Engine is unchanged since 3.1 you only need to update starbecue.pak if it is already installed If you are coming from older versions and want to read the actual new features rather than fixes, read the 3.1 release post
Changes
Tail Vore now has an interact trigger position when dialogue is disabled for an NPC
Radial menus when Dialogue is disabled should now ignore interact radius for pred/prey occupant interactions.
NPCs with dialogue disabled will open a radial menu if they have 2 or more actions available rather than use interact positions (unless their species is configured to always use interact positions, none are currently)
the Any Vore action now selects randomly from available vore types (In prior versions, if OV was available it would always do OV by merit of it being listed first)
The Any Vore action now will only be listed if there are 2 or more vore actions available
Lowered prey warp attempts before assuming player pred is offline from 4 to 2, and made the escape popup then appear immediately
Adjusted Rock candy names that were too long
Fixed minor oversight with NPC convert types
I forgot to upload the 3.1.2 fixes here, so here's them listed
