I was noticing on a file hosted on FMS 15.03 that there's a layout with a tab control layout object on it that renders differently between FMPA 15.03 and FMPA 16.01. In 16.01 the padding/spacing around the labels is different, this causes the labels to get chopped off at the far right: "Note" instead of "Notes". And you can see the size of the tabs are different. This is both at 100% zoom.
Here's a screen shot of the two clients. This is the exact same hosted file, each connected to from my machine (OS X 10.11.6). (These are running at the same time.)
