- [abci] [\#2127](https://github.com/tendermint/tendermint/issues/2127)RequestCheckTx has a new field, `CheckTxType`, which can take values of `CheckTxType_New` and `CheckTxType_Recheck`, indicating whether this is a new tx being checked for the first time or whether this tx is being rechecked after a block commit. This allows applications to skip certain expensive operations, like signature checking, if they've already been done once. see [docs](https://github.com/tendermint/tendermint/blob/eddb433d7c082efbeaf8974413a36641519ee895/docs/spec/abci/apps.md#mempool-connection)
