+Version 1.0.7.1
+ - Identical twins conceived after this update will have identical sex part sizes, properties, etc. upon being born.
+ - Race modders: The function Hediff_MultiplePregnancy.ProcessIdenticalZygote is called on every identical sibling when born except the first. Feel free to patch race-specific things into it.

 Version 1.0.7.0
  - Not save compatible with previous versions. Expect glitches and many red errors if you try. However, things should stabilize eventually.
  - Designed for RJW 5.0.0, but should work with previous versions.
