 * (feat) Bump [Interchain-Security](https://github.com/cosmos/interchain-security) [v1.1.0](https://github.com/cosmos/interchain-security/releases/tag/v1.1.0) provider module. See the [release notes](https://github.com/cosmos/interchain-security/releases/tag/v1.1.0) for details.
 * (feat) Add two more msg types `/ibc.core.channel.v1.MsgTimeout` and `/ibc.core.channel.v1.MsgTimeoutOnClose` to default `bypass-min-fee-msg-types`.
 * (feat) Change the bypassing gas usage criteria. Instead of requiring 200,000 gas per `bypass-min-fee-msg`, we will now allow a maximum total usage of 1,000,000 gas for all bypassed messages in a transaction. Note that all messages in the transaction must be the `bypass-min-fee-msg-types` for the bypass min fee to take effect, otherwise, fee payment will still apply.
