Changelog Maintenance

Core Workflow

1. Identify the changelog format, current version, target version, and source of changes.
2. Preserve existing structure and style unless the user asks for a migration.
3. Add concise entries under stable categories such as Added, Changed, Fixed, Deprecated, Removed, Security, and Docs.
4. Move completed Unreleased entries into a version section when preparing a release.
5. Keep issue, PR, and commit references only when they are useful and accurate.
6. Note breaking changes and migration requirements prominently.

Safety Rules

• Do not invent change history, issue numbers, contributors, dates, or fixes.
• Do not rewrite historical entries unless asked.
• Do not hide breaking changes or security-relevant notes.
