Raw Blame History

Release 24.11 (“Vicuña”, 2024.11/??)

Highlights

  • This will be the last release of Nixpkgs to support macOS Sierra 10.12 to macOS Catalina 10.15. Starting with release 25.05, the minimum supported version will be macOS Big Sur 11, and we cannot guarantee that packages will continue to work on older versions of macOS. Users on old macOS versions should consider upgrading to a supported version (potentially using OpenCore Legacy Patcher for old hardware) or installing NixOS. If neither of those options are viable and you require new versions of software, MacPorts supports back to Mac OS X Snow Leopard 10.6.

  • Nix was updated to 2.24, which brings a lot of improvements and fixes. See the release notes for 2.19, 2.20, 2.21, 2.22, 2.23, 2.24. Notable changes include improvements to Git fetching, documentation comment support in nix-repl> :doc, as well as many quality of life improvements.

  • This will be the last release of Nixpkgs to support versions of CUDA prior to CUDA 12.0. These versions only work with old compiler versions that will be unsupported by the time of the Nixpkgs 25.05 release. In future, users should expect CUDA versions to be dropped as the compiler versions they require leave upstream support windows.

  • Convenience options for amdgpu, open source driver for Radeon cards, is now available under hardware.amdgpu.

  • AMDVLK, AMD's open source Vulkan driver, is now available to be configured as hardware.amdgpu.amdvlk option. This also allows configuring runtime settings of AMDVLK and enabling experimental features.

  • The moonlight-qt package (Moonlight game streaming) now has HDR support on Linux systems.

  • PostgreSQL now defaults to major version 16.

  • authelia has been upgraded to version 4.38. This version brings several features and improvements which are detailed in the release blog post. This release also deprecates some configuration keys, which are likely to be removed in future version 5.0, but they are still supported and expected to be working in the current version.

  • compressDrv can compress selected files in a derivation. compressDrvWeb compresses files for common web server usage (.gz with zopfli, .br with brotli).

  • hardware.display is a new module implementing workarounds for misbehaving monitors through setting up custom EDID files and forcing kernel/framebuffer modes.

  • A new display-manager services.displayManager.ly was added. It is a tui based replacement of sddm and lightdm for window manager users. Users can use it by services.displayManager.ly.enable and config it by services.displayManager.ly.settings to generate /etc/ly/config.ini

  • The default sound server for most graphical sessions has been switched from PulseAudio to PipeWire. Users that want to keep PulseAudio will want to set services.pipewire.enable = false; and hardware.pulseaudio.enable = true;. There is currently no plan to fully deprecate and remove PulseAudio, however, PipeWire should generally be preferred for new installs.

  • The Rust rewrite of the switch-to-configuration program is now used for system activation by default. If you experience any issues, please report them. The original Perl script is deprecated and is planned for removal in the 25.05 release. It will remain accessible until then by setting system.switch.enableNg to false.

  • Built NixOS configurations now have a $toplevel/bin/apply script. Unlike switch-to-configuration, it is capable of performing a complete switch operation. If you call switch-to-configuration directly, you are recommended to use apply instead, and remove your call to nix-env --profile /nix/var/nix/profiles/system --set $toplevel or similar. It will run the switch operation as a systemd unit if available, as nixos-rebuild switch would.

    Benefits include:

    • The apply script reduces the roundtrips required when performing a remote deployment with nixos-rebuild switch --target-host HOST.
    • Developers and power users can now update NixOS in a single call.
    • Alternative NixOS deployment methods have feature parity with nixos-rebuild, and NixOS can evolve all of its switching logic in one place.

  • Support for mounting filesystems from block devices protected with dm-verity was added through the boot.initrd.systemd.dmVerity option.

  • The Xen Project Hypervisor is once again available as a virtualisation option under virtualisation.xen.

    • This release includes Xen 4.19.0 and support for booting the hypervisor on EFI systems. ::: {.warning} Booting into the Xen Project Hypervisor through a legacy BIOS bootloader or with the legacy script-based Stage 1 initrd have been deprecated. Only EFI booting and the new systemd-based Stage 1 initrd are supported. :::
    • The qemu-xen-traditional component has been deprecated by the upstream Xen Project, and is no longer included in the Xen build.
    • The OCaml-based Xen Store can now be configured using virtualisation.xen.store.settings.
    • The virtualisation.xen.bridge options have been deprecated in this release cycle. Users who need network bridges are encouraged to set up their own networking configurations.

  • A new option systemd.enableStrictShellChecks has been added. When enabled, all systemd scripts generated by NixOS will be checked with shellcheck and any errors or warnings will cause the build to fail. This affects all scripts that have been created through the script, reload, preStart, postStart, preStop and postStop options for systemd services. This does not affect commandlines passed directly to ExecStart, ExecReload, ExecStartPre, ExecStartPost, ExecStop or ExecStopPost. It therefore also does not affect systemd units that are coming from packages and that are not defined through the NixOS config. This option is disabled by default, and although some services have already been fixed, it is still likely that you will encounter build failures when enabling this. We encourage people to enable this option when they are willing and able to submit fixes for potential build failures to nixpkgs. The option can also be enabled or disabled for individual services using the enableStrictShellChecks option on the service itself, which will take precedence over the global setting.

