JasperReports 4.6.0 released

JasperReports Library 4.6.0 Change Log

• improved JasperReports configuration infrastructure by the introduction of a JasperReportsContext,
  an new interface from where JR configuration properties are read and JR extensions are loaded.
  This allows different configurations of the JR engine to exist simultaneously in the same JVM;

• improved JasperReports Web Framework which now features a centralized controller to dispatch
  actions triggered by end user interactions in the report viewer. Actions are backed by atomized
  commands that modify the report metadata on-the-fly, with support for undo/redo operations,
  to reflect changes in the report output;

• introduction of reusable Web report viewer APIs, featuring configurable report viewing servlets,
  and built-in Javascript modules that can be used to create custom interactive report viewers in Web
  applications embedding the JasperReports Library.
  This is demonstrated in the new /demo/samples/webapp-repo sample where two different looking versions
  of the same build-in JR interactive report viewer are used to displays interactive reports;

• enhanced interactivity in the table component, with support for column formatting, hiding, resizing,
  moving, sorting and filtering, all leveraging the new action-based JR Web Framework controller and its
  interactivity supporting report viewer Javascript APIs;

• introduction of a data caching API that helps avoid re-querying the report's data source,
  for performance reasons, while interactively viewing the report using an interactive report viewer
  created based on the new JR Web Framework;

• added new page related events in the asynchronous report filler to support asynchronous page display
  in interactive report viewers;

• added support for message providers that can be plugged into JR as extensions, to allow
  internationalization of interactive custom components UIs;

• minor bug fixes and improvements;
