# New Stuff * 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. # Fixes * Acorn’s Export window now disables the progressive option when JPEG 2000 is selected as the format, since the encoder doesn’t support it. Also fixed a bug related to this where the preview would not update correctly when the progressive option was toggled for formats that support it. * Fixed some printing problems where images might have too much whitespace around the margins. * Fixed a bug where using the poly select tool on shape layers wasn’t always very accurate. * Fixed a problem where two saved brushes with the same name would have loading conflicts. * Fixed a problem where the HEIC encoder would not work correctly in web export if you had "embed profile" turned off and a non-RGB color profile selected. The fix was to always embed the profile in this case. * Fixed an issue where layers with masks would not appropriately allow mouse click throughs to layers below them. Read the release notes on website for the full list of changes. 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.

## New Stuff # 8.6.3: * Support for the latest OS release. # 8.6.2: * The `acorn` shell tool now has a `-screenshot` argument which tells Acorn to take a layered screenshot of all your open windows. You can pass the `-delay` argument with a number of seconds to wait before taking the screenshot, and you can also pass the `-appname` argument to only include windows from the named app. Running `acorn -h` will give a full list of available options. * Acorn’s Dock menu now has an option to take a layered screenshot. This is pretty handy because you can have all your windows exactly how you want them, and then control click on Acorn in the Dock to take your screenshot without any windows losing focus. ## Changes * Filter presets previously didn’t respect the canvas selection on bitmap layers when they were being used. We’ve changed it so filters are now masked to the selection. * When exporting as PSD images, Acorn doesn’t add any extra pixels to bitmap layers when it’s not necessary now (ie - it keeps the existing pixel bounds instead of matching that of the canvas. This should make file sizes smaller). * Updated the x/y labels in the Crop, Scale Layer, Perspective Transform, and Smart Layer Export palettes so they are consistent with the rest of Acorn. * When loading a new brush preset, Acorn will check and see if the velocity settings have been saved previously (either on or off). If it has not then the new brush preset will inherit the current brush’s velocity changes. This means if you turn on or off “velocity changes width” and switch to an older preset, it will respect the current option. ## Fixes * Fixed a little problem where using File ▸ New from Clipboard with a URL would throw up a SVG error (but eventually download the image at the end of the URL!) * Fixed a problem where the clone tool would draw little artifacts when the blending opacity was less than 100% * Fixed a problem where using the Export With Preset menu item would not remember to use the resize options saved in the preset. * Fixed a problem where the mouse location in the vertical ruler wouldn’t update in the correct location. 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.

# New Things in Acorn 8.6 * The brushing engine has been completely rewritten, and uses Metal shaders to do its drawing. It’s crazy fast. I *heart* Metal. * Smudge, clone, burn, and dodge also use the new engine. Smudging is so much faster than it was before, it feels so good. * The Crop palette has a new “Keep aspect ratio” option that does what it says and kicks in when you’re resizing the bounds of a crop. Honestly, I’m not sure why we haven’t had this option visible before, but I’m glad to have it for you now. Cheers! * Pressing ⌥↩ (Option-Enter) will move keyboard focus to the layers list to begin renaming the current layer. Cool. Other things you might not know: * Pressing Enter on a selected text box will begin editing it. * Pressing Enter on a shape layer will bring up the Quick Process window. ## Other things that we you get with the new brush engine: * A new setting for “Velocity thinning”, where the faster you draw your brush strokes, the thinner the lines. * Brush blending/compositing is done with linear interpolation, making a more painterly blending between colors. * The Brush Designer will now keep previous test strokes, so it’s just like drawing on a regular layer. However, we’ve kept the ability to dynamically change your last brush stroke in realtime by adjusting the brush properties. And of course, redrawing is much faster. # New Automation and JavaScript Things Lots of interesting JavaScript things this time around, which are too big to put in here. Make sure to visit our release notes from the website. But here’s a taste: a new `acorn` shell tool, you can pipe JavaScript to it, and AppleScript’s "do JavaScript" command now returns a value. We’ve also added a new option to disable JavaScript automation under Acorn’s Settings ▸ Advanced tab. So if you want to opt out of it, you can. And if you want to drive Acorn using a LLM, you can now setup Acorn as an MCP server or point it to /Applications/Acorn.app/Contents/Resources/skills/acorn-javascript-api/ and it’ll figure out the rest. For instance, you could ask: “Ask Acorn to take a layered screenshot, and hide any layers that aren’t from Safari. Then export each visible layer to /tmp/ as a PNG.” And if the LLM is having a good day, it’ll figure out how to do what you’ve asked. Acorn also has a new JavaScript API Reference page, which lists out all the supported APIs you can use to automate Acorn. # Changes * The ML models used for Super Resolution, Remove Background / Mask Subject / etc… are no longer included by default. Instead, Acorn will download them the first time you try and use one of those operations. By making it an optional download, we’ve trimmed up the size of Acorn’s application size quite a bit, and if you never use these features, why take up the disk space? It will also make updating Acorn’s app quicker since it’s no longer included. We’ve also heard from a number of you that you don’t want to use apps that include a whiff of AI, so this is a little nod to you as well. # Other * SVG import improvements. Always making it better. * When searching the filters via the filters panel, Acorn does a much better at fuzzy matching now. * Got rid of the sliding animations in the layers list when you add or remove a row. Acorn feels faster without them. * Updated Russian localization. * Removed the option in the pixel tool to use stylus pressure. # Fixes in 8.6.1 * Fixed a problem where the new brush engine was not working correctly with canvas selections. * Fixed a problem where the new brush engine was not working correctly with some older Intel GPUs. * Fixed a problem where the new brush engine might not work for people who had the old “Backing:” preference set to “CPU Memory”. 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.

