Full Changelog: v2026.2.1374...v2026.3.1391

[fix] DICOM anonymization
[fix] various PHP bug fixes

This release removes exiftool as the default DICOM file reader and has migrated to DCMTK. exiftool was unstable and slow. The DCMTK library is much easier to use in the back-end, so we're migrating there. Additionally, NiDB directly reads the Siemens CSA header in a single pass instead of opening a DICOM file 3 times to get all phase encoding direction tags. This significantly improves performance.

Verify that your DICOM data is archiving correctly after upgrading to this version.

[new] Use DCMTK as the primary DICOM file parser. exiftool is still used as a fallback if DCMTK is unable to open the file
[new] Use DCMTK to anonymize DICOM files
[new] update squirrel library to latest version
[new] Installers have been updated. library files are placed in /usr/lib instead of /usr/local/lib
[new] Added "keep log" option for modules
[fix] various bug fixes
[other] All references to GDCM have been removed

Install this version instead of 2026.1.1333

[fix] edge cases of exiftool failing to read DICOM files

This release removed GDCM and replaces it with exiftool (to read DICOM tags) and gdcmanon (to anonymize DICOM files). exiftool must be installed on the system. There are two workflows that might be impacted by this change:

• Archiving DICOM data
• Exporting data in NDA format -or- anonymizing exported DICOM data.

Make sure to verify that everything is working correctly for your data!

Changes for this version:
[new] Config option to enable/disable automatic backup of newly archived data
[new] Added web download option for NDA exports
[new] Switch from GDCM to exiftool to read DICOM tags
[new] Switch from GDCM to to gdcmanon to anonymized DICOM tags
[new] Added exportnonimaging module
[new] Update squirrel library, which also removed GDCM
[update] Rename installer building scripts
[fix] Search page bug, null issue, and other RHEL9 PHP bugs
