- `hf mf chk` Move main cycle to arm (Merlok)
- Changed proxmark command line parameter `flush` to `-f` or `-flush` (Merlok)
- Changed `hf 14a reader` to just reqest-anticilission-select sequence (Merlok)
+- Changed `hf 14a raw` - works with LED's and some exchange logic (Merlok)
### Fixed
- Changed start sequence in Qt mode (fix: short commands hangs main Qt thread) (Merlok)
- Added to proxmark ability to execute commands from stdin (pipe) (Merlok)
- Added `hf 14a info` and moved there functionality from `hf 14a reader` (Merlok)
- Added to `hf 14a info` detection of weak prng from Iceman1001 fork (Merlok)
+- Added to `hf 14a apdu` - exchange apdu via iso1443-4 (Merlok)
+- Added to `hf 14a apdu` - apdu and tlv results parser (Merlok)
