Unity3d version 4.3
A new version of Unity3d was released recently.
We have been looking forward to a new release of Unity3d from our partners at Unity Technologies. The new version is kind of a milestone, because for the first time it now also comes with a dedicated and streamlined 2d workflow. They have also improved the Unity IDE and added new opportunities for windows apps. You can read more at Unity3d.com.
