A new version of the scriptable multi-emulator/frontend/media swizz-army-knife Arcan(Linux/BSD/Windows) has been released.

The major new features include:

• Tool for streaming
  
• Networked remote control / secondary displays
  
• Upscalers
  
• Runtime performance / graphing / debugging

Arcan uses a combination of libretro (same interface as RetroArch) and so interpositioning (Linux/BSD only) to run multiple emulation sessions in parallel - in addition to video decoding and encoding. These can then be scripted, transformed and otherwise manipulated using a reasonably simple LUA API (wiki at http://sourceforge.net/p/arcanfe/wiki/Home/).
