Vuttara Browser 0.4.0

Vuttara Browser 0.4.0

Released: 2026-09-11

Vuttara Browser 0.4.0 is a larger compatibility, Windows integration, data-continuity, download, extension-isolation, and UI reliability update.

CAPTCHA and website compatibility

• Preserves and hardens Vuttara's Chromium-compatible network/runtime identity handling used by CAPTCHA and anti-bot challenge flows.
• Keeps the stable-network runtime and Chromium-compatible user-agent behavior in the compiled release.

Windows integration

• Preserves download manager reliability improvements.

Microsoft Store and installation safety

Tabs and interface

• Preserves vertical-tab context-menu, sleep/wake, overlay, and tab-management improvements.

Extensions and compatibility

• Strengthens extension packaging isolation and release verification.

Vuttara Browser 0.3.1

Vuttara Browser 0.3.1

Released: 2026-09-06

Updater reliability

• Fixed Latest found showing a stale previously downloaded version after Vuttara had already upgraded.
• Cleans obsolete downloaded updater installers and stale Ready state when the installed version is already equal to or newer than the downloaded package.
• Stores the Vuttara version associated with the last update check so an old cooldown cannot suppress the first check after upgrading.
• Tracks the newest visible release separately from installable update candidates, so an up-to-date browser still reports the correct latest published version.
• Sorts release candidates by semantic version instead of depending on GitHub API result order.
• Adds retry handling for transient network failures and HTTP 408, 425, 429, 500, 502, 503, and 504 responses.
• Manual checks use no-cache headers and a cache-busting query so a newly published release can be discovered promptly.
• Detects incomplete installer downloads before SHA-256 validation and installation.
• Prevents concurrent duplicate update checks.
• Waits for Windows to confirm the verified updater process spawned before Vuttara exits. If launching fails, Vuttara remains open and the verified package stays ready to retry.

Update control

• Vuttara still never downloads, installs, or restarts for an update without user action.
• GitHub/NSIS installations continue using Vuttara's verified GitHub updater.
• Microsoft Store installations continue using Microsoft Store-managed updates only.

Preserved 0.3.0 features

All Vuttara Browser 0.3.0 features remain included, including Vuttara AI, web AI chats, AI research tools, translation, per-site zoom, context tools, tab previews, the expanded Downloads Center, Stream Mode, installable web apps, true monitor fullscreen, performance improvements, and profile/channel isolation.

Vuttara Browser 0.3.0

Vuttara Browser 0.3.0 is a major feature update focused on AI-assisted browsing, media and multitasking, downloads, page tools, and safer side-by-side distribution through GitHub and Microsoft Store.

Vuttara AI

• Added persistent native AI conversations, chat search, pinning, renaming, export, and continuation.
• Added multi-tab AI research, source-linked tab citations, tab organization, semantic tab/history/bookmark search, screenshot and image analysis, PDF assistance, AI omnibox commands, and section-specific page analysis.
• Added automatic provider routing, Prefer Free / Prefer Local modes, provider fallback, Local AI Only, usage controls, expanded AI privacy permissions, prompt-injection filtering, and a controlled browser-action agent.
• Added an expanded Writing Assistant with tone and format transformations plus preview/replace/copy/retry controls.

Tabs, page tools, and translation

• Added element-specific page context menus with improved image, media, link, and editable-field actions.
• Added media Save As support and image tools including Google Lens / image-information actions where applicable.
• Added per-site zoom with keyboard zoom controls and persistent site-specific zoom state.
• Added page translation with Translate / Show Original controls, a toolbar action, and language settings.
• Improved duplicate-tab controls and existing tab-management behavior.
• Added tab preview cards with page thumbnails, title, URL, and tab-state information for horizontal and vertical tabs.

