nixos.org/manual/nixpkgs/stable/#sec-language-texlive-custom-packages)
1273 for more details.
1274
1275- In `wxGTK32`, the webkit module `wxWebView` has been enabled on all builds.
1276 Prior releases only enabled this on Darwin.
1277
1278- Support for WiFi6 (IEEE 802.11ax) and WPA3-SAE-PK was enabled in the
1279 `hostapd` package, along with a significant rework of the hostapd module.
1280
1281- LXD supports virtual machine instances now to complement the existing
1282 container support.
1283
1284- The `nixos-rebuild` command has been given a `list-generations` subcommand.
1285 Refer to `man nixos-rebuild` for more details.
1286
1287- [`sudo-rs`], a reimplementation of `sudo` in Rust, is now supported.
1288 An experimental new module `security.sudo-rs` was added.
1289 Switching to it (via ` security.sudo-rs.enable = true;`) introduces
1290 slight changes in sudo behaviour, due to `sudo-rs`' current limitations:
1291 - terminfo-related environment variables aren't preserved for `root` and `wheel`;
1292 - `root` and `wheel` are not given the ability to set (or preserve)
1293 arbitrary environment variables.
1294
1295 **Note:** The `sudo-rs` module only takes configuration through `security.sudo-rs`,
1296 and in particular does not automatically use previously-set rules; this could be
1297 achieved with `security.sudo-rs.extraRules = security.sudo.extraRules;` for instance.
1298
1299[`sudo-rs`]: https://github.com/memorysafety/sudo-rs/
1300
1301- There is a new NixOS option when writing NixOS tests
1302 `testing.initrdBackdoor`, that enables `backdoor.service` in initrd. Requires
1303 `boot.initrd.systemd.enable` to be enabled. Boot will pause in Stage 1 at
1304 `initrd.target`, and will listen for commands from the `Machine` python
1305 interface, just like Stage 2 normally does. This enables commands to be sent
1306 to test and debug Stage 1. Use `machine.switch_root()` to leave Stage 1 and
1307 proceed to Stage 2.
1308
1309- The Linux kernel module `msr` (refer to
1310 [`msr(4)`](https://man7.org/linux/man-pages/man4/msr.4.html)), which provides
1311 an interface to read and write the model-specific registers (MSRs) of an x86
1312 CPU, can now be configured via `hardware.cpu.x86.msr`.
1313
1314- The `qemu-vm.nix` module now supports disabling overriding `fileSystems` with
1315 `virtualisation.fileSystems`. This enables the user to boot VMs from
1316 "external" disk images not created by the qemu-vm module. You can stop the
1317 qemu-vm module from overriding `fileSystems` by setting
1318 `virtualisation.fileSystems = lib.mkForce { };`.
1319
1320- When using [split parity files](https://www.snapraid.it/manual#7.1) in `snapraid`,
1321 the snapraid-sync systemd service will no longer fail to run.
1322
1323- `wpa_supplicant`'s configuration file cannot be read by non-root users, and
1324 secrets (such as Pre-Shared Keys) can safely be passed via
1325 `networking.wireless.environmentFile`.
1326
1327 The configuration file could previously be read, when `userControlled.enable` (non-default),
1328 by users who are in both `wheel` and `userControlled.group` (defaults to `wheel`)

1331## Nixpkgs Library {#sec-release-23.11-nixpkgs-lib}
1332
1333### Breaking Changes {#sec-release-23.11-lib-breaking}
1334
1335- [`lib.lists.foldl'`](https://nixos.org/manual/nixpkgs/stable#function-library-lib.lists.foldl-prime)
1336 now always evaluates the initial accumulator argument first. If you depend on
1337 the lazier behavior, consider using
1338 [`lib.lists.foldl`](https://nixos.org/manual/nixpkgs/stable#function-library-lib.lists.foldl)
1339 or
1340 [`builtins.foldl'`](https://nixos.org/manual/nix/stable/language/builtins.html#builtins-foldl')
1341 instead.
1342- [`lib.attrsets.foldlAttrs`](https://nixos.org/manual/nixpkgs/stable#function-library-lib.attrsets.foldlAttrs)
1343 now always evaluates the initial accumulator argument first.
1344- Now that the internal NixOS transition to Markdown documentation is complete,
1345 `lib.options.literalDocBook` has been removed after deprecation in 22.11.
1346- `lib.types.string` is now fully deprecated and gives a warning when used.
1347
1348### Additions and Improvements {#sec-release-23.11-lib-additions-improvements}
1349
1350- [`lib.fileset`](https://nixos.org/manual/nixpkgs/stable#sec-functions-library-fileset):
1351 A new sub-library to select local files to use for sources, designed to be
1352 easy and safe to use.
1353
1354 This aims to be a replacement for `lib.sources`-based filtering. To learn
1355 more about it, see [the blog
1356 post](https://www.tweag.io/blog/2023-11-28-file-sets/) or [the
1357 tutorial](https://nix.dev/tutorials/file-sets).
1358
1359- [`lib.gvariant`](https://nixos.org/manual/nixpkgs/stable#sec-functions-library-gvariant):
1360 A partial and basic implementation of GVariant formatted strings. See
1361 [GVariant Format
1362 Strings](https://docs.gtk.org/glib/gvariant-format-strings.html) for details.
1363
1364 :::{.warning}
1365 This API is not considered fully stable and it might therefore
1366 change in backwards incompatible ways without prior notice.

1419
1420 [`mkPackageOption`](https://nixos.org/manual/nixpkgs/stable#function-library-lib.options.mkPackageOption).
1421 now also supports the `pkgsText` attribute.
1422
1423Module system:
1424- Options in the `options` module argument now have the `declarationPositions`
1425 attribute containing the position where the option was declared:
1426 ```
1427 $ nix-repl -f '<nixpkgs/nixos>' [...]
1428 nix-repl> :p options.environment.systemPackages.declarationPositions
1429 [ {
1430 column = 7;
1431 file = "/nix/store/vm9zf9wvfd628cchj0hdij1g4hzjrcz9-source/nixos/modules/config/system-path.nix";
1432 line = 62;
1433 } ]
1434 ```
1435
1436 Not to be confused with `definitionsWithLocations`, which is the same but for option _definitions_.
1437- Improved error message for option declarations missing `mkOption`
1438
1439### Deprecations {#sec-release-23.11-lib-deprecations}
1440
1441- `lib.meta.getExe pkg` (also available as `lib.getExe`) now gives a warning if
1442 `pkg.meta.mainProgram` is not set, but it continues to default to the
1443 derivation name. Nixpkgs accepts PRs that set `meta.mainProgram` on packages
1444 where it makes sense. Use `lib.getExe' pkg "some-command"` to avoid the
1445 warning and/or select a different executable.
