Release 23.11 (“Tapir”, 2023.11/29)
The NixOS release team is happy to announce a new version of NixOS. The release is called NixOS 23.11 ("Tapir").
NixOS is a Linux distribution, whose set of packages can also be used on other Linux systems and macOS.
Support is planned until the end of June 2024, handing over to NixOS 24.05.
To upgrade to the latest release, follow the upgrade chapter and check the Breaking Changes section for packages and services used in your configuration.
The team is excited about the many software updates and improvements in this release. Just to name a few, do check the updates
for GNOME packages, systemd, glibc, the ROCM package set, and hostapd (which brings support for WiFi6 (IEEE 802.11ax) and WPA3-SAE-PK).
Make sure to also check the many updates in the Nixpkgs library when developing your own packages.

Breaking Changes
-
services.postgresql.ensurePermissionshas been deprecated in favor ofservices.postgresql.ensureUsers.*.ensureDBOwnershipwhich simplifies the setup of database owned by a certain system user in local database contexts (which make use of peer authentication via UNIX sockets), migration guidelines were provided in the NixOS manual, please refer to them if you are affected by a PostgreSQL 15 changing the wayGRANT ALL PRIVILEGESis working.services.postgresql.ensurePermissionswill be removed in 24.05. All NixOS modules were migrated using one of the strategy, e.g.ensureDBOwnershiporpostStart. Refer to the PR #266270 for more details. -
network-online.targethas been fixed to no longer time out for systems withnetworking.useDHCP = trueandnetworking.useNetworkd = true. Workarounds for this can be removed. -
The
boot.loader.raspberryPioptions have been marked deprecated, with intent of removal for NixOS 24.11. They had a limited use-case, and do not work like people expect. They required either very old installs from (before mid-2019) or customized builds out of scope of the standard and generic AArch64 support. That option set never supported the Raspberry Pi 4 family of devices. -
python3.pkgs.sequoiawas removed in favor ofpython3.pkgs.pysequoia. The latter package is based on upstream's dedicated repository for sequoia's Python bindings, where the Python bindings from gitlab:sequoia-pgp/sequoia were removed long ago. -
writeTextFilerequiresexecutableto be boolean now, values likenullor""will fail to evaluate now. -
The latest version of
cloneheronow stores custom content in~/.clonehero. Refer to the migration instructions for more details. Typically, these content files would exist along side the binary, but the previous build used a wrapper script that would store them in~/.config/unity3d/srylain Inc_/Clone Hero. -
services.mastodondoesn't support providing a TCP port to itsstreamingcomponent anymore, as upstream implemented parallelization by running multiple instances instead of running multiple processes in one instance. Please create a PR if you are interested in this feature.
Due to this, the desired number of such instances {option}services.mastodon.streamingProcessesnow needs to be declared explicitly. -
The
services.hostapdmodule was rewritten to supportpasswordFilelike options, WPA3-SAE, and management of multiple interfaces. This breaks compatibility with older configurations.hostapdis now started with additional systemd sandbox/hardening options for better security.services.hostapd.interfacewas replaced with a per-radio and per-bss configuration scheme using services.hostapd.radios.services.hostapd.wpahas been replaced by services.hostapd.radios.<name>.networks.<name>.authentication.wpaPassword and services.hostapd.radios.<name>.networks.<name>.authentication.saePasswords which configure WPA2-PSK and WP3-SAE respectively.- The default authentication has been changed to WPA3-SAE. Options for other (legacy) schemes are still available.
-
python3.pkgs.fetchPypiandpython3Packages.fetchPypihave been deprecated in favor of top-levelfetchPypi. -
xdg-desktop-portal has been updated to 1.18, which reworked how portal implementations are selected. If you roll your own desktop environment, you should either set
xdg.portal.configorxdg.portal.configPackages, which allow fine-grained control over which portal backend to use for specific interfaces, as described in {manpage}portals.conf(5).If you don't provide configurations, a portal backend will only be considered when the desktop you use matches its deprecated
UseInkey. While some NixOS desktop modules should already ship one for you, it is suggested to test portal availability by trying Door Knocker and ASHPD Demo. If things regressed, you may runG_MESSAGES_DEBUG=all /path/to/xdg-desktop-portal/libexec/xdg-desktop-portalfor ideas on which config file and which portals are chosen. -
passnow does not containpassword-store.el. Users should getpassword-store.elfrom Emacs lisp package setemacs.pkgs.password-store. -
services.knotnow supports.settingsfrom RFC42. The previous.extraConfigstill works the same, but it displays a warning now. -
services.invoiceplanenow supports.settingsfrom RFC42. The previous.extraConfigstill works the same way, but it displays a warning now. -
mudoes not installmu4efiles by default now. Users should getmu4efrom Emacs lisp package setemacs.pkgs.mu4e. -
mariadbnow defaults tomariadb_1011instead ofmariadb_106, meaning the default version was upgraded from v10.6.x to v10.11.x. Refer to the upgrade notes for potential issues. -
getenthas been moved fromglibc'sbinoutput to its own dedicated output, reducing closure size for many dependents. Dependents using thegetentalias should not be affected; others should move from usingglibc.binorgetBin glibctogetent(which also improves compatibility with non-glibc platforms). -
maintainers/scripts/update-luarocks-packagesis now a proper packageluarocks-packages-updaterthat can be run to maintain out-of-tree luarocks packages. -
The
