Latest release: 2026.1.2 (2026-04-30)

Next Release

Schedule

  • [Feature] In the embedded schedule widget, the session language is now shown in the session popup if the event has multiple session languages.

  • [Fixed bug] The public schedule widget and other request-path views no longer regenerate missing avatar thumbnails synchronously; regeneration is queued and the full-size avatar is served until the thumbnail is ready. This also means that schedule and speaker pages now load even when thumbnail generation is broken.

  • [Fixed bug] The calendar attachments sent to speakers on schedule release are now localised to the speaker’s preferred language, so translatable content like room names is rendered in the correct language.

General

  • [Feature] Status badges across the organiser backend and speaker area now use better contrast, improving legibility and accessibility.

  • [Feature] Password managers can now reliably associate the account’s email address with the new password when setting a password via a reset or speaker-invite link.

  • [Feature] Error pages now load the event’s custom stylesheets when an event is available on the request, so branded events keep their look on 4xx/5xx pages.

Administrators

  • [Feature] Administrators can now see when each user account was registered, both on the user list and the user detail page. For accounts created before this release, the date is reconstructed from activity logs and may not be exact. This reconstruction may take some time, depending on how many users are in your database.

  • [Announcement] Pretalx now shows a warning at manage.py check time when Pillow is installed without WebP support, so administrators are made aware that image uploads will not be processed and thumbnails will not be generated.
