When a client receives a Version Negotiation packet, it MUST abandon the
current connection attempt. Version Negotiation packets are designed to allow
future versions of QUIC to negotiate the version in use between endpoints.
It is therefore expected for future versions of QUIC to change how
implementations which support multiple versions of QUIC react to Version
Negotiation packets when attempting to establish a connection of this version.
How to perform version negotiation is left as future work defined by future
versions of QUIC. In particular, that future work will need to ensure
robustness against version downgrade attacks {{version-downgrade}}.
