Hi dao1 - do you have a particular question in mind?

The impact of this proposal is the continued deployment of incremental changes. As mentioned in the proposal, there are two features, but they don’t have an external impact for most users. One is allowing further development of chain key cryptography, and the other is making the registry safer.

Our standard is to release changes with regularity and keep our mainline development in an always-deployable state.
