A clearing Bitcoin transaction queue can matter to the fee rate quoted by Bitcoin Core’s wallet, even while recent blocks still reflect busier conditions.

Core 32.1 adds an estimator that looks at the node’s mempool—the transactions waiting for confirmation. By default, the wallet uses the lower result from this and the existing block-based estimator, so its quote needn’t rely on recent blocks alone.

The change is in Core’s October 27 release notes. It gives the wallet another way to account for easing demand, not a promise that a cheaper transaction will confirm on time.
