HTTP/2 is available for IIS 10 on Windows Server 2016 but there is no news about it being added to Windows Server 2012 and IIS 8.
I haven't found much searching the internet but does anyone know if Microsoft has officially said anything (either a yes or a no of adding support)?
Most people are guessing that Microsoft will not be updating Windows Server 2012 to support HTTP/2.
This really will be a bad move on MS's part.
