With over 175 renders, several quests, new locations and a ton of added frameworks for implants, prostitution, marriage and pregnancy, this is MoR's biggest update so far. 

NOTE! Don't forget to press the Update to 0.8.1 button if you're loading an older save. (Located on your Home interaction screen). 

As 0.8.1 now uses several array based systems, it might throw red errors at various places until you've updated. These errors are absolutely safe, however, and will not corrupt your game in any way. 

The changelog is too big to be posted here. 

Go check the wiki for additional information and hints on how to manage all that's new in this update:
