After releasing Chrome 62 for Android OS and browsers, Google’s Chrome team is now rolling out Chrome OS 62. The Chrome OS 61 brought a Pixel-style launcher along with new lock screen, Chrome OS 62 picks up from there and brings an overhauled Android-like notification panel to Chrome OS. However, the most critical security change addresses the KRACK Wi-Fi vulnerability.

With the addition of Android app on Chrome OS, there was a difference in notifications appearance for Android apps and the ones from the Play Store. Chrome 62 bridges this divide and adopts Android style appearance of notifications for Chrome apps too. Now, Chrome apps also feature smaller icons, app name, and time, alongside revamped notification action buttons beneath. The design of the entire OS now looks more uniform and pleasing to the eyes.
