And a new manual update.

Looks like they added a check of the battery voltage before doing a firmware update in the latest release. Sounds like a good idea.

I'm still not thrilled with resistance mode.  It is still somewhat slow, but putting the two leads together, it takes 2.5 seconds and then readings float between .018 to .103 ohms.  The longer you hold the leads together the more the resistance reading goes up.  V2.02, I believe is better than v2.00 in resistance.  I've swapped leads and same thing.  Perhaps the leads I have are not ideal, but resistance readings so sluggish make it hard to use for trouble-shooting.  Its hard to know when to press the REL button as it takes a while for the readings to settle down when shorting the leads together.

On another subject, has anyone thought to do some customer firmware for working on older automobiles?   I want to read RPM with a clamp-on probe (already have) and then drell angle (not real familiar with that).  I am fixing-up (not down, but it is currently - lol) a 1974 Beetle as a hobby.  I bought an automotive meter that is supposed to do this, but what a piece of fragile crap.  RPM is basically reading frequency.  I couldn't get that meter to read the RPM consistently.  I have no idea what dwell angle is, but when I get to tuning the engine they say at a certain RPM set the timing for a dwell angle of xx.  Anywho, I don't expect that, but did wonder if people have been doing customer firmware for this meter.
