We are about to embark on upgrading from V3.1.5 to V4.0.5 since later versions of Unity are not compatible with V3 in regards to digital networking. We will be in a mixed enviroment for a while. All new servers on V4 and old V3 servers are to be retired.
Is there any driver or urgency that would encourages us to upgrade to V4.2 quickly from V4.0.5?
Thanks in advance,
Jack
