Update: Release 5

Literally thousands of changes, improvements and bug fixes. Too many to list here, but here are the biggies:
The Windows version is compatible with all VR headsets that are able to connect to SteamVR. The system auto-selects what to use, but it tries Oculus, first. If you have an Oculus headset, start Oculus Link before starting the program or it will shunt you into SteamVR.
The Windows version version now runs significantly more efficiently. Graphics now take about 2/3 of their previous overhead, so you may see more stable framerates or lower energy use as a consequence.
The Windows version on Oculus headsets now takes about 1/2 the video bandwidth as the previous version. Passthrough should look better as a consequence. Still use USB 3, though, or the framerate on the camera isn’t very good.
The Quest version now runs at 90FPS.
The Quest version now has an adaptive resolution system to improve performance.
A centralized localization system has been added to serve and process language information in multiple languages. Some menus are translated but most are not, so this needs data added to work.
Menus have been entirely reworked. Graphically better, more options, better performance, etc…
Controllers in Oculus and SteamVR now do a little haptic tick when you push a menu button.
The Quadruped Test version has two additional friend characters that you can have sex with standing up, and have a unique interaction option that bipeds don’t have yet.