users.users.<name>.passwordFilehas been renamed tousers.users.<name>.hashedPasswordFileto avoid possible confusions. The option is in fact the file-based version ofhashedPassword, notpassword, and expects a file containing the {manpage}crypt(3)hash of the user password. -
chromiumBetaandchromiumDevhave been removed due to the lack of maintenance in nixpkgs. Consider usingchromiuminstead. -
google-chrome-betaandgoogle-chrome-devhave been removed due to the lack of maintenance in nixpkgs. Consider usinggoogle-chromeinstead. -
The
services.ananicy.extraRulesoption now has the type oflistOf attrsinstead ofstring. -
buildVimPluginFrom2Nixhas been renamed tobuildVimPlugin, which now now skipsconfigurePhaseandbuildPhase. -
JACK tools (
jack_*exceptjack_control) have moved from thejack2package tojack-example-tools. -
The
waagentservice does provisioning now. -
The
matrix-synapsepackage & module have undergone some significant internal changes, for most setups no intervention is needed, though:- The option
services.matrix-synapse.packageis read-only now. For modifying the package, use an overlay which modifiesmatrix-synapse-unwrappedinstead. More on that below. - The
enableSystemd&enableRedisarguments have been removed andmatrix-synapsehas been renamed tomatrix-synapse-unwrapped. Also, several optional dependencies (such aspsycopg2orauthlib) have been removed. - These optional dependencies are automatically added via a wrapper
(
pkgs.matrix-synapse.override { extras = ["redis"]; }forhiredis&txredisapifor instance) if the relevant config section is declared inservices.matrix-synapse.settings. For instance, ifservices.matrix-synapse.settings.redis.enabledis set totrue,"redis"will be automatically added to theextraslist ofpkgs.matrix-synapse. - A list of all extras (and the extras enabled by default) can be found at
the option's reference for
services.matrix-synapse.extras. - In some cases (e.g. for running synapse workers) it was necessary to re-use
the
PYTHONPATHofmatrix-synapse.service's environment to have all plugins available. This isn't necessary anymore, insteadconfig.services.matrix-synapse.packagecan be used as it points to the wrapper with properly configuredextrasand also all plugins defined viaservices.matrix-synapse.pluginsavailable. This is also the reason for why the option is read-only now, it's supposed to be set by the module only.
- The option
-
netboxwas updated to v3.6.services.netbox.packagestill defaults to v3.5 ifstateVersionis earlier than 23.11. Refer to upstream's breaking changes for v3.6.0 and upgrade NetBox by changingservices.netbox.package. Database migrations will be run automatically. -
etcdhas been updated to v3.5. Refer to upgrade guides for v3.3 to v3.4 and v3.4 to v3.5 for more details. -
gitlabinstallations created or updated between versions [15.11.0, 15.11.2] have an incorrect database schema. This will become a problem when upgrading togitlab>=16.2.0. A workaround for affected users can be found in the GitLab docs. -
consulhas been updated to v1.16.0. Refer to the release note for more details. Once a new Consul version has started and upgraded it's data directory, it generally cannot be downgraded to the previous version. -
llvmPackages_rocmhas been moved torocmPackages.llvm. -
hip,rocm-opencl-runtime,rocm-opencl-icd, androcclrhave been combined intorocmPackages.clr. -
clang-ocl,clr,composable_kernel,hipblas,hipcc,hip-common,hipcub,hipfft,hipfort,hipify,hipsolver,hipsparse,migraphx,miopen,miopengemm,rccl,rdc,rocalution,rocblas,rocdgbapi,rocfft,rocgdb,rocm-cmake,rocm-comgr,rocm-core,rocm-device-libs,rocminfo,rocmlir,rocm-runtime,rocm-smi,rocm-thunk,rocprim,rocprofiler,rocrand,rocr-debug-agent,rocsolver,rocsparse,rocthrust,roctracer,rocwmma, andtensilehave been moved torocmPackages. -
himalayahas been updated to v0.8.0, which drops the native TLS support (in favor of Rustls) and add OAuth 2.0 support. Refer to the release note for more details. -
nix-prefetch-gitnow ignores global and user git config, to improve reproducibility. -
The services.caddy.acmeCA option defaults to
nullinstead of"https://acme-v02.api.letsencrypt.org/directory"now. To use all of Caddy's default ACME CAs and enable Caddy's automatic issuer fallback feature by default, as recommended by upstream. -
The default priorities of
services.nextcloud.phpOptionshave changed. This means that e.g.services.nextcloud.phpOptions."opcache.interned_strings_buffer" = "23";doesn't discard all of the other defaults from this option anymore. The attribute values ofphpOptionsare still defaults, these can be overridden as shown here.To override all of the options (including
upload_max_filesize,post_max_sizeandmemory_limitwhich all point toservices.nextcloud.maxUploadSizeby default) can be done like this:{ services.nextcloud.phpOptions = lib.mkForce { # ... }; } -
php80is no longer supported due to upstream not supporting this version anymore. -
PHP defaults to PHP 8.2 now, updated from v8.1.
-
GraalVM has been updated to the latest version, and this brings significant changes. Upstream don't release multiple versions targeting different JVMs anymore, so now we only have one GraalVM derivation (
graalvm-ce). While at first glance the version may seem a downgrade (v22.3.1 -> v21.0.0), the major version is now following the JVM it targets (so this latest version targets JVM 21). Also some products likellvm-installable-svmandnative-image-svmwere incorporate to the main GraalVM derivation, so they're included by default. -
GraalPy (
graalCEPackages.graalpy), TruffleRuby (graalCEPackages.truffleruby), GraalJS (graalCEPackages.graaljs) and GraalNodeJS (grallCEPackages.graalnodejs) are now independent from the main GraalVM derivation. -
The ISC DHCP package and corresponding module have been removed, because they are EOL upstream. Refer to this post for details and switch to a different DHCP implementation like kea or dnsmasq.
