Version 3.0 supersedes version 2.0, which was released in July 2012. Installing version 3.0 will not overwrite any previous software versions. Also, version 3.0 is backward compatible, which means that any HEC-RPT project files created with previous versions are fine and ready for use with version 3.0.
Version 3.0 includes new features, improved software behaviors, and bug fixes for minor issues that were not detected prior to release of version 2.0. The User’s Manual has also been updated and is currently the most complete and comprehensive source of information about the software. Changes incorporated in version 3.0 are covered in the New Features, Improved Behaviors, and Documentation pages.
