Usability tweaks and behind-the-scenes improvements for nearly all Chromebooks
The Stable channel of Chrome OS is being updated today to version 29.0.1547.57 for all Chromebooks (except the Lenovo Thinkpad X131e) with several improvements. First up is a new "immersive mode", which hides some of the chrome (pardon the pun) around windows and provides a nearly full-screen experience.
The app launcher has also received a few tweaks, letting you pin apps to the shelf from the launcher with a simple drag-and-drop. The app launcher search has learned a few new tricks as well — it will dynamically learn what you search for most regularly, prominently highlight apps and offer web store results if you don't have an app installed.
Some behind-the-scenes improvements like a move to kernel version 3.8, wallpaper sync across Chromebook devices, two finger history navigation and fixes for monitor scaling are all included in this update as well. Be on the lookout for the download on your own Chromebook today.
