+ Layer based image editing, an industry standard.
+ Make new images and layers using your built-in iSight.
+ Easy image and canvas resizing, just by changing the size of your window.
+ Take advantage of every pixel of your monitor with full screen image editing.
+ Tablet sensitive for pressure strokes and using the tablet's eraser.
+ Vector shape and text layers.
+ Freeform, elliptical, rectangular, and magic wand selections.
+ Create and apply custom text styles.
+ Control opacity and blending modes for each layer.
+ Write plugins using the Python scripting language, as well as in Objective-C.
+ GPU powered. The same graphics card that makes your gaming experience smooth, helps Acorn fly through the toughest of graphics operations.
+ You can now drag multiple images from the Finder into the canvas or layers list and they will all be added as new layers.
+ Change: No longer drawing handles when creating or modifying shape layer graphics.
+ Better command-click selection behavior with overlapping shapes on shape layers.
+ Added an alert when trying to delete from a bitmap layer when you have a layer filter enabled which is not set to preserver transparency (such as the Render Clouds filter). Otherwise you'd hit delete and nothing would seem to happen.
+ Added warnings when trying to use the draw / erase / brush / instant alpha tools on multiple layers at once.
+ Tiny speed improvements with Flood Fill (Mr. Paint Bucket), Instant Alpha, and the Magic Wand.
+ Better rounding in the window status bar for canvas sizes displaying in centimeters and inches.
+ Acorn is a little smarter about sizing the Layer Filters palette when the Window > Gather Palettes menu item is used.
+ Fixed a bug with the destination in layer blend mode.
+ Filter fixes for Mavericks.
+ Fix: Fixed a bug where the corner radius of a shape would get reset.
+ Fix: The Quick Config popover wasn't showing up if your cursor wasn't in the canvas. Now it does.
+ Fix: The cursor location in the canvas wasn't being updated when making gradients or drawing out shapes. This bug has now been squashed.'
+ Fix: When scaling an image with shapes that had gradients on them, the gradients weren't being scaled along. This is now fixed.
+ Fix: The freehand selection tool no longer shows a dashed line when making selections on shape layers.
+ Fixed a bug where the marching ants selection marker guy wouldn't draw correctly at oddball zoom levels like 57%.
+ Fixed a bug where duplicating a layer by dropping it on the + button in the palette wouldn't select it right away. You can also duplicate a layer by dragging it from the layers list onto the + button in the palette if you didn't know that already.
+ Fixed a bug where drawing with the pencil tool and then holding the shift key to draw a straight line from the last point wouldn't work.
+ Fixed a bug where using the Bump Distortion Linear filter would cause redraw problems.
+ Fixed a the shading of the 1024px version of the Acorn icon.
+ Fixed a bug where the shape height field was not updating correctly on Mavericks.
+ Fixed a bug where making multiple images in a row would cause the dimensions of the new image window to increase each time if you had the units set to centimeters.
+ Fixed a bug where deleting the very first element in a bezier path would sometimes also delete the last one.
+ Fixed a bug where sometimes the Web Export preview window wouldn't center images.
+ Fixed a bug where the selection bounds in the palette wouldn't update correctly when switching open images.
+ Fixed a bug where the background blur filter didn't look correct at zoom levels less than 100%
