Highlights 🌟
We present here a summary of the most relevant changes, please see the changelog for more details.
- In v0.4.1+ibc-go-v8.4-wasmvm-v2.0 we added a new
MerklePathtype and used it for thePathfield of theVerifyMembershipMsgandVerifyNonMembershipMsgstructs of the contract API. This change was API breaking for light contracts and it required a migration for existing contracts to correctly handle deserialization of theKeyPathfield (which had changed from[]stringto[][]byte). In this release we are making an extra change to explicitly break the contract API JSON message field name: thepathfield of the JSON-encodedVerifyMembershipMsgandVerifyNonMembershipMsgmessages has been renamed tomerkle_path, so that light client contracts would not silently unmarshal a key as a base64 encoded string value (and instead fail to unmarshal the message entirely).
All previous releases of the 08-wasm compatible with ibc-go v8.3 and wasmvm v2.0 have been retracted and we strongly recommend contract developers to update their JSON API message structure for the SudoMsg payloads VerifyMembershipMsg and VerifyNonMembershipMsg.
For chains on v8.4 or above in the v8 line that have not deployed a light client contract yet, we strongly recommend to upgrade to this release first and then deploy the updated contract. Otherwise, chains will need to migrate the contract later on.
