Raw Blame History

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.ensurePermissions has been deprecated in favor of services.postgresql.ensureUsers.*.ensureDBOwnership which 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 way GRANT ALL PRIVILEGES is working. services.postgresql.ensurePermissions will be removed in 24.05. All NixOS modules were migrated using one of the strategy, e.g. ensureDBOwnership or postStart. Refer to the PR #266270 for more details.

  • network-online.target has been fixed to no longer time out for systems with networking.useDHCP = true and networking.useNetworkd = true. Workarounds for this can be removed.

  • The boot.loader.raspberryPi options 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.sequoia was removed in favor of python3.pkgs.pysequoia. The latter package is based on upstream's dedicated repository for sequoia's Python bindings, where the Python bindings from gitlab:sequoia-pgp/sequoia were removed long ago.

  • writeTextFile requires executable to be boolean now, values like null or "" will fail to evaluate now.

  • The latest version of clonehero now 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.mastodon doesn't support providing a TCP port to its streaming component 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.streamingProcesses now needs to be declared explicitly.

  • The services.hostapd module was rewritten to support passwordFile like options, WPA3-SAE, and management of multiple interfaces. This breaks compatibility with older configurations.

  • python3.pkgs.fetchPypi and python3Packages.fetchPypi have been deprecated in favor of top-level fetchPypi.

  • 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.config or xdg.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 UseIn key. 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 run G_MESSAGES_DEBUG=all /path/to/xdg-desktop-portal/libexec/xdg-desktop-portal for ideas on which config file and which portals are chosen.

  • pass now does not contain password-store.el. Users should get password-store.el from Emacs lisp package set emacs.pkgs.password-store.

  • services.knot now supports .settings from RFC42. The previous .extraConfig still works the same, but it displays a warning now.

  • services.invoiceplane now supports .settings from RFC42. The previous .extraConfig still works the same way, but it displays a warning now.

  • mu does not install mu4e files by default now. Users should get mu4e from Emacs lisp package set emacs.pkgs.mu4e.

  • mariadb now defaults to mariadb_1011 instead of mariadb_106, meaning the default version was upgraded from v10.6.x to v10.11.x. Refer to the upgrade notes for potential issues.

  • getent has been moved from glibc's bin output to its own dedicated output, reducing closure size for many dependents. Dependents using the getent alias should not be affected; others should move from using glibc.bin or getBin glibc to getent (which also improves compatibility with non-glibc platforms).

  • maintainers/scripts/update-luarocks-packages is now a proper package luarocks-packages-updater that can be run to maintain out-of-tree luarocks packages.

  • The users.users.<name>.passwordFile has been renamed to users.users.<name>.hashedPasswordFile to avoid possible confusions. The option is in fact the file-based version of hashedPassword, not password, and expects a file containing the {manpage}crypt(3) hash of the user password.

  • chromiumBeta and chromiumDev have been removed due to the lack of maintenance in nixpkgs. Consider using chromium instead.

  • google-chrome-beta and google-chrome-dev have been removed due to the lack of maintenance in nixpkgs. Consider using google-chrome instead.

  • The services.ananicy.extraRules option now has the type of listOf attrs instead of string.

  • buildVimPluginFrom2Nix has been renamed to buildVimPlugin, which now now skips configurePhase and buildPhase.

  • JACK tools (jack_* except jack_control) have moved from the jack2 package to jack-example-tools.

  • The waagent service does provisioning now.

  • The matrix-synapse package & module have undergone some significant internal changes, for most setups no intervention is needed, though:

    • The option services.matrix-synapse.package is read-only now. For modifying the package, use an overlay which modifies matrix-synapse-unwrapped instead. More on that below.
    • The enableSystemd & enableRedis arguments have been removed and matrix-synapse has been renamed to matrix-synapse-unwrapped. Also, several optional dependencies (such as psycopg2 or authlib) have been removed.
    • These optional dependencies are automatically added via a wrapper (pkgs.matrix-synapse.override { extras = ["redis"]; } for hiredis & txredisapi for instance) if the relevant config section is declared in services.matrix-synapse.settings. For instance, if services.matrix-synapse.settings.redis.enabled is set to true, "redis" will be automatically added to the extras list of pkgs.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 PYTHONPATH of matrix-synapse.service's environment to have all plugins available. This isn't necessary anymore, instead config.services.matrix-synapse.package can be used as it points to the wrapper with properly configured extras and also all plugins defined via services.matrix-synapse.plugins available. This is also the reason for why the option is read-only now, it's supposed to be set by the module only.

