+* A bug that allowed fees to be up to 100% of the payment amount was fixed by
+  [introducing a more sane default

+  `--fee_limit` or `--fee_limit_percent` flags on the `lncli payinvoice`,
+  `lncli sendpayment` and `lncli queryroutes` commands. Users of the gRPC or
+  REST API should set the `fee_limit` field on the corresponding calls
+  (`SendPayment`, `SendPaymentSync`, `QueryRoutes`).
