It's been a long time since Microsoft last shared what's new in the latest Skype updates. The app has been getting updates somewhat consistently, and Insiders are now up to version 8.46, but the last time we had heard anything new was for version 8.43 in April.
That's changing though, as the team has shared that, with version 18.104.22.168, Skype for Web now supports screen sharing, even if you'll need to be using Google Chrome. Since Microsoft's new Edge browser is based on Chromium, it's possible that the feature also works there, but the company didn't specifically say so.
Screen sharing has long been a major part of the Skype feature set, and Microsoft has been bringing it to more platforms recently. Back in April, the feature made its way to the mobile apps, where screen sharing isn't as common of a feature. With its arrival on the web app, it's now available on all the platforms where Skype v8 is available, even if the web version is limited to a specific browser for now.