-
prometheus-unbound-exporterhas been replaced by the Let's Encrypt maintained version, since the previous version was archived. This requires some changes to the module configuration, most notablecontrolInterfaceneeds migration towardsunbound.hostand requires either thetcp://orunix://URI scheme. -
odoodefaults to v16 now, updated from v15. -
varnishwas upgraded from v7.2.x to v7.4.x. Refer to upgrade guides vor v7.3 and v7.4. The current LTS version is still offered asvarnish60. -
util-linuxis now supported on Darwin and is no longer an alias tounixtools. Use theunixtools.util-linuxpackage for access to the Apple variants of the utilities. -
services.keydchanged API. Now you can create multiple configuration files. -
baloo, the file indexer and search engine used by KDE now has a patch to prevent files from constantly being reindexed when the device IDs of the their underlying storage change. This happens frequently when using btrfs or LVM. The patch has not yet been accepted upstream but it provides a significantly improved experience. When upgrading, reset baloo to get a clean index:balooctl disable ; balooctl purge ; balooctl enable. -
The
vlockprogram from thekbdpackage has been moved into its own package output and should now be referenced explicitly askbd.vlockor replaced with an alternative such as the standalonevlockpackage orphyslock. -
fileSystems.<name>.autoFormatnow usessystemd-makefs, which does not accept formatting options. Therefore,fileSystems.<name>.formatOptionshas been removed. -
fileSystems.<name>.autoResizeusessystemd-growfsto resize the file system online in Stage 2 now. This means thatf2fsandext2can no longer be auto resized, whilexfsandbtrfsnow can be. -
fuse3has been updated from v3.11.0 to v3.16.2. Refer to the changelog for an overview of the changes.Unsupported mount options are no longer silently accepted (since 3.15.0). The affected mount options are:
atime,diratime,lazytime,nolazytime,relatime,norelatime,strictatime.For example,
$ sshfs 127.0.0.1:/home/test/testdir /home/test/sshfs_mnt -o atimewould previously terminate successfully with the mount point established, now it outputs the error message
fuse: unknown option(s): `-o atime'and terminates with exit status 1. -
nixos-rebuild {switch,boot,test,dry-activate}runs the system activation insidesystemd-runnow, creating an ephemeral systemd service and protecting the system switch against issues like network disconnections during remote (e.g. SSH) sessions. This has the side effect of running the switch in an isolated environment, that could possible break post-switch scripts that depends on things like environment variables being set. If you want to opt-out from this behavior for now, you may set theNIXOS_SWITCH_USE_DIRTY_ENVenvironment variable before runningnixos-rebuild. However, keep in mind that this option will be removed in the future. -
The
services.vaultwarden.configoption default value was changed to make Vaultwarden only listen on localhost, following the secure defaults for most NixOS services. -
services.lemmy.settings.federationwas removed in v0.17.0 and no longer has any effect. To enable federation, the hostname must be set in the configuration file and then federation must be enabled in the admin web UI. Refer to the release notes for more details. -
pict-rswas upgraded from v0.3 to v0.4 and contains an incompatible database & configuration change. To upgrade on systems withstateVersion = "23.05";or older follow the migration steps from https://git.asonix.dog/asonix/pict-rs#user-content-0-3-to-0-4-migration-guide and setservices.pict-rs.package = pkgs.pict-rs;. -
The following packages in
haskellPackageshave a separate bin output now:cabal-fmt,calligraphy,eventlog2html,ghc-debug-brick,hindent,nixfmt,releaser. This means you need to replace e.g."${pkgs.haskellPackages.nixfmt}/bin/nixfmt"with"${lib.getBin pkgs.haskellPackages.nixfmt}/bin/nixfmt"or"${lib.getExe pkgs.haskellPackages.nixfmt}". The binaries also won’t be in scope if you rely on them being installed e.g. viaghcWithPackages.environment.packagespicks thebinoutput automatically, so for normal installation no intervention is required. Also, toplevel attributes likepkgs.nixfmtare not impacted negatively by this change. -
spamassassinno longer supports theHashcashmodule. The module needs to be removed from theloadpluginlist if it was copied over from the defaultinitPreConfoption. -
nanowas removed fromenvironment.defaultPackages. To not leave systems without a editor, nowprograms.nano.enableis enabled by default. -
programs.nano.nanorcandprograms.nano.syntaxHighlightno longer have an effect unlessprograms.nano.enableis set to true which is the default. -
services.outline.sequelizeArgumentshas been removed, asoutlineno longer executes database migrations via thesequelizecli. -
The binary of the package
cloud-sql-proxyhas changed fromcloud_sql_proxytocloud-sql-proxy. -
The module
services.apache-kafkawas largely rewritten and has certain breaking changes. To be precise, this means that the following things have changed:- Most settings have been migrated to services.apache-kafka.settings.
- By virtue of being less opinionated, it is now possible to use the module
to run Apache Kafka in KRaft mode instead of Zookeeper mode.
- A few options have been added to assist in this mode.
-
Garage has been upgraded to v0.9.x.
services.garage.packageneeds to be explicitly set now, so version upgrades can be done in a controlled fashion. For this, we exposegarage_x_yattributes which can be set here. -
vomsandxrootdnow moves the$out/etccontent to the$etcoutput instead of$out/etc.orig, when input argumentexternalEtcis notnull. -
The
woodpecker-*CI packages have been updated to v1.0.0. This release is wildly incompatible with the v0.15.x versions that were previously packaged. Refer to upstream's documentation to learn how to update your CI configurations. -
Meilisearch was updated from v1.3.1 to v1.5.0. The update has breaking changes about backslashes and filtering. Refer to the release announcement for more details.
