This release brings major improvements to the Tile layout. I redesigned the algorithm to better preserve each image’s aspect ratio while making efficient use of available space. New layout properties give you more control over how the layout behaves.

New

• Added two new templates: San Andrés, inspired by the steep streets of its namesake with a bold, vertical layout, and Studio Noir, which transforms your portraits into striking black-and-white compositions on a dark background.
• Added the new template “Tiles – Vertical” and updated “Tiles – Horizontal.”
• Introduced a new vertical layout direction for the Tile layout.

Changes

• Made several small interface refinements to the main menu, document canvas, and inspector panels.

Fixes

• The Layout > Scale Down and Scale Up commands are now active only for Square Grid layouts.
• Restored the Command–L shortcut for Layout > Method > Show All.
• The inline inspector now hides during drag operations to stay out of the way.

Fixes

• Replaced the outdated app icon in the onboarding flow.

Changes

• Added a new onboarding screen encouraging you to explore Posterino and explaining when to start your free trial.

Fixes

• The postage stamp now displays with a proper stamp-like frame.

Fixes

• Resolved duplicate layout picker items appearing in macOS 15 and earlier versions.
• Fixed an issue where Posterino would get stuck in an infinite loop while attempting to load higher resolution images.

With macOS 26 Apple introduces Liquid Glass—a visual language that blends translucency, depth, and focus across all its platforms. Posterino 6.0 embraces this design shift head-on. With Liquid Glass, controls gracefully step into the background, giving your creations more breathing room while keeping tools at hand when you need them. The result: a lighter, more refined Posterino that lets your art shine through.

A Fresher Look & Feel

• Document window redesign: Toolbars, sidebars, and split views now adapt to Liquid Glass, creating a softer, more immersive workspace.
• Canvas overlays: Zoom controls and layout actions like Scale Up and Scale Down are now integrated directly into the canvas, appearing only when relevant (e.g. Square-Grid layouts).
• Inline Inspector polish: Fully re-styled for macOS 26 with Liquid Glass, including improvements for better readability on light and dark backgrounds.
• Template picker refresh: The picker now shines in Liquid Glass and presents resolution warnings more clearly.

Streamlined Workflow

• Cleaner main menu: Updated to align with Apple’s latest Human Interface Guidelines.
• Smarter paper handling: Posterino now checks printer paper vs. document size when exporting, helping you avoid surprises before hitting “Print.”
• Focused media browser: After dropping a folder of images, the media browser now relinquishes focus automatically so you can continue working without interruptions.

Fine-Tuning & Fixes

• The selection and manipulation of graphic objects has been refined: the highlight now appears lighter, the frame handles are more elegant, and handles are shown only when an object is selected rather than when hovering over it.
• Manual layout improvements: Image drops now land where you expect them—close to the mouse pointer or properly at the origin if another image is already placed.
• Keyboard shortcuts: Layout switching no longer conflicts with system screenshot commands.
