Coda 2.5 is essentially complete. But, we’re still encountering sandboxing challenges. So, in the interest of finally getting Coda 2.5 out the door and in the hands of you, our very eager and patient customers, we’ve decided it’s time to move on—for now.
In short: Coda 2.5 will not be sandboxed, and therefore will not be available in the Mac App Store.
It’s unfortunate, but the folks at Panic aren’t the only ones running into these issues.