-
The Caddy module gained a new option named
services.caddy.enableReloadwhich is enabled by default. It allows reloading the service instead of restarting it, if only a config file has changed. This option must be disabled if you have turned off the Caddy admin API. If you keep this option enabled, you should consider settinggrace_periodto a non-infinite value to prevent Caddy from delaying the reload indefinitely. -
mdraid support is optional now. This reduces initramfs size and prevents the potentially undesired automatic detection and activation of software RAID pools. It is disabled by default in new configurations (determined by
stateVersion), but the appropriate settings will be generated bynixos-generate-configwhen installing to a software RAID device, so the standard installation procedure should be unaffected. If you have custom configs relying on mdraid, ensure that you usestateVersioncorrectly or setboot.swraid.enablemanually. On systems with an updatedstateVersionwe now also emit warnings ifmdadm.confdoes not contain the minimum required configuration necessary to run the dynamically enabled monitoring daemons. -
The
go-ethereumpackage has been updated to v1.12.0. This drops support for proof-of-work. Its GraphQL API now encodes all numeric values as hex strings and the GraphQL UI is updated to v2.0. The default database has changed fromleveldbtopebblebutleveldbcan be forced with the --db.engine=leveldb flag. Thecheckpoint-admincommand was removed along with trusted checkpoints. -
The
aseprite-unfreepackage has been upgraded from v1.2.16.3 to v1.2.40. The free version of aseprite has been dropped because it is EOL and the package attribute now points to the unfree version. A maintained fork of the last free version of Aseprite, named 'LibreSprite', is available in thelibrespritepackage. -
The default
kopsversion is v1.28.0 now and support for v1.25 and older have been dropped. -
pharohas been updated to latest stable v10.0.8, which is compatible with the latest stable and oldstable images (Pharo 10 and 11). The VM in question is the 64bit Spur. The 32bit version has been dropped due to lack of maintenance. The Cog VM has been deleted because it is severely outdated. Finally, thepharo-launcherpackage has been deleted because it was not compatible with the newer VM, and due to lack of maintenance. -
Emacs mainline v29 was introduced. This new version includes many major additions, most notably
tree-sittersupport (enabled by default) and the pgtk variant (useful for Wayland users), which is available under the attributeemacs29-pgtk. -
Emacs macport version 29 was introduced.
-
The option
services.networking.networkmanager.enableFccUnlockwas removed in favor ofnetworking.networkmanager.fccUnlockScripts, which allows specifying unlock scripts explicitly. The previous option enabled all unlock scripts bundled with ModemManager, which is risky, and didn't allow using vendor-provided unlock scripts at all. -
The
html-prooferpackage has been updated from major version 3 to major version 5, which includes breaking changes. -
kratoshas been updated from v0.10.1 to the first stable v1.0.0, please read the v0.10.1 to v0.11.0, v0.11.0 to v0.11.1, v0.11.1 to v0.13.0 and v0.13.0 to v1.0.0 upgrade guides. The most notable breaking change is the introduction of one-time passwords (code) and update of the default recovery strategy fromlinktocode. -
The
hailmodule was removed, ashailwas unmaintained since 2017. -
Package
noto-fonts-emojiwas renamed tonoto-fonts-color-emoji. Refer to PR #221181 for more details. -
Package
cloud-sql-proxywas renamed togoogle-cloud-sql-proxyas it cannot be used with other cloud providers. -
Package
pashwas removed due to being archived upstream. Usepowershellas an alternative. -
The option
services.plausible.releaseCookiePathhas been removed. Plausible does not use any distributed Erlang features, and does not plan to (refer to discussion), Thus NixOS disables them now , and the Erlang cookie becomes unnecessary. You may delete the file thatreleaseCookiePathwas set to. -
security.sudo.extraRulesincludesroot's default rule now, with ordering priority 400. This is functionally identical for users not specifying rule order, or relying onmkBeforeandmkAfter, but may impact users callingmkOrder nwith n ≤ 400. -
X keyboard extension (XKB) options have been reorganized into a single attribute set,
services.xserver.xkb. Specifically,services.xserver.layoutisservices.xserver.xkb.layoutnow,services.xserver.extraLayoutsisservices.xserver.xkb.extraLayoutsnow,services.xserver.xkbModelisservices.xserver.xkb.modelnow,services.xserver.xkbOptionsisservices.xserver.xkb.optionsnow ,services.xserver.xkbVariantisservices.xserver.xkb.variantnow, andservices.xserver.xkbDirisservices.xserver.xkb.dirnow. -
networking.networkmanager.firewallBackendwas removed as NixOS is now using iptables-nftables-compat even when using iptables, therefore Networkmanager uses the nftables backend unconditionally now. -
romewas removed because it is no longer maintained and is succeeded bybiome. -
The
prometheus-knot-exporterwas migrated to a version maintained by CZ.NIC. Various metric names have changed, so checking existing rules is recommended. -
The
services.mtr-exporter.targethas been removed in favor ofservices.mtr-exporter.jobswhich allows specifying multiple targets. -
blender-with-packageshas been deprecated in favor ofblender.withPackages, for exampleblender.withPackages (ps: [ps.bpycv]). It behaves similarly topython3.withPackages. -
Setting
nixpkgs.configoptions while providing an externalpkgsinstance will now raise an error instead of silently ignoring the options. NixOS modules no longer setnixpkgs.configto accommodate this. This specifically affectsservices.locate,services.xserver.displayManager.lightdm.greeters.tinyandprograms.firefoxNixOS modules. No manual intervention should be required in most cases, however, configurations relying on those modules affecting packages outside the system environment should switch to explicit overlays. -