New Modules

Backward Incompatibilities

  • The sound options have been removed or renamed, as they had a lot of unintended side effects. See below for details.

  • The nvidia driver no longer defaults to the proprietary driver starting with version 560. You will need to manually set hardware.nvidia.open to select the proprietary or open driver.

  • The (buildPythonPackage { ... }).override attribute is now deprecated and removed in favour of overridePythonAttrs. This change does not affect the override interface of most Python packages, as <pkg>.override provided by callPackage shadows such a locally-defined override attribute.

  • All Cinnamon and XApp packages have been moved to top-level (i.e., cinnamon.nemo is now nemo).

  • All GNOME packages have been moved to top-level (i.e., gnome.nautilus is now nautilus).

  • transmission package has been aliased with a trace warning to transmission_3. Since Transmission 4 has been released last year, and Transmission 3 will eventually go away, it was decided perform this warning alias to make people aware of the new version. The services.transmission.package defaults to transmission_3 as well because the upgrade can cause data loss in certain specific usage patterns (examples: #5153, #6796). Please make sure to back up to your data directory per your usage:

    • transmission-gtk: ~/.config/transmission
    • transmission-daemon using NixOS module: ${config.services.transmission.home}/.config/transmission-daemon (defaults to /var/lib/transmission/.config/transmission-daemon)

  • The default mongodb version has been updated from 5.0 to 7.0. For more information, see the compatibility changes for MongoDB 6.0 and 7.0.

  • unifi has been updated to UniFi 8. unifi7 was removed as it is vulnerable to CVE-2024-42025 and required a version of MongoDB that has reached end of life.

  • androidenv.androidPkgs_9_0 has been removed, and replaced with androidenv.androidPkgs for a more complete Android SDK including support for Android 9 and later.

  • grafana has been updated to version 11.1. This version doesn't support setting http_addr to a hostname anymore, an IP address is expected.

  • deno has been updated to v2 which has breaking changes. Upstream will be abandoning v1 soon but for now you can use deno_1 if you are yet to migrate (will be removed prior to cutting a final 24.11 release).

  • gogs has been removed. Upstream development has stalled and it has several critical vulnerabilities that weren't addressed within a year. Consider migrating to forgejo or gitea.

  • knot-dns has been updated to version 3.4.x. Check the migration guide for breaking changes.

  • services.kubernetes.kubelet.clusterDns now accepts a list of DNS resolvers rather than a single string, bringing the module more in line with the upstream Kubelet configuration schema.

  • bluemap has changed the format used to store map tiles, and the database layout has been heavily modified. Upstream recommends a clean reinstallation: https://github.com/BlueMap-Minecraft/BlueMap/releases/tag/v5.2. Unless you are using an SQL storage backend, this should only entail deleting the contents of config.services.bluemap.coreSettings.data (defaults to /var/lib/bluemap) and config.services.bluemap.webRoot (defaults to /var/lib/bluemap/web).

  • wstunnel has had a major version upgrade that entailed rewriting the program in Rust. The module was updated to accommodate for breaking changes. Breaking changes to the module API were minimised as much as possible, but some were nonetheless inevitable due to changes in the upstream CLI. Certain options were moved from separate CLI arguments into the forward specifications, and those options were also removed from the module's API, please consult the wstunnel man page for more detail. Also be aware that if you have set additional options in services.wstunnel.{clients,servers}.<name>.extraArgs, that those might have been removed or modified upstream.

  • percona-server_8_4 and mysql84 now have password authentication via the deprecated mysql_native_password disabled by default. This authentication plugin can be enabled via a CLI argument again, for detailed instructions and alternative authentication methods see upstream documentation. The config file directive default_authentication_plugin has been removed.

  • Percona has decided not to follow the LTS/ Innovation release scheme of upstream MySQL and thus will only create releases for MySQL LTS versions. Hence, the package names percona-server_lts, percona-server_innovation, percona-xtrabackup_lts and percona-xtrabackup_innovation are deprecated.

    • percona-server and percona-server_lts now point towards the new LTS release percona-server_8_4. The previous LTS continues to be supported and is available as percona-server_8_0. The same is true for the supporting percona-xtrabackup tooling.

  • clang-tools_<version> packages have been moved into llvmPackages_<version> (i.e. clang-tools_18 is now llvmPackages_18.clang-tools).

    • For convenience, the top-level clang-tools attribute remains and is now bound to llvmPackages.clang-tools.
    • Top-level clang_tools_<version> attributes are now aliases; these will be removed in a future release.

  • buildbot was updated to 4.0, the AngularJS frontend has been replaced by a React frontend, see the upstream release notes.

  • headscale has been updated to version 0.23.0 which reworked large parts of the configuration including DNS, Magic DNS prefixes and ACL policy files. See the upstream changelog for details.

  • nginx package no longer includes gd and geoip dependencies. For enabling it, override nginx package with the optionals withImageFilter and withGeoIP.

  • systemd.enableUnifiedCgroupHierarchy option has been removed. In systemd 256 support for cgroup v1 ('legacy' and 'hybrid' hierarchies) is now considered obsolete and systemd by default will refuse to boot under it. To forcibly reenable cgroup v1 support, you can set boot.kernelParams = [ "systemd.unified_cgroup_hierachy=0" "SYSTEMD_CGROUP_ENABLE_LEGACY_FORCE=1" ]. NixOS does not officially support this configuration and might cause your system to be unbootable in future versions. You are on your own.

