Bitcoin Core Update Risks Temporary Disruptions Across Popular Apps

A new Bitcoin Core update is set to change default wallet protocols, potentially causing temporary disruptions across popular apps. The update, tagged as v32.0rc1, compresses checks across PSBTs, fee estimation, HTTP clients, indexes, and private broadcast.

The changes will see four RPCs defaulting to PSBTv2, requiring compatibility checks across wallet parsers and signers. This may cause issues for teams that create, convert, or fee-bump PSBTs.

Fee handling also requires failure-path coverage, as the combined estimate of fees can error if either component fails.
