There is a System Preference to re-enable Flash in QuickTime. For
those of you using Flash inside of jit.qt.movie, you will need to
enable this manually.
Don't know what this means, exactly -- either Apple is preparing to
remove Flash support from QuickTime entirely (instead using WebKit
for this), or they may finally update Flash support within QuickTime,
or? Speculation aside, just thought this should be known.
