🚀 Highlights

This is a major ICS release that brings a series of improvements to both provider and consumer chains.

• Remove the VSCMaturedPackets from the consumer module (as per ADR 018).
• Add a priority list to the power shaping parameters.
• Remove the governance proposal whitelisting from consumer chains.
• Enable the chain ID of a consumer chain to be updated after creation, but before launch.
• Enable querying the provider module for the genesis time for a consumer chain.
• Enable consumer chains to have customizable slashing and jailing (as per ADR 020).
• Simplify the changeover from standalone to consumer chains by reusing the existing IBC connection to the provider.

In addition to the above improvements, this release also adds interchain tests to ICS. This is an effort to simplify the testing framework and increase the confidence of ICS releases.

🚀 Highlights

This release introduces the following features:

• Permissionless (as described in ADR 019) enables users to permissionlessly launch opt-in consumer chains. Note that Top N consumer chains will still need to go through governance.
• Inactive Provider Validators (as described in ADR 017) enables validators from outside the provider's active validator set to validate on consumer chains.
• Removal of Unbonding Pausing (i.e., the provider-side changes of ADR 018) reduces the complexity of the ICS protocol and removes the dependency between the liveness of undelegation operations on the Cosmos Hub and the liveness of consumer chains.

In addition, it bumps the following dependencies:

• CometBFT to v0.38.11
• Cosmos SDK to v0.50.9
• IBC-Go to v8.5.0
