Issue upgrading project from netcode .2 to .3

I'm getting some strange errors and i really don't know what to make of them. I've tried to remove and add the package again and re import all but to no avail. Has anyone else had this same problem upgrading to .3 ?

When I went into the code and check to see if there was a diff between the .3 code there was no diff. So I really think it got updated. What I'm wondering is if it's dependencies did too (transport maybe).

Edit just checked my transport and it should support .3

 

Figured it out based on the release post... There's no support for 2020.2 yet hence the bugs
