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.
-
services.postgresql.ensurePermissions
has been deprecated in favor ofservices.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 wayGRANT 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
orpostStart
. Refer to the PR #266270 for more details. -
network-online.target
has been fixed to no longer time out for systems withnetworking.useDHCP = true
andnetworking.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 ofpython3.pkgs.pysequoia
. The latter package is based on upstream's dedicated repository for sequoia's Python bindings, where the Python bindings from gitlab:sequoia-pgp/sequoia were removed long ago. -
writeTextFile
requiresexecutable
to be boolean now, values likenull
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 itsstreaming
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 supportpasswordFile
like options, WPA3-SAE, and management of multiple interfaces. This breaks compatibility with older configurations.hostapd
is now started with additional systemd sandbox/hardening options for better security.services.hostapd.interface
was replaced with a per-radio and per-bss configuration scheme using services.hostapd.radios.services.hostapd.wpa
has been replaced by services.hostapd.radios.<name>.networks.<name>.authentication.wpaPassword and services.hostapd.radios.<name>.networks.<name>.authentication.saePasswords which configure WPA2-PSK and WP3-SAE respectively.- The default authentication has been changed to WPA3-SAE. Options for other (legacy) schemes are still available.
-
python3.pkgs.fetchPypi
andpython3Packages.fetchPypi
have been deprecated in favor of top-levelfetchPypi
. -
xdg-desktop-portal has been updated to 1.18, which reworked how portal implementations are selected. If you roll your own desktop environment, you should either set
xdg.portal.config
orxdg.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 runG_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 containpassword-store.el
. Users should getpassword-store.el
from Emacs lisp package setemacs.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 installmu4e
files by default now. Users should getmu4e
from Emacs lisp package setemacs.pkgs.mu4e
. -
mariadb
now defaults tomariadb_1011
instead ofmariadb_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 fromglibc
'sbin
output to its own dedicated output, reducing closure size for many dependents. Dependents using thegetent
alias should not be affected; others should move from usingglibc.bin
orgetBin glibc
togetent
(which also improves compatibility with non-glibc platforms). -
maintainers/scripts/update-luarocks-packages
is now a proper packageluarocks-packages-updater
that can be run to maintain out-of-tree luarocks packages. -
The
users.users.<name>.passwordFile
has been renamed tousers.users.<name>.hashedPasswordFile
to avoid possible confusions. The option is in fact the file-based version ofhashedPassword
, notpassword
, and expects a file containing the {manpage}crypt(3)
hash of the user password. -
chromiumBeta
andchromiumDev
have been removed due to the lack of maintenance in nixpkgs. Consider usingchromium
instead. -
google-chrome-beta
andgoogle-chrome-dev
have been removed due to the lack of maintenance in nixpkgs. Consider usinggoogle-chrome
instead. -
The
services.ananicy.extraRules
option now has the type oflistOf attrs
instead ofstring
. -
buildVimPluginFrom2Nix
has been renamed tobuildVimPlugin
, which now now skipsconfigurePhase
andbuildPhase
. -
JACK tools (
jack_*
exceptjack_control
) have moved from thejack2
package tojack-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 modifiesmatrix-synapse-unwrapped
instead. More on that below. - The
enableSystemd
&enableRedis
arguments have been removed andmatrix-synapse
has been renamed tomatrix-synapse-unwrapped
. Also, several optional dependencies (such aspsycopg2
orauthlib
) have been removed. - These optional dependencies are automatically added via a wrapper
(
pkgs.matrix-synapse.override { extras = ["redis"]; }
forhiredis
&txredisapi
for instance) if the relevant config section is declared inservices.matrix-synapse.settings
. For instance, ifservices.matrix-synapse.settings.redis.enabled
is set totrue
,"redis"
will be automatically added to theextras
list ofpkgs.matrix-synapse
. - A list of all extras (and the extras enabled by default) can be found at
the option's reference for
services.matrix-synapse.extras
. - In some cases (e.g. for running synapse workers) it was necessary to re-use
the
PYTHONPATH
ofmatrix-synapse.service
's environment to have all plugins available. This isn't necessary anymore, insteadconfig.services.matrix-synapse.package
can be used as it points to the wrapper with properly configuredextras
and also all plugins defined viaservices.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.
- The option
-
netbox
was updated to v3.6.services.netbox.package
still defaults to v3.5 ifstateVersion
is earlier than 23.11. Refer to upstream's breaking changes for v3.6.0 and upgrade NetBox by changingservices.netbox.package
. Database migrations will be run automatically. -
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 togitlab
>=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 torocmPackages.llvm
. -
hip
,rocm-opencl-runtime
,rocm-opencl-icd
, androcclr
have been combined intorocmPackages.clr

