## [unreleased][unreleased]
- Add FlashMemory functionality (RDV40) (Thanks @willok)
- Fix 'hf mfu dump' - partial reads lead to corrupt data (Thanks @elafargue for pointing it out)
- 'hf mfu dumop / read' - now retries five times. (@jamchamb)
- Added `hf list mf` - deciphers crypto1 stream and works with first authentication and weak nested authentications (@Merlok)
