Fresh from
the garden.

Every meaningful improvement to Sumi, from the first release onward.

Alpha

0.0.9

Download Sumi
  • Developer ToolsThe Developer Tools command and Command-Option-I open the docked Web Inspector for the active page, including a Glance preview, instead of showing instructions.
  • Restored FavoritesA restored Favorite that had navigated away from its saved address loads its current page after startup and when selected after closing another Favorite.
  • Boost loadingBoost data loads without blocking the browser, applies to pages that are already open when loading finishes, and preserves edits made during the load.
  • Storage-related stallsSession snapshots are written outside the main thread, and cached favicon reads no longer pull cold metadata from the database.

Earlier releases

0.0.8

Immediate History and Bookmarks navigation, an option to open library links in new tabs, and steadier session restoration.

Highlights

  • Immediate library navigationOpening a History or Bookmarks link in the current tab replaces the library page immediately instead of leaving it visible while the destination loads.
  • Open library links in new tabsA new General setting opens History and Bookmarks links in a new tab by default. Command-click continues to open a new tab regardless of the setting.
  • Restored-tab fallbackClosing the active tab while a restored session is still starting now loads the selected fallback tab automatically instead of leaving it cold until another click.
  • Sidebar restorationRestored sidebar visibility snaps into place at launch instead of animating after the window appears, so the loading indicator no longer slides with it.

0.0.7

First-load extension scripts, orderly permission prompts, corrected everyday browser interactions, and more consistent favicons.

Highlights

  • Extensions on the first pageContent scripts can attach to the first page of a newly opened tab without requiring a reload.
  • Permission prompt sequencingDismissing a permission prompt now settles the request and releases the sidebar so the next queued prompt can appear.
  • Settings windowCommand-W closes Settings without closing the browser tab behind it.
  • Command PaletteThe typed query no longer appears as a duplicate suggestion, and Return searches unless another result is selected.
  • Certificate trustCertificate approval remains valid for related resources in the same tab, while the URL Hub continues to show the connection as not secure.
  • FaviconsInitial and later favicon discovery use consistent ordering, raster icons resample cleanly, and repeated sidebar reads reuse the repository result.

0.0.6

More reliable downloads and webpage actions, focused Adblock rules, steadier sidebar selection, and more native browser interaction.

Highlights

  • Downloads & webpage actionsGmail attachments download correctly, and webpage context menus now have working commands for linked files, saving and copying images, and selected-text links.
  • Focused Adblock rulesHost-specific cosmetic rules run only on matching sites through the advanced pipeline. Existing compiled generations migrate locally without changing your selected filters or site exceptions.
  • Sidebar selectionSelected items scroll into view with the smallest necessary movement, while already-visible items and background opens leave the viewport alone.
  • Glance hoverPromoting a Glance preview into a tab preserves webpage hover state and the correct pointing-hand cursor.
  • Native interactionPage-top drags no longer move the browser window, handled WebKit keys no longer beep, off-screen windows return to a visible display, and collapsed sidebar hover clears cleanly.
  • Favicons & surfacesFavicons prefer appropriately sized sources, avoid uneven scaling, and reuse the canonical cache. Loading and certificate-warning surfaces follow the active appearance.

0.0.5

Locally compiled Adblock generations, bounded browser storage cleanup, and consistent site permissions across regular profiles.

Highlights

  • Unified release pathDirect downloads and Sparkle updates now use the same signed immutable DMG, while incompatible Macs remain on their last supported release.
  • Local AdblockSelected filter lists now download and compile locally into one atomic WebKit and advanced-blocking generation, while your site-specific exceptions remain intact.
  • Storage lifecycleRegular HTTP caches have a bounded budget, stale website-data and extension-controller namespaces are reclaimed safely, and regular profiles share one favicon store while private windows stay isolated.
  • Consistent site permissionsRegular-profile site decisions migrate to an install-wide scope, so the browser uses the same decision across regular profiles.
  • Quieter browser chromeSettings comes to the front reliably, certificate warnings present through the active browser surface, and sidebar hover actions, tab indicators, Space chevrons, and URL Hub popovers are more predictable.

