Chrome stable just hit version 21, so you can move back to stable from Canary if you have a Retina MacBook Pro. Other goodies include:

  • Chrome now includes the getUserMedia API, which lets you grant web apps access to your camera and microphone without a plug-in. The getUserMedia API is the first step in WebRTC, a new real-time communications standard which aims to allow high-quality video and audio communication on the web.
  • The getUserMedia API also allows web apps to create awesome new experiences like Webcam Toyand Magic Xylophone. In Chrome Web Lab, if you’re on the latest version of Chrome, theSketchbots experiment uses getUserMedia to let you take a picture of your face, which is then converted to a line drawing and sent to a robot in the Science Museum in London. The robot then draws out your portrait in a patch of sand, which you can watch live on YouTube and visitors can watch in person at the museum. It’s just about as crazy as it sounds, and twice as cool.
  • In addition, today’s Stable channel release includes deeper Google Cloud Print integration,expanded support for gamepads, and support for high-resolution Mac Retina screens. To check it all out, just download Google Chrome.
