Bitcoin Core has released its 31st major update. This time, the focus is on improving the Mempool (transaction pool). Nodes will now be better at judging whether 'a group of related transactions as a whole is worth keeping, forwarding, or including in a block.' Regular users making simple transfers might not notice much difference, but those using RBF, CPFP, Lightning Network, complex wallets, or server-side wallets may encounter changes in transaction acceptance/rejection behavior compared to the old version. Additionally, private broadcasting has been enhanced, allowing sendrawtransaction to be broadcast via Tor/I2P. This means the recipient won’t know the sender’s IP address or geographic location. If the same sender initiates two unrelated transactions, it will also be harder to link them, as each transaction is broadcast using a separate connection.
