Bitcoin Core 32 enters final testing with faster validation, fee changes and security fixes
The October update changes how nodes estimate transaction fees and process blocks, while fixing a wallet flaw that could let an authenticated user run commands on a node.
Bitcoin Core, the software used to run Bitcoin nodes, has moved its next major update into final testing with changes to transaction fees, block processing and the way wallets build transactions.
The first release candidate for Bitcoin Core 32.0 was tagged on Sept. 14, starting the final testing cycle before developers aim to release the finished version on Oct. 10, according to the project's release schedule.
Bitcoin Core lets a computer independently check transactions and blocks against Bitcoin's rules rather than relying on another service. Version 32 does not change those rules.
Applications can still request the older format, but services built directly around those Core commands will need to make sure they support version 2.