privacyidea(and the correspondingprivacyidea-ldap-proxy) has been removed from nixpkgs because it has severely outdated dependencies that became unmaintainable with nixpkgs' python package-set. -
daggerwas removed because using a package calleddaggerand packaging it from source violates their trademark policy. -
win-virtiopackage was renamed tovirtio-winto be consistent with the upstream package name. -
ps3netsrvhas been replaced with the webman-mod fork, the executable has been renamed fromps3netsrv++tops3netsrvand cli parameters have changed. -
ssm-agentpackage and module were renamed toamazon-ssm-agentto be consistent with the upstream package name. -
services.kea.{ctrl-agent,dhcp-ddns,dhcp,dhcp6}now use separate runtime directories instead of/run/keato work around the runtime directory being cleared on service start. -
mkDerivationrejects MD5 hashes now. -
The
junicodefont package has been updated to major v2, which is a font family now. In particular, plainJunicode.ttfno longer exists. In addition, TrueType font files are now placed infont/truetypeinstead offont/junicode-ttf; this change does not affect use viafonts.packagesoption. -
The
prayerpackage as well asservices.prayerhave been removed because it's been unmaintained for several years and the author's website has vanished. -
The
chronyNixOS module now tracks the real-time clock drift from the system clock withrtcfileand automatically adjusts it withrtcautotrimwhen it exceeds the maximum error specified inservices.chrony.autotrimThreshold(defaults to 30 seconds). If you enabledrtcsyncinextraConfig, you should remove RTC related options fromextraConfig. If you do not want chrony configured to keep the RTC in check, you can setservices.chrony.enableRTCTrimming = false;. -
trilium-desktopandtrilium-serverhave been updated to v0.61. For existing installations, upgrading to this version is supported only after running v0.60.x at least once. If you are still on an older version, make sure to update to v0.60 (available in NixOS 23.05) first and only then to v0.61 (available in NixOS 23.11). -
Cassandra now defaults to v4.x, updated from v3.11.x.
-
FoundationDB now defaults to major version 7.
-
glibc has been updated from v2.37 to v2.38. Refer to the the release notes for more details.
-
linuxPackages_testing_bcachefsis now soft-deprecated bylinuxPackages_testing.- Please consider changing your NixOS configuration's
boot.kernelPackagestolinuxPackages_testinguntil a stable kernel with bcachefs support is released.
- Please consider changing your NixOS configuration's
-
PostgreSQL now defaults to major version 15.
-
All ROCm packages have been updated to v5.7.0.
- ROCm package attribute sets are
versioned:
rocmPackages->rocmPackages_5.
- ROCm package attribute sets are
versioned:
-
systemd has been updated from v253 to v254, refer to the release notes for more details.
boot.resumeDevicemust be specified when hibernating if not in EFI mode.- systemd may warn your system about the permissions of your ESP partition
(often
/boot), this warning can be ignored for now, we are looking into a satisfying solution regarding this problem. - Updating with
nixos-rebuild bootand rebooting is recommended, since in some rare cases thenixos-rebuild switchinto the new generation on a live system might fail due to missing mount units.
-
If the user has a custom shell enabled via
users.users.${USERNAME}.shell = ${CUSTOMSHELL}, the assertion will require them to also setprograms.${CUSTOMSHELL}.enable = true. This is generally safe behavior, but for anyone needing to opt out from the checkusers.users.${USERNAME}.ignoreShellProgramCheck = truewill do the job. -
yarn-berryhas been updated to v4.0.1. This means that NodeJS versions less v18.12 are no longer supported by it. Refer to the upstream changelog for more details. -
GNOME has been updated to v45. Refer to the release notes for more details. Notably, Loupe has replaced Eye of GNOME as the default image viewer, Snapshot has replaced Cheese as the default camera application, and Photos will no longer be installed.
-
The module
services.ankisyncdhas been switched to anki-sync-server-rs. The former version written in Python was difficult to update, did not receive updates in a while, and did not support recent versions of Anki.Unfortunately all servers supporting new clients do not support the older sync protocol that was used in the old server. This includes newer version of anki-sync-server, Anki's built in sync server and this new Rust package. Thus old clients will also need updating. In particular nixpkgs's Anki package is also being updated in this release.
The module update takes care of the new config syntax. The data itself (i.e. user login and card information) is compatible. Thus users of the module will be able to simply log in again after updating both client and server without any extra action needed to be taken.
-
The argument
vendorSha256ofbuildGoModuleis deprecated. UsevendorHashinstead. Refer to PR #259999) for more details. -
go-modulesinbuildGoModuleattrs has been renamed togoModules. -
The package
cawbirdis dropped from nixpkgs. It broke by the Twitter API closing down and has been abandoned upstream. -
The Cinnamon module now enables XDG desktop integration by default. If you are experiencing collisions related to xdg-desktop-portal-gtk you can safely remove
xdg.portal.extraPortals = [ pkgs.xdg-desktop-portal-gtk ];from your NixOS configuration. -
GNOME, Pantheon, Cinnamon modules no longer force Qt applications to use Adwaita style. This implemantion was buggy and is no longer maintained upstream. Specifically, Cinnamon defaults to the gtk2 style instead now, following the default in Linux Mint). If you still want Adwaita used, you may add the following options to your configuration. Please be aware, that it will probably be removed eventually.
{ qt = { enable = true; platformTheme = "gnome"; style = "adwaita"; }; } -
DocBook option documentation is no longer supported, all module documentation now uses Markdown.