New in Acorn 8.5: # New Shape Things • Arrows have a new style: Bendable. With this option selected in the new Arrow shape palette, you can make your arrows curve across the canvas. We’ve also added the option to have an arrow head at either end of your line (and much rejoicing was had). • There is a new Shape Processor named Random Location from Circle which will either randomly move all shapes inside, outside, or along the edge of the adjustable circle. This is handy if you are making abstract art or custom wallpapers for your phone or desktop. # New SVG Things • The SVG parser for Acorn has been updated to support more element types, styles, and other SVG goodies. • Text on a path is now supported. • Embedded images are now supported. • Poly lines and referenced elements are now supported. • Improvements to the path importer, now supporting rarely used path instructions. • Drop shadows on elements are now supported. • Element transforms have been greatly improved. • Opening a SVG as a single layer bitmap: Holding down the option key when opening a SVG will render your image as a bitmap. This uses the WebKit (aka, Safari) framework to rasterize the SVG, and it should look just like it does on the web. • Lots of other little things. Acorn’s importer is much improved, but if you come across a SVG that it can’t import and you think it should, make sure to send it to us: support@flyingmeat.com # New Other Things • The Linear Multi-Stop Gradient and Radial Multi-Stop Gradient filters now support a couple of different color interpolations: Document, sRGB, Perceptual (Oklab), and Linear. Oklab is a great choice, and it’s now the default when creating a new filter. • When exporting an image as TGA you can now set the compression options. • You can now toggle the window UI by pressing the keys Option-Tab. Pro tip: Did you know pressing the Tab key will toggle all the palettes? • The RAW Import and New View windows now have overscroll and better zooming capabilities. • Drop shadows from layer effects are now imported from PSD files, and exported to layered PSD if you have a drop shadow layer style in an Acorn image. • New “Clear All Measurement Rulers” Action Bar item that will remove all the on canvas measurement rulers. • Clicking down on your scroll wheel mouse button (if you have one) will now let you pan your image around. # Other • Renamed the Shape ▸ Align ▸ “Vertical / Horizontal Distribute Center” menu items to “Vertical / Horizontal Distribute Bounds”, which more accurately reflects what it does. • New Command Bar actions: Horizontal Distribute Left Edges, Horizontal Distribute Right Edges, Vertical Distribute Top Edges, Vertical Distribute Bottom Edges. • The Zoom tool now defaults to having the pref “Scrub zoom” turned on. You can change this back to the previous default in the Zoom palette. • Updated German, French, and Spanish localizations. # Changes • General performance improvements with Bézier paths and arrows. And they use less memory now as well (which is awesome because we’re in the middle of a global memory shortage and we need to save all the bits we can). # Changes in 8.5.1 • Added a Data Merge… menu item to the File ▸ Export menu. (You’ll still need to setup a Data Merge first via the Image ▸ Data Merge Settings… menu item. # Fixes in 8.5.1 • Fixed a problem where images were no longer opening in tabs. • The tool palette lays out a little nicer when in full screen and edge to edge canvas is turned on. • Fixed a problem where the rotation handles for selected shapes were not always showing up. And more. Check the full release notes on our website. If you like Acorn, we’d love it if you could take a moment and give it a nice review.

