-- [Bitcoin Core #19109][] Only allow getdata of recently announced invs FIXME:adamjonas
+- [Bitcoin Core #19109][] introduces further improvements to
+  [transaction-origin privacy][transaction origin wiki]. Building on
+  [Bitcoin Core #18861][bitcoin 18861 newsletter], this patch adds a
+  per-peer rolling bloom filter to track which transactions were recently
+  announced to the peer. When a peer requests a transaction, this upgrade
+  checks the filter before fulfilling the request and relaying the
+  transaction to prevent spy nodes from learning about the exact contents
+  of our mempool or the precise timing of when a transaction was received.
 
 - [Bitcoin Core #16525][] updates several RPCs to return transaction
   version numbers as unsigned integers rather than signed integers.