-
Docker defaults to v24 now, as 20.10 is stopping to receive security updates and bug fixes after December 10, 2023.
-
Elixir defaults to v1.15 now. Refer to their changelog for more details.
-
The
extendfunction ofllvmPackageshas been removed due it coming from thetoolsattrset thus only extending thetoolattrset. A possible replacement is to construct the set fromlibrariesandtools, or patch nixpkgs. -
ffmpegdefaults toffmpeg_6now, upgrading fromffmpeg_5. -
fontconfigdefaults to using greyscale antialiasing now. Previously subpixel antialiasing was used because of a recommendation from one of the downstreams. You can change this value by configuring accordingly. -
The
fonts.fontsandfonts.enableDefaultFontsoptions have been renamed tofonts.packagesandfonts.enableDefaultPackagesrespectively. -
services.hedgedochas been heavily refactored, reducing the amount of declared options in the module. Most of the options should still work without any changes to the configuration. Some options have been deprecated, as they no longer have any effect. Refer to PR #244941 for more details. -
jqwas updated to v1.7. This is its first release in 5 years. -
lib.attrsets.foldlAttrsnow always evaluates the initial accumulator argument first. -
lib.lists.foldl'now always evaluates the initial accumulator argument first. If you depend on the lazier behavior, consider usinglib.lists.foldlorbuiltins.foldl'instead. -
Now
magmadefaults tomagma-hipinstead ofmagma-cuda. It also respects theconfig.cudaSupportandconfig.rocmSupportoptions. -
The MariaDB C client library was upgraded from v3.2.x to v3.3.x. Refer to the upstream release notes for more details.
-
Mattermost has been upgraded to extended support version 8.1 as the previously packaged extended support version 7.8 is reaching end-of-life. Migration may take some time, refer to the changelog and important upgrade notes.
-
The
netdatapackage disables cloud support by default now. To enable it use thenetdataCloudpackage. -
networking.nftablesis no longer flushing all rulesets on every reload. Usenetworking.nftables.flushRuleset = true;to enable the previous behaviour. -
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.
- This includes VSCode Server.
- This includes Kibana 7 as the ELK stack is unmaintained in nixpkgs and is marked for slow removal.
-
The application firewall
opensnitchuses the process monitor method eBPF as default now. This is recommended by upstream. The method may be changed with the setting services.opensnitch.settings.ProcMonitorMethod. -
paperworkis updated to v2.2. Documents scanned with this version will not be visible to previous versions if you downgrade. Refer to the upstream announcement for details and workarounds. -
The latest available version of Nextcloud is v27 (available as
pkgs.nextcloud27). The installation logic is as follows:- If
services.nextcloud.packageis specified explicitly, this package will be installed (recommended) - If
system.stateVersionis >=23.11,pkgs.nextcloud27will be installed by default. - If
system.stateVersionis >=23.05,pkgs.nextcloud26will be installed by default. - Please note that an upgrade from v25 (or older) to v27 is not possible
directly. Please upgrade to
nextcloud26(or earlier) first. Nextcloud prohibits skipping major versions while upgrading. You may upgrade by declaringservices.nextcloud.package = pkgs.nextcloud26;inbetween.

-
postgresql_11has been removed since it'll stop receiving fixes on November 9th 2023. -
programs.gnupg.agent.pinentryFlavoris set in/etc/gnupg/gpg-agent.confnow. It will no longer take precedence over apinentry-programset in~/.gnupg/gpg-agent.conf. -
python3.pkgs.flitBuildHookhas been removed. Useflit-coreandformat = "pyproject"instead. -
Certificate generation via the
security.acmelimits the concurrent number of running certificate renewals and generation jobs now. This is to avoid spiking resource usage when processing many certificates at once. The limit defaults to 5 and can be adjusted viamaxConcurrentRenewals. Setting the value to 0 disables the limits altogether. -
services.borgmatic.settings.locationandservices.borgmatic.configurations.<name>.locationare deprecated, please move your options out of sections to the global scope. -
services.fail2ban.jailscan be configured with attribute sets now, defining settings and filters instead of lines. The stringed optionsdaemonConfigandextraSettingshave respectively been replaced bydaemonSettingsandjails.DEFAULT.settings. Those use attribute sets. -
The
services.mbpfanmodule has the optionaggressiveenabled by default now. This is for better heat moderation. To get the upstream defaults you may disable this. -
Apptainer/Singularity defaults to using
"$out/var/lib"for theLOCALSTATEDIRconfiguration option instead of the top-level"/var/lib"now. This change impacts theSESSIONDIR(container-run-time mount point) configuration, which is set to$LOCALSTATEDIR/<apptainer or singularity>/mnt/session. This detaches the packages from the top-level directory, rendering the NixOS module optional.The default behavior of the NixOS module
programs.singularitystays unchanged. We add a new optionprograms.singularity.enableExternalSysConfDir(default totrue) to specify whether to set the top-level"/var/lib"asLOCALSTATEDIRor not. -
The
services.sslhmodule has been updated to follow RFC 0042. As such, several options have been moved to the freeform attribute set services.sslh.settings, which allows to change any of the settings in {manpage}sslh(8).In addition, the newly added option services.sslh.method allows to switch between the {manpage}
fork(2), {manpage}select(2)andlibev-based connection handling method. Refer to the sslh docs for a comparison. -
Suricata was upgraded from v6.0 to v7.0 and no longer considers HTTP/2 support as experimental. Refer to upstream release notes for more details.
