This release bumps Interchain Security (ICS) to v6.4.0 which brings the following improvements to the provider module:

Add a priority list to the power shaping parameters. This enables consumer chains to further customize their validator set by setting a list of validators that will have priority regardless of their voting power.
Remove the governance proposal whitelisting from consumer chains. See this discussion for details on the motivation for this change.
Enable the chain ID of a consumer chain to be updated after creation, but before launch. As a result, it brings more flexibility to consumer chain deployment, especially to chains that are not yet sure about their final chain ID.
Enable querying the provider module for the genesis time for a consumer chain. As a result, consumer chains can set an accurate genesis time in the genesis file when bootstrapping their chain. See this issue for more details.
Enable consumer chains to have customizable slashing and jailing (as per ADR 020). As a result, consumer chain owners will be able to customize both the jailing period and slashing factor for different types of infractions. Note that the default params will maintain the current behavior, especially the no slashing for downtime.
Simplify the changeover from standalone to consumer chains. Basically, this feature enables consumer chains to reused the existing IBC connection to the provider (the one created as standalone chains). This simplifies the process as new clients no longer need to be created, which means the initial height initialization parameter is no longer needed.

This release also bumps the following dependencies:

Cosmos SDK to v0.50.11-lsm. This includes the changes introduced by Cosmos SDK v0.50.10 and v0.50.11, as well as fixes for issues identified by OtterSec and Zellic during their audit of LSM. Note that none of the identified issues are critical.
CometBFT to v0.38.15.
IBC to v8.5.2.
wasmd to v0.53.2.