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 ofphpOptions
are still defaults, these can be overridden as shown here.To override all of the options (including including
upload_max_filesize
,post_max_size
andmemory_limit
which all point toservices.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 likellvm-installable-svm
andnative-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 notablecontrolInterface
needs migration towardsunbound.host
and requires either thetcp://
orunix://
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 asvarnish60
. -
util-linux
is now supported on Darwin and is no longer an alias tounixtools
. Use theunixtools.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 thekbd
package has been moved into its own package output and should now be referenced explicitly askbd.vlock
or replaced with an alternative such as the standalonevlock
package orphyslock
. -
fileSystems.<name>.autoFormat
now usessystemd-makefs
, which does not accept formatting options. Therefore,fileSystems.<name>.formatOptions
has been removed. -
fileSystems.<name>.autoResize
usessystemd-growfs
to resize the file system online in Stage 2 now. This means thatf2fs
andext2
can no longer be auto resized, whilexfs
andbtrfs
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 insidesystemd-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 theNIXOS_SWITCH_USE_DIRTY_ENV
environment variable before runningnixos-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 withstateVersion = "23.05";
or older follow the migration steps from https://git.asonix.dog/asonix/pict-rs#user-content-0-3-to-0-4-migration-guide and setservices.pict-rs.package = pkgs.pict-rs;
. -
The following packages in
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"${lib.getExe pkgs.haskellPackages.nixfmt}"
. The binaries also won’t be in scope if you rely on them being installed e.g. viaghcWithPackages
.environment.packages
picks thebin
output automatically, so for normal installation no intervention is required. Also, toplevel attributes likepkgs.nixfmt
are not impacted negatively by this change. -
spamassassin
no longer supports theHashcash
module. The module needs to be removed from theloadplugin
list if it was copied over from the defaultinitPreConf
option. -
nano
was removed fromenvironment.defaultPackages
. To not leave systems without a editor, nowprograms.nano.enable
is enabled by default. -
programs.nano.nanorc
andprograms.nano.syntaxHighlight
no longer have an effect unlessprograms.nano.enable
is set to true which is the default. -
services.outline.sequelizeArguments
has been removed, asoutline
no longer executes database migrations via thesequelize
cli. -
The binary of the package
cloud-sql-proxy
has changed fromcloud_sql_proxy
tocloud-sql-proxy
. -
The module
services.apache-kafka
was largely rewritten and has certain breaking changes. To be precise, this means that the following things have changed:- Most settings have been migrated to services.apache-kafka.settings.
- By virtue of being less opinionated, it is now possible to use the module
to run Apache Kafka in KRaft mode instead of Zookeeper mode.
- A few options have been added to assist in this mode.
-
Garage has been upgraded to v0.9.x.
services.garage.package
needs to be explicitly set now, so version upgrades can be done in a controlled fashion. For this, we exposegarage_x_y
attributes which can be set here. -
voms
andxrootd
now moves the$out/etc
content to the$etc
output instead of$out/etc.orig
, when input argumentexternalEtc
is notnull
. -
The
woodpecker-*
CI packages have been updated to v1.0.0. This release is wildly incompatible with the v0.15.x versions that were previously packaged. Refer to upstream's documentation to learn how to update your CI configurations. -
Meilisearch was updated from v1.3.1 to v1.5.0. The update has breaking changes about backslashes and filtering. Refer to the release announcement for more details.
-
The Caddy module gained a new option named
services.caddy.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 settinggrace_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 bynixos-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 usestateVersion
correctly or setboot.swraid.enable
manually. On systems with an updatedstateVersion
we now also emit warnings ifmdadm.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 fromleveldb
topebble
butleveldb
can be forced with the --db.engine=leveldb flag. Thecheckpoint-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 thelibresprite
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, thepharo-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 attributeemacs29-pgtk
. -
Emacs macport version 29 was introduced.
-
The option
services.networking.networkmanager.enableFccUnlock
was removed in favor ofnetworking.networkmanager.fccUnlockScripts
, which allows specifying unlock scripts explicitly. The previous option enabled all unlock scripts bundled with ModemManager, which is risky, and didn't allow using vendor-provided unlock scripts at all. -
The
html-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 fromlink
tocode
. -
The
hail
module was removed, ashail
was unmaintained since 2017. -
Package
noto-fonts-emoji
was renamed tonoto-fonts-color-emoji
. Refer to PR #221181 for more details. -
Package
cloud-sql-proxy
was renamed togoogle-cloud-sql-proxy
as it cannot be used with other cloud providers. -
Package
pash
was removed due to being archived upstream. Usepowershell
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 thatreleaseCookiePath
was set to. -
security.sudo.extraRules
includesroot
's default rule now, with ordering priority 400. This is functionally identical for users not specifying rule order, or relying onmkBefore
andmkAfter
, but may impact users callingmkOrder n
with n ≤ 400. -
X keyboard extension (XKB) options have been reorganized into a single attribute set,
services.xserver.xkb
. Specifically,services.xserver.layout
isservices.xserver.xkb.layout
now,services.xserver.extraLayouts
isservices.xserver.xkb.extraLayouts
now,services.xserver.xkbModel
isservices.xserver.xkb.model
now,services.xserver.xkbOptions
isservices.xserver.xkb.options
now ,services.xserver.xkbVariant
isservices.xserver.xkb.variant
now, andservices.xserver.xkbDir
isservices.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 bybiome
. -
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 ofservices.mtr-exporter.jobs
which allows specifying multiple targets. -
blender-with-packages
has been deprecated in favor ofblender.withPackages
, for exampleblender.withPackages (ps: [ps.bpycv])
. It behaves similarly topython3.withPackages
. -
Setting
nixpkgs.config
options while providing an externalpkgs
instance will now raise an error instead of silently ignoring the options. NixOS modules no longer setnixpkgs.config
to accommodate this. This specifically affectsservices.locate
,services.xserver.displayManager.lightdm.greeters.tiny
andprograms.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 correspondingprivacyidea-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 calleddagger
and packaging it from source violates their trademark policy. -
win-virtio
package was renamed tovirtio-win
to be consistent with the upstream package name. -
ps3netsrv
has been replaced with the webman-mod fork, the executable has been renamed fromps3netsrv++
tops3netsrv
and cli parameters have changed. -
ssm-agent
package and module were renamed toamazon-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, plainJunicode.ttf
no longer exists. In addition, TrueType font files are now placed infont/truetype
instead offont/junicode-ttf
; this change does not affect use viafonts.packages
option. -
The
prayer
package as well asservices.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 withrtcfile
and automatically adjusts it withrtcautotrim
when it exceeds the maximum error specified inservices.chrony.autotrimThreshold
(defaults to 30 seconds). If you enabledrtcsync
inextraConfig
, you should remove RTC related options fromextraConfig
. If you do not want chrony configured to keep the RTC in check, you can setservices.chrony.enableRTCTrimming = false;
. -
trilium-desktop
andtrilium-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 bylinuxPackages_testing
.- Please consider changing your NixOS configuration's
boot.kernelPackages
tolinuxPackages_testing
until a stable kernel with bcachefs support is released.
- Please consider changing your NixOS configuration's
-
PostgreSQL now defaults to major version 15.
-
All ROCm packages have been updated to v5.7.0.
- ROCm package attribute sets are
versioned:
rocmPackages
->rocmPackages_5
.
- ROCm package attribute sets are
versioned:
-
systemd has been updated from v253 to v254, refer to the release notes for more details.
boot.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 thenixos-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 = ${CUSTOMSHELL}
, the assertion will require them to also setprograms.${CUSTOMSHELL}.enable = true
. This is generally safe behavior, but for anyone needing to opt out from the checkusers.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.