  • nrfutil which previously pointed to the now-deprecated pc-nrfutil python package, has been repackaged under the same name with the new nrfutil tool.

  • openssh and openssh_hpn are now compiled without Kerberos 5 / GSSAPI support in an effort to reduce the attack surface of the components for the majority of users. Users needing this support can use the new opensshWithKerberos and openssh_hpnWithKerberos flavors (e.g. programs.ssh.package = pkgs.openssh_gssapi).

  • security.ipa.ipaHostname now defaults to the value of networking.fqdn if it is set, instead of the previous hardcoded default of ${networking.hostName}.${security.ipa.domain}.

  • The MSMTP_QUEUE and MSMTP_LOG environment variables accepted by msmtpq have now been renamed to MSMTPQ_Q and MSMTPQ_LOG respectively.

  • The logrotate service has received hardening and now requires enabling allowNetworking, if logrotate needs to access the network.

  • mautrix-whatsapp has been updated to version 0.11.0, which is a major rewrite of the bridge. Config file changes are required.

  • qBittorrent has been updated to major version 5, which drops support for Qt 5. The qbittorrent-qt5 package has been removed.

  • The fcgiwrap module now allows multiple instances running as distinct users. The option services.fgciwrap now takes an attribute set of the configuration of each individual instance. This requires migrating any previous configuration keys from services.fcgiwrap.* to services.fcgiwrap.instances.some-instance.*. The ownership and mode of the UNIX sockets created by this service are now configurable and private by default. Processes also now run as a dynamically allocated user by default instead of root.

  • The mautrix-signal module was adapted to incorporate the configuration rearrangement that resulted from the update to the mautrix bridgev2 architecture. Pre-0.7.0 configurations should continue to work. In case you want to update your configuration make sure to check the NixOS manual.

  • The dhcpcd service (networking.useDHCP) has been hardened and now runs exclusively as the "dhcpcd" user. Users that were relying on the root privileges in networking.dhcpcd.runHook will have to write specific sudo or polkit rules to allow dhcpcd to perform privileged actions.

    As part of these changes, the DHCP lease files directory has also been moved from /var/db/dhcpcd to /var/lib/dhcpcd. This migration is performed automatically, but users may have to update their backup configuration.

  • singularity-tools have the storeDir argument removed from its override interface and use builtins.storeDir instead.

  • Two build helpers in singularity-tools, i.e., mkLayer and shellScript, are deprecated, as they are no longer involved in image-building. Maintainers will remove them in future releases.

  • The rust.toTargetArch, rust.toTargetOs, rust.toTargetFamily, rust.toTargetVendor, rust.toRustTarget, rust.toRustTargetSpec, rust.toRustTargetSpecShort, and rust.IsNoStdTarget functions are deprecated in favour of the rust.platform.arch, rust.platform.os, rust.platform.target-family, rust.platform.vendor, rust.rustcTarget, rust.rustcTargetSpec, rust.cargoShortTarget, rust.cargoEnvVarTarget, and rust.isNoStdTarget platform attributes respectively.

  • The budgie and budgiePlugins scope have been removed and their packages moved into the top level scope (i.e., budgie.budgie-desktop is now budgie-desktop)

  • The method to safely handle secrets in the networking.wireless module has been changed to benefit from a new feature of wpa_supplicant. The syntax to refer to secrets has changed slightly and the option networking.wireless.environmentFile has been replaced by networking.wireless.secretsFile; see the description of the latter for how to upgrade.

  • NetBox was updated to >= 4.1.0. Have a look at the breaking changes of the 4.0 release and the 4.1 release, make the required changes to your database, if needed, then upgrade by setting services.netbox.package = pkgs.netbox_4_1; in your configuration.

  • services.cgit now runs as the cgit user by default instead of root. This change requires granting access to the repositories to this user or setting the appropriate one through services.cgit.some-instance.user.

  • nvimpager was updated to version 0.13.0, which changes the order of user and nvimpager settings: user commands in -c and --cmd now override the respective default settings because they are executed later.

  • Kubernetes featureGates have changed from a listOf str to attrsOf bool. This refactor makes it possible to also disable feature gates, without having to use extraOpts flags.

    A previous configuration may have looked like this:

    featureGates = [ "EphemeralContainers" ];
extraOpts = pkgs.lib.concatStringsSep " " (
[
  ''--feature-gates="CSIMigration=false"''
});

    Using an AttrSet instead, the new configuration would be:

    featureGates = {EphemeralContainers = true; CSIMigration=false;};

  • pkgs.nextcloud27 has been removed since it's EOL.

  • The environment.noXlibs option has been removed. It was a common source of unexpected rebuilds and breakage that was often hard to diagnose. If you need to disable certain libraries, you're encouraged to add your own overlay to your configuration that targets the packages you care about.

  • frigate was updated past 0.14.0. This release includes various breaking changes, so please go read the release notes. Most prominently access to the webinterface and API are now protected by authentication. Retrieve the auto-created admin account from the frigate.service journal after upgrading.

