Beginning with XNAT 1.7.0 and running through XNAT 1.8.1 (slated for release in early April), XNAT has run on Apache Tomcat 7. As of March 31, 2021, Tomcat 7 has reached its end of life https://tomcat.apache.org/tomcat-70-eol.html. Not only will Tomcat 7 stop receiving security updates, it will be removed from the CentOS repositories in the near future. Fortunately, XNAT has already been tested against Apache Tomcat 8.5 (with some light testing on Tomcat 9 as well),…

GPU processing and AI-enabled workflows have the potential to provide massive benefits to medical image analysis and diagnosis. XNAT and NVIDIA are collaborating to incorporate XNAT's study management and containerized processing capabilities with the NVIDIA Clara healthcare application platform, and are demonstrating the fruits of that collaboration at RSNA 2019. The Clara suite of TensorFlow AI models can be trained to draw segmentations of organs and identify tumor tissue within those organs.…
This hotfix release consists solely of a fix for a security vulnerability that was reported to us by an external organization. We have addressed this issue in this hotfix, and we highly recommend XNAT administrators upgrade to this latest version of XNAT immediately.  The releases labeled "1.7.5.4" and "1.7.5.5" provided an initial fix for this issue, but were not properly tested on XNAT systems running Java 7 before release. The XNAT 1.7.5.…
