It looks like there is a lot of great new features coming out in Unity 5.0 but one of the questions I had is does Unity 5 now support streaming asset bundles from earlier unity versions? For example, if I create a asset bundle in Unity 5.0 and then a few minor releases later say Unity 5.5 will I still be able to stream and load the same unchanged asset bundled to a iOS device without having to re-build it? I know there is still cross platform building but thats a different issue. Will the new ignoretypetreechanges build option solve this problem? If so, what are the cons here?
