Hi,
I want to know if it is possible that the *initial_salt *is changed for a
version without changing the version field.

>From the data below, that is NOT the case and everytime the salt is
changed, the version is also changed.

https://datatracker.ietf.org/doc/html/draft-ietf-quic-tls-29
Version = 0xff00001d
initial_salt = 0xafbfec289993d24c9e9786f19c6111e04390a899

https://datatracker.ietf.org/doc/html/rfc9001
Version = 0x00000001
initial_salt = 0x38762cf7f55934b34d179ae6a4c80cadccbb7f0a

https://datatracker.ietf.org/doc/draft-ietf-quic-v2/07/
Version = 0x709a50c4
initial_salt = 0xa707c203a59b47184a1d62ca570406ea7ae3e5d3

https://datatracker.ietf.org/doc/draft-ietf-quic-v2/08/
Version = 0x6b3343cf
initial_salt = 0x0dede3def700a6db819381be6e269dcbf9bd2ed9

https://datatracker.ietf.org/doc/rfc9369/
Version = 0x6b3343cf
initial_salt = 0x0dede3def700a6db819381be6e269dcbf9bd2ed9
