 ### Improvements
 
+<<<<<<< HEAD
+=======
+* (transfer) [\#1342](https://github.com/cosmos/ibc-go/pull/1342) `DenomTrace` grpc now takes in either an `ibc denom` or a `hash` instead of only accepting a `hash`.
+* (modules/core/keeper) [\#1284](https://github.com/cosmos/ibc-go/pull/1284) Add sanity check for the keepers passed into `ibckeeper.NewKeeper`. `ibckeeper.NewKeeper` now panics if any of the keepers passed in is empty.
+* (middleware) [\#1022](https://github.com/cosmos/ibc-go/pull/1022) Add `GetAppVersion` to the ICS4Wrapper interface. This function should be used by IBC applications to obtain their own version since the version set in the channel structure may be wrapped many times by middleware. 
+>>>>>>> 23e7e7d (chore: improve DenomTrace grpc (#1342))
 * (modules/core/04-channel) [\#1160](https://github.com/cosmos/ibc-go/pull/1160) Improve `uint64 -> string` performance in `Logger`.
 * (modules/core/keeper) [\#1284](https://github.com/cosmos/ibc-go/pull/1284) Add sanity check for the keepers passed into `ibckeeper.NewKeeper`. `ibckeeper.NewKeeper` now panics if any of the keepers passed in is empty.
 * (transfer) [\#1414](https://github.com/cosmos/ibc-go/pull/1414) Emitting Sender address from `fungible_token_packet` events in `OnRecvPacket` and `OnAcknowledgementPacket`.

+# Migrating from ibc-go v3 to v4
+
+This document is intended to highlight significant changes which may require more information than presented in the CHANGELOG.
+Any changes that must be done by a user of ibc-go should be documented here.
+
+There are four sections based on the four potential user groups of this document:
+- Chains
+- IBC Apps
+- Relayers
+- IBC Light Clients
+
+**Note:** ibc-go supports golang semantic versioning and therefore all imports must be updated to bump the version number on major releases.
+```go
+github.com/cosmos/ibc-go/v3 -> github.com/cosmos/ibc-go/v4
+```
+
+No genesis or in-place migrations required when upgrading from v1 or v2 of ibc-go.
+
+## Chains
+
+### IS04 - Channel 
+
+The `WriteAcknowledgement` API now takes the `exported.Acknowledgement` type instead of passing in the acknowledgement byte array directly. 
+This is an API breaking change and as such IBC application developers will have to update any calls to `WriteAcknowledgement`. 
+
+The `OnChanOpenInit` application callback has been modified.
+The return signature now includes the application version as detailed in the latest IBC [spec changes](https://github.com/cosmos/ibc/pull/629).
+
+## Relayers
+
+When using the `DenomTrace` gRPC, the full IBC denomination with the `ibc/` prefix may now be passed in.
