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

  • [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.
