Castor EDC 2019.2 release notes

Main features & improvements

Design updates

  • A new navigation menu

    • Access for Account Settings and other support links has now moved to the left side and is expandable:
      All tabs within the study and sub-tabs have also moved to the left side, which allows for more vertical space.

    • A main contact page is added, this is visible in the navigation for users that do not have manage settings rights in the study:

  • New study overview page with new functionality:

  • Studies can now be filtered using new filter options: Status, Server, Study Type and Show Archived.

  • Ability to archive studies. This can only be done by a user with 'Manage settings' rights in the study or by Castor Admins.

  • Expanded the options available to improve sorting of studies:

  • New 'Create study' page.

  • New information pages for empty Structure, Forms, Records, Reports and Surveys pages. Users are now guided through actions to set up a study in Castor and begin collecting data:

  • New loading screens added throughout the app, including a new upload animation that shows the progress of the upload:

  • Improvements for mobile compatibility for all parts of the new design.

  • More accessible interface for all parts of the new design. This means:

    • Improved usability with keyboard navigation and assistive technologies such as screen readers

    • Updated colour palettes to increase visibility for users with low-contrast vision or screens

    • Easier ways to navigate, find content and determine more easily where you are in the application

    • Improved readability of content, using clearer layouts and better font weights and sizes

Enable Two Factor Authentication at Study Level

  • Castor Admins can now set 2FA in the study admin settings, as required for the study.

  • When 2FA is enforced by the study, the user must enable 2FA in Account Settings and is required to authenticate with 2FA before accessing the study. Two factor authentication is required during login or when setting up the 2FA in Account Settings.

Large File Uploads

  • Large file uploads can be enabled for a study by a Castor Admin. The storage location for large files can only be set to a Google Cloud bucket.

  • When large file uploads are enabled, files up to 2GB in size can be uploaded using an 'Upload file' field.

  • Files can also be uploaded through the API.

  • If you are interested in using Large File Uploads, please contact us at


  • Fixed errors on the Swagger documentation page

  • New endpoint: /study/study_id/statistics, which retrieves statistics for a study. This endpoint returns total record count, institutes and record count per institute.

  • New scope has been added: study_statistics, which can be used to only grant access to the new study statistics endpoint.


  • The record export dialog now contains an option to include verifications in the export. This will include an overview of all verifications and the status of these verifications for all selected records.

Bug fixes & minor improvements

  • The status of a report that is attached to a phase is now updated directly on the phase navigator in data entry. 

  • When closing a report that was opened within another report, the previous report is still opened instead navigating the user back to the report overview. 

  • Columns of repeated measure grids can now be sorted correctly.

  • The banner which informs a user about the latest release now only shows once per release. If the user dismisses the banner, it will not be shown until the next release.

  • Apostrophes were not correctly displayed within validation messages in data entry.

  • Speed improvements when importing encrypted field values.

  • When exporting record data, uploaded files were shown as long strings in the export file. Instead of a not meaningful string, the field value is now set to --Uploaded file--

  • New icons for validations were introduced in the last release, these were only applied in data entry but not in the monitoring overview. The icons in the monitoring overview have now been updated as well.

  • Fixed an issue where error validations on fields were not removed when the value was reset.
