We made a mistake with the release of Carbide Create 311 last week. The Windows build didn’t actually get updated, it was just 310 with a new build number.
To make things simple, we just incremented the build number and uploaded the correct versions of both the Windows and the OSX builds.
For OSX, 312 is the same as 311. For Windows, 312 now includes everything that should have been in 311.
Sorry for the confusion.
