user5406: Bitcoin ABC is fully compatible to Bitcoin up to the fork. Does that mean that an unsynchronized Bitcoin ABC node sends Bitcoin transactions instead of Bitcoin Cash?

user38618: The latest version of Bitcoin ABC that is released before UAHF happened, sends Bitcoin-style transactions if it is not synced.
Proof: https://github.com/Bitcoin-ABC/bitcoin-abc/commit/fda9dab6a9fba4a95aa2d9620f28b787efccf748
The current latest version always sends Bitcoin Cash transactions.
