 Release notes now display as a full-page postcard using the new tab page treatment, replacing the newspaper-style delivery.

 Pull requests in a GitHub stack now show their position and are grouped together in the GitHub Live Folder.

 You can right-click a Picture-in-Picture window to disable "Keep Window on Top," so it behaves like a standard window.

Dia 1.40.0 focuses on browser performance and memory.

 Re-enables Chromium's back/forward cache for instant back and forward navigations, keeping recently visited pages alive in memory instead of reloading them.

 More of your unused tabs can now be put to sleep in the background, freeing up memory so Dia stays fast and responsive.

 Your bookmarks no longer shuffle themselves around when they sync between devices.

Dia 1.36.0 sees improvements to the PiP video player as well as sync and import functionality.

 Drag a video or meeting PiP window off to the side of your screen and it sits neatly out of the way, still one click (or drag) from coming back into view. Keep your video close by, without sacrificing the screen real estate.

 Dia now imports bookmarks from Chrome's account file too, so managed and enterprise Google users bring all of them along automatically.

 We fixed a bug where tab groups could unexpectedly get deleted if you're using Sync.

Dia 1.35.0 sees performance improvements to tab closing and the bookmarks bar for a snappier overall experience.

Dia 1.34.0 sees stability and security improvements for a more reliable Dia experience.

 An architectural change to how we process web pages for various features like Memory, which improves security against malicious web page content.

 We've upgraded our Chromium engine to version 149. This is the latest stable version of Chromium as of June 2, 2026, and includes patches for a record-breaking 429 vulnerabilities.

1.33.0 tunes how Dia handles your tabs — faster when you're moving, quieter when you're not.

 Switching, closing, and jumping between tabs all feel snappier this week. We reworked how Dia tracks open tabs and moved cleanup work into the background so nothing stutters when you're in the middle of things.

 We retired a legacy display pipeline that was causing intermittent crashes on ProMotion displays. Smooth scrolling stays — the instability doesn't.

1.32.0 is a release of small bug fixes, improved reliability, and code stability. You might not notice any of the changes this week, but they're all building towards a better experience!

1.31.0 further weaves your tools through Dia, with richer third-party integrations.

 Hover over your PRs in your Github Live Group and Dia shows you CI status and any merge conflicts so you can get a rough read on how big the diff is.

 Confluence is now supported in Live Groups, so you can see the Confluence docs that need your attention alongside Notion and Gmail in your Docs Live Group.

 Tab groups now get an automatically selected emoji that represents what's inside, making them easier to scan and recognize at a glance.

 Notion mentions, comment threads, and share invites all surface in chat, so it's easier to stay caught up without context switching.

1.30.0 brings organization to the fore, with tab tidying and a redesigned overflow menu. We also added some extra analytical prowess to Dia with better file support and more accurate name recall.

 If you have 10+ tabs that haven't been touched in a while, Dia will ask if you want to clean them up. One tap and they're gone, but not gone gone—just to a temporary group before archiving.

 Dia's overflow menu got a full re-haul, helping you make sense of the sprawl. It shows open and recently closed tabs/groups, plus submenus for Chats & Files and synced devices.

Pictures (and PDFs) are worth a thousand words.

 Dia now opens and reads Slack file attachments (screenshots, images, PDFs) so no context gets lost if it's not typed out.

 Dia now pulls your real contact names instead of guessing from email addresses. Morning Brief (and every mention of attendees) will get your teammates right.

 Dia now surfaces your Google Drive notifications, like shared docs, comments, share requests. Try asking: "what's been shared with me recently?"

Dia 1.29.0 extends sync across your setup and adds a set of navigation, tab, and reliability refinements.

 Access your unpinned tabs on other devices via a section in the Tab Overflow menu.

 Dia now syncs your browser extensions, their pinned order, and enabled/disabled state across devices per-profile.

 Redesigned swipe back/forward UI replaces Chrome's arrows with a more dynamic, satisfying experience that also works on native pages.

