New: New AppleScript property on bitmap layers to get and set the origin.
New: You can now delete a point on a bezier curve by selecting it and pressing the delete button.

Change: The menu item for the View ▸ Zoom tool has been renamed from "Zoom" to "Zoom Tool" so it doesn't confuse the system keyboard shortcuts with the menu item "Zoom" under the Window menu.
Change: Removed the CIColorMatrix from the filters sheet, since it only confused people with its complexity.

Fix: GIF wasn't an option in the "change file type" Automator action. This has now been corrected.
Fix: Fixed a bug where Acorn would crash when opening zero length .acorn files.
Fix: Fixed a bug where sometimes bad PSD files were written out because of empty layers.

Fix: Fixed a crasher when copying very very thin vector shapes.

Acorn 3.2 December 2, 2011

New: A new pref to ignore rotation gestures has been added.
New: Individual points in a bezier curve can now be selected and moved with the arrow keys.
New: Clicking on the gradient preview where you'd like a new color stop to show up will now add one.
New: Performance improvements with very large images.
New: The brush designer can now make brushes up to 400px in size.
New: The "Layer on Images in Acorn" Automator Action now has an opacity option when adding a new layer, making it easier to add watermarks to your images.

Change: If you add a new group layer using the tool palette + button (hold down the command key when pressing) Acorn will automatically being editing the layer name for you so you can give it a better name than just "Group"
Change: Text now has it's own setting for stroke with. Previously, setting the stroke from the shape palette would work on text, now it only works from the text palette.
Change: The hidden pref for adding a "Save A Copy As…" has been removed, since it caused problems on 10.7 with autosave and versions turned on. Since this operation was basically an export, we've assigned the keyboard shortcut for that option to the Export… menu item (cmd-option-s), so everything should be just as awesome as it has always been. However, make sure to let us know if this ruins your day.
Change: The system font palette (the one that comes up with cmd-t) no longer shows the text shadow widgets. To add a shadow to text, use the shadow widget under the shape palette, or add a drop shadow layer style.
Changed the for how paths to your workspace documents are saved. This means on the first launch of 3.2, your workspace won't be remembered if you are on 10.6 (this does not effect 10.7 folks). However, later workspaces will be remembered.
The "Layer on Images in Acorn" no longer automatically closes documents.

Fix: Fixed a crasher when applying a layer style preset.
Fix: Fixed a bug where your selection was lost when performing a transform on a layer with a selection.
Fix: When dragging an image out of the layers list to the desktop, a PNG was written without the correct DPI. This has been fixed so it writes the correct DPI to the image now.
Fix: Sometimes when you rotated rectangle or oval shapes that were rotated, the location in the canvas would change. This has been fixed.
Fix: JPEG 2000 files now save and export with transparency.
Fix: Fixed a problem where moving a rotated shape would cause strange drawing.
Fix: Acorn would switch spaces on 10.7 when you were in full screen mode on 10.7, and you tried to move a canvas guide. This issue has been squashed.
Fix: Some filters (such as the sunbeam filter) did not show the correct results in the canvas preview. This has been corrected.
Fix: Drawing on a quickmask or layer mask when you had the opacity slider set to to something other than 100% would delay the showing of the output. This has been fixed.
Fix: Corrected an issue where sometimes free rotating a canvas exactly 180 degrees would increase the size of the canvas unexpectedly.
Fix: Undo was sometimes broken after using various Automator actions in Acorn. This has now been corrected.
Fix: Acorn would crash when opening up PSD files which had more than 190 layers. In cases where a PSD has more than 190 layers, Acorn will now open up the image as a single layer.
Fix: The bezier tool works a lot better when snap to pixel is turned on.
Fix: Numerous drawing and behavior fixes when using the bezier tool + zoomed into the canvas.
Fix: When zoomed way in on a selection, the marching ants now correctly draw in straight lines between adjoining pixels.
Fix: The View ▸ Enter / Exit Full Screen menu item now correctly updates depending on what state the window is in for 10.7 folks.
Fix: Fixed a crasher when selecting the Depth of Field from the filters sheet.
Fix: Fixed a crasher when using the instant alpha tool. My undying gratitude to Jeff Buck for finding a reproducible case for this.

Fix: Now reading in the correct color space when opening a PSD file.
Fix: Fixed a crasher when using the magic wand tool with bitmap layers of a certain frame.
Fix: Fixed a bug where sometimes the sliders on the gradient preview would become unresponsive.
Fix: Fixed a crasher when opening up certain PSD files.
Fix: Improvements to the bezier tool when snap to pixels is turned on.

Other: Acorn is now building in Xcode 4.2, various framework bits have been moved around, and there's even an experimental sandboxed version of Acorn on the latest downloads page if you want to play with it.
Other: There's a new hidden pref, using a different text rendering path for Acorn. To enable it, open up Terminal and paste this in:
```
defaults write com.flyingmeat.Acorn nsTextDrawing 1
```
It hasn't been fully tested yet, but it does fix some issues with the current text path.

