+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.

+- 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}".
