XNAT 1.7.5.3 is a maintenance and bugfix release that addresses several blocker issues that were found in 1.7.5.1, and then in the 1.7.5.2 release candidate before it could be released. We recommend that any administrators using 1.7.5.1 upgrade immediately to address these issues and facilitate user workflows. 

For anyone upgrading from XNAT 1.7.4.1 or earlier, consult the XNAT 1.7.5.1 Release Notes, as each of those fixes and feature additions are included in this release.   

Download and Backend Issues Resolved 

Other backend improvements include handling of SOP classes, alias token cleanup, objects in context on session pages, and migration of protocol and internal documentation from the 1.6 branch of XNAT.  

UI Behaviors Improved

Other UI improvements include breadcrumb navigation on Project Settings page, and active-state styling of form buttons.
