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

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.
