Has there been any changes across core versions for the sendrawtransaction interface. I am trying to understand if upgrading the core version from say 12 to 15 needs a change in serialization. I'd also like to know if there are any versions across which such upgrade would fail.

sendrawtransaction takes transactions in the network serialization format. There is a new network serialization format for segwit transactions, so such transactions would be broadcast in one format for 0.12 and a different one in 0.15. If you are not making segwit transactions, then sendrawtransaction has not changed and you can use it in 0.15 as you did with 0.12.

@achow101 : Is it possible to know across which versions was the serialization changed in the past as well ? I assume this applies to all clients across the board ( Unlimtied , ABC etc). Thanks!– BoboCommented Oct 17, 2017 at 8:29

You can read the release notes of each release. The serialization format will only change when a fork happens (both hard or soft), but not every time there is a fork. The only time the serialization format has changed is between 0.12 and 0.13 with the introduction of Segwit. The format has only changed to allow a new format; the original format is still supported by all versions.– Ava Chow ♦Commented Oct 17, 2017 at 14:30
