how is unet on 5.4, 5.5, 5.6?

i've been locked into 5.3.7 for a looong time due to some really unfortunate VR "features" Unity introduced in 5.4 that made local 2 player testing impossible. without getting into it too much, i'm happy to report that those issues are no longer a deal breaker for me, so I COULD upgrade unity finally.

just wondering how people are getting along with newer versions of it for networking in particular. i've read a little bit about 5.6 having some low-level troubles which i don't think would interfere with my multiplayer project as I have completely decoupled from the low level api at this point.

it's easier to ask you guys about any weird pitfalls here instead of finding out for myself 80 hours later, so here i am

upgrading my unity version would generally be a real pain because of some extensive changes i've made to Unet, but it might be worth it for all the goodies that have been added over the months
