How can I download DeepStream SDK 4.0?

I just found DeepStream SDK 3.0 only.

Hi YodaPaPa,

The DeepStream SDK 4.0 is at the last mile for releasing, please stay tuned.

We have released the DeepSteam SDK 4.0 last week, please try to move this new version for more features and supports, see https://devtalk.nvidia.com/default/topic/1057879/announcements/announcing-deepstream-sdk-4-0-/

Thanks
