Lix makes its second release

Lix, the fork of Nix that LWN covered in July, has made its second release since forking. This one includes substantial changes to the backend code, including removing a dependency on Bison, and getting a change to the Nix language back upstream.

The general theme of Lix 2.91 is to perform another wave ofrefactorings and design improvements in preparation for our evolutionplans.

Nevertheless, there are a few exciting user facing changes[.]
