3.7 KiB
Release 22.11 (“Raccoon”, 2022.11/??)
Support is planned until the end of June 2023, handing over to 23.05.
Highlights
In addition to numerous new and upgraded packages, this release has the following highlights:
-
During cross-compilation, tests are now executed if the test suite can be executed by the build platform. This is the case when doing “native” cross-compilation where the build and host platforms are largely the same, but the nixpkgs' cross compilation infrastructure is used, e.g.
pkgsStatic
andpkgsLLVM
. Another possibility is that the build platform is a superset of the host platform, e.g. when cross-compiling fromx86_64-unknown-linux
toi686-unknown-linux
. The predicate gating test suite execution is the newly addedcanExecute
predicate: You can e.g. check ifstdenv.buildPlatform
can execute binaries built forstdenv.hostPlatform
(i.e. produced bystdenv.cc
) by evaluatingstdenv.buildPlatform.canExecute stdenv.hostPlatform
. -
PHP now defaults to PHP 8.1, updated from 8.0.
-
hardware.nvidia
has a new optionopen
that can be used to opt in the opensource version of NVIDIA kernel driver. Note that the driver's support for GeForce and Workstation GPUs is still alpha quality, see NVIDIA Releases Open-Source GPU Kernel Modules for the official announcement.
New Services
- appvm, Nix based app VMs. Available as virtualisation.appvm.
Backward Incompatibilities
-
The
isCompatible
predicate checking CPU compatibility is no longer exposed by the platform sets generated usinglib.systems.elaborate
. In most cases you will want to use the newcanExecute
predicate instead which also considers the kernel / syscall interface. It is briefly described in the release's highlights section.lib.systems.parse.isCompatible
still exists, but has changed semantically: Architectures with differing endianness modes are no longer considered compatible. -
The
isPowerPC
predicate, found onplatform
attrsets (hostPlatform
,buildPlatform
,targetPlatform
, etc) has been removed in order to reduce confusion. The predicate was was defined such that it matches only the 32-bit big-endian members of the POWER/PowerPC family, despite having a name which would imply a broader set of systems. If you were using this predicate, you can replacefoo.isPowerPC
with(with foo; isPower && is32bit && isBigEndian)
.
Other Notable Changes
- A new module was added for the Saleae Logic device family, providing the options
hardware.saleae-logic.enable
andhardware.saleae-logic.package
. - Matrix Synapse now requires entries in the
state_group_edges
table to be unique, in order to prevent accidentally introducing duplicate information (for example, because a database backup was restored multiple times). If your Synapse database already has duplicate rows in this table, this could fail with an error and require manual remediation.
