The development of Bitcoin Core version 32 began with a scheduled feature freeze on August 20, 2026. At that stage, the project reported 82% completion of the v32 milestone, with developers shifting focus from new features to bug fixes in preparation for an October release.

By mid-September, the software entered its final testing phase following the release of the first candidate, v32.0rc1, on September 14. This update does not alter consensus rules but introduces technical changes to the RPC interface and transaction handling, specifically the adoption of the PSBTv2 format. 

Other technical improvements include a dual fee estimation system, enhanced database transaction lookup performance, and a new HTTP server. Developers also utilized an audit with Moonshot AI’s Kimi K3 model to resolve a memory exhaustion issue. The official release of v32.0 is targeted for October 10.