  • nodePackages.coc-python was dropped, as its upstream is unmaintained. The associated vimPlugins.coc-python was also dropped. The upstream project recommends using coc-pyright or coc-jedi as replacements.

  • forgejo has been upgraded from version 7.0 to version 9.0, see the release notes for 8.0 and 9.0.

  • services.forgejo.mailerPasswordFile has been deprecated by the drop-in replacement services.forgejo.secrets.mailer.PASSWD, which is part of the new free-form services.forgejo.secrets option. services.forgejo.secrets is a small wrapper over systemd's LoadCredential=. It has the same structure (sections/keys) as services.forgejo.settings but takes file paths that will be read before service startup instead of some plaintext value. services.forgejo.package now defaults to forgejo-lts, the Long Term Support version of Forgejo.

  • forgejo and forgejo-lts no longer support the opt-in feature PAM (Pluggable Authentication Module).

  • gitea no longer supports the opt-in feature PAM (Pluggable Authentication Module).

  • services.ddclient.use has been deprecated: ddclient now supports separate IPv4 and IPv6 configuration. Use services.ddclient.usev4 and services.ddclient.usev6 instead.

  • services.pgbouncer systemd service is configured with Type=notify-reload and allows reloading configuration without process restart. PgBouncer configuration options were moved to the free-form type option named services.pgbouncer.settings according to the NixOS RFC 0042.

  • nodePackages.coc-metals was removed due to being deprecated upstream. vimPlugins.nvim-metals is its official replacement.

  • matrix-sliding-sync was removed because it has been replaced by the simplified sliding sync functionality introduced in matrix-synapse 114.0.

  • nodePackages.coc-tslint, vimPlugins.coc-tslint, nodePackages.coc-tslint-plugin, and vimPlugins.coc-tslint-plugin were removed due to being deprecated upstream. The nodePackages.coc-eslint and vimPlugins.coc-eslint packages offer comparable features for eslint, which replaced tslint.

  • Tcl packages have been moved into the tclPackages scope.

  • teleport has been upgraded from major version 15 to major version 16. Refer to upstream upgrade instructions and release notes for v16.

  • tests.overriding has its passthru.tests restructured as an attribute set instead of a list, making individual tests accessible by their names.

  • Package skk-dict was split into multiple packages under skkDictionaries. If in doubt, try skkDictionaries.l. As part of this change, the dictionaries were moved from $out/share to $out/share/skk. Also, the dictionaries won't be converted to UTF-8 unless the useUtf8 package option is enabled. UTF-8 converted dictionaries will have the .utf8 suffix appended to its filename.

  • vaultwarden lost the capability to bind to privileged ports. If you rely on this behavior, override the systemd unit to allow CAP_NET_BIND_SERVICE in your local configuration.

  • The Invoiceplane module now only accepts the structured settings option. extraConfig is now removed.

  • The ollama services replaces its sandbox toggle with options to configure a static user and group. The writablePaths option has been removed and the models directory is now always exempt from sandboxing.

  • The gns3-server service now runs under the gns3 system user instead of a dynamically created one via DynamicUser. The use of SUID wrappers is incompatible with SystemD's DynamicUser setting, and GNS3 requires calling ubridge through its SUID wrapper to function properly. This change requires to manually move the following directories:

    • from /var/lib/private/gns3 to /var/lib/gns3
    • from /var/log/private/gns3 to /var/log/gns3 and to change the ownership of these directories and their contents to gns3 (including /etc/gns3).

  • Legacy package stalwart-mail_0_6 was dropped, please note the manual upgrade process before changing the package to pkgs.stalwart-mail in services.stalwart-mail.package.

  • The nomad_1_5 package was dropped, as it has reached end-of-life upstream. Evaluating it will throw an error.

  • androidndkPkgs has been updated to androidndkPkgs_26.

  • Android NDK version 26 and SDK version 33 are now the default versions used for cross compilation to android.

  • the ankisyncd package and its services.ankisyncd have been removed, use services.anki-sync-server instead.

  • nodePackages.vscode-css-languageserver-bin, nodePackages.vscode-html-languageserver-bin, and nodePackages.vscode-json-languageserver-bin were dropped due to an unmaintained upstream. The vscode-langservers-extracted package is a maintained drop-in replacement.

  • nodePackages.prisma has been replaced by prisma.

  • fetchNextcloudApp has been rewritten to use fetchurl rather than fetchzip. This invalidates all existing hashes but you can restore the old behavior by passing it unpack = true.

  • haskell.lib.compose.justStaticExecutables now disallows references to GHC in the output by default, to alert users to closure size issues caused by #164630. See "Packaging Helpers" in the Haskell section of the Nixpkgs manual for information on working around output '...' is not allowed to refer to the following paths errors caused by this change.

  • The stalwart-mail service now runs under the stalwart-mail system user instead of a dynamically created one via DynamicUser, to avoid automatic ownership changes on its large file store each time the service was started. This change requires to manually move the state directory from /var/lib/private/stalwart-mail to /var/lib/stalwart-mail and to change the ownership of the directory and its content to stalwart-mail.

  • The stalwart-mail module now uses RocksDB as the default storage backend for stateVersion ≥ 24.11. (It was previously using SQLite for structured data and the filesystem for blobs).

