Today we are happy to release the first Pixelmator 2.2.1 update. That may sound minor in numbers, but in our little Pixelmator world, it's a major one. We've done some radical improvements behind the scenes. One of them is a new Pixelmator file format. It's still the same file format you are used to, yet it now has a completely new architecture that takes advantage of the modern OS X technologies making your image editing even faster and more enjoyable.
Pixelmator documents now open twice as fast, iCloud saves are faster, and better Quick Look support allows users to preview documents without opening them. Background saves have been added, and a progress bar shows file status when opening and saving documents.
Quite a few improvements to effects have been added as well, designed to allow users to search, preview, and apply effects faster. Multiple effects have seen speed enhancements, and bug fixes that cause crashes have been applied. The full log of changes to Pixelmator 2.21 can be found on the company's support site.
