* New Synth Fill tool, which you can use to brush away unwanted objects in your photos.
* New Repair tool, which you can use to spot heal and touch up photos. It works by looking at the pixels around the area and with the magic of pattern matching, fills in a nice little patch for you.
You can now resize multiple selected bitmap layers at once, even with a selection.
* New Expand Selection option in the Selection palette, which lets you non-destructively expand the current selection by a set number of pixels. (Finally.)
* A new Temperature and Tint filter, which will help color correct overly warm or cool photos.
* A new High Pass filter, which keeps the edge details of your image and flattens everything else to gray. Useful for sharpening when blended with the original using Overlay.
* A new Edge Stroke filter, which adds a colored stroke around the transparent edges of your image.
* A new Color Overlay filter, which adds a colored overlay on top of your layer, with opacity and blend mode settings.
* When opening up a SVG file, you are now given options to set the DPI, width, and height of the resulting image (defaulting of course to what it would be if natively read at 72dpi). This new import window also gives you the option to rasterize the SVG file right away, which will use WebKit to render the SVG instead of converting it into native Acorn shape layer objects.
# Other
* Photoshop image import improvements: Support for reading 16 bit per channel PSD files, grayscale PSDs, and the Color Overlay layer effect.
* Various SVG importing and exporting improvements, including bitmap layers being written out to SVG files.
* When exporting as SVG, layer names are now preserved with the id attribute in the layer’s group tag.
* There’s a new menu item under the Help menu named What’s New in Acorn that loads up the latest release notes for you. It’ll automatically show once if you’re using the App Store version of Acorn. This also replaces the “Show Release Notes” menu item which would open a the notes in a browser window.
* The Flood Fill (paint bucket / color fill) tool has a new blend mode: “Copy (Opaque Only)”, which works like the Copy blend mode, but won’t replace all the pixels in your layer, just the ones that are being filled.
* The Paste and Match Style menu item is no longer hidden behind an option key. And you can now use it to make new Shape Layers if you have text on the clipboard.
* Moved the option for JPEG 2000 down the list in the Export window, as Apple depreciated it a while back (though it still works for now!).
* New Action Bar action “Disable All Snapping” which will turn off all snapping options for the open image. Also, did you know that ⌘⇧⌥; works as a toggle disable all snapping as well? So if you want it all off for a little while, that’s a nice shortcut to remember.
# 8.7.1 Fixes and Stuff:
* When exporting, hitting Cancel (or Escape or ⌘.) will cancel any background encoding operations if there is one going on. Otherwise it’ll close the window (previously it would close the window right away).
* Tweaks to how the export window remembers its previous settings.
* Added tooltips to the various scaling options in the image resize sheet.
* Fixed an issue where scaling text via handles with the Shift key down could cause weird font sizes.
* Fixed some printing regressions.
* Fixed an issue where previously selected arrow styles are not remembered between restarts of Acorn.
* Fixed an issue where the Synth Fill brush might not work on larger images.
* General stability improvements.
If you like Acorn, we’d love it if you could take a moment and give it a nice review. It helps Acorn get noticed, which helps everyone in the long run.
