Hi,
as now UE4.1 is released and I’m pretty sure that many other releases will follow in the next months (and years :)) I think it will be helpful to “Versionize” the Articles and Questions/Answers as the differences between Versions will be bigger and bigger in future.
What I mean is something like in MSDN (example Link: http://msdn.microsoft.com/en-us/library/system.drawing.bitmap.setpixel.aspx)
So there would be an standalone Article for each Version of the Engine.
An other approach would be to Tag the Articles with the Version numbers for which they are Valid.
So for Example the Article “Templates in C++” (https://wiki.unrealengine.com/Templates_in_C%2B%2B) should be tagged with all current Versions, but “Compiling For Linux” (https://wiki.unrealengine.com/Compiling_For_Linux) would be Valid only for v4.1
The way it is now will be also fine for the next few releases but after 1 or 2 years it can be complicated.
Best Regards,