You can change this back to the previous default in the Zoom palette. • UI refinements. • Bézier path editing refinements. • Holding down the Option key while clicking the Dock icon in the Settings… ▸ Mueller tab will reset it to the default on whatever system you are on is. So if you’re using tinted icons and don’t want either selection, this will come in handy. • Tweaked how images are opened a bit, so they open centered if multiple tabs are already visible. • Updated German, French, and Spanish localizations. # Changes • General performance improvements with Bézier paths and arrows. And they use less memory now as well (which is awesome because we’re in the middle of a global memory shortage and we need to save all the bits we can). And more.

# New Stuff in 8.4 • You can now set or change the GPS metadata for your image in the File ▸ File Info… menu item. • New File ▸ Export ▸ Export With Preset menu item, where you can find all your carefully crafted export presets available. With this new menu item, you can skip the preview window with all the great settings, and just save your image exactly how you want it. • New Command Bar Action: “Fill Selection With Average Corner Color”. Looks at the top left, bottom left, top right, and bottom right pixels on the edge of the selection, and fills with the average color of those pixels. Works best for rectangular selections, great for erasing elements of a screenshot. There’s also a new “Fill Selection With Average Selected Color”, which is similar to the previous command, but looks at all the selected pixels (and works best with non-transparent rectangular selections). • You can now export images in the AVIF format, via the File ▸ Export ▸ Export (Web & Other) menu. In general, this only available for macOS 26 or later. However if you have the avifenc tool installed, Acorn will detect this and use it for encoding of AVIF files. It currently looks in both /opt/homebrew/bin/ and /usr/local/bin/. Alternatively you can also set the avifencPath default with a full path to the encoder you’d like to use. • Two new filters for masking content - Circle Mask and Rectangle Mask (under the Generator category). They have options for size / radius, masking inside or outside the shape, a blend mode, and color of course. You can use this to darken areas of your layer, or even use it to cut out areas of your image using the Destination Out blend mode. # Changes • The default font size for images is now based on how big an image is (instead of always defaulting to 12px). # Fixes • Various stability and performance improvements (specifically for Apple Silicon Macs). • The Trim out Selection command now behaves a little nicer with shape layers. • Fixed a problem where the Offset and Wrap Layer palette might throw a warning up on empty values for the x/y fields. • Fixed a problem where the zoom palette mini-canvas would sometimes flicker when panning around the canvas. • Fixed an issue where converting a bézier shape to outlines would not render rounded end caps correctly when doing so. # Changes in 8.4.1: • Tweaks to how Animated GIF, Animated PNG, and SVG previews are rendered on export, so scaling, panning, comparing to the original, and other such things work exactly like they do for other formats (excluding PDFs). You can even split view compare animated images now, which is fun. # Fixes • Fixed an issue where sometimes an image would initially open with blank white canvas for a small number of folks. • Fixed an issue where the custom color well in the Canvas Resize wasn’t quite working as well as it could have when you selected options from the pulldown. • Fixed an issue where using a custom avif encoder could crash Acorn. • Fixed an issue when using a custom avif encoder, the color profile would not be embedded. # Other • Updated French and German localizations. 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.

