- **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](https://dortania.github.io/OpenCore-Legacy-Patcher/) for old hardware) or installing NixOS.
If neither of those options are viable and you require new versions of software, [MacPorts](https://www.macports.org/) supports back to Mac OS X Snow Leopard 10.6.
- [AMDVLK](https://github.com/GPUOpen-Drivers/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.
-`authelia` has been upgraded to version 4.38. This version brings several features and improvements which are detailed in the [release blog post](https://www.authelia.com/blog/4.38-release-notes/).
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`).
- The [Xen Project Hypervisor](https://xenproject.org) is once again available as a virtualisation option under [`virtualisation.xen`](#opt-virtualisation.xen.enable).
- This release includes Xen [4.19.0](https://wiki.xenproject.org/wiki/Xen_Project_4.19_Release_Notes) and support for booting the hypervisor on EFI systems.
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 OCaml-based Xen Store can now be configured using [`virtualisation.xen.store.settings`](#opt-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`](#opt-systemd.enableStrictShellChecks) has been added. When enabled, all systemd scripts generated by NixOS will
be checked with [shellcheck](https://www.shellcheck.net) 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.

- The `sound` options have been removed or renamed, as they had a lot of unintended side effects. See [below](#sec-release-24.11-migration-sound) 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`](https://nixos.org/manual/nixpkgs/unstable/#sec-pkg-override) provided by `callPackage` shadows such a locally-defined `override` attribute.
-`transmission` package has been aliased with a `trace` warning to `transmission_3`. Since [Transmission 4 has been released last year](https://github.com/transmission/transmission/releases/tag/4.0.0), 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](https://github.com/transmission/transmission/issues/5153), [#6796](https://github.com/transmission/transmission/issues/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](https://www.mongodb.com/docs/manual/release-notes/6.0-compatibility/) and [7.0](https://www.mongodb.com/docs/manual/release-notes/7.0-compatibility/).
-`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.
-`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).
-`knot-dns` has been updated to version 3.4.x. Check the [migration guide](https://www.knot-dns.cz/docs/latest/html/migration.html#upgrade-3-3-x-to-3-4-x) 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`).
-`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](https://dev.mysql.com/doc/refman/8.4/en/native-pluggable-authentication.html). 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](https://www.percona.com/blog/no-mysql-9-x-innovation-releases-from-percona/). 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.
-`buildbot` was updated to 4.0, the AngularJS frontend has been replaced by a React frontend, see the [upstream release notes](https://docs.buildbot.net/current/manual/upgrading/4.0-upgrade.html).
-`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](https://github.com/juanfont/headscale/releases/tag/v0.23.0) 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`).
- 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](security.sudo.extraRules) or [polkit](security.polkit.extraConfig) 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.
- 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 method to safely handle secrets in the `networking.wireless` module has been changed to benefit from a [new feature](https://w1.fi/cgit/hostap/commit/?id=e680a51e94a33591f61edb210926bcb71217a21a) 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.
-`frigate` was updated past 0.14.0. This release includes various breaking changes, so please go read the [release notes](https://github.com/blakeblackshear/frigate/releases/tag/v0.14.0).
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.
-`forgejo` and `forgejo-lts` no longer support the opt-in feature [PAM (Pluggable Authentication Module)](https://forgejo.org/docs/latest/user/authentication/#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`](#opt-services.pgbouncer.settings) according to the NixOS RFC 0042.
- The `nomad_1_5` package was dropped, as [it has reached end-of-life upstream](https://support.hashicorp.com/hc/en-us/articles/360021185113-Support-Period-and-End-of-Life-EOL-Policy). Evaluating it will throw an error.
- the `ankisyncd` package and its `services.ankisyncd` have been removed, use [`services.anki-sync-server`](#opt-services.anki-sync-server.enable) instead.
- 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:
- 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.
-`libe57format` has been updated to `>= 3.0.0`, which contains some backward-incompatible API changes. See the [release note](https://github.com/asmaloney/libE57Format/releases/tag/v3.0.0) for more details.
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](https://docs.gitlab.com/17.0/ee/ci/runners/new_creation_workflow.html#using-registration-tokens-after-gitlab-170).
