Summary: A focused stabilization release delivering bug fixes and stronger security hardening for production classrooms.

Added

  • Added stricter URL validation and safer resolver guardrails for indirect Student Work links.

Changed

  • Improved defensive checks around download state transitions and message-bridge handling.

Fixed

Fixed

  • Fixed early Student Work gaps where some submissions were not reachable through the normal download UX.

v1.5.0

Release 1.5.0

Summary: This is the best and most reliable state the extension has reached so far. Download buttons, flag placement, and post detection are now much more accurate in real Google Classroom usage.

Added

  • Stronger protection against bad detections and unstable page structures.

Changed

  • Download buttons are now much more careful about where they appear.

Fixed

  • Fixed random buttons appearing on Google Forms and Google Sheets links.
  • Fixed missing buttons on real Classroom attachment cards after stricter filtering.
  • Fixed duplicate or nested flag borders on some posts.
  • Fixed download states that could stay stuck even after the browser finished the file.

v1.4.0

Release 1.4.0

Summary: A major under-the-hood release that introduced the V2 engine foundation. It made the extension safer to improve without breaking the stable experience you already rely on.

Added

  • A new V2 engine foundation for smarter discovery, placement, and flag logic.
  • Better internal tooling for testing and catching regressions.

Changed

  • The extension architecture is now much more structured and ready for future upgrades.

Fixed

  • Fixed several fragile internal paths by giving the extension clearer runtime boundaries.

  • Stronger integration coverage for changelog synchronization.

Changed

  • Update detection now compares version plus changelog revision instead of version alone.
  • Popup changelog flow now force-refreshes before marking an update as seen.
