Currently we're using TNet 1.9.5b and I'd like to update us to TNet 2.0.0
We're on an iteration of Unity 4.3.4 and I'll probably update us to 4.3.7 soon. Is there a known reason that 4.5.3 and up is required now? It looks like we'll be stuck with the 4.3.X series until 5 is released (if we even switch to 5). I'll probably give it a try anyway but if you have a specific reason for requiring 4.5.3 I'll revert.
