v3.0.0-rc1

This release includes v1 of the Interchain Accounts application module. 🍾

This is the first major feature addition since the v1.0.0 release of ibc-go. 👏

Kudos to everyone that has contributed to this feature on protocol design, implementation, testing and auditing. 🙏

Shout-out to the team at Chainapsis for the brilliant work that kick-started everything. 🌟

And last but not least, we want to thank @seantking for leading the efforts to bring all this to fruition.🥇

At a high level, when comparing to v3.0.0-rc0 this release:

• bumps the version of ics23/go to v0.7 .

• adds a function `InitModule` to the interchain accounts `AppModule`. This function should be called within the upgrade handler when adding the interchain accounts module to a chain. It should be called in place of `InitGenesis` (set the consensus version in the version map).

• adds support for base denoms with slashes.

• classifies client states without consensus states as expired.

Please see the CHANGELOG for the full set of changes included in this release.

Please read the migration doc , which provides information on updating from v2 to v3.
