Changed

• Everything of Nibble’s now lives under lib/nibble/, and app/ is yours. Your models, controllers, jobs and views sit where a Rails application puts them, with nothing of ours beside them, and your views are looked in before Nibble’s. Class names are unchanged. Upgrade: if you added files under app/, they stay exactly where they are and keep working. If you had changed one of Nibble’s files in place — which bin/rails nibble:check reports — git will stop on it during the merge, because that file has moved.
• bin/rails nibble:check no longer reports files you added under a directory Nibble also uses as edits to ours. It reports what you changed or deleted of Nibble’s, which is what an upgrade can actually stop on.
• .github/ is gone. Workflows and dependency updates of ours have no business running in your repository, against your budget, on rules you did not write — and a site is a clone, so the only way not to send them is not to have them. bin/ci runs every check Nibble runs on itself. .github/ is yours, empty or otherwise. Upgrade: taking this release deletes our copy from your tree. If you had put your own workflows there, git stops on the conflict — keep your side.

What’s new

• site/test/ is yours for your own tests, run by bin/ci and by bin/rails test site/test, with Nibble’s test_helper available. Nibble’s own tests stay in test/.
• The README says how to send a change back rather than carry it, and states the ownership rule in one line.
