Release notes

The OnlineWebinar platform is updated regularly. Browse the release notes below for new features, performance improvements, and bug fixes to see how we’re continually enhancing your experience.

Release - 23 february 2026

New features

  • We’ve added an experimental Media over QUIC broadcaster, designed to improve video quality for users who experience stability or performance issues. This option is available now, with plans to make it the default in the future.
  • We’ve started work on an embedded webinar viewer, which will make it possible to let viewers watch webinars directly on your own website.

Improvements and bug fixes

  • Live and on-demand videos now share the same fullscreen behavior. When supported, we use the native Fullscreen API; otherwise, a fallback fullscreen mode is applied.
  • A direct link to the WebRTC connection test page is now available in the options menu of upcoming webinars.
  • We’ve added a CAPTCHA to the registration form.
  • Sentry.io error logging has been implemented to help us detect and resolve issues more quickly.

Release - 29 december 2025

New feature

  • We’re closing out the year with the possibility to add subtitles to your on-demand webinars. You can now generate subtitles after the session, whether your webinar did not have subtitles yet or you want to improve those created during the live event using more accurate post-processing.

Release - 17 december 2025

Improvement

  • Similar to a live webinar, when an on demand webinar has finished, the viewer will now see a 'Thank you for watching' message. Next to the button to return to the homepage, a button to replay the webinar is also shown.

Release - 10 december 2025

New features

  • You can now enable real-time transcription during live webinars. This new (beta) feature automatically converts spoken words into on-screen text, making your sessions more accessible and easier to follow. We’re excited about this one and can’t wait for your feedback.
  • Along with live transcription, you can now download and upload subtitle files for on-demand webinars. This makes it easy to edit, translate, or improve your captions.

Improvements and bug fixes

  • We fixed an issue where survey and exam totals were not showing correctly.
  • Chapter changes are no longer stored before starting a webinar. This prevents missing active chapters when presenters click through slides before going live.

Release - 4 november 2025

New features

  • We’re proud to share that OnlineWebinar now scores 100% on Internet.nl. This reflects our commitment to meeting the highest standards in security, modern internet technology, and digital sustainability.
  • Need to update your content? You can now upload and replace your on-demand video with ease.
    ‍
    Please note: if you use the API to upload slides or attachments, the call-definition has changed and is not backwards compatible.

Release - 23 october 2025

New features

  • You can now test your WebRTC connection on a dedicated test page. No more guesswork before going live.

New features

  • Added send follow-up email to API.
  • Pause chat scrolling when the user has scrolled up to read older messages, so the chat doesn’t immediately scrolls down when a new chat message arrives. A button is shown indicating the user has scrolled up. Clicking this button jumps to the last message again.

When clicking the ‘Take over as presenter’ button, the other presenter can continue the webinar after resuming the broadcast.
  • Added a page to display the settings for the duration of a webinar: the maximum time a webinar can start early, the maximum duration of a webinar and the available extra time. To view this page, a new option ‘Webinar duration settings’ has been added to Manage environment.

Improvements and bug fixes
