Bitcoin Core 32.1 introduces network, privacy and interface changes, while versions 31.2 and 30.4 provide maintenance updates for earlier branches. Version 32.0 was tagged but not fully announced or released because of last-minute issues, making 32.1 the relevant new major-version release. Changes include a fix for potential IP-address exposure under specific private-broadcast fallback conditions, revised outgoing transaction-relay limits, additional controls for private-broadcast queues, and interface changes that remove deprecated fields unless compatibility options are requested. The update does not alter Bitcoin's supply or transaction types, and it does not guarantee anonymity. Exchanges, wallets and payment processors should test how their applications interpret node responses and handle changed outputs. Operators should verify installed versions, network connections, dependent services and support status, while checking wallet-format compatibility before any rollback. Bitcoin holders who do not run nodes do not need to move their coins separately because of the release.
