Version 3.2's main two features are the new after sex animations, and the pokedex.
Now, when you switch out to the next pokemon, the previous one will lie next to you in the bed, resting. The mess under her tail is dynamically rendered based on how much time you spent with her, including animated rivulets and a creamy forming puddle. Their facial express may also change based on what happened.
As for the pokedex, it will act as the game's main interface here on out. You can access the cheat controls here, music and sound toggles, swap out pokemon, read their adult orientated pokedex entry, and in the future, customize their appearance, and even use the screen to view x-ray mode. I spent a fairly long time working on it since it'll be used as a global feature. I'm still working on the interface, so here's just a picture of the boot sequence.
I estimate 3.2 will be ready sometime ealy September. This will be the last 3.x release before 4.0 which will finally introduce some new positions and different types of pokemon.
