HTTP/3 is the coming new HTTP version that uses QUIC for transport! That’s an interesting development to follow, HTTP(S) over UDP and how that’ll go with (small) office and home equipment hardware, IOT, middleware

The protocol that’s been called HTTP-over-QUIC for quite some time has now changed name and will officially become HTTP/3. This was triggered by this original suggestion by Mark Nottingham.