Acorn 3.1.2 October 11, 2011

Fixed a possible crasher when using the gradient tool.
Change: To scale the image while resizing the window, you now have to hold down both the command and option keys (previously it only took the option key). This change was made because on 10.7, holding down the option key when resizing a window from a corner will move all corners at the same time.
Fix: Acorn would draw slowly when working on a shape layer and you had a New View window open at the same time.
Fix: An issue where a Acorn would crash when opening up the iPhoto Library has been corrected.
Fix: An issue where holding down the option key with the brush tool selected would not update the brush preview correctly with a new color.
Fix: An issue where a bitmap layer could disapear when changing the color profile has been fixed.
Fixed some memory leaks.

Acorn 3.1.1 September 23, 2011

Fixed a bug where opening a zero length PDF would crash Acorn.
Fix: Turned off support for automatic background termination in 10.7.
Fix: Hiding the palette with the tab key and then trying to use the brush tool where it just was would previously fail. Now it works as expected. Hurray!
Fixed a bug where using the eyedropper tool to pick up a color wouldn't draw with the right color depending on what the colorspace your image was in.
Fixed a bug where you would get an error after a warning when canceling a save for an image in a flat format when you had multiple layers.

Acorn 3.1 September 19, 2011

New: Native 10.7 full screen support.
New: Acorn now supports 10.7's autosave and versions features (but it's off by default- turn it on in the preferences window).
New: You can now change the image's color profile with the Image ▸ Assign Color Profile… menu item.
New: You can now select a default color profile in the advanced prefs.
New: If you have PDF content on the clipboard and a shape layer is currently selected, Edit ▸ Paste will insert a special PDF/vector shape into the layer which doesn't care what size you scale it to. So if you want to make a complex vector shape in another application that will copy PDF content to the clipboard, you can then keep that shape in a vector format in your Acorn image.

Change: The default color space is no longer the device color space, and is now "Generic RGB".
Change: It's now easier to drag and drop folders onto Acorn's icon in the Dock (for opening an image browser).
Change: Rearranged the preferences window a bit.
Change: Now using cmd-control-f to enter and exit full screen (the single keystroke 'f' still works as well)
Change: The opacity layer style now shows it's value as a percentage instead of a decimal number.
Change: The default location for the Drop Shadow filter and layer style has been moved a bit.

Fixed a bug where saving as a PNG while you were in a crop would not render all layers to the saved file.
Fixed a bug where duplicating a layer by option dragging it would sometimes put it in weird locations.
Fixed a bug where the "Keep aspect ratio" button could be disabled with the Lanczos scaling algorithm selected (which can only scale keeping the aspect ratio).
Fixed a bug where using the Image ▸ New Image from Layered Screenshot would clip the main window's shadow on 10.7.
Closing a document while it has a web export window open will now close that web export window.
Fixed a bug where the Bring Forward command wasn't working correctly for the very first layer.
Fixed a bug where using levels would sometimes cause your layer to jump.
Holding down the space key while making an elliptical selection will move the origin of the selection.
If a crop preset is too big to fit on the current canvas, it is now scaled down to fit.
Fixed a bug with the Do JavaScript Automator Action, where your changes wouldn't always be saved.
Fixed some drawing bugs when using the brush or pencil tool with a drawing opacity not set to 100%.
Fixed a bug where images would be left open after you closed them (only on 10.7).
Fixed a bug where the effects from layer styles weren't fully updated in realtime when scaling an image.
Fixed a bug where the font panel wasn't always updating correctly when you selected some text.
Fixed a bug where inverting a selection would sometimes give weird bounds.

Fixed a hang where scaling down certain text would crash Acorn.
Fixed a bug where Acorn was not able to draw straight lines with the brush tool when you were using a stylus + shift clicking between points.

Fixed a crasher for certain PSD files created from Fireworks CS3.
Large PSD files will open a bit faster now.
New button to bring up layer styles in the bottom of the palette.
Removed the "Make a new layer when drawing shapes" preference because it hasn't worked for two major releases, and nobody noticed till yesterday.
Fixed a bug where dragging a filter box in the filter panel would sometimes cause a ghost image to show up in the preview window.
Fixed a bug where the feather selection command wasn't always working correctly.
Fixed a bug where negative float values in the styles window were being truncated to whole values.
Fixed a bug where web exported WebP images were coming out with a red tint to them.
Layer styles are now scaled when you resize your image.
Added "Add Layer Mask" and "Enable Layer Mask" to the Layers menu item.
Fixed a bug with the offset filter.

