when is VRWorks 360 Video SDK going to be released?

the VRWorks 360 Video SDK was supposed to be ready late 2016. is it coming soon?
If it is not coming, are there any alternatives?

The one relevant NVIDIA web page I could find, https://blogs.nvidia.com/blog/2016/07/25/360-degree-video-stitching/, says:

Did you register at https://developer.nvidia.com/vrworks as suggested?

I did register a long time ago. In the blog they say it is going to be ready at the end of the year - dec 2016. any news?
AMD already released the first beta for a similar sdk on December 2016. I hope nvidia launches soon :)

i’m also looking for this SDK let me know if you have any luck. Thanks
