+Wallet
+------
+
+* The `-zapwallettxes` startup option has been removed and its functionality removed from the wallet.
+  This option was originally intended to allow for the fee bumping of transactions that did not
+  signal RBF. This functionality has been superseded with the abandon transaction feature.
