I think it makes sense to have a dedicated page like this that lists any protocol changes that we do. But I think the current structure doesn't make much sense anymore. I expect no-one to upgrade a client from protocol 2.0 anymore. So I'd replace this page with a new one with the following structure
# Summary of protocol changes over time
## Protocol changes in version 3.2
- Longer cancel key messages
## Protocol changes to 3.0 without protocol version bump
- NegotiateProtocolVersion in 9.? - Direct SSL negotiation in PG17
Agreed that nobody upgrades a client from 2.0 but is there value in keeping the history ?
Perhaps another section which would be "Changes in 3.x" ?
