update-changelog-md

Add a new version entry to CHANGELOG.md , or restructure the entire file, following the Keep a Changelog format and Semantic Versioning.

Workflow — new version entry

• Read CHANGELOG.md to identify the last released version and its date.

• Run git log --oneline <last-tag>..HEAD to list all commits since that tag. If no tag exists for the last version, use git log --oneline and filter manually.

• Run date +%Y-%m-%d to get today's release date — never hardcode it.

• Determine the new version number (ask the user if not specified):

• MAJOR bump: breaking changes or major redesign.

• MINOR bump: new features, backward-compatible.

• PATCH bump: bug fixes only.

• Group commits into Keep a Changelog sections (see Section rules below).

• Prepend the new version block immediately after the file header (before the previous latest version).

• Do NOT remove or alter any existing version entries.

Workflow — restructure entire CHANGELOG.md

• Read the full CHANGELOG.md and note all existing version blocks.

• Rewrite the file preserving all versions and dates but enforcing:

• Correct header and intro paragraph (see File header below).

• Consistent section names and ordering.

• Bullet style: start each item with a capital letter, no trailing period.

• Run date +%Y-%m-%d and confirm the latest version date is still accurate.

Section rules

Use only these standard Keep a Changelog section names, in this order when multiple sections are present:

Section When to use

Added

New features or capabilities

Changed

Changes to existing behavior

Deprecated

Features marked for future removal

Removed

Features removed in this release

Fixed

Bug fixes

Security

Security-related fixes or improvements

Commit → section mapping heuristics

• feat: / add / new → Added

• refactor: / change / rename / move / update / improve → Changed

• fix: / bug / patch → Fixed

• remove: / delete / drop → Removed

• deprecate: → Deprecated

• security: / cve / vuln → Security

• docs: / chore: / ci: / test: — omit unless user-facing.

When a commit message is ambiguous, infer intent from the diff or file name.

Style rules

• Write in English throughout.

• Each bullet: capital letter, present tense, no trailing period. Example: Add retry logic for HTTP requests

• Keep bullets concise — one line per entry where possible.

• Wrap code identifiers, file paths, and module names in backticks.

• Never guess dates — always use date +%Y-%m-%d .
