REDCap 8.0

NEW FEATURES, BUG FIXES, & OTHER CHANGES:

• New feature: External Modules - External Modules are individual packages of software that can be downloaded and installed by a REDCap administrator. Modules can extend REDCap's current functionality, and can also provide customizations and enhancements for REDCap's existing behavior and appearance at the system level or project level. Modules can utilize REDCap hooks and also can have REDCap plugin pages as part of them.

• Improvement: On the Public Survey Link page in a project, a new button "Open Public Survey + Logout" has been added to increase security in case users want to open the public survey while ensuring that the participant cannot access their REDCap account in the other browser tab.

• Improvement: Thedatediff() function can now utilize the “now” variable as one of the two date/time parameters (in a similar way as the “today” variable). This is not only true for calc fields, but also for ASI logic, DQ rules, report filters, etc. You may use a time, date,datetime, or datetime_seconds field with the “now” parameter indatediff. Note: If using a date field with “now”, it will assume midnight (00:00) for the time component for the date field.

• Improvement: Fields whose values have numbers with a comma as the decimal mark (e.g., "3,14" - European number format) now work in calculated fields.
