🚀 Highlights

This release bumps Interchain Security (ICS) to v6.3.0 which brings the following improvements:

• Enable consumer chains to use the memo field of the IBC transfer packets to tag ICS rewards with the consumer ID. As a result, consumer chains can send ICS rewards in any denomination and on any IBC channel. For example, a consumer chain could send USDC as ICS rewards.

• Enable each consumer chain to permissionlessly add up to three denoms that will be accepted as ICS rewards.

The release also distributes all the unaccounted known denoms from the consumer rewards pool via migration.
