 * <span class="label label-success">Added</span> An action is added in main toolbar to reload the VSM of installed plug-ins that may have changed. Refer to the "specifier documentation":specifier/general/Specifying_Viewpoints.html#reloadVSM for details.
 * <span class="label label-success">Added</span> In the VSM editor, when the cursor is inside an interpreted expression at a location which corresponds to a Java service invocation, hitting *F3* will navigate to the service implementation in a Java editor. See "the documentation":specifier/general/Writing_Queries.html#service_navigation for more details.
 * <span class="label label-success">Added</span> Specifier can now define a background color for a diagram representation. It is possible by specifying color in the _Background_ property section of the _Diagram Description_. Pre-defined system colors and colors from the _User Color Palette_ are supported. See "the documentation":specifier/diagrams/Diagrams.html#diagram_description for details.

 * <span class="label label-info">Modified</span> Warning: Java service throwing an @OperationCanceledException@ with a message containing the specific key word "@-RT-@" has now a specific behavior. In this case, the @OperationCanceledException@ is rethrown to rollback the command if this Java service is called from an AQL expression or through the service interpreter.