  • The stargazer service has been hardened to improve security, but these changes make break certain setups, particularly around traditional CGI.

    • The stargazer.allowCgiUser option has been added, enabling Stargazer's cgi-user option to work, which was previously broken.

  • The shiori service now requires an HTTP secret value SHIORI_HTTP_SECRET_KEY to be provided via environment variable. The nixos module therefore, now provides an environmentFile option:

    # This is how a environment file can be generated:
# $ printf "SHIORI_HTTP_SECRET_KEY=%s\n" "$(openssl rand -hex 16)" > /path/to/env-file
services.shiori.environmentFile = "/path/to/env-file";

  • /share/nano is now only linked when programs.nano.enable is enabled.

  • PPD files for Utax printers got renamed (spaces replaced by underscores) in newest foomatic-db package; users of Utax printers might need to adapt their hardware.printers.ensurePrinters.*.model value.

  • The kvdo kernel module package was removed, because it was upstreamed in kernel version 6.9, where it is called dm-vdo.

  • libe57format has been updated to >= 3.0.0, which contains some backward-incompatible API changes. See the release note for more details.

  • gitlab deprecated support for runner registration tokens in GitLab 16.0, disabled their support in GitLab 17.0 and will ultimately remove it in GitLab 18.0, as outlined in the documentation. After upgrading to GitLab >= 17.0, it is possible to re-enable support for registration tokens in the UI until GitLab 18.0. Refer to the manual on using registration tokens after GitLab 17.0. GitLab administrators should migrate to the new runner registration workflow with runner authentication tokens until the release of GitLab 18.0.

  • gitlab has been updated from 16.x to 17.x and requires at least postgresql 14.9, as stated in the documentation. Check the upgrade guide in the NixOS manual on how to upgrade your PostgreSQL installation.

  • gitaly (part of gitlab) is now using the bundled git package instead of pkgs.git to maintain compatibility with GitLab.

  • nixos/gitlab no longer adds pkgs.git to environment.systemPackages by default.

  • The replay-sorcery package and module was removed as it unmaintained upstream. Consider using gpu-screen-recorder or obs-studio instead.

  • To follow RFC 0042 a few options of samba have been moved from extraConfig and configText to the new freeform option settings and renamed, e.g.:

    • services.samba.invalidUsers to services.samba.settings.global."invalid users"
    • services.samba.securityType to services.samba.settings.global."security type"
    • services.samba.shares to services.samba.settings
    • services.samba.enableWinbindd to services.samba.winbindd.enable
    • services.samba.enableNmbd to services.samba.nmbd.enable

  • zx was updated to v8, which introduces several breaking changes. See the v8 changelog for more information.

  • feishin removed support for Navidrome < v0.53.2 due to an API change; more information in the v0.10.0 release notes.

  • The dnscrypt-wrapper module was removed since the project has been effectively unmaintained since 2018; moreover the NixOS module had to rely on an abandoned version of dnscrypt-proxy v1 for the rotation of keys. To wrap a resolver with DNSCrypt you can instead use dnsdist. See options services.dnsdist.dnscrypt.*

  • The portunus package and service do not support weak password hashes anymore. If you installed Portunus on NixOS 23.11 or earlier, upgrade to NixOS 24.05 first to get support for strong password hashing. Then, follow the instructions on the upstream release notes to upgrade all existing user accounts to strong password hashes. If you need to upgrade to 24.11 without having completed the migration, consider the security implications of weak password hashes on your user accounts, and add the following to your configuration:

    services.portunus.package      = pkgs.portunus.override { libxcrypt = pkgs.libxcrypt-legacy; };
services.portunus.ldap.package = pkgs.openldap.override { libxcrypt = pkgs.libxcrypt-legacy; };

  • The default value of services.kubernetes.kubelet.hostname is now lowercased. Explicitly set kubelet.hostname to networking.fqdnOrHostName to get back the old default behavior.

  • Docker now defaults to 27.x, because version 24.x stopped receiving security updates and bug fixes after February 1, 2024.

  • postgresql was split into default and -dev outputs. To make this work without circular dependencies, the output of the pg_config system view has been removed. The pg_config binary is provided in the -dev output and still works as expected.

  • keycloak was updated to version 25, which introduces new hostname related options. See Upgrading Guide for instructions.

  • programs.vim.defaultEditor now only works if programs.vim.enable is enabled.

  • services.mautrix-meta was updated to 0.4. This release makes significant changes to the settings format. If you have custom settings you should migrate them to the new format. Unfortunately upstream provides little guidance for how to do this, but the auto-migration code may serve as a useful reference. The NixOS module should warn you if you still have any old settings configured.

  • The nodePackages.shout package has been removed because it was deprecated upstream in favor of thelounge. The shout top-level attribute was an alias to this package. The associated services.shout module has also been removed.

  • The indi-full package no longer contains non-free drivers. To get the old collection of drivers use indi-full-nonfree or create your own collection of drivers by overriding indi-with-drivers. E.g.: pkgs.indi-with-drivers.override {extraDrivers = with pkgs.indi-3rdparty; [indi-gphoto];}

  • /share/vim-plugins now only gets linked if programs.vim.enable is enabled

  • The tracy package no longer works on X11, since it's moved to Wayland support, which is the intended default behavior by Tracy maintainers. X11 users have to switch to the new package tracy-x11.

