  • The Lightstream client is being retired to make room for a new and improved version in a future release. If you need to capture gameplay, we suggest using an RTMP Source.

    • Download link for the client has been removed.
    • Layers in existing projects that require the client have been removed.


  • Forget me not. Image slideshows will consistently maintain their edits.
  • Uncrossed the wires that would cause Studio to not load properly in some cases.
  • Corrected an issue causing connected layers to erroneously show as disconnected.
  • Changing microphones via the audio mixer now correctly switches source. Guest microphones are now accurately reported here.

  • Improved consistency and speed of load time for browser capture, cameras, and microphones.
