Bloomberg's Mark Gurman who has a good record on leaks, recently tweeted:
Improved audio mixing, slightly flatter interface tweaks. iMovie update too w/ support for the new MacBook Pro function row.
The tweet follows another from Richard Taylor who noticed that Apple was accidentally offering a FinalCutPro X 10.3 Trial Download despite that version not having been released.
The #FCPX trial now says 10.3 but doesn’t actually download the app yet.
It's possible that Apple plans to release the iMovie and Final Cut Pro X updates alongside new Macs. The company is rumored to be holding an event on October 27th to unveils its new computers.
