State Machine Breaking

Running a full node will encounter wrong app hash issue if it doesn't upgrade to this version prior to UpgradeHeight (48000). Instead of going through on-chain governance proposal by using UpgradeProposal, this upgrade mechanism is chosen as it is security hot fix that is better to be fixed as soon as it can and also it is directly related to governance proposal.
