The third Chrome 65 based beta build for Chrome OS has landed in the platforms Beta Channel today. Build 65.0.3325.107 (Platform version: 10323.46.0) is in the process of rolling out now but those who have a Chromebook in the beta channel can always force the update by typing chrome://help in the omnibar and checking for the update.
For those new to Chrome OS, the beta channel is the last channel a new build comes to prior to being released in the Stable channel. Generally there are anywhere from 2-4 updates to the Beta channel before it makes it out to the general public.
The release notes, per the norm, are sparse with this update. Only the generic and often used “This build contains a number of bug fixes, security updates and feature enhancements” is used to describe what is fixed or addressed. This, in a way, is a good thing. It suggest that the Chromium team is likely putting the final touches on the build to get it ready to be pushed into the Stable Channel.
It is possible that this will be the last Chrome 65 beta release. It is expect to be released to the Stable channel on March 13th and begin rolling out to devices shortly thereafter.