GitLab administrators should migrate to the [new runner registration workflow](https://docs.gitlab.com/17.0/ee/ci/runners/new_creation_workflow.html#using-registration-tokens-after-gitlab-170)
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](https://docs.gitlab.com/17.1/ee/install/requirements.html#postgresql-requirements). Check the [upgrade guide](#module-services-postgres-upgrading) in the NixOS manual on how to upgrade your PostgreSQL installation.
- To follow [RFC 0042](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md) a few options of `samba` have been moved from `extraConfig` and `configText` to the new freeform option `settings` and renamed, e.g.:
-`feishin` removed support for Navidrome `< v0.53.2` due to an API change; more information in the [v0.10.0 release notes](https://github.com/jeffvli/feishin/releases/tag/v0.10.0).
- 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](https://github.com/majewsky/portunus/releases/tag/v2.0.0) 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:
- Docker now defaults to 27.x, because version 24.x stopped receiving security updates and bug fixes after [February 1, 2024](https://github.com/moby/moby/pull/46772#discussion_r1686464084).
-`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.
-`services.mautrix-meta` was updated to [0.4](https://github.com/mautrix/meta/releases/tag/v0.4.0). 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](https://github.com/mautrix/meta/blob/f5440b05aac125b4c95b1af85635a717cbc6dd0e/cmd/mautrix-meta/legacymigrate.go#L23) may serve as a useful reference. The NixOS module should warn you if you still have any old settings configured.
- 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](https://min.io/docs/minio/linux/operations/monitoring/collect-minio-metrics-using-prometheus.html), which can be used instead.
- The `services.patroni.raft` option has been removed, as Raft has been [deprecated by upstream since 3.0.0](https://github.com/patroni/patroni/blob/master/docs/releases.rst#version-300)
-`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](https://github.com/kamax-matrix/mxisd) and [ma1sd](https://github.com/ma1uta/ma1sd) are not maintained any longer.
Consequently the package `pkgs.ma1sd` has also been removed.
- 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 `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](https://docs.ceph.com/en/latest/releases/squid/#v19-2-0-squid) for details and recommended upgrade procedure.
- 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 `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`.
-`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](https://docs.openssl.org/3.3/man3/SSL_CTX_set_security_level/).
- The `isync` package has been updated to version `1.5.0`, which introduces some breaking changes. See the [compatibility concerns](https://sourceforge.net/projects/isync/files/isync/1.5.0/) for more details.
- Compatible string matching for `hardware.deviceTree.overlays` has been changed to a more correct behavior. See [below](#sec-release-24.11-migration-dto-compatible) for details.
- The `rustic` package was upgrade to `0.9.0`, which contains [breaking changes to the config file format](https://github.com/rustic-rs/rustic/releases/tag/v0.9.0).
- [`lib.options.mkPackageOptionMD`](https://nixos.org/manual/nixpkgs/unstable#function-library-lib.options.mkPackageOptionMD) is now obsolete; use the identical [`lib.options.mkPackageOption`](https://nixos.org/manual/nixpkgs/unstable#function-library-lib.options.mkPackageOption) instead.
-`lib.misc.mapAttrsFlatten` is now formally deprecated and will be removed in future releases; use the identical [`lib.attrsets.mapAttrsToList`](https://nixos.org/manual/nixpkgs/unstable#function-library-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](https://tailscale.com/kb/1215/oauth-clients#registering-new-nodes-using-oauth-credentials) for the supported options.
- 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.
Note that first solution of the [official FAQ answer](https://cloud.seatable.io/dtable/external-links/7b976c85f504491cbe8e/?tid=0000&vid=0000&row-id=BQhH-2HSQs68Nq2EW91DBA)
is not allowed by the `services.nginx` module's config-checker.
- If [`system.stateVersion`](#opt-system.stateVersion) is >=24.11, `pkgs.nextcloud30` will be installed by default.
- Please note that an upgrade from v28 (or older) to v30 directly is not possible. Please upgrade to `nextcloud29` (or earlier) first. Nextcloud prohibits skipping major versions while upgrading. You can upgrade by declaring [`services.nextcloud.package = pkgs.nextcloud29;`](options.html#opt-services.nextcloud.package).
- 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.
- 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](https://github.com/NixOS/nixpkgs/issues/296856). The transition from `mkYarnPackage` to `yarn{Config,Build}Hook` is tracked at [#324246](https://github.com/NixOS/nixpkgs/issues/324246).
-`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.
-`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.
-`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`](#opt-services.restic.backups._name_.inhibitsSleep).
-`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;`.
- 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`.
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
