[chirp_users] New UV-5R BFB291 Firmware Problems

I am new to this list, so please forgive me for asking the obvious question. I have checked the FAQ and did not find my answer. I recently purchased two Baofeng UV-5R, firmware BFB291. I am unable to program these radio with Chirp software. Any idea when update for Chirp will handle this new firmware? I tried using factory software and getting communication errors. I would prefer using Chirp.

Any suggestions?