  • netbox was updated to v3.6. services.netbox.package still defaults to v3.5 if stateVersion is earlier than 23.11. Refer to upstream's breaking changes for v3.6.0 and upgrade NetBox by changing services.netbox.package. Database migrations will be run automatically.

  • etcd has been updated to v3.5. Refer to upgrade guides for v3.3 to v3.4 and v3.4 to v3.5 for more details.

  • gitlab installations created or updated between versions [15.11.0, 15.11.2] have an incorrect database schema. This will become a problem when upgrading to gitlab >=16.2.0. A workaround for affected users can be found in the GitLab docs.

  • consul has 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_rocm has been moved to rocmPackages.llvm.

  • hip, rocm-opencl-runtime, rocm-opencl-icd, and rocclr have been combined into rocmPackages.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, and tensile have been moved to rocmPackages.

  • himalaya has 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-git now ignores global and user git config, to improve reproducibility.

  • The services.caddy.acmeCA option defaults to null instead 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.phpOptions have 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 of phpOptions are still defaults, these can be overridden as shown here.

    To override all of the options (including including upload_max_filesize, post_max_size and memory_limit which all point to services.nextcloud.maxUploadSize by default) can be done like this:

    {
  services.nextcloud.phpOptions = lib.mkForce {
    /* ... */
  };
}

  • php80 is 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 like llvm-installable-svm and native-image-svm were 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-exporter has been replaced by the Let's Encrypt maintained version, since the previous version was archived. This requires some changes to the module configuration, most notable controlInterface needs migration towards unbound.host and requires either the tcp:// or unix:// URI scheme.

  • odoo defaults to v16 now, updated from v15.

  • varnish was 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 as varnish60.

  • util-linux is now supported on Darwin and is no longer an alias to unixtools. Use the unixtools.util-linux package for access to the Apple variants of the utilities.

  • services.keyd changed 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 vlock program from the kbd package has been moved into its own package output and should now be referenced explicitly as kbd.vlock or replaced with an alternative such as the standalone vlock package or physlock.

  • fileSystems.<name>.autoFormat now uses systemd-makefs, which does not accept formatting options. Therefore, fileSystems.<name>.formatOptions has been removed.

  • fileSystems.<name>.autoResize uses systemd-growfs to resize the file system online in Stage 2 now. This means that f2fs and ext2 can no longer be auto resized, while xfs and btrfs now can be.

  • fuse3 has 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 atime

    would 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 inside systemd-run now, 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 the NIXOS_SWITCH_USE_DIRTY_ENV environment variable before running nixos-rebuild. However, keep in mind that this option will be removed in the future.

  • The services.vaultwarden.config option default value was changed to make Vaultwarden only listen on localhost, following the secure defaults for most NixOS services.

  • services.lemmy.settings.federation was 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-rs was upgraded from v0.3 to v0.4 and contains an incompatible database & configuration change. To upgrade on systems with stateVersion = "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 set services.pict-rs.package = pkgs.pict-rs;.

  • The following packages in haskellPackages have 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. via ghcWithPackages. environment.packages picks the bin output automatically, so for normal installation no intervention is required. Also, toplevel attributes like pkgs.nixfmt are not impacted negatively by this change.

  • spamassassin no longer supports the Hashcash module. The module needs to be removed from the loadplugin list if it was copied over from the default initPreConf option.

  • nano was removed from environment.defaultPackages. To not leave systems without a editor, now programs.nano.enable is enabled by default.

