Evaluation jobs got about 30% faster thanks to a new tool: nix-ci-eval.
As part of this change, builds that are already known to be cached will now be skipped entirely. This brings the total worker time of the common case suite down by even more than 30%.
NixCI got a changelog, and this is its first entry.
Every change to NixCI gets an entry here from now on, so you can see what
shipped without having to ask.
Each entry is named for its version, like 26-07.1: a two-digit year, a month,
and a counter that starts again each month.
