The Pixelmator Team has released version 3.2 (nicknamed Sandstone) of its eponymous image-editing app with a revamped Repair Tool that should make it easier to fix imperfections and remove unwanted objects from your images (here’s a video sample of the Repair Tool in action, uploaded by Pixelmator). According to this blog post, the new Repair Tool comes with three repair algorithm options (Quick, Standard, and Advanced), which also use a quarter the memory of the previous version. Pixelmator 3.2 also adds support for 16 bits per channel, the capability to lock layers, and a Convert Selection into Shape feature. Additionally, the release makes numerous fixes and improvements, including a Color Depth dialog that can convert images to 16 bits or 8 bits per channel, a fix for ensuring the Info Bar updates after restoring an image to its previous version, and improved performance of the Stroke and Fill layer styles. Pixelmator 3.2 now requires OS X 10.9.1 Mavericks or later. ($29.99 new from the Mac App Store, free update, 35.7 MB, release notes, 10.9.1+)
