 * (apps/27-interchain-accounts) [\#5533](https://github.com/cosmos/ibc-go/pull/5533) ICA host sets the host connection ID on `OnChanOpenTry`, so that ICA controller implementations are not obliged to set the value on `OnChanOpenInit` if they are not able.
 * (core/02-client, core/03-connection, apps/27-interchain-accounts) [\#6256](https://github.com/cosmos/ibc-go/pull/6256) Add length checking of array fields in messages.
