- [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.