 Shows an unread pip on closed live groups containing new items, clearing once all items are read.

 Dia's sidebar now rubber-bands when dragged beyond its max/min size, adding a polished touch inspired by Things.

 Resets selection on right-click outside the group and clarifies context menu copy for multi-tab actions.

 Clicking "Back to Tab" in Google Meet Picture-in-Picture now correctly foregrounds Dia's window.

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.

 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.

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

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

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

 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.

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

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

 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.

1.27.0 brings a quieter, faster release focused on keeping your docs front and center and trimming rough edges across settings and performance.

 A new tab group that surfaces your active Notion pages and Google Drive documents in one place, tracking comments, mentions, and collaboration activity across both tools so you never have to hunt for the doc that needs your attention.

 Fixed quadratic-time HTML-to-markdown conversion for page scraping, dramatically reducing CPU usage and battery drain on large pages.

 Removed the separate Sync preference pane, moving all sync controls under Account info for a cleaner settings experience.

 Profiles, bookmarks, and favorites now stay in sync, enabling a seamless browsing experience no matter what machine you're on.

 Upgrades the browser engine with major upstream improvements, including changes related to Chrome's Gemini integration.

 Fixes crashes during bulk delete, adds clipboard support for URLs, and introduces undo for bulk actions.

 A cleaner, more polished top bar with improved alignment, simplified visuals, and subtle selection animations.

Version 1.25.0 brings a set of thoughtful improvements to layout, visual consistency, and menu design.

 Switching between sidebar and top tabs now saves your preference across new windows and relaunches.

Improved color matching for the tab strip and URL bar.

 Color matching is now more accurate across sites like Discord, Slack, and many others where it was previously off.

 More design changes to menubar menus and context menus.

v1.24.0 brings an exciting update to how you collaborate.

 While screen sharing, you can now easily switch the tab you're sharing with a single click.

v1.23.0 turns your GitHub review cycle into satisfying moments of completion — from review to merge to what's next.

 Merging a PR or finishing a review now triggers a completion animation and feedback moment, so wrapping up feels as good as it should.

 Completed PRs clear out of your GitHub Live Group more legibly, so it's easier to see what's been tidied away.

 Hover to pull a recently completed PR back into view, so nothing you just finished gets lost.

v1.22.0 is all about meeting you where you left off — with Proactive Suggestions leading the way, faster profile switching, smarter Live Folders, and shortcuts that cut out extra steps. Here's what's new:

 Use Ctrl+1–9 to jump between profiles instantly. Click the profile indicator to see an enhanced menu with color-coded icons and shortcut hints. Profile windows switch in place — no extra windows cluttering your screen.

 Open the command bar and route directly to Chat with ⌃⌘↩ or to Google Search with ⇧⌘↩. Skip the extra step of typing and selecting.

 GitHub Live Tab Groups now update in realtime the moment you take action — merge a PR, finish a review, or close an issue — so your review queue always reflects the latest state without a manual refresh.

 When you have unsaved changes on a page and Dia's ad blocker needs to reload, you'll now get a prompt before anything refreshes — so you never lose a half-written form or comment.

 Dia can read through iframes and shadow DOMs, boosting Ask-on-Page functionality on content-rich web apps.

 We've heard some reports about Dia sluggishness and memory leaks, especially when opening new tabs. We deployed some fixes that should improve performance dramatically. If you notice any issues, please go to "Help" -> "Record Performance Issue" — it really helps us repro!

v1.21.0 is a focused update — better battery life, more visible shortcuts, and a new way to organize your sidebar. Here's what's new:

 Dia no longer prevents your Mac from sleeping when it should. A lingering resource lock in new windows has been resolved, so your machine rests when you do.

 Right-click any tab and you'll now see keyboard shortcuts next to each menu item — including any custom ones you've assigned. Less guessing, more muscle memory.

