# Quick Task 260412-v5h: Generate CHANGELOG.md Summary

**Complete CHANGELOG.md with 11 version entries (Unreleased v0.6.0 + 10 tagged releases v0.1.0-v0.5.5) in Keep a Changelog format**

## Performance

- **Duration:** 2 min

- Retroactive entries for v0.1.0 through v0.5.5 with accurate feature lists
- GitHub compare links for all version pairs (including v1.0 tag alias for v0.1.0)

## Files Created/Modified

- `CHANGELOG.md` - Complete project changelog with 11 version entries, Keep a Changelog format, GitHub compare links

- v0.5.3 compare link uses tags/v0.5.3 as specified (actual tag name in git)

## Deviations from Plan

## Issues Encountered

None.

## Next Phase Readiness
