# This script:
# 1. parses the version number from the branch name
# 2. updates version.py files to match that version
# 3. iterates through CHANGELOG.md files and updates any files containing
# unreleased changes
# 4. sets the output variable 'version_updated' to determine whether
# the github action to create a pull request should run. this allows
# maintainers to merge changes back into the release branch without
# triggering unnecessary pull requests
