What probably matters to youSection of the release
What
Plugins that draw their own screens through ui.render can now use a Progress element. It works on mobile only.
The descriptions of the keyboard shortcuts for moving between, resizing and closing plugin areas now say "plugin panel" instead of "plugin pane". This covers pane:grow, pane:shrink, pane:close, pane:next and pane:previous.
Why
Plugins on mobile have a way to show progress, and the shortcut descriptions use the word "panel".
