v4

Added

• Validation that every released ## [version] section has a trailing release date in the format - YYYY-MM-DD, and that [Unreleased] does not.

Fixed

• extract/action.yml's mdq selector was invalid syntax and silently failed to match dated version headings (e.g. ## [1.7.1] - 2026-08-31). Replaced with an anchored regex selector that matches whether or not the heading resolves as a reference link, without colliding on version-prefix overlaps (e.g. 1.1 vs 1.10).

v3

Added

• extract/action.yml sub-action that extracts a single version's section from a Keep a Changelog file (via mdq), for driving GitHub release notes from the changelog.
• .github/workflows/release.yml — pushing a v* tag now validates the changelog, extracts the matching section, and creates a GitHub release from it, failing if no matching section is found.
• README.md and this CHANGELOG.md.

Changed

• Moved validation logic into validate/action.yml + validate/index.js, now directly callable as its own sub-action alongside extract/. The root action is unchanged for existing consumers.
