I'm trying to understand a bit better what exactly were the changes between Victoria 4.0, 4.1 and now 4.2.  Specifically, I'm most interested to how the base V4 .obj file changed during this progression.  As I understand it:

4.0 - The first release of V4.  Base model plus Morphs ++ package

4.1 - Second release of V4. Introduced eyebrow object in base .obj file.  Also added external morph injection files for external morph packages like muscle morphs.  Morphs ++ package not changed

4.2 - Third release of V4 ???

Can someone please enlighten me.  I never upgraded to 4.1 becuase I didn't have a need to use the DAZ external injection morphs since I use the old internal PBMCC channels for morph injection.  I'm worried now because from what I've read, the 4.2 object file has changed which could potentially cause problems with internal morphs created on older versions of V4.
