How Can I Manually Update My Chromebook and/or Check The Version?
Generally, we set Chromebooks to update to the most recent stable channel. You can check the version and/or update by opening Chrome and clicking the 3 bars in the upper right, then click settings. At the top, click the text that says "About This OS". You'll see the version number and a button to check for updates. (This button may say restart if updates were already loaded.)
Here is a video that shows a method for checking updates. If your Chromebook will not update to a more current and stable version, please open a new ticket.
