According to CoinDesk, Bitcoin Core 32.0 entered its final testing phase on September 14, with its official release scheduled for October 10. This update adds a transaction fee estimator based on real-time mempool status, enabling fee estimates to be lowered more quickly once network congestion subsides. It also enables multi-threaded parallel reading of transaction data to speed up node blockchain synchronization, defaulting to 8 threads. Security-wise, it resolves a wallet naming vulnerability on non-Windows systems since version 24.0 that allowed attackers to execute arbitrary commands on the node host via a specially crafted wallet name. Additionally, it patches an out-of-memory vulnerability in the newly added built-in web server; testing indicates that 16 unauthenticated connections can spike node memory usage from 46MB to roughly 3GB in approximately one minute. This update does not include any changes to Bitcoin's consensus rules.
