For those of you who want to create your own games and apps for the Playstation Vita, the open beta is still going on, and Sony issued an update to their SDK yesterday.The main change is not super exciting: the name of the program is now Playstation Mobile, while it was known as Playstation Suite until now (no doubt that people will still be calling it that for a while). But Sony also adding In-App purchase functionality, a feature that fans of Free To Play were probably eagerly waiting for.
The changelog is as follow:

  • In-App Purchase library
  • Digital Signature & Encryption library for content protection
  • GamePad support for UI Toolkit library
  • ModelViewer for previewing .mdx files on PC
  • 50+ bug fixes

It’s worth noting that given its new name, this SDK will probably never be officially made available for the PS3, which was one of the things some developers were hoping for.
