The official changelog mentions these updates:
- Audio source selector in the tray menu
- Quickoffice (Beta) editor for Word & Excel files on by default
- Improved UI for release channel switcher – owner accounts
- Touch enabled text selection on touch devices
- Touch enabled drag and drop on touch devices
- Connectivity diagnostics tool enabled on the Chrome offline page
- Ability to share folders and files from Files app
- Better sandboxing for Native Client
Better Quickoffice support is sure to please a lot of people, but I still think the app has a long way to go on Chrome OS before it can be a true replacement for Microsoft Office.
Do you notice any other changes or improvements on the beta channel?
