+"""
+This script updates a specific version's release notes section in CHANGELOG.md with new content
+or reformats existing content.
+
+The script:
+1. Takes a version number, changelog path, and optionally new content as input from environment variables
+2. Finds the section in the changelog for the specified version
+3. Either:
+   a) Replaces the content with new content if provided, or
+   b) Reformats existing content by:
+      - Removing the first two lines of the changeset format
+      - Ensuring version numbers are wrapped in square brackets
+4. Writes the updated changelog back to the file
+
+Environment Variables:
+    CHANGELOG_PATH: Path to the changelog file (defaults to 'CHANGELOG.md')
+    VERSION: The version number to update/format
+    PREV_VERSION: The previous version number (used to locate section boundaries)
+    NEW_CONTENT: Optional new content to insert for this version
