The main distribution is a zip file. This contains the binary executable, documentation, source code and the examples.
There are minimal changes from v1.2.1. Some code has been cleaned up, including moving some variable declarations to avoid unused variable warning with some scanner configurations.
The copyright document includes a clarification that all output produced by GPLEX is the property of the user.
The distribution contains a complete VS2012 project for the application. However the latest code revisions are always available via the source code tab of this page.
Documentation is included in the zip archive, but is also available separately from this download page.
The main documentation is a single file. It now includes hyperlinked figure references, table of contents and index.
The documentation also describes the examples in the archive.