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"; }; }

The
fonts.fonts
andfonts.enableDefaultFonts
options have been renamed tofonts.packages
andfonts.enableDefaultPackages
respectively. -
services.hedgedoc

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:- If
services.nextcloud.package
is specified explicitly, this package will be installed (recommended) - If
system.stateVersion
is >=23.11,pkgs.nextcloud27
will be installed by default. - If
system.stateVersion
is >=23.05,pkgs.nextcloud26
will be installed by default. - Please note that an upgrade from v25 (or older) to v27 is not possible
directly. Please upgrade to
nextcloud26
(or earlier) first. Nextcloud prohibits skipping major versions while upgrading. You may upgrade by declaringservices.nextcloud.package = pkgs.nextcloud26;

now. It will no longer take precedence over apinentry-program
set in~/.gnupg/gpg-agent.conf
. -
python3.pkgs.flitBuildHook
has been removed. Useflit-core
andformat = "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 viamaxConcurrentRenewals
. Setting the value to 0 disables the limits altogether. -
services.borgmatic.settings.location
andservices.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 optionsdaemonConfig
andextraSettings
have respectively been replaced bydaemonSettings
andjails.DEFAULT.settings
. Those use attribute sets. -
The
services.mbpfan
module has the optionaggressive
enabled by default now. This is for better heat moderation. To get the upstream defaults you may disable this. -
Apptainer/Singularity defaults to using
"$out/var/lib"
for theLOCALSTATEDIR
configuration option instead of the top-level"/var/lib"
now. This change impacts theSESSIONDIR
(container-run-time mount point) configuration, which is set to$LOCALSTATEDIR/<apptainer or singularity>/mnt/session
. This detaches the packages from the top-level directory, rendering the NixOS module optional.The default behavior of the NixOS module
programs.singularity
stays unchanged. We add a new optionprograms.singularity.enableExternalSysConfDir
(default totrue
) to specify whether to set the top-level"/var/lib"
asLOCALSTATEDIR
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)
andlibev
-based connection handling method. Refer to the sslh docs for a comparison. -
Suricata was upgraded from v6.0 to v7.0 and no longer considers HTTP/2 support as experimental. Refer to upstream release notes for more details.
-
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 settingservices.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 defaultunpackPhase
is deprecated as it requiresunpackPhase
to always produce a directory named "source". UsesourceRoot = src.name
,sourceRoot = "${src.name}/subdir";
, orsetSourceRoot = "sourceRoot=$(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 settingvirtualisation.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 changinglib
tolibexec

There is a new NixOS option when writing NixOS tests
testing.initrdBackdoor
, that enablesbackdoor.service
in initrd. Requiresboot.initrd.systemd.enable
to be enabled. Boot will pause in Stage 1 atinitrd.target