Stream Mode and fullscreen video

• Added Stream Mode for viewing multiple selected live tabs in a tiled browser layout without creating duplicate stream tabs.
• Added explicit Add to Stream Mode / Remove from Stream Mode controls in horizontal and vertical tab menus.
• Added safe Stream Mode audio controls including Mute All and Solo Current Tab Audio.
• Added safe handling for sleeping or recreated tabs when preparing a Stream Mode layout.
• Added true HTML video fullscreen that uses the entire monitor and hides Vuttara chrome while fullscreen is active.
• Fixed fullscreen exit so the normal browser chrome, page layout, vertical tabs, and Stream Mode layout restore correctly.

Downloads

• Expanded the Downloads Center with simultaneous-download limits, automatic queuing, priorities, Pause All / Resume All, improved filtering and sorting, progress, speed, ETA, source copying, and completed-file SHA-256 checksums.
• Preserved retry, resume, cancel, open, open-containing-folder, and duplicate-filename safety behavior.

Installed web apps

• Added Install This Site as App for supported web apps and ordinary websites.
• Added standalone Vuttara-managed app windows using the installing Vuttara profile session.
• Added Start Menu and optional Desktop shortcuts.
• Added vuttara://apps/ for launching apps, recreating shortcuts, and uninstalling installed web apps.
• Added true fullscreen support inside installed web apps.

Performance and stability

• Reduced Vuttara-side page-load overhead by caching per-site zoom lookups, batching browser-state updates, and debouncing title/favicon metadata updates.
• Improved omnibox focus/caret stability around menus and tab previews.
• Moved tab previews to a dedicated native overlay so previews no longer resize or re-layer the address-bar chrome.
• Added safer WebContents lookups around fullscreen and Stream Mode to prevent stale/sleeping tabs from causing main-process errors.

GitHub and Microsoft Store channels

• GitHub/NSIS and Microsoft Store/MSIX installs use separate single-instance locks and separate profile/data locations so both editions can be installed on the same Windows PC.
• GitHub builds continue to use Vuttara's GitHub release updater.
• Microsoft Store builds disable the GitHub application updater and use the Store-specific Updates Center instead.

Notes

Vuttara Browser remains Windows-first. The direct GitHub installer is unsigned and Windows may display an unknown-publisher or reputation warning. Microsoft Store packages are signed and distributed by Microsoft Store after certification.

Vuttara Browser 0.2.0

Important

Important for GitHub 0.1.0 users: Vuttara Browser 0.1.0 has a confirmed restart-handoff bug in its built-in GitHub updater. It can download and verify 0.2.0, but on affected installs it may close without launching the installer or reopening Vuttara. If you are on 0.1.0, manually download and run the normal Vuttara Browser 0.2.0 installer once. Your existing Vuttara profile is preserved. Vuttara 0.2.0 contains the repaired direct-updater handoff intended for future releases; the next updater transition will be tested end-to-end before publication.

Vuttara Browser 0.2.0

• New Kick and Twitch stream tabs attempt 160p once when that quality is available.
• Manual quality increases are respected after the initial automatic selection.

Tabs and omnibox

• Vertical-tabs mode no longer shows a duplicate horizontal tab strip.
• Added omnibox suggestions from open tabs, bookmarks, browsing history, prior searches, and direct search/visit actions.
• Added matching local autocomplete to the New Tab search box.
• New tabs focus/select the omnibox so typing can begin immediately.
• Fixed vertical-tab context-menu stability.
• Fixed clipped omnibox suggestions by expanding the chrome overlay while the dropdown is open.

New Tab dashboard and creator windows

• Recent sites and bookmarks.
• Compact mode.
• Restore defaults.
• Fixed slash (/) input inside dashboard customization fields.

Direct GitHub installer signing policy

Direct GitHub installers for Vuttara Browser are intentionally unsigned and will remain unsigned. Windows Security, Microsoft Defender SmartScreen, or other Windows reputation checks may display warnings for these direct-download installers because they do not carry a publisher code-signing certificate. This is expected for the GitHub distribution.

Verify the published SHA-256 checksum before installation.

Microsoft Store builds are distributed separately and are signed through Microsoft Store.

Microsoft Store

The Store/MSIX package is being handled separately and is not included in this release.
