 ### API Breaking
 
+* (testing) [\#1003](https://github.com/cosmos/ibc-go/pull/1003) `CreateTMClientHeader` takes an additional `nextVals *tmtypes.ValidatorSet` as an argument
 * (testing) [\#939](https://github.com/cosmos/ibc-go/pull/939) Support custom power reduction for testing.
 * (modules/core/05-port) [\#1086](https://github.com/cosmos/ibc-go/pull/1086) Added `counterpartyChannelID` argument to IBCModule.OnChanOpenAck
 * (channel) [\#848](https://github.com/cosmos/ibc-go/pull/848) Added `ChannelId` to MsgChannelOpenInitResponse

 ### Improvements
 
 * (interchain-accounts) [\#1037](https://github.com/cosmos/ibc-go/pull/1037) Add a function `InitModule` to the interchain accounts `AppModule`. This function should be called within the upgrade handler when adding the interchain accounts module to a chain. It should be called in place of InitGenesis (set the consensus version in the version map).
+* (testing) [\#1003](https://github.com/cosmos/ibc-go/pull/1003) Testing chain's `Signer` fields has changed from `[]tmtypes.PrivValidator` to `map[string]tmtypes.PrivValidator` to accomodate valset updates changing the order of the ValidatorSet.
+* (testing) [\#1003](https://github.com/cosmos/ibc-go/pull/1003) `SignAndDeliver` will now just deliver the transaction without creating and committing a block. Thus, it requires that `BeginBlock` MUST be called before `SignAndDeliver`
+* (testing) [\#1003](https://github.com/cosmos/ibc-go/pull/1003) `NextBlock` will now call `EndBlock` and `Commit` internally and apply validator updates to the `NextVals` of `TestChain` and the `NextValsHash` of the current header. Test writers can now make changes to validator set and have them reflected in the `TestChain` and handled appropriately in `UpdateClient`
 * (testing) [\#942](https://github.com/cosmos/ibc-go/pull/942) `NewTestChain` will create 4 validators in validator set by default. A new constructor function `NewTestChainWithValSet` is provided for test writers who want custom control over the validator set of test chains.
 * (testing) [\#904](https://github.com/cosmos/ibc-go/pull/904) Add `ParsePacketFromEvents` function to the testing package. Useful when sending/relaying packets via the testing package.
 * (testing) [\#893](https://github.com/cosmos/ibc-go/pull/893) Support custom private keys for testing.
