🚀 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.

🚀 Highlights

The focus of this release is the upgrade of Cosmos SDK to v0.50 -- this release uses v0.50.9-lsm, a special Cosmos SDK branch with support for LSM. Consequently, it also upgrades the following dependencies:

• IBC to v8.4.0
• CometBFT to v0.38.9
• Interchain Security to v5.1.1
• Packet Forward Middleware to v8.0.2
• IBC Rate Limiting to v8.0.0
• Fee Market to v1.0.4
• CosmWasm/wasmd to v0.51.0

As a result of the IBC upgrade, this release will enable IBC channel upgrades, e.g., existing IBC channels can be upgraded to add relayer incentivization through IBC fees.
