+# Changelog
+
+## v1.0.1 - 2025-01-23
+
+### Fixed
+- **CRITICAL:** Renamed `email/` directory to `email_processing/` to avoid namespace conflict with Python's built-in `email` module
+  - This fixes the `ImportError: cannot import name 'BytesParser' from partially initialized module 'email.parser'` error
+  - All imports updated accordingly
+  - No functional changes, only namespace fix
+
+### Changed
+- Updated all documentation to reflect new directory name
+- Updated Dockerfile to copy `email_processing/` instead of `email/`
+
+## v1.0.0 - 2025-01-23
+
+### Added
+- Modular architecture (27 files vs 1 monolith)
+- Batch DynamoDB operations (10x performance improvement)
+- Sender blocklist with wildcard support
+- LMTP direct delivery support
+- Enhanced metrics and monitoring
+- Comprehensive documentation (6 MD files)
+
+### Fixed
+- `signal.SIGINT` typo (was `signalIGINT`)
+- Missing S3 metadata audit trail for blocked emails
+- Inefficient DynamoDB calls (N calls → 1 batch call)
+- S3 delete error handling (proper retry logic)
+
+### Documentation
+- README.md - Full feature documentation
+- QUICKSTART.md - Quick deployment guide for your setup
+- ARCHITECTURE.md - Detailed system architecture
+- MIGRATION.md - Migration from monolith
+- COMPATIBILITY.md - 100% compatibility proof
+- SUMMARY.md - All improvements overview

 Adding new features is now easy:
 
 **Example: Add DKIM Signing**
-1. Create `email/dkim_signer.py`
+1. Create `email_processing/dkim_signer.py`
 2. Add to `worker.py`: `signed_bytes = dkim.sign(raw_bytes)`
 3. Done! No touching 800-line monolith
