Google has updated the stable channel of Chrome OS to version 20.0.1322.54 for Chromebooks (Acer AC700, Samsung Series 5, Samsung Chromebook Series 5 550, and Samsung Chromebox Series 3, and Cr-48). Users running any of these devices should be getting updates over the next few days.
There are some major improvements in the stable channel which Beta users are already familiar with. I am running Dev and Beta channels on my two Chromebooks so, I don't know what state Stable was in, but if you are an stable user these are the improvements you will notice:
- Support for Google Drive
- Offline support of Google Docs
- Firmware update for Chromebook Series 5 550. Note: A screen with Chrome Logo and a critical update notification will show after update restarts. It will reboot by itself after firmware update completes.
- Updates to Pepper Flash
- Introduced redesigned UI to Cr-48 systems
- Switched to open source touchpad driver on Cr-48 systems
You can easily switch between channels on your Chromebook. Just visit the About Chrome OS page and select the preferred channel.
