XNAT 1.8.10.4 Release Notes
XNAT 1.8.10.4 is a hotfix release that addresses a significant performance degradation that was uncovered during the development of XNAT 1.9.2. Knowing that much of the XNAT community is still running production systems on the XNAT 1.8.10.x line, we decided to put this remedy out on that development line.
The changes in XNAT 1.8.10.4 are strictly for backend performance and do not affect the UI, nor do they impact plugin compatibility.
We still strongly encourage XNAT system administrators to upgrade to the latest XNAT and plugin versions to receive the full benefits of using the latest code.

DE-184: Reduce reliance on regex for DICOM tag comparison to increase efficiency
Additional changes to ScriptApplicatorFactory for performance
Additionally, this release remedies a key bugfix in uploading large scans to projects with project anonymization.
