Bisecting regressions across dependencies

General Usage
6

I confirmed that this works. Thanks!

In details:

  1. In the pkg> prompt, type registry add git@github.com:JuliaRegistries/General. This creates a .julia/registries/General folder, which is a git clone of the general registry
  2. Go to .julia/registries and delete/rename General.toml, so that the default up-to-date registry is skipped. Pkg will fall back to the /General folder’s registry
  3. Go to /General, type git rev-list -1 --before="2026-01-22" master (with the desired date) to get the commit from that date.
  4. Check out that commit
  5. ]up your packages to get the packages from that date

Then git bisect etc. can be used inside /General to find the culprit.
