XNAT 1.9.2 and 1.8.10.4 with Container Service 3.7.0, Batch Launch 0.8.0
XNAT 1.9.2 is Now Available
XNAT 1.9.2 is a major version release, working in concert with releases of Container Service 3.7.0 and Batch Launch Plugin 0.8.0 to offer significant improvements in DICOM anonymization and import performance, container management and orchestration, and managing batch executions on systems with large amounts of data and/or processing commands enabled.
Key Updates:
Significant improvement in DICOM anonymization performance, fixing a regression introduced in XNAT 1.8.10 and surpassing previous benchmarks in speed
Role-based access to plugin administration without requiring site administration permissions
Custom labeling on compressed uploads and other UI improvements
Elimination of a notorious and intermittent XFT initialization bug and other backend improvements
The full list of improvements and bugfixes is listed in the XNAT 1.9.2 Release Notes.
XNAT 1.8.10.4 Is Also Available
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.
Key Updates:
Apply the same improvements in DICOM anonymization performance as in XNAT 1.9.2
Elimination of a notorious and intermittent XFT initialization bug and other backend improvements
The full list of improvements and bugfixes is listed in the XNAT 1.8.10.4 Release Notes.

Note for those Upgrading from XNAT 1.8.x:
Updating to XNAT 1.9.x from XNAT 1.8.x is largely the same process as before. However, due to the number of changes affecting plugins, we strongly urge you to follow all recommended safeguards, including backing up your data and performing the update in a test system with thorough QA before deploying to production.
