Bitcoin Core 32 Nears Final Release with Fee Estimation and Performance Improvements

Bitcoin Core 32 is nearing its final release after developers tagged v32.0rc1 on September 14. This new version focuses on node software behavior, wallet interfaces, fee calculation, networking, and performance.

One of the key features in Bitcoin Core 32 is a new fee estimator that combines block history with current mempool conditions to provide more accurate estimates. The new estimator produces both economical and conservative estimates based on current pending transaction conditions and can reject the estimate when the mempool appears too sparse or unhealthy.

The software also includes improvements to block validation, which now prefetches previous outputs across eight worker threads by default, reducing disk waits. Additionally, a security flaw that could allow authenticated users to execute commands on affected non-Windows node systems has been fixed.
