Cosmos SDK v0.45.9 Release Notes

This is a security release for the Dragonberry security advisory.
Please upgrade ASAP.

Chains must add the following to their go.mod for the application:

replace github.com/confio/ics23/go => github.com/cosmos/cosmos-sdk/ics23/go v0.8.0

Next to this, we have also included a few minor bugfixes.
