Is there support for http2 on the roadmap ?

I am planning to implement the new APNs Provider API (apple push notification service) that is based on http2.

Definitely on the roadmap and there is even a working branch:
https://github.com/rejectedsoftware/vibe.d/tree/http2-botan-cleanup

It's currently slightly out of date due to a number of changes in the
HTTP code on master. The big issue is that it touches a lot of the
HTTP/1.1 logic. I'm therefore reluctant to merge everything at once, and
a meaningful review of the changes is extremely involved.

So what I'm leaning towards now is to re-integrate the changes from that
branch manually into a new separate vibe-http package (separate
repository, which some internal structural changes to get better
performance). This has a certain risk to introduce bugs, but that new
package would coexist with the old module for a while before being
declared as a stable successor module.
