Even though this a crucial bug update to fix problems in 1.6 it has been rejected on the Mac App Store after and already long review so expect more delays. The current reviewer must have been more strict because the previous versions all passed. If you need a newer version you can always contact us and we’ll send you a website version (with Sparkle auto-update) that you can use to the replace the Mac App Store version.
I said it once and I’ll say it again: don’t buy on the Mac App Store. Refunds are hard to get, updates can take weeks (even for critical bug fixes) and worst of all developers get paid 30% less which means less funds for future development.
