## [unreleased][unreleased]
+### Added
+- ISO14443a stand-alone operation with ARM CFLAG="WITH_ISO14443a_StandAlone". This code can read & emulate two banks of 14a tag UIDs and write to "magic" cards (Craig Young)
+
+### Added
+- AWID26 command context added as 'lf awid' containing realtime demodulation as well as cloning/simulation based on tag numbers (Craig Young)
+
### Changed
- EPA functions (`hf epa`) now support both ISO 14443-A and 14443-B cards (frederikmoellers)
#remove one of the following defines and comment out the relevant line
#in the next section to remove that particular feature from compilation
