Any EM5 V1.5 quirks you've found?

My quirk is this, IBIS set to enable on half press, Panasonic 100-300 mounted with OIS on (by mistake).

The image is stabilized until half press, then no stabilization at all,  opposite to what one expects. Since at first I didn't realize I had the OIS on I thought that V1.5 had erroneously swapped the half press function. Glad to find out it was user error (again).  I never actually tried this before I updated so I'm assuming this is new to V1.5.

Any other quirks???
