I’m sorry to announce that we’ve spotted a slight problem with the Mac App store version of Neu 1.0.3 - only two of the preference panels load successfully.
This problem doesn’t affect the version of Neu that you download from here, so if you’ve bought Neu directly from us, you can safely update.
However, if you’ve bought from the Mac App store, we’d ask you to hold of updating until we can work out what’s going on and submit a fix.
If it’s too late and you’ve already updated, Neu should continue to work ok, you simply won’t be able to adjust certain preferences. Which is obviously not ideal, so we’ll get a fix out to you as soon as we possibly can.
