 ### API Breaking
 
+* (core/04-channel) [\#1792](https://github.com/cosmos/ibc-go/pull/1792) Remove `PreviousChannelID` from `NewMsgChannelOpenTry` arguments. `MsgChannelOpenTry.ValidateBasic()` returns error if the deprecated `PreviousChannelID` is not empty. 
 * (core/04-channel) [\#1418](https://github.com/cosmos/ibc-go/pull/1418) `NewPacketId` has been renamed to `NewPacketID` to comply with go linting rules.
 * (core/ante) [\#1418](https://github.com/cosmos/ibc-go/pull/1418) `AnteDecorator` has been renamed to `RedundancyDecorator` to comply with go linting rules and to give more clarity to the purpose of the Decorator.
 * (testing) [\#1418](https://github.com/cosmos/ibc-go/pull/1418) `MockIBCApp` has been renamed to `IBCApp` and `MockEmptyAcknowledgement` has been renamed to `EmptyAcknowledgement` to comply with go linting rules

 IBC Applications no longer need to account from already claimed capabilities in the `OnChanOpenTry` callback. The capability provided by core IBC must be able to be claimed with error. 
 `PreviousChannelId` in `MsgChannelOpenTry` has been deprecated and is no longer used by core IBC.
 
+`NewMsgChannelOpenTry` no longer takes in the `PreviousChannelId` as crossing hellos are no longer supported. A non-empty `PreviousChannelId` will fail basic validation for this message.

 ### ICS27 - Interchain Accounts
 
 The `RegisterInterchainAccount` API has been modified to include an additional `version` argument. This change has been made in order to support ICS29 fee middleware, for relayer incentivization of ICS27 packets.
