Update Changelog

Update docs/CHANGELOG.md from repository evidence instead of guesswork.

When to Use

• Add the newest release entry to docs/CHANGELOG.md
• Sync changelog text with GitHub Releases
• Summarize the latest tag from git history or code diffs

Defaults

• Keep the wording brief
• Only add the latest missing version unless the user explicitly asks to backfill older releases
• Prefer GitHub sources first, especially Releases and tag metadata
• Skip Features / Improvements / Bug Fixes headings when the release only has a few clear items

Procedure

1. Read the local style

• Open docs/CHANGELOG.md
• Match the existing tone, bullet style, section ordering, and date format

2. Determine the target release

• Read the root package.json version and compare it with the top changelog entry
• Find the previous tag for the target version
• If the latest version is already documented, stop and report that no changelog update is needed

3. Gather evidence

Prefer these sources in order:

1. GitHub release notes

GH_PAGER=cat gh release view v<version> --repo <owner>/<repo> --json tagName,name,publishedAt,body

2. Tag date

git log -1 --format=%cs v<version>

3. Commit history between tags

git --no-pager log --format='%h %s' --no-merges v<previous>..v<version>

4. Diff scope when commit subjects are vague

git --no-pager diff --name-only v<previous>..v<version>
git --no-pager diff --stat v<previous>..v<version>

5. Read touched files directly only when the user-visible change is still unclear

4. Distill what belongs in the changelog

Include:

• User-visible features
• Important behavior changes
• Bug fixes that improve reliability, compatibility, or developer experience
• Small docs updates only when they materially change supported setups or onboarding

Exclude unless explicitly requested:

• Pure version bumps
• Routine dependency updates
• Internal refactors with no visible impact
• Mechanical formatting noise

5. Choose the structure

• If the release has 1 to 3 clear points, write flat bullets directly under the version heading
• If the release has several distinct items, use short headings such as ### Features, ### Improvements, and ### Bug Fixes
• Do not force categories when they make the entry longer or noisier

6. Write the entry

• Add or update only the requested release entry
• Keep bullets short and concrete
• Reuse project terminology from nearby entries
• Avoid marketing language
• Do not copy noisy GitHub release text verbatim

7. Verify

• Check dates, version numbers, and tag boundaries
• Ensure Markdown structure matches nearby entries
• Confirm no intermediate versions were added unless requested

Completion Checks

• The newest requested version is documented
• The wording is concise and consistent with the surrounding changelog
• The entry is backed by GitHub releases, git history, or code diff evidence
• Low-signal internal changes were left out