 A new setting lets you open new tabs at the top of your sidebar instead of the bottom. If your workflow starts from the top, your tabs now do too.

v1.20.0 brings split-screen browsing that finally feels like two separate workspaces, music controls that stay out of your way, and a handful of refinements that make everyday actions faster. Here's what's new:

 Hover over a pinned Spotify tab for compact playback controls — skip, pause, and play without leaving your current page. Album art fades in on hover, a subtle pulse animation responds to your system volume, and a mute indicator keeps you informed. Music stays at your fingertips, never in your way.

 In split view, each pane now has its own navigation bar and bookmark bar. Colors tint independently based on web content, the focused pane stands out, and each pane gets its own close button. Splits feel more like distinct workspaces.

 A new button in the navigation bar lets you hide or show the sidebar with a single click — no keyboard shortcut needed.

 Right-click the navigation bar or command bar with something on your clipboard. If it's a URL, you'll see "Paste and Go." If it's text, "Paste and Search." One step instead of two.

 When Dia names a tab group for you, a shimmer animation brings the label to life — a small moment of delight inspired by the command bar's tokenization effect.

 New to Dia? The command bar now surfaces helpful suggestions during your first week — like importing from another browser or logging in to Google. Never more than two at a time, and they fade away once you're settled in.

Dock "New Window" with multiple profiles.

 The macOS Dock right-click menu now shows per-profile "New Window" options when you have multiple profiles set up.

 Document Picture-in-Picture windows now display the opener tab's hostname in the top bar, so you always know which site created the floating window.

v1.19.0 introduces smarter assistance and smoother browser behavior, with AI-powered suggestions, automatic organization, and thoughtful refinements that reduce interruptions and friction. From proactive help across windows to markdown-ready links and polished visual updates, this release focuses on making Dia feel more responsive, organized, and personal. Here's what's new:

 Dia now surfaces AI-powered contextual suggestions that stay in sync across windows. Suggestions are personalized, expire intelligently, and include built-in security safeguards — helping you move faster without losing control.

 Tab Groups now receive smart, evolving names based on their content and your context. No manual naming required — your workspace stays organized automatically as it changes.

Fix for malformed markdown hyperlinks in Chat.

 Resolved an issue where the assistant occasionally generated malformed markdown links that led to 404 errors when users asked for "links."

Fix for accidental file opens from Recent Downloads.

 Dragging files from Recent Downloads now only drops them where intended, preventing them from also opening in their default macOS app.

 Creating a new window from the macOS Dock now correctly activates Dia and brings the new window to the front.

 Dia now suppresses software update prompts while you're on video calls or recording your screen or a tab — so meetings stay uninterrupted.

 You can now use ⌥⇧⌘C to copy the current page URL as a markdown-formatted link — bringing Arc's handy shortcut into Dia.

 Badges appearing and disappearing on pinned tabs now animate smoothly, adding polish and clarity to status changes.

v1.18.1 makes it easier to shape your workspace around the way you work. From more intentional Tab Groups to better window restoration and faster startup on lower-spec machines, this release focuses on keeping your setup organized, reliable, and responsive. Here's what's new:

 When you create a new Tab Group, it's automatically moved to your Pinned section. If you're grouping tabs intentionally, they stay anchored where you expect them — reducing the need to reorganize as your tab list grows.

 You can now restore an entire closed window from the File menu, including all of its tabs and Tab Groups. No digging through History or reopening tabs one by one — your setup comes back the way you left it.

A cleaner, more intentional Bookmarks Bar.

 The Bookmarks Bar now only shows Tab Groups you've explicitly closed and moved there, and only if they aren't open in another window. What you see reflects your intent, helping your workspace stay tidy.

 We corrected a tab truncation issue in the Tab Strip when Tab Groups are present, improving spacing and label clarity so your layout feels more predictable and easier to scan.

Close Tab Groups directly from the top bar.

 You can now close expanded groups without shifting your focus to the sidebar, making group management feel more natural wherever you're working.

 When Command-clicking a link while focused on a Favorite, the sidebar now scrolls to reveal the newly opened background tab — so new work doesn't get lost offscreen.

