+Updated RPCs
+------------
+
+- `getbalances` now includes a `nonmempool` field under `mine`, reporting
+  the net balance of wallet transactions that are not in the mempool (e.g.
+  due to too low a feerate, too many unconfirmed ancestors, or a too-large
+  `OP_RETURN` output). This value is always negative, and is typically an
+  over-estimate since it accounts for coins being spent but not for change
+  outputs returning to the wallet (which are also outside the mempool).
+  Without this field, funds involved in non-mempool transactions could
+  appear to go missing from the wallet balance. (#33671)