-
teleporthas been upgraded from major version 12 to major version 14. Refer to upstream upgrade instructions and release notes for v13 and v14. Note that Teleport does not officially support upgrades across more than one major version at a time. If you're running Teleport server components, it is recommended to first upgrade to an intermediate v13.x version by settingservices.teleport.package = pkgs.teleport_13. Afterwards, this option can be removed to upgrade to the default version (14). -
zfswas updated from v2.1.x to v2.2.0, enabling newer kernel support and adding new features. -
The use of
sourceRoot = "source";,sourceRoot = "source/subdir";, and similar lines in package derivations using the defaultunpackPhaseis deprecated as it requiresunpackPhaseto always produce a directory named "source". UsesourceRoot = src.name,sourceRoot = "${src.name}/subdir";, orsetSourceRoot = "sourceRoot=$(echo */subdir)";or similar instead. -
The
djangoalias in the python package set was upgraded to Django v4.x. Applications that consume Django should always pin their python environment to a compatible major version, so they can move at their own pace.{ python = python3.override { packageOverrides = self: super: { django = super.django_3; }; }; } -
The
qemu-vm.nixmodule by default now identifies block devices via persistent names available in/dev/disk/by-*. Because the rootDevice is identified by its filesystem label, it needs to be formatted before the VM is started. The functionality of automatically formatting the rootDevice in the initrd is removed from the QEMU module. However, for tests that depend on this functionality, a test utility for the scripted initrd is added (nixos/tests/common/auto-format-root-device.nix). To use this in a NixOS test, import the module, e.g.imports = [ ./common/auto-format-root-device.nix ];When you use the systemd initrd, you can automatically format the root device by settingvirtualisation.fileSystems."/".autoFormat = true;. -
The
electronpackages places its application files in$out/libexec/electroninstead of$out/lib/electronnow. Packages using electron-builder will fail to build and need to be adjusted by changinglibtolibexec.

Other Notable Changes
-
The new option
system.switch.enablewas added. It is enabled by default. Disabling it makes the system unable to be reconfigured vianixos-rebuild. This is of advantage for image based appliances where updates are handled outside the image. -
services.searxreceives new options for better SearXNG support. This includes options for the built-in rate limiter, bot protection and automatically configuring a local Redis server. -
The iptables firewall module installs the
nixos-firewall-toolnow which allows the user to easily temporarily open ports through the firewall. -
A new option was added to the virtualisation module that enables specifying explicitly named network interfaces in QEMU VMs. The existing
virtualisation.vlansis still supported for cases where the name of the network interface is irrelevant. -
services.outlinecan be configured to use local filesystem storage now. Previously ony S3 storage was possible. This may be set using services.outline.storage.storageType. -
pkgs.openvpn3optionally supports systemd-resolved now.programs.openvpn3will automatically enable systemd-resolved support if services.resolved.enable is set to true. -
The services.woodpecker-server.environmentFile type was changed to list of paths to be more consistent to the woodpecker-agent module
-
services.matrix-synapsehas new options to configure worker processes for matrix-synapse usingservices.matrix-synapse.workers. Configuring a local redis server usingservices.matrix-synapse.configureRedisLocallyis also possible now. -
The
services.nginxmodule gained adefaultListenoption at server-level with support for PROXY protocol listeners. AlsoproxyProtocolis exposed in theservices.nginx.virtualHosts.<name>.listenoption now. This it is possible to run PROXY listeners and non-PROXY listeners at a server-level. Refer to PR #213510 for more details. -
services.restic.backupsadds wrapper scripts to your system path now. This wrapper script sets the same environment variables as the service, so restic operations can easily be run from the command line. This behavior can be disabled by settingcreateWrappertofalse, for each backup configuration. -
services.prometheus.exportershas a new exporter to monitor electrical power consumption based on PowercapRAPL sensor called Scaphandre. Refer to PR #239803 for more details. -
The
services.calibre-servermodule has new options to configure thehost,port,auth.enable,auth.modeandauth.userDbpath. Refer to PR #216497 for more details. -
services.prometheus.exportershas a new exporter to monitor PHP-FPM processes. Refer to PR #240394 for more details. -
services.github-runnerandservices.github-runners.<name>gained the optionnodeRuntimes. This option defaults to[ "node20" ]. I.e., the service supports Node.js 20 GitHub Actions only. The list of Node.js versions accepted bynodeRuntimestracks the versions the upstream GitHub Actions runner supports. Refer to PR #249103 for details. -
programs.gnupghas the optionagent.settingsnow. This allows setting verbatim config values in/etc/gnupg/gpg-agent.conf. -
dockerTools.buildImage,dockerTools.buildLayeredImageanddockerTools.streamLayeredImageuselib.makeOverridablenow . This allowsdockerTools-based images to be customized more efficiently at the Nix level. -
services.influxdb2supports doing an automatic initial setup and provisioning of users, organizations, buckets and authentication tokens now. Refer to PR #249502 for more details. -
wrapHelmexposespassthru.pluginsDirnow which can be passed tohelmfile. For convenience, a top-level packagehelmfile-wrappedhas been added, which inheritspassthru.pluginsDirfromkubernetes-helm-wrapped. Refer to PR #217768 for more details. -
The
boot.initrd.network.udhcp.enableoption allows control over DHCP during Stage 1 regardless of whatnetworking.useDHCPis set to. -
networking.nftableshas the optionnetworking.nftables.table.<table>now. This creates tables and have them be updated atomically, instead of flushing the ruleset. -
hardware.nvidiagaineddatacenteroptions for enabling NVIDIA Data Center drivers and configuration of NVLink/NVSwitch topologies throughnv-fabricmanager. -
The new
boot.bcache.enableoption allows completely removingbcachemount support. It is enabled by default. -
security.sudoprovides two extra options now, while not changing the module's default behaviour:defaultOptionscontrols the options used for the default rules;keepTerminfocontrols whetherTERMINFOandTERMINFO_DIRSare preserved forrootand thewheelgroup.
