REDCap 15.0.9 Release Notes

Scheduled Upgrade Date: Wednesday, February 19, 4:45 PM – 7:00 PM (ET)

The REDCap 15.0.9 upgrade introduces new features, API enhancements, performance improvements, and eConsent 2.0. Below is a comprehensive list of changes in this release.

New Features

Longitudinal Functionality for MyCap-Enabled Projects

• MyCap now supports longitudinal projects, which were previously incompatible.

• The new MyCap mobile apps for iOS and Android fully support longitudinal projects.

• Existing MyCap projects will see a "transition" button on the MyCap Participants page for optional migration.

• The older MyCap mobile apps will remain available in the Apple App Store and Google Play Store.

New Multi-Language Management (MLM) Workflow & Enhancements

• Improved workflow and UI for adding languages to projects.

• Projects can now "subscribe" to system languages, meaning updates in the Control Center automatically apply to projects.

• New admin options for language initialization (from system languages, language files, or manual entry).

• Redesigned editing tools:

  • Separate dialogs for editing vs. updating languages.

  • Improved syncing with system languages and importing translations.

• New ASI Default Language Setting: The default ASI Language Source is now "Language Preference Field"instead of "User's or survey respondent's active language."

New Background Data Import Feature(Ideal for Large Files)

• Asynchronous data import option in the Data Import Tool.

• Imports run in the background, reducing system strain for large files.

• Users receive an email notification upon completion, including an error summary.

• If a record encounters an error, no partial data is imported, preventing corruption.

• Users can cancel imports, but already-imported data remains.

• Currently UI-only (API support may be added in the future).

eConsent 2.0 – Major Enhancements for Electronic Consent

• New "Settings for e-Consent & PDF Snapshots" page consolidates all eConsent & PDF Snapshot settings.

• Automatic PDF generation upon survey completion.

• Vault Storage Integration for long-term storage compliance.

• Multi-Form Consent Support – Combine multiple signed consents into a single PDF snapshot.

• Re-Triggering of PDF Snapshots allows authorized users to regenerate consent documents.

• Custom File Naming for Snapshots using piped variables and timestamps.

• Enhanced audit logs to track consent completion history.

API Enhancements & Connection Stability Updates

Expanded Read Replica Usage for API Exports(Prevents API Timeouts & Connection Drops)

• All API export methods now use the Read Replica database if enabled.

• Faster API response times and reduced primary database load.

Rapid Retrieval Caching for API Exports(Speeds Up Large Data Retrievals)

• API calls for Export Records and Export Reports now reuse cached results.

• Prevents excessive query execution times, reducing API timeouts.

New Background Process for Terminating Stale Queries(Prevents API Session Failures)

• A cron job now runs every few minutes to identify and terminate abandoned queries left running by API users.

• Prevents stuck API sessions that could interfere with new requests.

New "Randomize Record" API Method

• Allows API users to randomize records programmatically.

• Requires parameters: content="record", action="randomize", record=Record Name, randomization_id=Target Field/Event ID.

• Returns: Assigned randomization value or error message.

CDIS API Enhancements(FHIR Validation & New Endpoints)

• FHIR resource validation ensures only supported resources can be retrieved via API.

• New FHIR endpoints: Appointments, Procedures, Medical History, Diagnoses, Device Implants.

Future API Support for Background Data Import(Planned Enhancement)

• Currently, background data import is UI-only.

• Future API updates may allow for asynchronous data imports without API timeouts.

Performance & Usability Enhancements

✔ New Background Process for Pruning Stale Database Queries(Prevents Zombie Sessions)
✔ Survey QR Code Enhancements: Copy, download, and high-resolution SVG support.
✔ File Upload Enhancements: Full file name visibility when hovering over the download link.

✔ @MC-PARTICIPANT-JOINDATE – Captures the exact date and time a MyCap participant joins a project.
✔ @SHOWCHOICE – Restricts multiple-choice fields to only display specified choices dynamically.

New Math & Text Functions

✔ Math Functions: mod(dividend, divisor), exponential(number).
✔ String Functions: replace_text(haystack, search, replace), concat_ws(separator, text, text, ...).
