QUIC v0.2.0 and above are backwards incompatible with previous releases.
- Certificate/key generation has been altered to use ephemeral keys for the actual TLS handshake. This allows us to support arbitrary libp2p key types, even if the underlying TLS transport doesn’t support them.
- The underlying QUIC implementation has been updated to IETF QUIC draft-23.
This should be the last protocol breaking change before the transport is stabilized and enabled by default.
