What’s fixed

• The Updates screen showed only “Up to date” when you were already on the newest release, hiding every release’s notes. It now lists them whatever version you are on, with the one you are running marked.

Changed

• package-lock.json is shared, not ours alone: a site with its own theme or packages has to change it. An upgrade now rebuilds it with npm install rather than installing from it, so a merged lockfile repairs itself. Upgrade: if git reports a conflict on it, take either side and run npm install — the result is the same either way, and commit it.
• db/schema.rb is yours, and Nibble no longer ships one. It is generated from migrations, so two copies of it — ours and yours — conflicted on every upgrade that carried a migration, on a file neither of us edits by hand. Upgrade: the merge removes our copy. Run bin/rails db:prepare to regenerate yours, then commit it. If git reports a conflict on it instead, keep your side and run the same command.
