 ## [unreleased][unreleased]
+- Changed `lf search` - it now tries to read and decode paxton id (@iceman1001)
 - Changed `lf search` - to identify hitag2/s/82xx in chipset detection to preserve their EM4100 or other outputs (@iceman1001)
 - Added `lf hitag hts reader` - to act as a HitagS / 82xx reader (@iceman1001)
 - Changed `lf hitag hts write` -> ´lf hitag hts wdbl` to fit rest of client command names (@iceman1001)
