 * [\#1226](https://github.com/cosmos/relayer/pull/1226) Avoid invalid Bech32 prefix error in parallel tests when sdk Config get overwritten by each other in single process.
 * [\#1231](https://github.com/cosmos/relayer/pull/1231) Reduce get bech32 prefix when get signer.
+* [\#1302](https://github.com/cosmos/relayer/pull/1302) Avoid packet get relayed when estimated gas is higher than max gas.
+* [\#1303](https://github.com/cosmos/relayer/pull/1303) Add missing max gas amount on txf to avoid estimate less gas when simualte runTx.
