This is a minor GUI improvement and performance enhancement release. Features of this release include:
- Improved default hanging protocols for all modalities. 
NOTE: Default hanging protocols now assume two monitors with 2x2 viewports in each monitor. This behavior can be modified in Tools > Options > Layout, Tools > Options > Layout > Display sets, and through the Hanging Protocol manager.
. - An option is available to use the number keys 3 through 8 to select window/level defaults, rather than series
 - SUV measurements are now calculated by body weight only by default
 - Measurements and ROIs may be drawn with a single click and drag (rather than requiring a click to release)
 - The time delay for transforming a left-click with the stack tool into a probe/measurement tool has been decreased (to facilitate quick measurements without changing from the stack tool)
 - An ellipse annotation tool has been added
 - The ability to import and export specific hanging protocols has been added (rather than requiring an all-or-nothing import/export)
 - Stacking speed of mammography tomographic images has been improved
 - Numerous minor performance enhancements and user interface tweaks
