### API Breaking

* (transfer) [\#1250](https://github.com/cosmos/ibc-go/pull/1250) Deprecate `GetTransferAccount` since the `transfer` module account is never used.
* (modules/29-fee)[\#1338](https://github.com/cosmos/ibc-go/pull/1338) Renaming `Result` field in `IncentivizedAcknowledgement` to `AppAcknowledgement`.
