Changelog

v1.1.1 (2026-03-05)

Bug fixes

Fixed compatibility with Moodle App and Microsoft Teams webview (#8).
- Document preview now works in the Moodle App: the viewer page loads with
  direct iframe rendering (no blob URLs) for webview compatibility.
- The download button now uses a server-side forced download (Content-Disposition: attachment) instead of the HTML download attribute, which is unreliable in
  webviews and caused the "index.php" filename issue.
- The JS link interceptor on course pages is skipped in the Moodle App, since
  the app renders course content natively.
