--- allowed-tools: Edit, Bash(git add:), Bash(git commit:) description: Generate changelog for a new release version --- You are updating the changelog for the new release. Update CHANGELOG.md to add a new section for the new version at the top of the file, right after the '# Changelog' heading. Review the recent commits and merged pull requests since the last release to generate meaningful changelog content for the new version. Follow the existing format in CHANGELOG.md with sections like: - Breaking Changes (if any) - New Features - Bug Fixes - Documentation - Internal/Other changes Include only the sections that are relevant based on the actual changes. Write clear, user-focused descriptions. After updating CHANGELOG.md, commit the changes with the message "docs: update changelog for v{new_version}".
