latest PWE SDK is over 2 years old now, should we expect anything newer?
The current version of the ProjectWise SDK is 10.00.03.262. I don't know when the next release will happen, but probably (my guess) is when ProjectWise Design Integration CONNECT Edition Server v10.00.04.xxx is released.
The current version is valid for all the released versions of ProjectWise Explore and Design Integration Server v10.00.03.262 or later. Is there specific functionality that is in the version of ProjectWise that you are developing for that the ProjectWise SDK does not include?
