 ### IMPROVEMENTS:
 
+- [mempool] [\#4083](https://github.com/tendermint/tendermint/pull/4083) Added TxInfo parameter to CheckTx(), and removed CheckTxWithInfo() (@erikgrinaker)
 - [mempool] [\#4057](https://github.com/tendermint/tendermint/issues/4057) Include peer ID when logging rejected txns (@erikgrinaker)
 - [tools] [\#4023](https://github.com/tendermint/tendermint/issues/4023) Improved `tm-monitor` formatting of start time and avg tx throughput (@erikgrinaker)
 - [libs/pubsub] [\#4070](https://github.com/tendermint/tendermint/pull/4070) No longer panic in `Query#(Matches|Conditions)` preferring to return an error instead.
