"Starting in June 2020, Skype for Windows 10 and Skype for Desktop are "becoming one" in the name of providing a consistent experience, says Microsoft's support page. But that doesn't mean there will be just one Skype client app for Windows 10. Microsoft is still continuing to make both versions of Skype for Windows 10 -- the Store app and the Desktop app -- available, with the Desktop version being downloadable from Skype.com.
As first noted by Neowin.net, the Skype for Windows 10 client is going from version 14 to 15 as of today, June 23. As indicated on a support page, the new client is getting a few new features, include support for nine videos in a video call. The other new features include:
Updated close options so you can quit Skype or stop it from starting automatically
Improved Tray icon, informing you about new messages and presence status
Share files directly from your File Explorer
Meet Now Improvements
Improved Call Controls
Microsoft also dropped support for a couple of features that were in version 14, specifically integration with the Share Charm and synchronization with Outlook contacts. The support page says these features "are not yet supported" on Skype for Windows 10.
