Bitcoin Core 32 can stall multisig signing on older nodes as fix slips to next patch

Bitcoin Core 32.0’s graphical wallet can interrupt co-signing with older Core wallets by creating transaction files those versions cannot import, according to a user report . The compatibility issue has moved to the 32.1 milestone, while a proposed GUI fix remains open. In the Oct. 14 report, user mjdietzx described an unsupported-version decoding error when loading a file created by the new graphical wallet into pre-32 Core. The GUI offered no version selector. That can stop a workflow in which a newer Core wallet prepares a transaction and an older Core wallet supplies another signature.
