Bitcoin Core 32.0: Is Your Node Losing Support?

The first release candidate for Bitcoin Core 32.0 has been available since September 14, 2026. For you as the operator of your own node that means two things: the feature set of the coming major version is settled, and when it ships the 29 series drops out of the project's maintenance window. Anyone still running 29.x today will get no more security fixes after the planned date of October 10. The check takes two minutes; the update costs half an hour depending on your setup.

Our own count of reachable nodes worldwide, which we carried out for this article on the morning of September 15, shows how large the affected group is: roughly six in ten reachable Bitcoin nodes run a version that will no longer be a maintained one once 32.0 appears. The figures and the method are further down.

Bitcoin Core 32.0: what happened on September 14

Bitcoin Core is the reference software of the Bitcoin network. It checks blocks and transactions against the consensus rules, keeps its own copy of the blockchain and is therefore the foundation for anyone who does not leave their payments to somebody else's infrastructure. By its own schedule, the project publishes a major version roughly every six months.

On September 14, 2026, the tag v32.0rc1 appeared in the project's source repository, the first release candidate of the coming major version. The industry outlet TFTC puts this at 12:58 UTC and gives October 10, 2026 as the planned date for the final tag. That leaves a test window of around four weeks between candidate and release. For comparison: the most recently released major version, 31.0, dates from April 19, 2026 according to the project's lifecycle schedule, and the corresponding maintenance build 31.1 carries the date July 7, 2026 in the download directory.
