# 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.

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.