 When multiple tabs are selected, you can now copy all of their URLs in one action from the context menu — helpful when sharing research or moving work between tools.

 Bringing over your setup from Chrome is now smoother, with support for importing Tab Groups directly as bookmarks.

 Incognito windows now launch in dark mode by default, making it easier to distinguish private browsing from the rest of your workspace when switching contexts.

 Over time, large favicon caches could slow startup on systems with limited memory or slower storage. We now cap the cache at 1,000 entries — more than enough for everyday use — keeping launch times fast after the first run.

Dia v1.17.0 helps you stay on top of your work with Live Tab Groups. Here's what's new in the release:

Stay on top of PRs with Github Live Tab Groups.

 Right-click in the sidebar or tab strip to spin up a Live Tab Group that auto-populates with your Github pull requests and the PRs that need your review. As work moves forward, the folder updates itself, so your queue stays organized without manual tab wrangling.

 When your tabs overflow in the sidebar, the New Tab button now pins to the bottom so it's always within reach. You can keep opening tabs without scrolling to find the ➕.

 Dia no longer supports legacy Manifest V2 extensions.

 We've fixed issues where pinned extension icons could fail to load, accidentally drag the window when clicked, or flicker while you re-ordered them.

 Meeting reminders now behave more predictably on multi-monitor setups and alongside floating windows.

More reliable meeting related links in your tab group.

 Dia does a better job detecting and parsing meeting links when you join calls so the tabs you need open and ready.

Meeting countdowns that nudge you to wrap up.

 As you get close to the end of a meeting, the meeting tab group title now gently wiggles at the 5-minute and 2-minute marks, helping you land the conversation and move on to what's next.

v1.16.0 deepens Dia's tab story with new ways to make your workspace feel settled, organized, and tailored to how you actually work. Pin the projects that matter most, grow into Tab Groups with a familiar click, and tune tab behavior from a dedicated home in Settings. Here's what's new:

 You can now pin tab groups to the top of the sidebar or the leading edge of the tab strip.

Command‑clicking a link from a tab now opens that link in a new tab group, instead of just a standalone background tab. The original page and the new tab live together in that group, so a simple "open in new tab" gesture quietly becomes a lightweight project space.

 Option‑Command‑T now opens a new tab inside your current tab group instead of next to it so you can keep related work together.

 Tab‑related preferences now live together in a dedicated Tabs pane in Settings. Switch between sidebar and top bar layouts, and adjust Tab Group behaviors like automatic meeting grouping from one place.

Recently closed groups are easy to restore.

 When you close a tab group, it now shows up in the Recently Closed section in Tab Overflow and History menus. If you close a project group a bit too aggressively—or just want to revisit yesterday's setup—you can bring it back in a couple of clicks.

Profile indicators and menus that feel more at home.

 The profile indicator now lives more subtly inside the pinned tabs tray and sidebar header, with refined theme colors that make windows feel cohesive without shouting for attention. Context menus for empty spaces in the sidebar and top bar have also been standardized, so common actions are easier to find no matter where you right‑click.

 Making a profile your default is now a clear, first‑class action from the Profiles pane in Settings.

 Starting in v1.17, Dia will no longer supports legacy Manifest V2 extensions. With a built‑in ad blocker in place and the ecosystem moving toward Manifest V3, this keeps Dia aligned with modern extension standards and improves security and stability over time.

Dia v1.15.0 is a polish-heavy release focused on the small upgrades to the features you use every day. Here's what's new:

 Clicking Share in Picture‑in‑Picture now returns you to the Meet tab so the share dialog is accessible.

Automatic reload after turning off ad block.

 Pages now automatically reload when ad block is disabled to avoid stale content.

You can now Delete chat conversations from Chat history with the right click context menu.

 Dia now reads more structured content for channels and threads when you attach Slack to a Chat.

The New Tab Page now uses your profile color, with a theme‑colored gradient animation under the command bar that fades in and shimmers.

 Refined visuals for macOS Tahoe with polished corners and a new glass‑style app icon.
