## Rules

- File name: `CHANGELOG.md`.
- Versions in reverse chronological order (latest first).
- Dates in ISO 8601 format (`YYYY-MM-DD`).
- Always keep an `[Unreleased]` section at the top for upcoming changes.
- Each version and section must be linkable. Add comparison links at the bottom.
- Yanked releases: append `[YANKED]` after the date, e.g., `## [1.0.1] - 2026-02-01 [YANKED]`.
- Only include sections that have entries. Omit empty sections.
- One entry per line. Start with a capital letter and end with a period.
- Write for humans, not machines. Do not dump git log.

## Change Types

Use only these six types as `###` headings, in this order:

| Type | When |
|------|------|
| Added | New features |
| Changed | Changes in existing functionality |
| Deprecated | Soon-to-be-removed features |
| Removed | Now-removed features |
| Fixed | Bug fixes |
| Security | Vulnerability fixes |

## When Releasing

Move entries from `[Unreleased]` into a new version section with today's date.
Update the comparison links at the bottom of the file.
