Chrome OS version 20 hits stable release channel
 

If you're a Chrome OS user who doesn't live on the bleeding edge, it's finally time to experience the latest version 20, which most notably adds support for its Drive cloud storage. Also mentioned as included in the upgrade is offline support of Google Docs, Pepper Flash upgrade, access to the new Aura UI on Cr-48 systems and other tweaks. Tighter integration with Drive and Docs may address a few of the issues noted in our review of v19, Chromebook and Chromebox owners can check it out as it arrives on their machines over the next several days and let us know if that's the case.