  • programs.nano.nanorc and programs.nano.syntaxHighlight no longer have an effect unless programs.nano.enable is set to true which is the default.

  • services.outline.sequelizeArguments has been removed, as outline no longer executes database migrations via the sequelize cli.

  • The binary of the package cloud-sql-proxy has changed from cloud_sql_proxy to cloud-sql-proxy.

  • The module services.apache-kafka was 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.
      • Care must be taken when adapting an existing cluster to these changes, see .
    • 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.

  • Garage has been upgraded to v0.9.x. services.garage.package needs to be explicitly set now, so version upgrades can be done in a controlled fashion. For this, we expose garage_x_y attributes which can be set here.

  • voms and xrootd now moves the $out/etc content to the $etc output instead of $out/etc.orig, when input argument externalEtc is not null.

  • 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.enableReload which is enabled by default. It allows reloading the service instead of restarting it, if only a config file has changed. This option must be disabled if you have turned off the Caddy admin API. If you keep this option enabled, you should consider setting grace_period to 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 by nixos-generate-config when installing to a software RAID device, so the standard installation procedure should be unaffected. If you have custom configs relying on mdraid, ensure that you use stateVersion correctly or set boot.swraid.enable manually. On systems with an updated stateVersion we now also emit warnings if mdadm.conf does not contain the minimum required configuration necessary to run the dynamically enabled monitoring daemons.

  • The go-ethereum package 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 from leveldb to pebble but leveldb can be forced with the --db.engine=leveldb flag. The checkpoint-admin command was removed along with trusted checkpoints.

  • The aseprite-unfree package 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 the libresprite package.

  • The default kops version is v1.28.0 now and support for v1.25 and older have been dropped.

  • pharo has 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 severily outdated. Finally, the pharo-launcher package 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-sitter support (enabled by default) and the pgtk variant (useful for Wayland users), which is available under the attribute emacs29-pgtk.

  • Emacs macport version 29 was introduced.

  • The option services.networking.networkmanager.enableFccUnlock was removed in favor of networking.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-proofer package has been updated from major version 3 to major version 5, which includes breaking changes.

  • kratos has 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 from link to code.

  • The hail module was removed, as hail was unmaintained since 2017.

  • Package noto-fonts-emoji was renamed to noto-fonts-color-emoji. Refer to PR #221181 for more details.

  • Package cloud-sql-proxy was renamed to google-cloud-sql-proxy as it cannot be used with other cloud providers.

  • Package pash was removed due to being archived upstream. Use powershell as an alternative.

  • The option services.plausible.releaseCookiePath has 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 that releaseCookiePath was set to.

  • security.sudo.extraRules includes root's default rule now, with ordering priority 400. This is functionally identical for users not specifying rule order, or relying on mkBefore and mkAfter, but may impact users calling mkOrder n with n ≤ 400.

  • X keyboard extension (XKB) options have been reorganized into a single attribute set, services.xserver.xkb. Specifically, services.xserver.layout is services.xserver.xkb.layout now, services.xserver.extraLayouts is services.xserver.xkb.extraLayouts now, services.xserver.xkbModel is services.xserver.xkb.model now, services.xserver.xkbOptions is services.xserver.xkb.options now , services.xserver.xkbVariant is services.xserver.xkb.variant now, and services.xserver.xkbDir is services.xserver.xkb.dir now.

  • networking.networkmanager.firewallBackend was removed as NixOS is now using iptables-nftables-compat even when using iptables, therefore Networkmanager uses the nftables backend unconditionally now.

  • rome was removed because it is no longer maintained and is succeeded by biome.

  • The prometheus-knot-exporter was migrated to a version maintained by CZ.NIC. Various metric names have changed, so checking existing rules is recommended.

  • The services.mtr-exporter.target has been removed in favor of services.mtr-exporter.jobs which allows specifying multiple targets.

  • blender-with-packages has been deprecated in favor of blender.withPackages, for example blender.withPackages (ps: [ps.bpycv]). It behaves similarly to python3.withPackages.

