Adds a script and Makefile task to detect breaking changes between two versions of the codebase by: - Analyzing git diff to find file renames, deleted files, and code changes - Running old tests against new code with iterative LLM-powered patching - Generating specific, actionable migration guides with exact code examples - Add public API export analysis (compares __init__.py exports between versions) - Add GitHub release notes fetching and LLM-based extraction - Implement patch cycle prevention via hash tracking - Improve error parsing with better context extraction - Generate comprehensive migration reports with: - Documented breaking changes from release notes - Required code changes from test analysis - Automated migration commands - Detailed analysis combining all sources Usage: make breaking-changes OLD_TAG=v0.12.0 NEW_TAG=v0.13.0 Requires OPENAI_API_KEY environment variable.
