v4.0.0

The next version of Grapejuice is finally here! It took a while, but Grapejuice 4 is finally finished. This new version of Grapejuice has a completely redesigned user interface and comes with a bunch of new features!

Grapejuice can now manage multiple wineprefixes. As time went on, it became apparent that a lot of Wine fixes that work awesomely for the player, break Studio. So to ensure both applications can work properly on the same computer, Grapejuice will now manage at least two wineprefixes. You can now fully trick out the prefix for the player with all sorts of performance tweaks, while maintaining a stable Studio experience.

One of the primary performance tweaks is now semi-automated: Grapejuice will now attempt to set a rendering fast flag depending on what hardware you have in your computer. The default DirectX 11 renderer can perform very poorly running in Wine. Roblox' Vulkan and OpenGL renderers perform way better on most hardware.

Nothing is perfect, and neither is Grapejuice. A new exception viewer graphical interface has been added. This window will show whenever Grapejuice runs into a problem. It will now also pop up if something goes wrong when launching Roblox from the website, so you're no longer left hanging when something goes wrong while starting Roblox.

Historically the settings section in the Grapejuice UI was severely lacking. The new user interface now exposes most of the settings available.
