AI-Generated Summary

Summary of changes in this PR:

• Added a new script generate_release_notes.py to automate creation of release notes from git commits.
• The script performs the following functions:
  • Retrieves commits between specified git tags or from the latest tag.
  • Categorizes commits based on conventional commit prefixes such as feat, fix, docs, etc.
  • Formats the categorized commit information into a structured release notes format suitable for processing with a language model.
• Key command line options include:
  • --tag: Specify the current tag for generating notes (default is the latest tag).
  • --previous-tag: Specify the previous tag for comparison (default is detected automatically).
  • --output: Output file for release notes content, defaults to stdout if not specified.
• This new functionality can streamline the release process and improve the quality of release documentation by providing structured information directly from commit history.
