Alpha channel support for WebM video enables transparency masking (a.k.a. green screen effects) in WebM videos.

Speech recognition with the JavaScript Web Speech API is now supported on Chrome for Android.

window.devicePixelRatio now takes full-page zoom (but not pinch zoom) into account.

Support for { alpha: false } in getContext('2d') lets you create an opaque canvas. This is similar to existing WebGL functionality and can improve the rendering performance of your app.

The Media Source API has been unprefixed and is now supported on Chrome for Android. It allows JavaScript to generate media streams for playback, addressing use cases like adaptive streaming and time shifting live streams.
