v2.3.1 — fix menu Quit in the settings screen
Patch: menu Quit (⌘Q) now works in the settings screen
Fixes a bug in v2.3.0: if you held Option to open the settings screen and then chose Quit from the menu (or pressed ⌘Q), nothing happened — the app stayed open. (You could still quit via the window's own Quit button.)
SDLApplication's terminate: only posted an SDL_QUIT event, which is consumed by the engine's event loop — but that loop isn't running while the settings window is up, so the event was dropped. It now exits cleanly when the engine hasn't started yet; normal in-game quit is unchanged.
Reported on the G3 (Panther); fix verified on the G4 (Tiger).
No other changes from v2.3.0 (in-engine sysreport + the Option-gated settings GUI). Universal binary: ppc750 / ppc7400 / ppc970 / x86_64. DMG content-verified byte-for-byte against source and smoke-tested on hardware.
