 ## [unreleased][unreleased]
+- Added --issue to hf iclass encode command (@micsen)
 - Added custom CTF Wiegand format from Defcon32 with comments (@micsen)
 - Added native output grabbing for Python and Lua: less hacky than `output_grabber.py`, should work on ProxSpace as well (@doegox)
 - Changed `hf mf chk/fchk`: added option `--no-default` to skip loading the usual ~61 hardcoded keys (@doegox)
