• Added issue and PR templates
• Set up automated security scanning

Migration Guide

From 2.0.x to 2.1.x

Security Changes

The torch.load() calls now use weights_only=True. If you have custom checkpoint loading code, ensure your checkpoints are compatible:

# Old (potentially unsafe)
model.load_state_dict(torch.load(path, map_location=device))

# New (secure)
model.load_state_dict(torch.load(path, map_location=device, weights_only=True))

Testing Changes

If you're running tests, note the new pytest configuration:

# Run all tests
pytest tests/ -v

# Run only unit tests
pytest tests/ -m "unit"

# Skip CUDA tests (CPU only)
pytest tests/ -m "not cuda"

Deprecation Notices

None currently.
