indico v3.0.rc1 Release Notes

  • 🚀 Released on June 25, 2021

    Major Features ^

    • There is a new built-in search module which provides basic search functionality out of the box, and for more advanced needs (such as full text search in uploaded files) plugins can provide their own search functionality (e.g. using ElasticSearch). (:pr:4841)
    • Categories may now contain both events and subcategories at the same time. During the upgrade to 3.0 event creation is automatically set to restricted in all categories containing subcategories in order to avoid any negative surprises which would suddenly allow random Indico users to create events in places where they couldn't do so previously. (:issue:4679, :pr:4725, :pr:4757)
    • The OAuth provider module has been re-implemented based on a more modern library (authlib). Support for the somewhat insecure implicit flow has been removed in favor of the code-with-PKCE flow. Tokens are now stored more securely as a hash instead of plaintext. For a given user/app/scope combination, only a certain amount of tokens are stored; once the limit has been reached older tokens will be discarded. The OAuth provider now exposes its metadata via a well-known URI (RFC 8414) and also has endpoints to introspect or revoke a token. (:issue:4685, :pr:4798)
    • 👉 User profile pictures (avatars) are now shown in many more places throughout Indico, such as user search results, meeting participant lists and reviewing timelines. (:issue:4625, :pr:4747, :pr:4939)

    Internationalization

    • 🆕 New locale: English (United States)
    • 🆕 New translation: Turkish

    👌 Improvements ^

    • 👉 Use a more modern search dialog when searching for users (:issue:4674, :pr:4743)
    • ➕ Add an option to refresh event person data from the underlying user when cloning an event (:issue:4750, :pr:4760)
    • ➕ Add options for attaching iCal files to complete registration and event reminder emails (:issue:1158, :pr:4780)
    • 👉 Use the new token-based URLs instead of API keys for persistent ical links and replace the calendar link widgets in category, event, session and contribution views with the more modern ones used in dashboard (:issue:4776, :pr:4801)
    • ➕ Add an option to export editables to JSON (:issue:4767, :pr:4810)
    • ➕ Add an option to export paper peer reviewing data to JSON (:issue:4767, :pr:4818)
    • Passwords are now checked against a list of breached passwords ("Have I Been Pwned") in a secure and anonymous way that does not disclose any data. If a user logs in with an insecure password, they are forced to change it before they can continue using Indico (:pr:4817)
    • Failed login attempts now trigger rate limiting to prevent brute-force attacks (:issue:1550, :pr:4817)
    • 👍 Allow filtering the "Participant Roles" page by users who have not registered for the event (:issue:4763, :pr:4822)
    • iCalendar exports now include contact data, event logo URL and, when exporting sessions/contributions, the UID of the related event. Also, only non-empty fields are exported. (:issue:4785, :issue:4586, :issue:4587, :issue:4791, :pr:4820)
    • 👍 Allow adding groups/roles as "authorized abstract submitters" (:pr:4834)
    • Direct links to (sub-)contributions in meetings using the URLs usually meant for conferences now redirect to the meeting view page (:pr:4847)
    • Use a more compact setup QR code for the mobile Indico check-in app; the latest version of the app is now required. (:pr:4844)
    • Contribution duration fields now use a widget similar to the time picker that makes selecting durations easier. (:issue:2462, :pr:4873)
    • ➕ Add new meeting themes that show sequential numbers instead of start times for contributions (:pr:4899)
    • ✂ Remove the very outdated "Compact style" theme (it's still available via the themes_legacy plugin) (:issue:4900, :pr:4899)
    • 👌 Support cloning surveys when cloning events (:issue:2045, :pr:4910)
    • 👉 Show external contribution references in conferences (:issue:4928, :pr:4933)
    • 👍 Allow changing the rating scale in abstract/paper reviewing even after reviewing started (:pr:4942)
    • 👍 Allow blacklisting email addresses for user registrations (:issue:4644, :pr:4946)

    🛠 Bugfixes ^

    • Take registrations of users who are only members of a custom event role into account on the "Participant Roles" page (:pr:4822)
    • Fail gracefully during registration import when two rows have different emails that belong to the same user (:pr:4823)
    • 👀 Restore the ability to see who's inheriting access from a parent object (:pr:4833)
    • 🛠 Fix misleading message when cancelling a booking that already started and has past occurrences that won't be cancelled (:issue:4719, :pr:4861)
    • Correctly count line breaks in length-limited abstracts (:pr:4918)
    • 🛠 Fix error when trying to access subcontributions while event is in draft mode
    • ⚡️ Update the user link in registrations when merging two users (:pr:4936)
    • 🛠 Fix error when exporting a conference timetable PDF with the option "Print abstract content of all contributions" and one of the abstracts is too big to fit in a page (:issue:4881, :pr:4955)
    • 🌲 Emails sent via the Editing module are now logged to the event log (:pr:4960)
    • 🛠 Fix error when importing event notes from another event while the target event already has a deleted note (:pr:4959)

    Internal Changes ^

    • 👍 Require Python 3.9 - older Python versions (especially Python 2.7) are no longer supported
    • confId has been changed to event_id and the corresponding URL path segments now enforce numeric data (and thus pass the id as a number instead of string)
    • 🚚 CACHE_BACKEND has been removed; Indico now always uses Redis for caching
    • 🚚 The integration with flower (celery monitoring tool) has been removed as it was not widely used, did not provide much benefit, and it is no longer compatible with the latest Celery version
    • session.user now returns the user related to the current request, regardless of whether it's coming from OAuth, a signed url or the actual session (:pr:4803)
    • Add a new check_password_secure signal that can be used to implement additional password security checks (:pr:4817)
    • ➕ Add an endpoint to let external applications stage the creation of an event with some data to be pre-filled when the user then opens the link returned by that endpoint (:pr:4628, thanks :user:adl1995)
