Mempool policy and package relay
The rules a node applies to unconfirmed transactions: what it relays, what it keeps, and how a child can pay for its parent. Package relay, version 3 transactions, ephemeral anchors and cluster mempool are the recent work, most of it driven by what Lightning needs to get a transaction confirmed in a hurry.