# Changes * Measurement unit you choose for rulers is now a global setting, and no longer a per-image setting that gets saved with .acorn files. The reason why it’s been changed is because have a per-image setting was causing confusion, and I think it’ll just be nicer to have the setting able to change in one place and it changes everywhere. * The Export window will now default to the last used color profile when exporting (which is probably sRGB for most folks). Previously it would default to the document profile. If you’d still like the original image color profile to be selected, you can select it from the top of the Color Profile popup, or use the shortcut key ⌘⇧K (Command-Shift-K). * The Flood Fill tool (aka “Paint Bucket”) now has a blend mode option. * Tweaks to how App Store receipts are verified (App Store version of Acorn only). # Other * Using Select All or Clear Selection on Shape Layers with more than 10,000 shapes got a lot faster. * The Redraw Layer filter now has a blending option. * Tweaks to the RAW Import UI. * Added a new Spanish localization (send feedback if you have any!). * Updated German and French localizations. # Fixes * Fixed an issue where the zoom palette wouldn’t update correctly when you had the Setting for floating palettes enabled. * Fixed a problem where viewing the layer filters when the window was set to full screen would truncate some buttons at the top of the list. * Fixed a problem where the selection resize handles were drawing when you were using the polygonal select tool. * Fixed a problem where using the Stroke Selection command would sometimes draw the stroke in the wrong location. * Various UI refinements that were driving Gus a little crazy. * Fixed a problem where the controls below the layers list would not appear when the “Edge to edge images” setting was enabled. * Fixed a problem where the widget to swap colors wasn’t working correctly. * Fixed an issue where you could perform various selection operations when you weren’t supposed to (like when transforming a selection). 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.

# The Liquid Glass Release. # New * Liquid Glass support! If you've updated your Mac to macOS 26 Tahoe, you are now presented with an option for using Apple's new Liquid Glass transparent UI, or you can opt to keep the classic look of Acorn. Why the options? For pro users, we know you're going to want to keep distractions out and clarity in the UI paramount, so you're probably going to keep the glasstastic options off. But for the more casual users who love the new refractions and interface, you're going to love seeing the your canvas reflected back in the palettes. * But what if you change your mind? Acorn has a new Appearance Settings tab, where you can turn on and off the Liquid Glass palettes. You even have the option to have your canvas display edge to edge, without the Liquid Glass palettes. * New macOS 26 Tahoe friendly squircle icon. # Other * When using the Clone Tool, the on canvas brush preview is now drawn with a bit of transparency. We hope this helps with more accurate brushing. * Acorn got a bit smarter about opening images without a file extension, by peeking into the file and making a more informed decision about what kind of image it is (I'm looking directly at you, DICOM X-ray images). # Fixes * Fixed an issue where Acorn could get stuck at a specific zoom level when using the Command+ or Command- shortcuts. * Fixed an issue where using the clone tool when zoomed way in could make your cloned areas a little blurry. * Fixed a problem where the eraser tool would use the alpha value of the current fill color, instead of only relying on the the Flow setting to control how much is erased. * Cleaned up button spacing in the Settings window. * Cleaned up some localizations. * Other minor bug fixes. # Fixes in 8.3.1 * Fixed a problem for folks with the Setting “Float inspector palettes in windows” set to true, where you’d get double tool palettes. * Fixed a problem where the shortcut for deleting a bézier path anchor (clicking it with Command-Option down) wasn’t working. * Other bug fixes and improvements. # Changes in 8.3.2 * Change in how the Horizontal & Vertical Align Center commands use for multiple selected layers. Previously they would center themselves in the canvas (either splitting the width or height as it’s center point). Now it’ll use the optical bounds of the selected layers. This results in the layers moving less, and maybe a bit more predictably if you’re used to how other image editors might behave. * Slight behavior change when transforming selections. It used to be that when you had selection on canvas, you would use the Move tool (v) to begin transforming the selection (without changing the layer). Now you need to have one of the selection tools (rect, oval, magic wand, etc) selected to start modifying the selection bounds / resize it. If you have the Move tool selected and you begin resizing a selection, Acorn will begin modifying the selected pixels and not just the selection. It’s a more natural and expected way to work with selections. # Fixes in 8.3.2 * Fixed some layout glitches in the tool inspector and Settings window. * Fixed a problem where new layers weren’t always showing up in the layers list when Acorn was set to have floating palettes. * Localization updates and fixes. * Other bug fixes and 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.

