ImprovementsSection of the release
The /diff command's fullscreen behavior — "Toggle the diff panel showing uncommitted changes" with immediate fullscreen mode — is now active by default for everyone. It is controlled by a kill-switch flag, tengu_jazzy_ripple, that must be explicitly turned on to suppress the new behavior.
Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.
