NCI CBIIT is pleased to announce the release of caArray 2.5 and the deployment of the system at NCI CBIIT, https://array.nci.nih.gov. This release contains the following enhancements:

User enhancements

• Improved large data support
• Large datasets can now be imported together - it is no longer necessary to split large imports into smaller subsets.
• Large datasets can be uploaded easily via multiple file selection, drag and drop. (not supported in Internet Explorer)
• Audit logging of sample and data additions and deletions
• Ability to restrict access to samples based on sample characteristics
• Support for automatic refresh of experiments from caIntegrator by providing information about sample and data changes.
• Ability to configure single sign-on between caArray and caIntegrator.

Technical enhancements

• Improved file storage: Uploaded files are now stored on the file system instead of in the database.
• A plugin architecture allowing the user community to develop and deploy parsers for new data types easily.
• Major technology upgrades: Jboss 5.1, Java 6, caGrid v1.5, Struts 2.3.1.5, and NCI build-and-deploy infrastructure (NCI Nexus repository, AntHill Pro 3, BDALite).

In addition, this release includes several important bug fixes including ARRAY-1342 (A collaborator cannot see files in the "Uploaded" state even with read-write permissions to the experiment).
