What probably matters to youSection of the release
What
Buttons built with the toolkit used for panes now accept a role setting. The only allowed value is "dismiss". Any other value causes an error, and the error that lists a button's valid settings now includes it.
Why
People who build pane or plugin screens can mark a button as the one that closes or dismisses the pane.
