Bitcoin Core v32.0rc1 update introduces wallet protocol changes, posing integration risks

Bitcoin Core v32.0rc1 has entered a testing phase ahead of its planned October 10 release. The update introduces changes to RPC interfaces and wallet protocols, including a shift to PSBTv2 for specific RPCs and the removal of deprecated fields. These modifications may cause compatibility issues for node operators and service providers. The release also features parallel prefetching of transaction outputs to improve block processing performance. Operators are advised to test the candidate in isolated environments to identify potential impacts on hardware performance and integration stability.
