• #860 Fix EIP-712 signature verification to use configured EVM chain ID instead of parsing cosmos chain ID string and replace legacytx.StdSignBytes with the aminojson sign mode handler.
• #794 Fix mempool.max-txs flag not using desired default of 0
• #748 Fix DynamicFeeChecker in Cosmos ante handler to respect NoBaseFee feemarkets’ parameter.