0.0.4

More reliable redirects and external-app handoffs, continuous loading feedback, predictable Mini Player sessions, and automatic history retention that preserves website sign-ins.

Highlights

  • OAuth & external appsActive main-frame redirects can ask before opening an external app even after the original click expires, while iframe, background, Glance, and auxiliary-surface attempts remain blocked.
  • Navigation continuityThe committed page stays stable through redirect settlement and presentation URL changes, and the loading indicator no longer flashes off between short navigation chains.
  • Mini Player sessionsPlayback, mute, Picture in Picture, and dismissal stay scoped to the exact page session and window represented by each card.
  • Predictable media cardsCards remain stable after Mini Player pause or mute, activating a page does not resume it, and dismissed cards wait for a new audible playback session.
  • Sign-ins preservedAutomatic retention deletes only expired history. Website data and sign-ins remain intact, while manual website-data and cache clearing are still available.
  • Private windowsPrivate pages now resolve from their window-local ephemeral session and reliably appear in the visible compositor.

0.0.3

More reliable navigation and Glance, a redesigned Mini Player, lower fullscreen energy use, and meaningful improvements across the sidebar and Settings.

Highlights

  • Automatic GlanceEligible links from Favorites and pinned tabs can open in Glance while downloads, extension popups, modifier-clicks, middle-clicks, windows, and same-frame navigation keep their ordinary behavior.
  • Media & fullscreenLower fullscreen video energy use, more reliable native fullscreen presentation, and a redesigned multi-session Mini Player with playback, mute, Picture in Picture, focus, and dismissal controls.
  • Favorites & unloaded tabsEssentials are now Favorites, selection works across profiles, and unloaded tabs can be dimmed or desaturated from Appearance settings.
  • Sidebar reliabilityFixed tab-close hangs, favicon flicker, collapsed hover behavior, docked collapse animation, folder transitions, custom folder icons, and split-picker cleanup.
  • Search Engine settingsFilter, edit, remove, restore, and configure Tab Search engines from a clearer dedicated management surface.
  • Keyboard & extensionsUnified native command routing, toolbar search in Keyboard settings, and fixed duplicate extension context-menu items.
  • Glance lifecycleFixed navigation inside previews, teardown after closing or promotion, loading presentation, and browser link-navigation fallbacks.
  • WebKit reliabilityHardened page runtime and presentation lifecycle, fixed media context-menu downloads, and improved long-loading and notification presentation.

0.0.2

A more native, reliable Sumi with rebuilt Settings, History and Bookmarks, stronger extension workflows, and native media behavior.

Build 4 hotfix

  • Collapsed folder previewsFixed a crash when hovering a collapsed folder to open its preview. Existing 0.0.2 installations receive the fix automatically.

Highlights

  • Native Settings, History & BookmarksSettings now lives in a dedicated macOS window, while History and Bookmarks use native AppKit tables with improved editing and import/export.
  • Media & Picture in PictureBackground playback and fullscreen return to native WebKit behavior, with Picture in Picture available from the sidebar mini player.
  • Stronger extension workflowsImproved discovery, installation, activation, removal, cleanup, profile readiness, Glance support, pinning, reordering, and popup presentation.
  • A more reliable sidebarBetter collapsed interactions, scrolling, hover restoration, space transitions, favicon transitions, external-link routing, and native tab-title tooltips.
  • Safer certificate handlingA new native certificate warning flow keeps trust decisions scoped to the navigation that requested them.
  • Smoother navigationFixed restored launcher intent, file-picker activation, command-palette editing, keyboard handling, and Glance promotion flashes.
  • Automatic updatesA dedicated update channel, clearer About panel, and post-update sidebar notice prepare Sumi for reliable updates from the first release onward.

  • Privacy & Data PartitionsProfile-specific WebKit data isolation, private browsing, granular site permissions, Global Privacy Control, and content blocking bundles.
  • Safari Web ExtensionsExperimental Safari Web Extension workflows tested with Bitwarden, Proton Pass, Raindrop.io, and Userscripts.
  • Memory-aware tabsAutomatic inactive tab unloading preserves page state without consuming system memory.
