The release notes for 3.2 f say: Debugger: Attaching the script debugger to (and detaching from) Unity and debugging-enabled players is now possible.
Ok, so how? I'm not seeing any menu item for it, wouldn't that be nice?
I tried 'Sync Mono Development' but when that loaded, I hit 'Debug' and it told me this was too old and I should install a new one. I just installed an hour ago.
