• Adds support for multiple App Store Connect profiles; quickly change between them in Settings (thanks to zlib, Eran J and others for suggesting this) • Fixes issue where an artboard could be deleted via right click menu and undo didn't work • Improves right-click menus with icons and keyboard shortcuts

• Paste Markdown into the metadata editor. What's New, Description and Promotional Text turn it into plain text App Store Connect accepts, with bullets and links kept readable. Handy if you draft release notes in Markdown. • Pick the Capture Tool's device from the menu at the top of the panel. It no longer jumps to a different simulator when you click back into Device Hub. Thanks to Markus F for helping track this down! • New MCP tool: design_rename_artboard lets AI agents rename your artboards, keeping names safe for export filenames. • AI agents can now span a panoramic background across a row. • New Meadow Meditation template. • Cleaner canvas. Artboards get a crisp hairline edge instead of a soft shadow, and the group name sits as a fixed title. • Fixes a bug where duplicating or resizing a Header or Search Results artboard created a second, identical header in the sidebar, and the App Store Connect upload skipped it. Copies now become regular artboards, so each project keeps one Header and one Search Results. Thanks Pawel K! • Fixes a bug where saving an untitled document over MCP opened a Save dialog and stalled the agent. The agent now gets a clear error instead. Thanks Eran J! • Fixes landscape screenshots showing sideways in the Select Callout Region sheet. • Fixes canvas text shifting when you double-click to edit it. • Fixes text sizes in the inspector not matching what you see across the iPhone Duo row. • Better contrast in light mode for the selected sidebar row and the device pose tiles, with more on the way.

• Redesigned Capture Tool. More intuitive, works in light and dark mode and starts from your simulator’s current settings. • Smarter app picker. The Capture Tool picks your app and lists only apps you installed. • Connect an agent in one prompt. Copy the Setup Prompt in Settings > AI Agents (MCP), then paste it into your agent. • AI Agents can now see your workspace via MCP. The new app_get_context tool reports open documents, the current selection, and which folders the agent can use. • Agents also get workflow instructions when they connect. In my testing, I’m seeing huge improvements in design quality and speed. • Clearer MCP errors. Design, export, and upload tools name each problem with bad input. • Delete Group. Right-click a group header in the sidebar to delete its artboards and translations. • Fixes bug where iPhone Duo screenshots could be applied to the wrong screen, or would fail when using the Capture Tool • Fixes bug where MCP connection could fail

• Apply to All Localizations: changed the source screenshot? One click in the Screen Image box now puts it on every localized version of that device, and you can undo it. • Blank artboards start with a title and subtitle: new boards begin with placeholder text sized for each format. • Improved Apple Watch templates: the watch is now sized better by default. • The Upload sheet's App, Device and Version menus now show a loading state while the App Store Connect API responds. • The custom color hex field in the Backgrounds palette keeps a fixed width, selects its value on click and ignores overlong input. • Fixes an issue where a project created with Preview Quality set to Regular opened at twice its size once the quality was High, and its exports were rejected by App Store Connect. Affected projects are converted automatically when opened, and exports now come out at document size at either quality. • Fixes a bug where "Copy Text Block to…" left the block's translations behind • Fixes a bug where text in a language set to Manual translation kept showing the original source text after the source was edited. • Fixes an issue where Add Artboard from the canvas menu added the template's iPhone instead of the device for the selected size. • Fixes a format alert when capturing an Apple Watch screenshot with the Capture Tool.

• New App Store Connect iOS size support: new iOS projects default to the updated size, and opening older iOS screenshot files will ask if you want to migrate to the new size auto-magically. Legacy versions remain available. • New App Store artwork: create and export Header, Search Results, shared artwork for both placements, and iPhone Duo screenshots. Templates coming soon. • Improved user experience: faster and more organized, with a dedicated spot for app metadata and helpful sync tools (e.g. you can now fetch individual sections from App Store Connect). You can now freely edit 3D devices right from the canvas instead of relying on the Inspector. • Improved keyboard navigation: easily move between artboards and selected localizations with your keyboard arrow keys (thanks habitoti) • Fixed an issue where opening a project with linked screenshots could create unnecessary changes in version control (new UUIDs), even when the images were unchanged. ButterKit now checks whether linked screenshots have changed before replacing them, preserving existing image IDs. (thanks u/markb) • Fixed a bug where opening the app on some screen resolutions could crash (thanks u/boulderdashed) • Added more MCP tooling, UI tweaks, and some more butter

• Showcase your app on iPhone Duo. Create screenshots with a new 3D device model and adjust the hinge angle to get the look you want. • New iPhone 18 Pro Max 3D model. Give your screenshots a fresh look with a new high fidelity model featuring realistic device materials. • Choose a cleaner device frame. Show or hide the camera cutout on iPhone Duo and iPhone 18 Pro Max to suit your design. • Add artboards more smoothly. An improved Add Artboard experience makes setting up your screenshots easier.

• Reuse styles across artboard sizes. Copy a style from iPhone to iPad, or any other artboard, to apply its background, text styling, and device appearance while keeping the right device for each artboard. Thanks to Paul on Discord! • Smoother camera transitions when animating between artboards. • More reliable Capture Tool setup. Fixed an issue that could prevent the Capture Tool from appearing, and added clearer status information in Settings > Capture Tool so you can see what’s happening as you enable it. Thanks to Moin for the help!

- Drop Shadows: Adds customizable 3D drop shadows to devices for more depth and realism. - Emoji support: Support for a wider range of emojis (e.g., ▲, ▶) when publishing to App Store Connect (thanks to Will for assisting with this) - Improved MCP for AI Agents: Improved reliability for MCP tools; large documents now fully load every artboard before agents respond, ensuring 100% accuracy for counts and design sets. Also fixes several MCP bugs and improves background MCP performance. - macOS 27: Preparation for macOS 27 and improved localization engine. - User Experience: By popular request, adds a button to show/hide the Inspector panel (thanks Franklin) - App Store Connect API: Adds ability to upload into the `DEVELOPER_REJECTED` state, which previously showed as ineligible (thanks Andrew M!) - UI improvements and bug fixes

• 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

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