  • Setting nixpkgs.config options while providing an external pkgs instance will now raise an error instead of silently ignoring the options. NixOS modules no longer set nixpkgs.config to accommodate this. This specifically affects services.locate, services.xserver.displayManager.lightdm.greeters.tiny and programs.firefox NixOS 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 corresponding privacyidea-ldap-proxy) has been removed from nixpkgs because it has severely outdated dependencies that became unmaintainable with nixpkgs' python package-set.

  • dagger was removed because using a package called dagger and packaging it from source violates their trademark policy.

  • win-virtio package was renamed to virtio-win to be consistent with the upstream package name.

  • ps3netsrv has been replaced with the webman-mod fork, the executable has been renamed from ps3netsrv++ to ps3netsrv and cli parameters have changed.

  • ssm-agent package and module were renamed to amazon-ssm-agent to be consistent with the upstream package name.

  • services.kea.{ctrl-agent,dhcp-ddns,dhcp,dhcp6} now use separate runtime directories instead of /run/kea to work around the runtime directory being cleared on service start.

  • mkDerivation rejects MD5 hashes now.

  • The junicode font package has been updated to major v2, which is a font family now. In particular, plain Junicode.ttf no longer exists. In addition, TrueType font files are now placed in font/truetype instead of font/junicode-ttf; this change does not affect use via fonts.packages option.

  • The prayer package as well as services.prayer have been removed because it's been unmaintained for several years and the author's website has vanished.

  • The chrony NixOS module now tracks the real-time clock drift from the system clock with rtcfile and automatically adjusts it with rtcautotrim when it exceeds the maximum error specified in services.chrony.autotrimThreshold (defaults to 30 seconds). If you enabled rtcsync in extraConfig, you should remove RTC related options from extraConfig. If you do not want chrony configured to keep the RTC in check, you can set services.chrony.enableRTCTrimming = false;.

  • trilium-desktop and trilium-server have 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_bcachefs is now soft-deprecated by linuxPackages_testing.

    • Please consider changing your NixOS configuration's boot.kernelPackages to linuxPackages_testing until a stable kernel with bcachefs support is released.

  • 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.

  • systemd has been updated from v253 to v254, refer to the release notes for more details.

    • boot.resumeDevice must 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 boot and rebooting is recommended, since in some rare cases the nixos-rebuild switch into 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 = ${CUSTOMSHELL}, the assertion will require them to also set programs.${CUSTOMSHELL}.enable = true. This is generally safe behavior, but for anyone needing to opt out from the check users.users.${USERNAME}.ignoreShellProgramCheck = true will do the job.

  • yarn-berry has 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.ankisyncd has 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 vendorSha256 of buildGoModule is deprecated. Use vendorHash instead. Refer to PR #259999) for more details.

  • go-modules in buildGoModule attrs has been renamed to goModules.

  • The package cawbird is 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 extend function of llvmPackages has been removed due it coming from the tools attrset thus only extending the tool attrset. A possible replacement is to construct the set from libraries and tools, or patch nixpkgs.

  • ffmpeg defaults to ffmpeg_6 now, upgrading from ffmpeg_5.

  • fontconfig defaults 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.fonts and fonts.enableDefaultFonts options have been renamed to fonts.packages and fonts.enableDefaultPackages respectively.

  • services.hedgedoc has 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.

  • jq was updated to v1.7. This is its first release in 5 years.

  • lib.attrsets.foldlAttrs now 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 using lib.lists.foldl or builtins.foldl' instead.

  • Now magma defaults to magma-hip instead of magma-cuda. It also respects the config.cudaSupport and config.rocmSupport options.

  • 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 netdata package disables cloud support by default now. To enable it use the netdataCloud package.

  • networking.nftables is no longer flushing all rulesets on every reload. Use networking.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 opensnitch uses 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.

  • paperwork is 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:

  • postgresql_11 has been removed since it'll stop receiving fixes on November 9th 2023.

  • programs.gnupg.agent.pinentryFlavor is set in /etc/gnupg/gpg-agent.conf now. It will no longer take precedence over a pinentry-program set in ~/.gnupg/gpg-agent.conf.