Fixed a bug where creating a new graphic on a shape layer with a really big drop shadow layer style would draw incorrectly.
Generator layer styles (like circles, gradients, checkerboard) now have an overlay option which is enabled by default. We've also removed the source atop blend mode, since this did the exact same thing as the overlay button does now.
Fixed a bug where the bold button in the font palette wasn't working correctly.
Fixed a bug with moving a selection on a bitmap where cutting was involved and it's much too involved to actually explain here. But it works as expected now, so that's good.
Fixed a bug where the registration certificate (non app store versions) would show your old registration number.
Fixed a bug where the canvas wouldn't show up on new documents for certain document sizes.
Fixed a PSD import bug where the pass through blend mode for layer groups wasn't showing up correctly.

New: 5 new fonts- Lobster, Chunk Five, Prociono, OFL Sorts Mill Goudy, and Raleway Thin.
New: Additional scripting api to insert layers from a path on disk (via jstalk scripting): var newLayer = doc.baseGroup().insertLayerWithImagePath_atIndex("/Volumes/srv/Users/gus/Pictures/AnotherImage.png", 1).
New: The shape tools now have tooltips above them.
New: New Filter ▸ Stylize ▸ Inner Shadow filter + layer style.

New: There's a new pref to autoload a palette when using keyboard shortcuts for tools (such as 'b' for brush, or 'v' for the arrow tool). With this option disabled, click on the icon for the corresponding palette to show up in the tools list. This makes it easier to switch back and forth from the shape or text tools to another tool, without losing the palette's focus.

New: Acorn can now use Quartz Composer compositions as filters, which adds over 30 great new filters for you to use.
New: The Edit ▸ Fill… command will now bring up a window allowing you to select a specific color or image from the clipboard, plus opacity and blend mode for a fill.

Fixed a bug where selections where drawing incorrectly when you had the selection mask set to "Clipped Out".
Acorn is now a bit nicer to text when scaling down.
Acorn now provides an option to draw the grid as a series of dots (when normally it's just a line). Turn this on under View ▸ Grid Settings…

Fixed a case where saving a image size preset in the New Image panel wouldn't always save correctly if you had an image on the clipboard.
Fixed some drawing issues with the rect and freehand selection tools.
If you clicked the close button on the tool palette, hitting the tab key (which would normally toggle the tools palette visibility) wouldn't bring it back. It now does.
Fixed a bug where rasterizing a shape layer would draw the shapes in the wrong z order.
The transform tools will now snap to guides and document bounds when turned on.
Previously, pressing the escape key while in full screen mode and using a transform tool would cause you to exit full screen mode. Now it just cancels the transform tool.
Fixed a bug where sometimes Acorn would delete the wrong layer when you were currently transforming the image.

The elliptical and rect selection tools now snap to guides.
The marching ants for selections are now drawn over any guides that might be showing.
When option-dragging selected shape layer graphics to copy them- the relative z order of the graphics wasn't always kept the same. This is now fixed.

New menu item: Edit ▸ Paste Into, which pastes into a new layer, using the selection as a mask for that new layer.
New hidden pref: defaults write com.flyingmeat.Acorn useEdgeColorForFullScreen 1
When rasterizing a shape layer, if your layer name starts with "Shape Layer", Acorn will replace that with "Bitmap Layer".
If you have a group layer selected, and you use the Edit ▸ Copy menu item, you'll get a composite of just the group layer put on the clipboard.
Hold down the option key when selecting a crop preset will cause the width and height values to be swapped. So if you wanted a crop of 3x2 instead of 2x3, just hold down the option key when choosing the preset.
Updated some menu items to conform with the Apple HIG.
If you're using the arrow tool, and you've got a group layer selected, clicking on a layer within the group will move all layers inside that group (this hasn't changed). However, if you now click a layer that isn't inside the selected group layer, the clicked on layer will then be auto selected and you can begin moving that guy.
Fixed an undo bug when adding a text box to a layer, where an extra text box would incorrectly be removed.
Acorn now uses a "near by" algorithm to find which pixel you wanted to start with, instead of flooring points when doing selections and other operations (most visible when you're zoomed in).
When using the simple transform tool, the scale and angle fields (in the palette) will update the image in realtime without needing to tab out of the field first. You can also use the up and down arrows to change the values.

-- AppleScript:
tell application "Acorn"
	open "MyImage.acorn"
	tell document 1
		deselect
		select oval rect {100, 100, 400, 600}
	end tell
end tell

// JSTalk:

Cmd-4 currently zooms you to 800%. However, if you're already at 800%, and you hit it again, it'll zoom to the max, which is 3500%. Which is kind of nice when making new cursor icons.
If you hold down the option key while hitting 1-9, and 0 - it works just like setting the opacity of the current layer, EXCEPT- it changes the opacity of the pencil or brush tool.
Fixed a bug with the Brush Designer, where it would freak out if you had the opacity set to something other than 100% with the brush tool.
You can do math and stuff in most of the palette fields. The up and down arrows also work to increment/decrement the values. Hold down shift to go 10x faster.
You can now option-drag (with the move tool) between canvases to duplicate one layer to another document. Works in the same document as well.
