Bitcoin Core releases version 32.1 with privacy fixes

The Bitcoin Core project has released version 32.1, introducing several network, privacy, and interface updates. The release notes indicate that version 32.0 was tagged but never fully announced or released due to last-minute issues, making 32.1 the primary new major-version release.

Key technical updates include a fix for potential IP-address exposure in specific private-broadcast fallback configurations. The release also implements changes to outgoing transaction relay limits and introduces additional controls regarding private-broadcast queues.

Additionally, the update modifies certain defaults and removes previously deprecated fields from specific interfaces. Developers and operators of exchanges, wallets, or payment processors are advised to inspect their integrations, as changes in returned information or resource use could impact applications that rely on specific interface fields.
