Comparison vs existing "old" 1.3 SDK?

Hi,
I see download coming soon but on gameworks site we have already v1.3 since late 2017…
(https://developer.nvidia.com/gameworksdownload#?search=aftermath)
just curious what’s new compared to existing “Aftermath 1.3 (Windows)”?
also I see “Turing based GPUs”…
as I’m on Titan V (Volta) seems new SDK wouldn’t be supported and have to use existing 1.3…
also seems DX11 support has been lost in new version?
as I see GFSDK_Aftermath_DX11_Initialize on old SDK…
thanks…

sorry posted two times!
