• Finder Quick Look for .butterkit files: Preview your projects directly in macOS Finder. Select a .butterkit file and press Space (or use the preview pane) to see what's inside without opening the app. • UI improvements

• Updated App Store screenshots and metadata

• Updated app icon, brand colors, and refined UI • Improved Settings UI • Added an easy-to-dismiss "What's New" announcement with link to changelog • Bug fixes

• Adds support for macOS 27 + Xcode 27 Beta: In Xcode 27 the Simulator app is replaced with the new Device Hub, and ButterKit Capture Widget now attaches to it automatically. It follows whichever device you select in the Device Hub sidebar, and capture, status bar overrides, and language relaunch all work as before. Everything continues to work exactly the same on Xcode 26 and earlier. • Improves animations on ProMotion displays

• Fixes memory leak during large multi-language exports and reduces memory usage • Improves reliability of cloud translations • Fixes an issue where Apple Watch designs couldn't be uploaded to App Store Connect (thanks Frederique) • Improves App Store Connect upload user experience and status

• Fixes an issue where a linked folder of screenshots could sometimes result in missing items (thanks Falk) • Minor bug fixes and improvements • Reduces app bundle size

• Images, logos, and badges can now be rotated via the Inspector w/ MCP support included • Reduces memory usage when exporting large sets to App Store Connect (thanks Albert A) • Improves 3D device Inspector labels (thanks Sarandi) • Improves license handling; now properly shows status in the UI (e.g. maximum number of devices activated etc) • Fixes an issue where a linked folder of screenshots could sometimes result in missing items (thanks Falk)

• Fixes a memory leak that could occur when uploading many screenshots to App Store Connect (thanks to everyone who helped track this down) • You can now select specific localizations to upload to App Store Connect, instead of uploading all of them or one at a time

• Faster rendering and compositing engine, now leans more on SwiftUI • Improved memory/RAM usage • Tuned animations and transitions • Faster App Store Connect uploads (improved batching and parallel processing) • More intuitive canvas editing and organized artboards • Screenshot callouts can now be customized per localization • MCP reliability improvements • Fixed linked localization folders sometimes showing wrong images

• Introducing Text Backgrounds: add highlighted text, pill badges, and label backgrounds to your screenshots. Pick a color, adjust the corner radius, done. Works automatically across all your localized languages: the background adapts to each translation so you never have to manually resize. • Improves Capture Tool "Target Artboard" dropdown to include the exact locale for more clarity (thanks Filip!) • Improved MCP reliability and crash logging (thanks Simon and Habitoti)

• Cloud-translated metadata now preserves paragraph spacing, so your App Store descriptions keep their intended formatting across all languages • Capture Tool is now easy to disable. If you use your own capture method (e.g. Fastlane), you can disable the Capture Tool from Settings. • MCP edits now refresh reliably. Fixed a bug where changes made by AI agents through MCP wouldn't update the artboard, leaving you looking at stale artboard renders.

• Introducing Callouts: a new way to highlight your features or UI in your App Store screenshots - give it a try, add a callout in the Inspector > Devices tab • Improves loading process and user experience for large documents • Improves onboarding, UI and adds more butter

• Starting a new project in ButterKit just got a lot smoother • New template picker at project creation.

The MCP helper now exits quietly if ButterKit isn't already running. To restore the old behavior, add "--auto-launch" argument to your MCP config. More info available in the docs. • Clicking empty space in the artboards panel now deselects artboards, just like it already did on the canvas (thanks Robert M!)

• New: AI agents can now add and position images on your artboards -- logos, icons, badges, and more. Just set an Agent Import Folder in Settings > AI Agents (MCP) > File Access so agents know where to find your assets • Fixes issue where Simulator Capture Tool could stop working properly on Xcode 26.4 • Improves error handling

• Fixes MCP issue where some AI agents had trouble discovering ButterKit's MCP tools • Adds MCP logs to assist with troubleshooting: available in ButterKit Settings > MCP > Diagnostics • Improves default artboard styles created by MCP agents • Improves MCP settings UI: now shows details of connected MCP clients

• Fixes issue with MCP screenshot discovery. You can now grant your AI agents (Codex, Claude, Cursor, etc.) access to a screenshot folder (or parent folder) via ButterKit Settings > MCP > File Access. • "Copy style to..." now ignores padding and position, so you can apply text styles across artboards without overriding layout.

