Upstream Http2 support

Hello. I wonder the Kong gateway supports Http/2 communication with upstream server.
When I set http2 ssl in proxy_listen configuration, client communicates with kong gateway by Http2, but not between kong gateway and upstream.

Other api gateway such as WSO2, it supports http/2 communication with upstream.

And I found same question here.

Thank you.

I’m curious about this too.
Exactly the same question I was trying to ask.
If http2 is not currently supported, I wonder if there are any plans to support it.
