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.
  • Improves compatibility with sites that perform browser, challenge, login, or authorization checks.

Windows integration

  • Improves Windows taskbar identity and Vuttara launch behavior.
  • Prevents the normal development launch path from falling back to a plain Electron window.
  • Improves Default Browser integration and related Settings controls.

Downloads

  • Adds and hardens Save Download As behavior.
  • Preserves download manager reliability improvements.

Microsoft Store and installation safety

  • Microsoft Store package version is 0.4.0.0.
  • Strengthens Microsoft Store profile/data continuity when updating.
  • Keeps Microsoft Store and Direct/GitHub installations isolated so they can run side by side with separate profiles/data.
  • Release packaging explicitly excludes development extension/profile data.
  • Store package contains no VuttaraProfile, WebStoreExtensions, or workspace payload.

Tabs and interface

  • Refines the top chrome/tab spacing so the first tab starts closer to the Vuttara branding.
  • Removes runtime layout hacks that previously caused blank/chrome rendering regressions.
  • Preserves vertical-tab context-menu, sleep/wake, overlay, and tab-management improvements.

Extensions and compatibility

  • Strengthens extension packaging isolation and release verification.
  • Preserves extension authorization/popup compatibility improvements.
  • Preserves Chrome Web Store compatibility work and Vuttara's managed extension safeguards.

Streaming and browser reliability

  • Preserves streaming/media compatibility work for Kick, Twitch, and YouTube.
  • Preserves blocker/filter compatibility and browser recovery improvements.
  • Removes the unfinished Recent Kick Activity UI/polling while keeping normal Kick browser functionality.
