Yealink T48G firmware versions?

Any problems with going with whatever the latest firmware for the T48G is? Or are there some specific versions to stay away from? I only ask because I’ve previously had some trouble with some Aastra firmware on 9133 or 9143i phones and backing up a version or two fixed it. So I thought I’d ask before just jumping to the latest and greatest.

I’m using BETA-6.12.65-15 (FreePBX 12) with Asterisk 12.
