The Beta Channel for Chrome OS has a new update rolling out this morning that takes it onto the Chrome 65 train of the platform. The new build is 65.0.3325.65 (Platform version: 10323.30.0) for those keeping score at home and if you are in the Beta Channel, type chrome://help in the omnibar of the browser to force the update.
This is the first build in the Beta Channel based on Chrome 65, following up on three different Chrome 64 builds over the last half of January through the beginning of this month. Those with a keen eye will note that the build number is the same as the last Dev Channel build of the platform, which was released just yesterday.
As is often the case, the Chromium team within Google did not release a huge amount of details on what is in this new build. They just indicated that This build contains a number of bug fixes, security updates and feature enhancements.
Chrome 65 is expected to bring further security measures around sites and pop-up management but will also bring better external display scaling to the platform.
With Chrome 65 now in the Beta Channel, it is probably safe to assume that we will see it hit the production Stable Channel at the tail end of this month barring any unforeseen issues with it.
