​

API Breaking

• (apps/27-interchain-accounts) #2607 SerializeCosmosTx now takes in a []proto.Message instead of []sdk.Msg.
• (apps/transfer) #2446 Remove SendTransfer function in favor of a private sendTransfer function. All IBC transfers must be initiated with MsgTransfer.
• (apps/29-fee) #2395 Remove param space from ics29 NewKeeper function. The field was unused.
• (apps/27-interchain-accounts) #2133 Generates genesis protos in a separate directory to avoid circular import errors. The protobuf package name has changed for the genesis types.
• (apps/27-interchain-accounts) #2638 Interchain accounts host and controller Keepers now expects a keeper which fulfills the expected exported.ScopedKeeper interface for the capability keeper.
• (transfer) #2638 Transfer Keeper now expects a keeper which fulfills the expected exported.ScopedKeeper interface for the capability keeper.
• (05-port) #2638 Port Keeper now expects a keeper which fulfills the expected exported.ScopedKeeper interface for the capability keeper.
• (04-channel) #2638 Channel Keeper now expects a keeper which fulfills the expected exported.ScopedKeeper interface for the capability keeper.
• (core/04-channel)#1703 Update SendPacket API to take in necessary arguments and construct rest of packet rather than taking in entire packet. The generated packet sequence is returned by the SendPacket function.
• (modules/apps/27-interchain-accounts) #2433 Renamed icatypes.PortPrefix to icatypes.ControllerPortPrefix & icatypes.PortID to icatypes.HostPortID
• (testing) #2567 Modify SendPacket API of Endpoint to match the API of SendPacket in 04-channel.

​

State Machine Breaking

• (apps/transfer) #2651 Introduce mustProtoMarshalJSON for ics20 packet data marshalling which will skip emission (marshalling) of the memo field if unpopulated (empty).
• (27-interchain-accounts) #2590 Removing port prefix requirement from the ICA host channel handshake
• (transfer) #2377 Adding sequence to MsgTransferResponse.
• (light-clients/07-tendermint) #2555 Forbid negative values for TrustingPeriod, UnbondingPeriod and MaxClockDrift (as specified in ICS-07).
• (core/04-channel) #2973 Write channel state before invoking app callbacks in ack and confirm channel handshake steps.

​

Improvements

• (apps/27-interchain-accounts) #2134 Adding upgrade handler to ICS27 controller submodule for migration of channel capabilities. This upgrade handler migrates ownership of channel capabilities from the underlying application to the ICS27 controller submodule.
• (apps/27-interchain-accounts) #2102 ICS27 controller middleware now supports a nil underlying application. This allows chains to make use of interchain accounts with existing auth mechanisms such as x/group and x/gov.
• (apps/27-interchain-accounts) #2157 Adding IsMiddlewareEnabled functionality to enforce calls to ICS27 msg server to not route to the underlying application.
• (apps/27-interchain-accounts) #2146 ICS27 controller now claims the channel capability passed via ibc core, and passes nil to the underlying app callback. The channel capability arg in SendTx is now ignored and looked up internally.
• (apps/27-interchain-accounts) #2177 Adding IsMiddlewareEnabled flag to interchain accounts ActiveChannel genesis type.
• (apps/27-interchain-accounts) #2140 Adding migration handler to ICS27 controller submodule to assert ownership of channel capabilities and set middleware enabled flag for existing channels. The ICS27 module consensus version has been bumped from 1 to 2.
• (core/04-channel) #2304 Adding GetAllChannelsWithPortPrefix function which filters channels based on a provided port prefix.
• (apps/27-interchain-accounts) #2248 Adding call to underlying app in OnChanCloseConfirm callback of the controller submodule and adding relevant unit tests.
• (apps/27-interchain-accounts) #2251 Adding msgServer struct to controller submodule that embeds the Keeper struct.
• (apps/27-interchain-accounts) #2290 Changed DefaultParams function in host submodule to allow all messages by default. Defined a constant named AllowAllHostMsgs for host module to keep wildcard ”*” string which allows all messages.
• (apps/27-interchain-accounts) #2297 Adding cli command to generate ICS27 packet data.
• (modules/core/keeper) #1728 Updated channel callback errors to include portID & channelID for better identification of errors.
• (testing) #2657 Carry ProposerAddress through committed blocks. Allow DefaultGenTxGas to be modified.
• (core/03-connection) #2745 Adding ConnectionParams grpc query and CLI to 03-connection.
• (apps/29-fee) #2786 Save gas by checking key existence with KVStore’s Has method.

​

Features

• (apps/27-interchain-accounts) #2147 Adding a SubmitTx gRPC endpoint for the ICS27 Controller module which allows owners of interchain accounts to submit transactions. This replaces the previously existing need for authentication modules to implement this standard functionality.
• (testing/simapp) #2190 Adding the new x/group cosmos-sdk module to simapp.
• (apps/transfer) #2595 Adding optional memo field to FungibleTokenPacketData and MsgTransfer.

​

Bug Fixes

• (modules/core/keeper) #2403 Added a function in keeper to cater for blank pointers.
• (apps/transfer) #2679 Check x/bank send enabled.
• (modules/core/keeper) #2745 Fix request wiring for UpgradedConsensusState in core query server.
