UPDATES

15th March 2022: This release is NOT recommended since it contains a security vulnerability in the transfer application. Please use version >= 2.1.0.

Please read the migration doc, which provides information on updating from v1 to v2.

Dependencies

  • #489 Bump Tendermint to v0.34.14
  • #503 Bump SDK version to v0.44.3

API Breaking

  • (core) #227 Remove sdk.Result from application callbacks.
  • (transfer) #350 Change FungibleTokenPacketData to use a string for the Amount field. This enables token transfers with amounts previously restricted by uint64. Up to the maximum uint256 value is supported.

Features

  • #384 Added NegotiateAppVersion method to IBCModule interface supported by a gRPC query service in 05-port. This provides routing of requests to the desired application module callback, which in turn performs application version negotiation.

To learn more about ibc-go versioning, please read our RELEASES.md.

IMPORTANT: Please read the migration guides for any versions of ibc-go that you might be going through when upgrading to this version. For example: if you upgrade from the IBC module contained in the Cosmos SDK 0.42.0 to SDK v0.44.3 and ibc-go v2.0.0, please follow the migration from SDK 0.41.x or 0.42.x to the IBC module in the ibc-go repository based on the SDK v0.44.x AND the migration from ibc-go v1 to v2.
