Bitcoin Core 32.1 introduces network, privacy and interface changes, while versions 31.2 and 30.4 provide maintenance updates. Version 32.0 was tagged but was ultimately not announced or released because of issues discovered late in the process. Bitcoin Core 32.1 includes a fix for a possible IP address exposure in a specific private-broadcast configuration and changes to outgoing transaction relay limits. Some deprecated interface fields have also been removed or modified, which may cause failures in applications connected to the node even when synchronization succeeds. Operators should therefore verify integrations, network use, service recovery and wallet format compatibility before upgrading or rolling back.
