- Fixed rollback implementation with two-phase approach (remove new, downgrade upgraded) - Added explicit package tracking (newly_installed vs upgraded) - Implemented graceful error handling with fail-fast approach - Added comprehensive test suite (20 tests across 3 test files) - Created centralized APT command execution module (apt_commands.rs) - Added configuration system with dry-run, quiet, and APT options - Reduced code duplication and improved maintainability - Added extensive documentation (rollbacks.md, rollbacks-not-featured.md, ffi-bridge.md) - Created configuration usage example - Updated README with crate usage instructions - All tests passing, clean compilation, production-ready