# The Liquid Glass Release. # New * Liquid Glass support! If you've updated your Mac to macOS 26 Tahoe, you are now presented with an option for using Apple's new Liquid Glass transparent UI, or you can opt to keep the classic look of Acorn. Why the options? For pro users, we know you're going to want to keep distractions out and clarity in the UI paramount, so you're probably going to keep the glasstastic options off. But for the more casual users who love the new refractions and interface, you're going to love seeing the your canvas reflected back in the palettes. * But what if you change your mind? Acorn has a new Appearance Settings tab, where you can turn on and off the Liquid Glass palettes. You even have the option to have your canvas display edge to edge, without the Liquid Glass palettes. * New macOS 26 Tahoe friendly squircle icon. # Other * When using the Clone Tool, the on canvas brush preview is now drawn with a bit of transparency.

We’ve got a handful of big things and a ton of little things for you in this update. And 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. # Export (Web & Other…) Improvements * You can now view differences and split screen between images with the new View popup in the export window. Switch between the various views with the 'a' (view exported image), 'b' (view original image), 'd' (view difference), 's' (split view), and 'g' (view out of gamut highlights when the original image has a wide gamut profile) keyboard shortcuts. * You can now set the bits per component of an image on export to 8, 16, or 32 (hurray for deep color!) * Related to the previous item - the Export canvas will now render your images with deep colors if the depth is greater than 8. * We’ve made tweaks to the layout and locations of buttons in the Export window, to get ready for future OS updates. * Improved scrolling, scaling, zooming in the preview canvas; and now overscroll has been brought to the export preview canvas as well. # Other New Stuff * New Linear & Radial Multi-stop Gradient filters, which work like the normal non-destructive Linear Gradient / Radial Gradient filters, but now with more colors. You can find these wonderful new filters in the Filter ▸ Gradient menu. * The new image diff stuff in the Export window is pretty cool, so we’ve also put it in a new Command Bar action named “Compare Two Front Windows”. * Zoom modifiers when using the panning tool via the spacebar. As you know (or if not, now you do!) you can temporarily switch to the panning tool by holding down the spacebar. Now if you hold down the spacebar, and then press the Command key, Acorn will temporarily switch to the scrub zoom tool. So you can quickly zoom in and out without switching tools. (This is standard image editing behavior, which we’re happy to bring to Acorn). # Smaller New Things and Changes * The blend mode popup now shows a little icon next to each item with a little representation of what each blend mode does. * The amount of feathering you apply to a selection is now saved to .acorn files (along with the current selection). The feathering stepper has a new button next to it which bakes in the feather, so you can add new selections that you might not want feathered. * Smart Layer Export now has an option for shared backgrounds between exported layers. Visit the documentation on Smart Layer Export for more information. * Localizations: Acorn now has an Italian localization, and also fills in missing German localizations. * Command-Option-J is a new shortcut for duplicating the currently selected shape(s). * There’s a new shortcut to temporarily toggle snapping: Command-Shift-Option-; * Speaking of snapping, there’s now a snap setting (and pref) for snapping to canvas measurement rulers. * Updated zoom and resize cursors for macOS 15 or later. * There’s a new Fussy preference titled “Convert flat images to .acorn when layers are added”, which will upgrade your .png/.jpeg/.tiff files to Acorn’s native file format when a layer is added. Images are then autosaved (by default) and when you next save, you will be asked to name the file and where to save it. Acorn will use the original image’s name and location by default. * The resize selection handles now only show up when you have the move tool selected. # Fixes & Misc. * A bunch of fixes and tweaks were made, but we ran out of space to put them. You can view the full release notes from our website. # Acorn 8.2.2 Fixes: * Fixed an issue where you’d get a warning if you were running on macOS 26 Tahoe (sorry about that!) * Fixed an issue where the correct Acorn icon wasn’t showing up in the Dock.

# Fixes * Fixed minor drawing issues when using the pixel tool with the “Copy” blend mode and opacity set less than 100%. * Fixed a drawing issue when using the Perspective Transform tool. * Fixed a possible crasher when using the color loupe tool. * Worked around an issue where Photos wouldn’t import changes to edited 16bpc images when transparency was involved. * Fixed a problem where a layer’s opacity could accidentally be set to 1% under various conditions when switching tools. * Various little fixes for working with 64bit images. * Various little tweaks for showing and hiding the system color palette. 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.

