If you’re running a Chromebook or using ChromeOS Flex, you might’ve already received the second minor update for ChromeOS 136 that began rolling out on May 29, 2025. This update bumps your Chrome browser version from 136.0.7103.142 to 136.0.7103.150, with the platform version landing at 16238.62.0.
At first glance, this update might seem like just another quiet security patch. After all, Google didn’t publish detailed release notes until May 30, and even then, they didn’t offer much insight into what changed under the hood. But as with most ChromeOS updates, the devil’s in the details, and some of those details might just make you smile if you’re into clean design and subtle polish.
What’s in the Update?
Like most minor ChromeOS updates, this one primarily contains security fixes, bug patches, and minor system improvements. There’s no dramatic overhaul or shiny new app waiting to greet you after the reboot. But that doesn’t mean nothing changed.
We’ve been monitoring update deployment via cros.tech, and as of May 29, most supported devices have already been updated to this latest version. If yours hasn’t yet, give it some time or try manually checking for updates in the Settings app. Now, here’s something that caught our eye, literally.
If you’ve been tracking ChromeOS UI changes like we have, you might remember the saga of rounded window corners. It’s been a bit of a rollercoaster. First spotted back in ChromeOS 133 (Developer Channel), the new design gave app windows a smoother, more modern look. By ChromeOS 134, rounded corners were officially part of the stable release.
Then came ChromeOS 135, and inexplicably, those clean edges disappeared. We were back to square (and slightly sad) corners. But now? In ChromeOS 136, those beautifully subtle curves are back. Some of us had already noticed them in version 136.0.7103.142, so it’s not entirely clear whether the 136.0.7103.150 patch brought them back officially, or if they simply stuck around from earlier builds. Either way, we’re happy to report they’re here and looking better than ever.
It might sound like a small thing, but these little design details go a long way. The curved corners give ChromeOS a more unified aesthetic with Google’s broader Material You design language. Windows feel less boxy and more contemporary, like they actually belong in 2025.
Rounded Window Corners Make a Comeback
Yes, this was a minor update. Yes, most users won’t even notice a change. But for those of us who keep an eye on design consistency and UX polish, the return of rounded window corners is a welcome sight. It’s the kind of change that subtly but meaningfully improves your daily experience.
If you haven’t noticed any changes yet, don’t worry, it’s being gradually released. You can always enable the experimental flag to try it out early. We cover how to do that in this guide.