  • python3.pkgs.flitBuildHook has been removed. Use flit-core and format = "pyproject" instead.

  • Certificate generation via the security.acme limits 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 via maxConcurrentRenewals. Setting the value to 0 disables the limits altogether.

  • services.borgmatic.settings.location and services.borgmatic.configurations.<name>.location are deprecated, please move your options out of sections to the global scope.

  • services.fail2ban.jails can be configured with attribute sets now, defining settings and filters instead of lines. The stringed options daemonConfig and extraSettings have respectively been replaced by daemonSettings and jails.DEFAULT.settings. Those use attribute sets.

  • The services.mbpfan module has the option aggressive enabled 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 the LOCALSTATEDIR configuration option instead of the top-level "/var/lib" now. This change impacts the SESSIONDIR (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.singularity stays unchanged. We add a new option programs.singularity.enableExternalSysConfDir (default to true) to specify whether to set the top-level "/var/lib" as LOCALSTATEDIR or not.

  • The services.sslh module 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) and libev-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.

  • teleport has 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 setting services.teleport.package = pkgs.teleport_13. Afterwards, this option can be removed to upgrade to the default version (14).

  • zfs was 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 default unpackPhase is deprecated as it requires unpackPhase to always produce a directory named "source". Use sourceRoot = src.name, sourceRoot = "${src.name}/subdir";, or setSourceRoot = "sourceRoot=$(echo */subdir)"; or similar instead.

  • The django alias 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.nix module 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 setting virtualisation.fileSystems."/".autoFormat = true;.

  • The electron packages places its application files in $out/libexec/electron instead of $out/lib/electron now. Packages using electron-builder will fail to build and need to be adjusted by changing lib to libexec.

New Services

Other Notable Changes

  • The new option system.switch.enable was added. It is enabled by default. Disabling it makes the system unable to be reconfigured via nixos-rebuild. This is of advantage for image based appliances where updates are handled outside the image.

  • services.searx receives 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-tool now 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.vlans is still supported for cases where the name of the network interface is irrelevant.

  • services.outline can be configured to use local filesystem storage now. Previously ony S3 storage was possible. This may be set using services.outline.storage.storageType.

  • pkgs.openvpn3 optionally supports systemd-resolved now. programs.openvpn3 will 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-synapse has new options to configure worker processes for matrix-synapse using services.matrix-synapse.workers. Configuring a local redis server using services.matrix-synapse.configureRedisLocally is also possible now.

  • The services.nginx module gained a defaultListen option at server-level with support for PROXY protocol listeners. Also proxyProtocol is exposed in the services.nginx.virtualHosts.<name>.listen option 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.backups adds 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 setting createWrapper to false, for each backup configuration.

  • services.prometheus.exporters has a new exporter to monitor electrical power consumption based on PowercapRAPL sensor called Scaphandre. Refer to PR #239803 for more details.

  • The services.calibre-server module has new options to configure the host, port, auth.enable, auth.mode and auth.userDb path. Refer to PR #216497 for more details.

  • services.prometheus.exporters has a new exporter to monitor PHP-FPM processes. Refer to PR #240394 for more details.

  • services.github-runner and services.github-runners.<name> gained the option nodeRuntimes. This option defaults to [ "node20" ]. I.e., the service supports Node.js 20 GitHub Actions only. The list of Node.js versions accepted by nodeRuntimes tracks the versions the upstream GitHub Actions runner supports. Refer to PR #249103 for details.

  • programs.gnupg has the option agent.settings now. This allows setting verbatim config values in /etc/gnupg/gpg-agent.conf.

  • dockerTools.buildImage, dockerTools.buildLayeredImage and dockerTools.streamLayeredImage use lib.makeOverridable now . This allows dockerTools-based images to be customized more efficiently at the Nix level.

  • services.influxdb2 supports doing an automatic initial setup and provisioning of users, organizations, buckets and authentication tokens now. Refer to PR #249502 for more details.

