Please read the migration doc which provides information on updating from the v0.40.x - v0.42.x SDK releases
This release bumps the SDK dependency to v0.43.0-rc2. This release also include one state machine breaking change:
- (core) #268 Perform a no-op on redundant relay messages. Previous behaviour returned an error. Now no state change will occur and no error will be returned.
And one improvement:
- (modules/core/ante) #235 Introduces a new IBC Antedecorator that will reject transactions that only contain redundant packet messages (and accompany UpdateClient msgs). This will prevent relayers from wasting fees by submitting messages for packets that have already been processed by previous relayer(s). The Antedecorator is only applied on CheckTx and RecheckTx and is therefore optional for each node.
The swagger files for the gRPC endpoints have also been generated.
If no issues are reported and the SDK finalizes v0.43 then this will be the final release v1.0.0
