What
Backdrop has been removed from the list of places a plugin may draw through ui.render. A screen now asks for it as the backdrop of Theme instead. The AbovePromptList spot is now described as internal to Claude Code.
Why
Plugin authors who drew at Backdrop directly need to go through a theme's backdrop instead, and should not rely on AbovePromptList.
