The Chromium team has released a minor update to Chrome OS for the majority of devices today. The update takes the build version up to 54.0.2840.93 (Platform version: 8743.83.0) for those keeping score at home. If you remember, the first major build of the 54 train was released a couple of weeks ago. This update is much smaller and generally addresses some security fixes which Google did not disclose the full details of in the release.
The update however is not for all devices. If you have a HP Chromebook 13 G1, Acer Chromebook 14 for Work and Thinkpad 13 Chromebook then the update will not be coming to your devices – not yet at least. If you remember, these are the same models that didn’t get the original 54 train so it stands to reason on why this minor update didn’t touch these devices as well.
This update to Chrome OS should be coming to eligible devices over the course of the next few days. You can, of course, force
your machine to go look for it by typing in chrome://help in the browser and it will go out and look for the update and download it for you automatically.
As for when the excluded devices will get the update, that’s a bit of a mystery.
