Google has released a new beta of Chrome for Android today in the Play Store. The new build is version 65.0.3325.53, bringing the mobile browser up to the Chrome 65 version of the browser. The build is mostly a bug fix and building upon the current stable build of the browser.
As the name suggests, this new build of Chrome for Android is beta and while anyone can get the beta from the Play Store, it is recommended that it not be your primary browser. It can crash and there will likely still be bugs to be addressed. If you can live with that however, and need to do some testing, give it a try.