  • The services.prometheus.exporters.minio option has been removed, as it's upstream implementation was broken and unmaintained. Minio now has built-in Prometheus metrics exposure, which can be used instead.

  • The services.patroni.raft option has been removed, as Raft has been deprecated by upstream since 3.0.0

  • services.roundcube.maxAttachmentSize will multiply the value set with 1.37 to offset overhead introduced by the base64 encoding applied to attachments.

  • The services.mxisd module has been removed as both mxisd and ma1sd are not maintained any longer. Consequently the package pkgs.ma1sd has also been removed.

  • The rss-bridge service drops the support to load a configuration file from ${config.services.rss-bridge.dataDir}/config.ini.php. Consider using the services.rss-bridge.config option instead.

  • The xdg.portal.gtkUsePortal option has been removed, as it had been deprecated for over 2 years. Using the GTK_USE_PORTAL environment variable in this manner is not intended nor encouraged by the GTK developers, but can still be done manually via environment.sessionVariables.

  • Support for the legacy CUPS browsing and LDAP have been removed from services.printing. If cups or ldap are in the BrowseRemoteProtocols setting in services.printing.browsedConf, it needs to be removed.

  • The services.trust-dns module has been renamed to services.hickory-dns.

  • The option services.prometheus.exporters.pgbouncer.connectionStringFile has been removed since it leaked the connection string (and thus potentially the DB password) into the cmdline of process making it effectively world-readable.

    Use services.prometheus.exporters.pgbouncer.connectionEnvFile instead.

  • The lsh package and the services.lshd module have been removed as they had no maintainer in Nixpkgs and hadn’t seen an upstream release in over a decade. It is recommended to migrate to openssh and services.openssh.

  • ceph has been upgraded to v19. See the Ceph "squid" release notes for details and recommended upgrade procedure.

  • services.frr has been refactored to use upstream service scripts. The per-daemon configurations have been removed in favour of an integrated-vtysh-config style config. The daemon submodules now use the daemon name (e.g. ospfd) instead of the protocol name (ospf). The daemons zebra, mgmtd and staticd are always enabled if a config is present. The vtyListenAddress and vtyListenPort options have been removed; use options or extraOptions instead, respectively.

  • opencv2 and opencv3 have been removed, as they are obsolete and were not used by any other package. External users are encouraged to migrate to OpenCV 4.

  • The tvheadend package and the services.tvheadend module have been removed as nobody was willing to maintain them and they were stuck on an unmaintained version that required FFmpeg 4; please see pull request #332259 if you are interested in maintaining a newer version.

  • The antennas package and the services.antennas module have been removed as they only work with tvheadend (see above).

  • The system.build.brightboxImage image has been removed as It did not build anymore and has not seen any maintenance in over 7 years (excluding tree-wide changes).

  • The services.syncplay module now exposes all currently available command-line arguments for syncplay-server as options, as well as a useACMEHost option for easy TLS setup. The systemd service now uses DynamicUser/StateDirectory and the user and group options have been deprecated.

  • The openlens package got removed, suggested replacement lens-desktop

  • The services.dnsmasq.extraConfig option has been removed, as it had been deprecated for over 2 years. This option has been replaced by services.dnsmasq.settings.

  • The NixOS installation media no longer support the ReiserFS or JFS file systems by default.

  • Minimal installer ISOs are no longer built on the small channel. Please obtain installer images from the full release channels.

  • The default FFmpeg version is now 7, and FFmpeg 5 has been removed. Please prefer using the package variants without a version suffix, or pin FFmpeg 6 or 4 if necessary for compatibility. Note that we keep old versions around only as required to support packages in the tree, and FFmpeg 4 especially should be avoided in favour of newer versions as it may be removed soon.

  • openssl now defaults to the latest version line 3.3.x, instead of 3.0.x before. While there should be no major code incompatibilities, newer OpenSSL versions typically strengthen the default security level. This means that you may have to explicitly allow weak ciphers, hashes and key lengths if necessary. See: OpenSSL security level documentation.

  • The isync package has been updated to version 1.5.0, which introduces some breaking changes. See the compatibility concerns for more details.

  • Legacy package globalprotect-openconnect 1.x and related module globalprotect-vpn were dropped. Two new packages gpauth and gpclient from the 2.x version of the GlobalProtect-openconnect project are added in its place. The GUI components related to the project are non-free and not packaged.

  • Compatible string matching for hardware.deviceTree.overlays has been changed to a more correct behavior. See below for details.

  • The rustic package was upgrade to 0.9.0, which contains breaking changes to the config file format.

  • pkgs.formats.ini and pkgs.formats.iniWithGlobalSection with listsAsDuplicateKeys or listToValue no longer merge non-list values into lists by default. Backwards-compatible behavior can be enabled with atomsCoercedToLists.

  • python3Packages.nose has been removed, as it has been deprecated and unmaintained for almost a decade and does not work on Python 3.12. Please switch to pytest or another test runner/framework.

Other Notable Changes

  • The zerocallusedregs hardening flag is enabled by default on compilers that support it.