• Introducing MCP support (beta): let AI tools like Claude or Cursor control ButterKit directly • Fixes bug where linking a folder of screenshots would sometimes apply the wrong localization

• New: Delta Translation — ButterKit now tracks which text blocks changed and only re-translates those. More predictable results, lower token usage. No more re-translating your entire project because you fixed a typo. • New: Preview Navigation — Dedicated left/right buttons + keyboard arrow support in the Preview window. (thanks David M) • New: "Delete artboards?" confirmation modal to prevent accidental deletion. (thanks Discord crew) • New: Toast notifications after translation so you know when it's done. • Fix: Device Overflow alignment — Multi-panel exported images no longer misalign. (thanks u/habitoti) • Fix: Device Overflow + rounded corners now appears correctly in the editor. • Fix: Preview spacing now more closely matches the actual App Store layout. • Fix: issue where some projects would open with a non-interactive ghost artboard containing locked text. Projects affected by this condition will now initialize correctly. • Fix: you can now properly multi-select and make batch updates in the Localization Panel (e.g. to change Translation Provider for many languages).

• Adds a highly requested feature: "Do Not Translate" text toggle! Now you can disable automatic translation for specific text blocks, useful for delicate designs or product names and more. To toggle this, just open the Text Inspector, select the text block, and scroll to the bottom to find the new "Do Not Translate" toggle. • Improves Undo coverage and reliability • Improves Cloud translation model support, now more robust in fallback situations • Fixes issue where some fonts would not apply proper bold font weight when "Fit on 1 line" mode is on • Images like logos etc can now be moved to negative X/Y values for more flexible designs • Enhanced toast UI • Moves text colors control up slightly to be easier to reach • Improves "Fit on 1 line" mode: text now stays centered vertically for more predictable results • Improves pinch-to-zoom accuracy; the camera now more accurately follows the cursor • Fixed line-height issue where the bounding box would expand upward, causing unexpected layout shifts. Line-height now behaves more consistently.

ButterKit now batches artboards more efficiently, much faster in testing! Thanks to Carsten on this. • Fixed: Undo now works much more reliably when adding/removing screenshots • Fixed: metadata sometimes wouldn’t save (thanks reddit folks for help on this!) • Fixed: String Catalog is now more reliably discovered by the Capture Tool (thanks Timo!) • Fixed bug where backgrounds sometimes didn't appear when switching localizations • App Store Connect metadata now validates to check for emojis before upload (thanks Kristoffer) • It's now easier to choose what type of artboard you want to add. Just tap the ⋮ button next to "Add Artboard" • New text character count UI

Happy New Year! This release adds screenshot folder-linking support for tools like Fastlane (highly requested), improved text editing controls, and dozens of UI refinements inspired by your feedback. • New: Optionally link a Fastlane or image folder and ButterKit will automatically apply (and update) images to your 3D devices, even organizing by localization and devices. To use this, de-select all artboards and add a linked folder in the “Project Settings” Inspector. • New: Additional text editing controls for variant artboards (font style, size, color and more), and more intuitive UX for controlling linking to source. • New: Undo system is now much more reliable and comprehensive, allowing for easier undo/redo while editing • New: Manual translation mode is now available. Simply choose “Manual” as the translation provider to input your own translations. Easily switch Translation Providers later if you wish. • New: Welcome Splash now shows recent projects (thanks Franklin!) • Fix: Improved reliability of Capture Tool • Fix: Improved UI, tooltips, onboarding and polish

The ButterKit holiday update is here, and it includes some exciting new features and user requests. Thanks for supporting ButterKit, please keep the feedback and requests coming. Happy Holidays, everyone! • Seamless Backgrounds: apply a single “ultra-wide” background image to a group of artboards and ButterKit does the rest, splitting it up so the artboard backgrounds blend together • New 3D models • Templates: a newly designed templates section on the website + support for landscape screenshots • Improved color picking UI • Improved Device Overflow: the calculated ‘gap’ between images is now properly accounted for automatically, resulting in more seamless designs • Improved reliability of App Store Connect uploads • Additional support for landscape screenshots and App Store Connect uploads • Changing a size preset now automatically swaps the 3D device for you • Watermark (free licenses) now looks nicer • Re-ordering artboards is now easier and more clear • Numerous bug fixes and UI tweaks for a more polished experience

• Fixes issue where text scale would sometimes appear at different sizes on different DPI monitors (thanks Hugo!) • Fixes issue where some language pairs would fail local translation • Fixes issue where some specific regions would be uploaded improperly into App Store Connect (e.g. English UK would upload as English US). You can now choose your region preference by right clicking on the localization and selecting it, and ButterKit will attempt to respect it when uploading • Fixes issue where exporting hundreds of arboards would sometimes freeze due to overwhelming the CPU. ButterKit now queues exports efficiently to prevent this, leading to smoother rendering of hundreds of artboards at a time (thanks Wendy!) • New: Improved UI for localizations, added ‘downloaded’ indicator for language packs already available on your machine • New: You can now manually set a document’s source language from Localizations. This setting is saved with the project and shared with your team.
