### BREAKING CHANGES:

- CLI/RPC/Config

- Apps

- Go API

  - [abci] \#2127 ABCI / mempool: Add a "Recheck Tx" indicator. Breaks the ABCI
    client interface (`abcicli.Client`) to allow for supplying the ABCI
    `types.RequestCheckTx` and `types.RequestDeliverTx` structs, and lets the
    mempool indicate to the ABCI app whether a CheckTx request is a recheck or
    not.
