New TCGA and TARGET Properties and Sample Type Restructuring

In GDC Data Dictionary Release 2.6.0, the GDC added support for:

• New TCGA and TARGET Properties - Several new properties and enumerated values for diagnosis, treatment, molecular tests, exposure, and pathology details for TCGA and TARGET, and other GDC supported programs
• Sample Type Restructuring - The GDC is decomposing sample type into four orthogonal properties (tissue type, tumor descriptor, specimen type, preservation method) that will improve user experience in querying for sample data
• New Workflow Types - Added new workflow types for copy number variation data
