🚀 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:

• 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.
