I released a small bug fix update to Clipstart today, version 1.4.2, to fix an issue with YouTube uploads when using your Gmail address sign-in instead of the YouTube account username. This version should also show up in the Mac App Store after it goes through Apple’s approval process. You can see the full release notes for recent bug fixes here.
As I said earlier this year, there will only be a couple more releases of Clipstart in the Mac App Store. My current plan is to switch completely over to direct-only sales with version 1.5. The new versions run without prompting for registration if you’ve already purchased and run a copy from the Mac App Store.
