Chrome 33 implements the following new features and updates:
- CSS font-kerning - A CSS property to control text kerning.
- Custom Elements - Method for registering (creating) custom elements in script.
- Opus in MSE and <video> - Ability to play the open source WebRTC preferred audio codec - Opus in MSE and <video> tags on the for the webM and matroska containers. Please note that we have had Opus support in chromium since M25. This change enables Opus playback on MSE and <video> tags.
- Page Visibility API - Provides an API to ask whether the current tab is visible or not. If you, you might want to throttle back action or set an idle state.
- VTTCue - The VTTCue interface, part of WebVTT. Previously the members of VTTCue were on the TextTrackCue interface and there was a TextTrackCue constructor, now the VTTCue constructor must be used instead.
- Web Speech API (synthesis) - Enables web developers to incorporate speech synthesis into their web pages. Uses whatever the platform provides for synthesis.
- requestAutocomplete() - Allows a form to be filled out on demand by the browser's autofill. Particularly for mobile applications, this solves the problem of working with long or even multi-page forms. For merchants, this results in improved conversion rates, sorely needed in mobile purchase scenarios.
