## Notes

- Change types: `added` (Added: new feature or capability), `improved` (Improved: enhancement to existing behaviour), `fixed` (Fixed: bug fix), `removed` (Removed: feature removed), `deprecated` (Deprecated: still works, will be removed), `security` (Security: security-related change). In Markdown each change is a list item starting with the bold label, e.g. `- **Fixed:** …`; `(breaking)` after the label means the change requires user action.
- Versions follow semver-style precedence (1–4 numeric parts, optional pre-release such as `3.0.0-beta.1`). "Latest" is always the highest **stable** published version by precedence — never the most recently published one — so a back-ported hotfix or a beta never becomes latest. A leading `v` is accepted in URLs.
- Channels: `stable` builds drive "latest"; `beta` builds are listed and labelled but never reported as latest.
- Statuses: `published` releases are public, in feeds and eligible for latest; `archived` releases stay reachable at their permalink (marked archived) but are excluded from lists, feeds and latest; drafts are never public.
- Dates are ISO 8601 in JSON and feeds; calendar dates in Markdown are in the UTC time zone.
- JSON, feeds and Markdown are all generated from the same data; the JSON API is versioned with the `X-API-Version` header and supports conditional requests (ETag / Last-Modified) and CORS for browsers.

## Optional
