Pixelmator 2.2.2 Quick Update
We have put together a small update squashing some minor flaws in current version of Pixelmator. The update is now available to download, and comes with improved Pixelmator file format compression when saving to iCloud, as well as other tiny improvements and bug fixes (you can check the full list here). The update is so small that I think it should be called a supplemental update, although the number 2.2.2 is nice too.
Enjoy, and stay tuned for bigger news to come!
