Users can update to the latest release now using the browser’s built-in silent updater, or download it directly from google.com/chrome. The Omnibox changes are the most significant. It means that “based on the recency of websites visited, so you’ll get more contextually relevant suggestions at the right time.”
If you’ve been using Chrome for a very long time, omnibox will tailor its results more to what you’ve used it for in recent days and weeks as opposed to months and years. If you’ve only recently switched to Chrome, you will not see much difference for a while.
Chrome 29 for Android meanwhile has received WebRTC support, which enables real-time communication such as videoconferencing in the browser without installing any plugins.