-
virtualisation.googleComputeImageprovides aefioption to support UEFI booting now. -
CoreDNS may be built with external plugins now. This may be done by overriding
externalPluginsandvendorHasharguments like this:{ services.coredns = { enable = true; package = pkgs.coredns.override { externalPlugins = [ { name = "fanout"; repo = "github.com/networkservicemesh/fanout"; version = "v1.9.1"; } ]; vendorHash = "<SRI hash>"; }; }; }To get the necessary SRI hash, set
vendorHash = "";. The build will fail and produce the correctvendorHashin the error message.If you use this feature, updates to CoreDNS may require updating
vendorHashby following these steps again. -
Using
fusumaenables the following plugins now: appmatcher, keypress, sendkey, tap and wmctrl. -
The Home Assistant module offers support for installing custom components and lovelace modules now. Available at
services.home-assistant.customComponentsandservices.home-assistant.customLovelaceModules. -
TeX Live environments can now be built with the new
texlive.withPackages. The procedure for creating custom TeX packages has been changed. Refer to the Nixpkgs manual for more details. -
In
wxGTK32, the webkit modulewxWebViewhas been enabled on all builds. Prior releases only enabled this on Darwin. -
Support for WiFi6 (IEEE 802.11ax) and WPA3-SAE-PK was enabled in the
hostapdpackage, along with a significant rework of the hostapd module. -
LXD supports virtual machine instances now to complement the existing container support.
-
The
nixos-rebuildcommand has been given alist-generationssubcommand. Refer toman nixos-rebuildfor more details. -
sudo-rs, a reimplementation ofsudoin Rust, is now supported. An experimental new modulesecurity.sudo-rswas added. Switching to it (viasecurity.sudo-rs.enable = true;) introduces slight changes in sudo behaviour, due tosudo-rs' current limitations:- terminfo-related environment variables aren't preserved for
rootandwheel; rootandwheelare not given the ability to set (or preserve) arbitrary environment variables.
Note: The
sudo-rsmodule only takes configuration throughsecurity.sudo-rs, and in particular does not automatically use previously-set rules; this could be achieved withsecurity.sudo-rs.extraRules = security.sudo.extraRules;for instance. - terminfo-related environment variables aren't preserved for
-
There is a new NixOS option when writing NixOS tests
testing.initrdBackdoor, that enablesbackdoor.servicein initrd. Requiresboot.initrd.systemd.enableto be enabled. Boot will pause in Stage 1 atinitrd.target, and will listen for commands from theMachinepython interface, just like Stage 2 normally does. This enables commands to be sent to test and debug Stage 1. Usemachine.switch_root()to leave Stage 1 and proceed to Stage 2. -
The Linux kernel module
msr(refer tomsr(4)), which provides an interface to read and write the model-specific registers (MSRs) of an x86 CPU, can now be configured viahardware.cpu.x86.msr. -
The
qemu-vm.nixmodule now supports disabling overridingfileSystemswithvirtualisation.fileSystems. This enables the user to boot VMs from "external" disk images not created by the qemu-vm module. You can stop the qemu-vm module from overridingfileSystemsby settingvirtualisation.fileSystems = lib.mkForce { };. -
When using split parity files in
snapraid, the snapraid-sync systemd service will no longer fail to run. -
wpa_supplicant's configuration file cannot be read by non-root users, and secrets (such as Pre-Shared Keys) can safely be passed vianetworking.wireless.environmentFile.The configuration file could previously be read, when
userControlled.enable(non-default), by users who are in bothwheelanduserControlled.group(defaults towheel)
Nixpkgs Library
Breaking Changes
lib.lists.foldl'now always evaluates the initial accumulator argument first. If you depend on the lazier behavior, consider usinglib.lists.foldlorbuiltins.foldl'instead.lib.attrsets.foldlAttrsnow always evaluates the initial accumulator argument first.- Now that the internal NixOS transition to Markdown documentation is complete,
lib.options.literalDocBookhas been removed after deprecation in 22.11. lib.types.stringis now fully deprecated and gives a warning when used.
Additions and Improvements
-
lib.fileset: A new sub-library to select local files to use for sources, designed to be easy and safe to use.This aims to be a replacement for
lib.sources-based filtering. To learn more about it, see the blog post or the tutorial. -
lib.gvariant: A partial and basic implementation of GVariant formatted strings. See GVariant Format Strings for details.:::{.warning} This API is not considered fully stable and it might therefore change in backwards incompatible ways without prior notice. :::

Module system:
-
Options in the
optionsmodule argument now have thedeclarationPositionsattribute containing the position where the option was declared:$ nix-repl -f '<nixpkgs/nixos>' [...] nix-repl> :p options.environment.systemPackages.declarationPositions [ { column = 7; file = "/nix/store/vm9zf9wvfd628cchj0hdij1g4hzjrcz9-source/nixos/modules/config/system-path.nix"; line = 62; } ]Not to be confused with
definitionsWithLocations, which is the same but for option definitions. -
Improved error message for option declarations missing
mkOption
Deprecations
lib.meta.getExe pkg(also available aslib.getExe) now gives a warning ifpkg.meta.mainProgramis not set, but it continues to default to the derivation name. Nixpkgs accepts PRs that setmeta.mainProgramon packages where it makes sense. Uselib.getExe' pkg "some-command"to avoid the warning and/or select a different executable.
