- Mifare simulation, `hf mf sim` (was broken a long time) (@pwpiwi)
- Major improvements in LF area and data operations. (@marshmellow42, @iceman1001)
- Issues regarding LF simulation (@pwpiwi)
- Issue interpreting NXP "get sys info" command return value for icode tags. (@mjacksn)
### Added
- iClass functionality: full simulation of iclass tags, so tags can be simulated with data (not only CSN). Not yet support for write/update, but readers do not seem to enforce update. (@holiman).
