Bitcoin Core releases version 31.0, improving Mempool logic.

Bitcoin Core has released version 31.0. This update primarily improves the Mempool (transaction pool) logic, allowing nodes to more accurately determine the overall value of a group of related transactions and decide whether to retain, forward, or package them. The impact on ordinary transfer users is minimal, but users using RBF, CPFP, Lightning Network, complex wallets, or server-side wallets may experience changes in transaction acceptance/rejection behavior. The update also enhances the private broadcast function, supporting the broadcast of sendrawtransactions via Tor/I2P, where the recipient cannot know the IP address and geographical location of the transaction initiator.