  • The stackclashprotection hardening flag has been added, though disabled by default.

  • The pacret hardening flag has been added, though disabled by default.

  • cargoSha256 in rustPlatform.buildRustPackage has been deprecated in favor of cargoHash which supports SRI hashes. See buildRustPackage: Compiling Rust applications with Cargo for more information.

  • The vendorHash of Go packages built with buildGoModule can now be overridden with overrideAttrs. goModules, modRoot, vendorHash, deleteVendor, and proxyVendor are now passed as derivation attributes. goModules and vendorHash are no longer placed under passthru.

  • buildFlags/buildFlagsArray on buildGoModule have been deprecated. 24.11 is the last release where buildGoModule accepts these flags (while throwing a warning). Use the ldflags and/or tags attributes or the environment instead.

  • buildGoPackage has been deprecated. 24.11 is the last release with buildGoPackage available.

  • hareHook has been added as the language framework for Hare. From now on, it, not the hare package, should be added to nativeBuildInputs when building Hare programs.

  • lib.options.mkPackageOptionMD is now obsolete; use the identical lib.options.mkPackageOption instead.

  • lib.misc.mapAttrsFlatten is now formally deprecated and will be removed in future releases; use the identical lib.attrsets.mapAttrsToList instead.

  • Tailscale's authKeyFile can now have its corresponding parameters set through config.services.tailscale.authKeyParameters, allowing for non-ephemeral unsupervised deployment and more. See Registering new nodes using OAuth credentials for the supported options.

  • nixosTests now provide a working IPv6 setup for VLAN 1 by default.

  • Kanidm can now be provisioned using the new [services.kanidm.provision] option, but requires using a patched version available via pkgs.kanidm.withSecretProvisioning.

  • Kanidm previously had an incorrect systemd service type, causing dependent units with an after and requires directive to start before kanidm* finished startup. The module has now been updated in line with upstream recommendations.

  • The kubelet configuration file can now be amended with arbitrary additional content using the services.kubernetes.kubelet.extraConfig option.

  • The services.seafile module was updated to major version 11.

    • As part of this upgrade, the database backend will be migrated to MySQL. This process should be automatic, but in case of a botched migration, old sqlite files are not removed and can be used to manually migrate the database.
    • Additionally, the updated CSRF protection may prevent some users from logging in. Specific origin addresses can be whitelisted using the services.seafile.seahubExtraConf option (e.g. services.seafile.seahubExtraConf = ''CSRF_TRUSTED_ORIGINS = ["https://example.com"]'';). Note that first solution of the official FAQ answer is not allowed by the services.nginx module's config-checker.

  • The latest available version of Nextcloud is v30 (available as pkgs.nextcloud30). The installation logic is as follows:

  • To facilitate dependency injection, the imgui package now builds a static archive using vcpkg' CMake rules. The derivation now installs "impl" headers selectively instead of by a wildcard. Use imgui.src if you just want to access the unpacked sources.

  • The new boot.loader.systemd-boot.windows option makes setting up dual-booting with Windows on a different drive easier

  • Linux 4.19 has been removed because it will reach its end of life within the lifespan of 24.11

  • Unprivileged access to the kernel syslog via dmesg is now restricted by default. Users wanting to keep an unrestricted access to it can set boot.kernel.sysctl."kernel.dmesg_restrict" = false.

  • The i18n.inputMethod module introduces two new properties: enable and type, for declaring whether to enable an alternative input method and defining which input method respectfully. The options available in type are the same as the existing enabled option. enabled is now deprecated, and will be removed in a future release.

  • security.pam.u2f now follows RFC42. All module options are now settable through the freeform .settings.

  • Mikutter was removed because the package was broken and had no maintainers.

  • The new option services.getty.autologinOnce was added to limit the automatic login to once per boot and on the first tty only. When using full disk encryption, this option allows to unlock the system without retyping the passphrase while keeping the other ttys protected.

  • Gollum was upgraded to major version 6. Read their migration notes.

  • The hooks yarnConfigHook and yarnBuildHook were added. These should replace yarn2nix.mkYarnPackage and other yarn2nix related tools. The motivation to get rid of yarn2nix tools is the fact that they are too complex and hard to maintain, and they rely upon too much Nix evaluation which is problematic if import-from-derivation is not allowed (see more details at #296856. The transition from mkYarnPackage to yarn{Config,Build}Hook is tracked at #324246.

  • services.timesyncd.servers now defaults to null, allowing systemd-timesyncd to use NTP servers advertised by DHCP.

  • services.timesyncd.fallbackServers was added and defaults to networking.timeServers.

  • Cinnamon has been updated to 6.2, please check upstream announcement for more details. Following Mint 22 defaults, the Cinnamon module no longer ships geary and hexchat by default.

  • zfs.latestCompatibleLinuxPackages is deprecated and is now pointing at the default kernel. If using the stable LTS kernel (default linuxPackages is not possible then you must explicitly pin a specific kernel release. For example, boot.kernelPackages = pkgs.linuxPackages_6_6. Please be aware that non-LTS kernels are likely to go EOL before ZFS supports the latest supported non-LTS release, requiring manual intervention.

  • The shadowstack hardening flag has been added, though disabled by default.

