I never actually used Iris (my image editor of choice is still Pixelmator), but the one-window image editor released a few years ago certainly had its share of fans. Unfortunately, those fans may be disappointed to hear that Iris' developer, Nolobe, has suspended development on the app. Nolobe's principal Matthew Drayton says that back in 2007, when Iris started development, there were no cheap yet quality image editors, and nowadays, the app has simply become a "me too" app. He doesn't want to do that, so he's out.
Fortunately, however, Iris owners aren't completely left in the lurch -- Drayton highly recommends Acorn, and anyone who currently owns Iris will be able to get a free upgrade to that app. Sad to see that a quality image editor is calling it quits, but the reasons seem legit and the transition should go smoothly. If you own Iris, watch your email for directions on how to upgrade, or contact Nolobe yourself.
It's not all glum news from Nolobe: the company has a great deal going now for its flagship FTP client, Interarchy. Commemorating the two-year anniversary of an office-gutting fire (well, maybe it is kinda glum, now that we think about it), the Interarchy Fire Sale offers a steep discount on the app for the next week, along with discount codes for several other leading indie apps (including Acorn). The $19.95 Interarchy 9 licenses are valid for free upgrades to version 10 (now in beta), which adds up to a savings of almost $70.