# New Features * You can now resize selections with on canvas handles. Once you start resizing a selection, a palette appears and you are able to set the width, height, angle, and more. Press enter to finish up. * New “Crop to Original Bounds” filter, which will will cut out all the pixels outside the original image. This is useful if your image goes through a series of filters that distort it in such a way that the image dimensions grow in size (such as blur filters, distortions, etc). Using this filter will crop it back to the original dimensions. * The RAW Import window got a big upgrade with more options for making your RAW images come out exactly as you’d like. * New “Scrub zoom” preference in the Zoom palette. When turned on, you can zoom in and out smoothly by clicking and dragging left or right on the canvas when the Zoom tool is active. Related bonus features: * You can toggle the “Scrub zoom” preference off and on by quickly pressing the z key. * You can now zoom in to 25600% (up from 6400%). * Tip: You can double click on the zoom slider handle to zoom to 100%. * The Grayscale Filter has expanded the range for RGB sliders from 0-100% to -200-200%. Additionally, it now includes an Intensity slider that controls the blending of the grayscale filter. This enhancement allows for more creative channel mixing when creating monochromatic images. * When using the Crop tool, holding down both Option and Shift keys while confirming/committing the crop will add a selection instead of cropping the image. Tip: Holding just the Option key crops the current layer rather than the entire image. * A new File ▸ Actions menu allows you to place shortcuts, droplets, scripts, and more. This replaces the legacy “File Actions” menu item. You can read more (and learn how to revert to the previous File Actions menu) in the Actions documentation. * Added a new Make New Layer from Subject menu item, which appears instead of Make Selection from Layer when holding the Option key under the Select menu. * Introduced two new blend modes: Linear Light and Vivid Light. # Autosaving Changes There is a new preference in the Settings window for autosave with three options: * Off: This will disable all autosaving of images. * Native Acorn Images: This will enable autosaving and versions support for native Acorn files only (.acorn). * All Images: This will autosave all file types, including lossy encoded images such as JPEG or HEIC. The default is set to Native Acorn Images. In Acorn 8.0, when autosave was enabled, non-native files would open without a reference to the original file on disk. This is no longer the case in Acorn 8.1, where non-native files open with a reference to the original file, and pressing ⌘S will save back to the original, regardless of the autosave setting. # Other Improvements * The Smart Layer Export palette now has options to save as WebP and JPEG-XL. * When exporting images, Acorn does a better job now at stripping out the alpha channel when it’s not needed. * PSD files now correctly import masks for group layers. If you’re using Etsy frame mockups, this one is for you. * If you have multiple shape layers selected in the layers list and use the Edit ▸ Copy menu item, and then use the File ▸ New from Clipboard menu item, the original shape layers will be copied over instead of a bitmap of the layers. SVG data for the selected layers will also be written to the clipboard. * Data Merge import will now allow the prefix '@ (single-quote + @ symbol) to denote an image path, in addition to a single @ symbol. This is for Microsoft Excel compatibility, which reserves the @ symbol for functions. * The pixel grid is now turned on by default when you are zoomed in at or above 1000%. (Also, that value used to be 500%). * Minor improvements have been made to SVG export functionality. * We ran out of room listing everything. Visit our website for the full release notes.

# Bug Fixes. * Fixed a problem where canceling a Data Merge export wouldn't reliably stop the export. Also fixed a problem where Data Merge was consuming gobs of memory. * Fixed a problem where the RAW Import window would preview images with the wrong color profile, making images appear overexposed. * Fixed a problem where sometimes the Data Merge palette wouldn't appear when asked for. * Fixed a problem where you couldn't drag an image from the Finder into Acorn's layers list. * Workaround for a macOS 15 Sequoia Photos bug where using the Image ▸ Edit With ▸ Acorn menu item would send a 16bpc wide gamut TIFF to Acorn, and then when Photos reads it back in, not notice the color profile has been updated and render it darker. Acorn no longer upgrades the color profile in this case, and keeps it exactly what it is given (Apple Wide Color Sharing Profile). (The image will still render in Photos _slightly_ darker, but the same is true if you edit the photo with Preview or any other app. But it's much better than before, and really only with wide gamut images). * Fixed a problem where Acorn sometimes crashed when exporting as an SVG. * Fixed a problem where you couldn't move the anchor points of a Bézier path with text. * Fixed a problem where the checkboard background for the canvas would sometimes get lighter colors when Dark Aqua was the current UI. # Other. * Minor performance improvements for the RAW Import window. 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.
