So unity 5 is out, YAY.
However I need to make an update to an asset on the asset store, and I opened it in 5 to upload for that, which is great. However now I cannot open it in unity 4 without the project imploding and scenes not opening.
So I want to support unity 4 and 5 so how am I meant to support them both when loading in unity 5 means I can no longer load in unity 4? I cannot see it being realistic to have 2 completely different repositories for each unity version, so there must be some logical way to handle this scenario in the same source control repository and not duplicating your core asset?
