Bitcoin Core 32 enters final testing

• Bitcoin Core 32.0 has entered final testing ahead of a planned October 10 release.
• The update adds faster block processing and a new fee estimator for changing network conditions.
• Developers have also fixed wallet command-execution and memory-exhaustion vulnerabilities before the stable release.

Bitcoin Core 32.0 has entered final testing, with developers targeting October 10 for the finished release.

The update will improve fee estimates, speed up block processing and make PSBT version 2 the default for several wallet commands.

Bitcoin Core 32.0 does not change Bitcoin (CRYPTO:BTC) consensus rules, which means nodes will continue validating transactions against the existing network rules.

The software adds a second fee estimator that examines unconfirmed transactions, allowing it to recommend lower fees when network congestion falls.

Nodes will also use eight processing threads by default to retrieve transaction data while validating blocks, reducing delays when catching up with the blockchain.

Developers have fixed a wallet vulnerability that could allow an authenticated user to trigger commands under certain configurations, alongside a memory-exhaustion flaw in the new web server.

Testing found that 16 unauthenticated REST connections could push one node from 46MB to about 3GB of memory in roughly one minute before the fix, while the same 90-second test used about 3MB afterwards.

At the time of reporting, Bitcoin price was $76,238.00.
