I've been sidetracked with other things so I haven't gotten to it, and my net connection isn't stable enough to do any work at the moment, but I have glanced at it.
In a nutshell, US 30, OR 99, 99E and 138 (the three OR routes weren't part of that update) need to be synced to I-5.
I-84 needs to be synced to US 30.
I-405 needs to be synced to US 26 and 30 (I-405 wasn't part of the update and possibly to I-5 at the southern terminus.
The US 20/26 overlap should be fine, but OR 201 might need to be synced.
US 395 might need syncing to I-82, US 30 then I-84, US 26 and 20 (OR 140 wasn't done yet).
OR 34 should be good along US 20, but OR 99W, 99E and 126 might not be.
OR 200 along 36 may be slightly off.
Those are all the overlaps in Oregon I can think of off the top of my head.