  • wrapHelm exposes passthru.pluginsDir now which can be passed to helmfile. For convenience, a top-level package helmfile-wrapped has been added, which inherits passthru.pluginsDir from kubernetes-helm-wrapped. Refer to PR #217768 for more details.

  • The boot.initrd.network.udhcp.enable option allows control over DHCP during Stage 1 regardless of what networking.useDHCP is set to.

  • networking.nftables has the option networking.nftables.table.<table> now. This creates tables and have them be updated atomically, instead of flushing the ruleset.

  • hardware.nvidia gained datacenter options for enabling NVIDIA Data Center drivers and configuration of NVLink/NVSwitch topologies through nv-fabricmanager.

  • The new boot.bcache.enable option allows completely removing bcache mount support. It is enabled by default.

  • security.sudo provides two extra options now, while not changing the module's default behaviour:

    • defaultOptions controls the options used for the default rules;
    • keepTerminfo controls whether TERMINFO and TERMINFO_DIRS are preserved for root and the wheel group.

  • virtualisation.googleComputeImage provides a efi option to support UEFI booting now.

  • CoreDNS may be built with external plugins now. This may be done by overriding externalPlugins and vendorHash arguments 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 correct vendorHash in the error message.

    If you use this feature, updates to CoreDNS may require updating vendorHash by following these steps again.

  • Using fusuma enables 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.customComponents and services.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 module wxWebView has 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 hostapd package, along with a significant rework of the hostapd module.

  • LXD supports virtual machine instances now to complement the existing container support.

  • The nixos-rebuild command has been given a list-generations subcommand. Refer to man nixos-rebuild for more details.

  • sudo-rs, a reimplementation of sudo in Rust, is now supported. An experimental new module security.sudo-rs was added. Switching to it (via security.sudo-rs.enable = true;) introduces slight changes in sudo behaviour, due to sudo-rs' current limitations:

    • terminfo-related environment variables aren't preserved for root and wheel;
    • root and wheel are not given the ability to set (or preserve) arbitrary environment variables.

    Note: The sudo-rs module only takes configuration through security.sudo-rs, and in particular does not automatically use previously-set rules; this could be achieved with security.sudo-rs.extraRules = security.sudo.extraRules; for instance.

  • There is a new NixOS option when writing NixOS tests testing.initrdBackdoor, that enables backdoor.service in initrd. Requires boot.initrd.systemd.enable to be enabled. Boot will pause in Stage 1 at initrd.target, and will listen for commands from the Machine python interface, just like Stage 2 normally does. This enables commands to be sent to test and debug Stage 1. Use machine.switch_root() to leave Stage 1 and proceed to Stage 2.

  • The Linux kernel module msr (refer to msr(4)), which provides an interface to read and write the model-specific registers (MSRs) of an x86 CPU, can now be configured via hardware.cpu.x86.msr.

  • The qemu-vm.nix module now supports disabling overriding fileSystems with virtualisation.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 overriding fileSystems by setting virtualisation.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 via networking.wireless.environmentFile.

    The configuration file could previously be read, when userControlled.enable (non-default), by users who are in both wheel and userControlled.group (defaults to wheel)

Nixpkgs Library

Breaking Changes

  • lib.lists.foldl' now always evaluates the initial accumulator argument first. If you depend on the lazier behavior, consider using lib.lists.foldl or builtins.foldl' instead.
  • lib.attrsets.foldlAttrs now always evaluates the initial accumulator argument first.
  • Now that the internal NixOS transition to Markdown documentation is complete, lib.options.literalDocBook has been removed after deprecation in 22.11.
  • lib.types.string is now fully deprecated and gives a warning when used.

Additions and Improvements

Module system:

  • Options in the options module argument now have the declarationPositions attribute 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 as lib.getExe) now gives a warning if pkg.meta.mainProgram is not set, but it continues to default to the derivation name. Nixpkgs accepts PRs that set meta.mainProgram on packages where it makes sense. Use lib.getExe' pkg "some-command" to avoid the warning and/or select a different executable.
