This reverts commit6cec87c32d. Now that https://github.com/NixOS/nixpkgs/pull/326142 has landed, there's no reason to keep ourselves pinned to Python 3.11 anymore. As a happy side effect, this also fixes a bug with6cec87c32dwhich broke our ability to use kicad addons: $ nix build --impure --expr 'with import ./. {}; pkgs.kicad.override { addons = with pkgs.kicadAddons; [kikit kikit-library]; }' -L ... error: … while calling the 'derivationStrict' builtin at <nix/derivation-internal.nix>:34:12: 33| 34| strict = derivationStrict drvAttrs; | ^ 35| … while evaluating derivation 'kicad-8.0.4' whose name attribute is located at /home/jeremy/src/github.com/NixOS/nixpkgs-alt/pkgs/stdenv/generic/make-derivation.nix:336:7 … while evaluating attribute 'makeWrapperArgs' of derivation 'kicad-8.0.4' at /home/jeremy/src/github.com/NixOS/nixpkgs-alt/pkgs/applications/science/electronics/kicad/default.nix:201:3: 200| # We are emulating wrapGAppsHook3, along with other variables to the wrapper 201| makeWrapperArgs = with passthru.libraries; [ | ^ 202| "--prefix XDG_DATA_DIRS : ${base}/share" (stack trace truncated; use '--show-trace' to show the full, detailed trace) error: function 'anonymous lambda' called with unexpected argument 'python' at /home/jeremy/src/github.com/NixOS/nixpkgs-alt/pkgs/applications/science/electronics/kicad/addons/kikit.nix:2:1: 1| # For building the multiple addons that are in the kikit repo. 2| { stdenv | ^ 3| , bc Did you mean python3?

Other Project Repositories
The sources of all official Nix-related projects are in the NixOS organization on GitHub. Here are some of the main ones:
- Nix - the purely functional package manager
- NixOps - the tool to remotely deploy NixOS machines
- nixos-hardware - NixOS profiles to optimize settings for different hardware
- Nix RFCs - the formal process for making substantial changes to the community

Continuous Integration and Distribution
Nixpkgs and NixOS are built and tested by our continuous integration system, Hydra.
- Continuous package builds for unstable/master
- Continuous package builds for the NixOS 24.05 release
- Tests for unstable/master
- Tests for the NixOS 24.05 release
Artifacts successfully built with Hydra are published to cache at https://cache.nixos.org/. When successful build and test criteria are met, the Nixpkgs expressions are distributed via Nix channels.
