UPDATES

• 27th October 2022: This release is NOT recommended since it uses a version of the Cosmos SDK impacted by the dragonberry security advisory. Please use version >= 3.3.1.

This release includes a fix for a security vulnerability identified in the ICS27 host submodule. User funds in accounts and staking delegations are NOT at risk.

This release uses Cosmos SDK v0.45.8 and Tendermint v0.34.21. For more information, see Cosmos SDK v0.45.8 Release Notes and Tendermint v0.34.21 Changelog.

We present here the other changes in this release. Please see the v3.3.0 changelog for more information.

apps/27-interchain-accounts

• The InterchainAccount query RPC method and CLI query have been added to the controller submodule to allow end users the ability to inspect the interchain account address generated on the host chain.
• Nil checks have been added to ensure services are not registered for nil host or controller keepers.
