 Version 1.0.8.1
  - Added the option for humans to start Biotech pregnancies if the DLC is enabled. If set, non-humans will use the old multiple pregnancy instead.
  - Properly track biotech pregnancy through labor.
+ - A biotech pregnancy will pause before going into labor if another womb already is in labor.
 
 Version 1.0.8.0
  - Support for RimWorld 1.4. All future changes to Menstruation will only be for Rimworld 1.4.
