-quic-go is an implementation of the [QUIC](https://en.wikipedia.org/wiki/QUIC) protocol in Go. It implements the [IETF QUIC draft-29](https://tools.ietf.org/html/draft-ietf-quic-transport-29), [draft-32](https://tools.ietf.org/html/draft-ietf-quic-transport-32) and [draft-34](https://tools.ietf.org/html/draft-ietf-quic-transport-34).

-## Version compatibility
-
-Since quic-go is under active development, there's no guarantee that two builds of different commits are interoperable. The QUIC version used in the *master* branch is just a placeholder, and should not be considered stable.
-
-When using quic-go as a library, please always use a [tagged release](https://github.com/lucas-clemente/quic-go/releases). Only these releases use the official draft version numbers.
+quic-go is an implementation of the [QUIC protocol, RFC 9000](https://datatracker.ietf.org/doc/html/rfc9000) protocol in Go.
+In addition to RFC 9000, it currently implements the [IETF QUIC draft-29](https://tools.ietf.org/html/draft-ietf-quic-transport-29). Support for draft-29 will eventually be dropped, as it is phased out of the ecosystem.
