From this commit: 257b51c37c5a: The HTTP/2 implementation

The HTTP/2 implementation (RFC 7240, 7241). The SPDY support is removed, as it’s incompatible with the new module.

nginx http/2.0 support has been implemented since 12 days ago, and the SPDY support was removed, the new version came after, nginx v1.9.5 was tagged since 39 hours ago, we can now download it from its download page, and there are also linux pre-built packages: http://nginx.org/en/linux_packages.html

For more info about http 2.0, see the links below:
