- enhanced tracing: hf 14a list now shows meaningful timing information. With new option f it also shows the frame delay times (fdt) - small fix for hf 14b list - it used to run into the trace trailer - hf 14a sim now obeys iso14443 timing (fdt of 1172 or 1234 resp.) Note: you need to flash FPGA as well. More details in http://www.proxmark.org/forum/viewtopic.php?pid=9721#p9721
