4.0.5

Apr/20/12

Jasig is proud to announce the general audience release of uPortal 4.0.5. This release includes 60 bug fixes and improvements on top of the 4.0.4 release many coming from the experience of UW-Madison and other institutions going live on uPortal 4. As an overview there have been big improvements in rendering performance as well as an 80% reduction in per-user memory usage for rendered markup data via shared caching. The JSR-286 caching APIs are 100% supported and for resource requests HTTP cache control related headers are use to provide even better performance. uPortal 2/3 style fname links are now supported by the URL processor and translated into the new syntax so legacy links into your portal will remain functional. Data import performance has increased significantly and several thread-safety bugs have been resolved as well. The search portlet also has a new tabbed UI and better ability to categorize result data. As always please read through the full list below for all the details.
