== Channels ==

The packages and modules hosted on Nixpkgs are sorted in various channels intended for various use-cases, and in practice are differentiated by the level of testing updates must pass on the official [https://nixos.org/hydra/manual/#idm140737315980672 nixos.org hydra instance] and the number of updates propagated to the channel. For [[Nix]] users, <code>nixpkgs-unstable</code> is the bleeding-edge, where packages pass only basic build tests and are upgraded continuously~~; for~~ [[NixOS]] users, <code>nixos-unstable</code> is the bleeding-edge, where packages pass build tests and integration tests on a VM. Both [[Nix]] and [[NixOS]] users can use stable channels - the latest being <code>nixos-17.09</code> - to receive only conservative updates for fixing critical bugs and security vulnerabilities.

For [[NixOS]] users, <code>nixos-unstable</code> is the bleeding-edge, where packages pass build tests and integration tests on a VM, and are tested from the perspective of being an operative system (this means things like the X server, KDE, various servers, and lower level details like installing bootloaders and runnning the nixos installation steps are also tested).

Both [[Nix]] and [[NixOS]] users can use stable channels - the latest being <code>nixos-17.09</code> - to receive only conservative updates for fixing critical bugs and security vulnerabilities.
