Castor EDC 2019.1 release notes

Main features & improvements


  • Encryption will be available as a premium feature and can be enabled in the study settings. More information around the entire feature can be found in the relevant manual section.


  • It is now possible to copy survey packages. When copying survey packages the following is copied: Intro text, outro text, settings and the selection of surveys within the package.

  • The export and import of study structure now also includes survey packages. Survey packages will always be exported/imported with their associated surveys. Thus, importing a survey package in a new study will import the associated surveys.

Option groups

  • Option groups with up to 15000 options can be imported via a csv file upload.


  • It is no longer possible to edit option groups that are used in fields that are in use as randomization strata.

  • It is no longer possible to edit or delete fields, steps or phases that contain randomization strata. 

  • Randomization is now disabled for records with an exclusion

  • A user with only randomization rights (not view randomization) can now view ‘Randomized by’ and ‘Randomized on’ in the randomization tab. 


  • In the main reports overview you can now double click the report and you will be taken to the report in data entry view. 

User management

  • The user management grid now shows which users have two factor authentication enabled. The rights overview print functionality also shows this.

Bug fixes & small improvements

  • When a user adds more than 50 fields or more than 10 calculation fields in a step, a warning message appears at the top of the step warning the user that this can negatively impact the performance.  This means that if you are using more than the suggested amount of fields in one step, a slower loading of steps and fields in data entry is to be expected.

  • Validation messages in data entry are updated and have new colours.

  • The ‘Show reports’ toggle in data entry above the phase navigator is now only available when there are reports attached to phases. 

  • When editing an existing automation that creates or sends a survey package, an error appeared when saving the automation without opening the action dialog. This has been fixed.

  • Fixed the randomization block size dropdown that could not be changed after saving a value.

  • Fixed report-instance-collection endpoints that returned an error for POST requests.
