Google Chrome 21.0.1180.60 has been updated to the Stable channel for Windows and Chrome Frame, 21.0.1180.57 for Mac and Linux. This release 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 Toy and Magic Xylophone. In Chrome Web Lab, if you're on the latest version of Chrome, the Sketchbots 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.
Google Chrome 21 Stable also includes deeper Google Cloud Print integration, expanded support for gamepads, and support for high-resolution Mac Retina screens.
In addition, Google Chrome 21 Stable address multiple vulnerabilities. These vulnerabilities may allow an attacker to execute arbitrary code or cause a denial-of-service condition.
