Under the hood
Plugin UI rendering adds support for a new 'Client' component type
What
The function that walks a plugin's UI render tree (used for both rendering and permission checks) now has a dedicated branch for a component of type Client, handling it before falling through to the generic children-recursion or the existing Button/Input/Select handling.
Why
This adds support for a new kind of UI component in plugin interfaces, though what a Client component represents or renders as isn't stated.
