🚀 Highlights

This releases adds several features made possible by the upgrade to Cosmos SDK v0.47:

• The IBC rate limit module prevents massive inflows or outflows of IBC tokens in a short time frame to add an extra layer of protection on IBC transfers.
• The ICA controller sub-module enables Hub users to perform actions on other chains using their Hub accounts.
• The IBC fee middleware enables creating IBC channels with in-protocol incentivization for relayers.

This release also bumps ICS to v4.1.0-lsm, which introduces ICS epochs to reduce the relaying cost for ICS.
