 * (apps/27-interchain-accounts) [\#2290](https://github.com/cosmos/ibc-go/pull/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) [\#2248](https://github.com/cosmos/ibc-go/pull/2248) Adding call to underlying app in `OnChanCloseConfirm` callback of the controller submodule and adding relevant unit tests.
 * (apps/27-interchain-accounts) [\#2251](https://github.com/cosmos/ibc-go/pull/2251) Adding `msgServer` struct to controller submodule that embeds the `Keeper` struct.    
+* (light-clients/06-solomachine) Moving 'verifyMisbehaviour' function from update.go to misbehaviour_handle.go.
