i just get a warning:
A new preview version of Skype for Web is available. Experience HD video calling, call recording and much more in your browser.
Tried to use it but it didn't work. And i saw an information at skype official site: You will need to be on Windows 10 or Mac OSX 10.12 or higher to use Skype for Web (Preview). For now, Skype for web is working with chromium on lubuntu perfectly. Will skype for web support for linux end?