  • xxd is now provided by the tinyxxd package, rather than vim.xxd, to reduce closure size and vulnerability impact. Since it has the same options and semantics as Vim's xxd utility, there is no user impact. Vim's xxd remains available as the vim.xxd package.

  • prometheus-openldap-exporter was removed since it was unmaintained upstream and had no nixpkgs maintainers.

  • restic module now has an option for inhibiting system sleep while backups are running, defaulting to off (not inhibiting sleep), available as services.restic.backups.<name>.inhibitsSleep.

  • The arguments from now get shell-escaped.

  • Mattermost has been updated from 9.5 to 9.11 ESR. See the changelog for more details.

  • cargo-tauri.hook was introduced to help users build Tauri projects. It is meant to be used alongside rustPlatform.buildRustPackage and Node hooks such as npmConfigHook, pnpm.configHook, and the new yarnConfig

  • power.ups now powers off UPSs during a power outage event. This saves UPS battery and ensures that host(s) get back up again when power comes back, even in the scenario when the UPS would have had enough capacity to keep power on during the whole power outage. If you like the old behaviour of keeping the UPSs on (and emptying the battery) after the host(s) have shut down, and risk not getting a power cycle event to get the host(s) back up, set power.ups.upsmon.settings.POWERDOWNFLAG = null;.

  • nixos-firewall-tool now supports nftables in addition to iptables and is installed by default when NixOS firewall is enabled.

  • Support for runner registration tokens has been deprecated in gitlab-runner 15.6 and is expected to be removed in gitlab-runner 18.0. Configuration of existing runners should be changed to using runner authentication tokens by configuring {option}services.gitlab-runner.services.<name>.authenticationTokenConfigFile instead of the former {option}services.gitlab-runner.services.<name>.registrationConfigFile option.

  • iproute2 now has libbpf support.

  • nix.channel.enable = false no longer implies nix.settings.nix-path = []. Since Nix 2.13, a nix-path set in nix.conf cannot be overridden by the NIX_PATH configuration variable.

  • ZFS now imports its pools in postResumeCommands rather than postDeviceCommands. If you had postDeviceCommands scripts that depended on ZFS pools being imported, those now need to be in postResumeCommands.

  • services.automatic-timezoned.enable = true will now set time.timeZone = null. This is to avoid silently shadowing a user's explicitly defined timezone without recognition on the user's part.

  • services.localtimed.enable = true will now set time.timeZone = null. This is to avoid silently shadowing a user's explicitly defined timezone without recognition on the user's part.

  • qgis and qgis-ltr are now built without grass by default. grass support can be enabled with qgis.override { withGrass = true; }.

Detailed migration information

sound options removal

The sound options have been largely removed, as they are unnecessary for most modern setups, and cause issues when enabled.

If you set sound.enable in your configuration:

  • If you are using Pulseaudio or PipeWire, simply remove that option
  • If you are not using an external sound server, and want volumes to be persisted across shutdowns, set hardware.alsa.enablePersistence = true instead

If you set sound.enableOSSEmulation in your configuration:

  • Make sure it is still necessary, as very few applications actually use OSS
  • If necessary, set boot.kernelModules = [ "snd_pcm_oss" ]

If you set sound.extraConfig in your configuration:

  • If you are using another sound server, like Pulseaudio, JACK or PipeWire, migrate your configuration to that
  • If you are not using an external sound server, set environment.etc."asound.conf".text = yourExtraConfig instead

If you set sound.mediaKeys in your configuration:

  • Preferably switch to handling media keys in your desktop environment/compositor
  • If you want to maintain the exact behavior of the option, use the following snippet
services.actkbd = let
  volumeStep = "1%";
in {
  enable = true;
  bindings = [
    # "Mute" media key
    { keys = [ 113 ]; events = [ "key" ];       command = "${alsa-utils}/bin/amixer -q set Master toggle"; }

    # "Lower Volume" media key
    { keys = [ 114 ]; events = [ "key" "rep" ]; command = "${alsa-utils}/bin/amixer -q set Master ${volumeStep}- unmute"; }

    # "Raise Volume" media key
    { keys = [ 115 ]; events = [ "key" "rep" ]; command = "${alsa-utils}/bin/amixer -q set Master ${volumeStep}+ unmute"; }

    # "Mic Mute" media key
    { keys = [ 190 ]; events = [ "key" ];       command = "${alsa-utils}/bin/amixer -q set Capture toggle"; }
  ];
};

hardware.deviceTree.overlays compatible string matching

The original compatible string implementation in older NixOS versions relied on substring matching, which is incorrect for overlays with multiple compatible strings and other cases.

The new behavior is consistent with what other tools already do - the overlay is considered applicable if, and only if, any of the compatible strings in the overlay match any of the compatible strings in the DT.

To provide some examples:

Overlay compatible DT compatible Pre-24.11 behavior Correct behavior Notes
"foo" "foo", "bar" match match Most common use case does not change
"foo" "foobar" match no match Substrings should not be matched
"foo bar" "foo", "bar" match no match Separators should not be matched to spaces
"foo", "bar" "baz", "bar" no match match One compatible string matching is enough

Note that this also allows writing overlays that explicitly apply to multiple boards.
