Unity 5

This fall, Unity 5 will be making its debut. Unity 5 was announced at the 2014 Game Developers Conference, including its features, but lately we have seen some previews of these features.

Unity will feature some new scripting shortcuts, and to help developers their existing scripts will automatically update to use the new shortcuts. Another post on the Unity Blog shows new animation features coming in Unity 5

Their are also some changes coming to the Audio system in Unity 5:

Unity for PlayStation® Mobile

Unity announced that all developers in the PSM Developer Program can publish their Unity content to PlayStation® Store and target both the PlayStation® Vita handheld and the new PlayStation® TV, completely free of charge. A special build of the Unity Engine with the PSM build option was released, but should be available in all Unity builds soon (if it is not already).

Note that in order to publish a game to the PlayStation Store, developers must register with Sony.
