@ -26,6 +26,7 @@ This project uses the changelog in accordance with [keepchangelog](http://keepac
- Changed start sequence in Qt mode (fix: short commands hangs main Qt thread) (Merlok)
- Changed driver file proxmark3.inf to support both old and new Product/Vendor IDs (piwi)
- Changed all command line parsers in `hf emv` commands to argtable (Merlok)
- Implemented AppNap API, fixing #283 and #627 OSX USB comm issues (AntiCat)
### Added
- Added `sc` smartcard (contact card) commands - reader, info, raw, upgrade, setclock, list (hardware version RDV4.0 only) must turn option on in makefile options (Willok, Iceman, marshmellow)
