X-Pro1 and 60mm - Firmware 2.01 changes?

I definitely don't think it is placebo, but I really think the ability to lock on focus in darker lighting has improved.  That was one of the big killers for me - as I only have the 60mm lens - I have often missed shots where there has not been enough contrast (even in quite bright lighting).  I just had a fiddle around today and took a few 'dummy' shots, but there seems to be an improvement.  Anybody else notice a change?

All we need now is min shutter selection on Auto ISO, and we are done and dusted.
