Dia 1.28.0 for macOS

Macv1.28.0

1.28.0 looks the same at first glance—until you dig in a bit more. Every surface you already touch got a pass: tighter spacing, matched colors, synced preferences, and more.

  • Sidebar Visual Refresh

    The sidebar got a full polish pass: tighter spacing between tabs, cleaner group styling, and neutral-colored tab groups by default for a more minimal feel.

  • New Top Band Color Matching

    The toolbar now accurately color-matches sticky headers, so the top of your window blends seamlessly with the page beneath it.

  • Synced Settings

    Your Tabs, Privacy, Profiles, Memory, Shortcuts, and Advanced preferences now sync across devices, so every copy of Dia feels like yours.

  • Faster Tab Switching

    We removed the legacy compositor recycling system, improving tab switching performance, enabling BFCache, and simplifying future Chromium upgrades.

  • Deferred Tool Loading

    Tools now load only when the model searches for them, reducing context window size and prompt noise for faster, higher-quality responses — and making room for more tools.

  • International Domain Name Support

    Dia now decodes punycode in the address bar, command bar, hover cards, and other surfaces so international URLs display correctly.

  • Preserve Custom Tab Names in Arc Import

    The Arc-to-Dia importer now carries over custom tab names set on pinned tabs or favorites, ensuring a smoother transition for Arc users.

  • New Tab Page Query Restoration

    Navigating back to a new tab page restores your previous command bar query and selection state, so you can quickly redirect a search without retyping.
