Google has released a major update for Chrome OS, which brings with it several changes. For starters, there is now a new Chrome OS Launcher, which has better search experience, voice search, and Google Now integration.
Other than that there is also a new Files app, which has been updated with new Material Design interface. Other changes include a new Calculator app, support for password-protected ZIP files, and default typeface on all Chromebooks being updated to Roboto Latin, Greek and Cyrillic scripts.
The update has started rolling out and will be available in the next two weeks.
