I did some digging and it turns out that there are MAJOR changes to the way you move the cursor, select text, select words, etc. The "Loupe" feature seems to be available with a different gesture. The entire insertion point / caret has changed appearance. The changes are being touted as major advances in the way you navigate and edit text. But there are LOTS of complaints by people that the "loupe" feature is gone and people cannot see the cursor under their fat fingers (that's me, too).

Now you have to do a lot of three finger tapping, three finger pinching in, and three finger pinching out. Ugh.
