Nothing a caller can observe changes. No export was added, removed or altered, and no call answers differently. Upgrading is safe and optional.
What moved is the documentation and one gate.
- The README leads with the defect daymath prevents, and the calendar rule and CDN forensics moved to
docs/calendars.mdanddocs/cdn.md. Both joined the examples gate in the same commit, so every claim they carry is still executed and asserted. npm run test:examples:tzruns every prose claim in three fixed-offset zones. The gate had only ever run in whatever zone the machine was set to, which let a zone-dependent claim pass on a laptop and fail in CI.npm cino longer warns about theesbuildinstall script under npm 11.19.- A code of conduct, issue templates and a pull request template.
The full mechanism, the defects found on the way, and the commands that prove each one are in CHANGELOG.md.
