This update contains bug fixes and a few new features:

* Added a 'Previous States' tab in the DFA State Browser. It works just like the tab in the LALR State Browser.)

* Added a Nullable and First Set Table window. This information is used to construct the LALR State Table. It should be useful for students learning parsing theory.)

* The Symbol Information Window now displays relevant data. Nonterminals and terminals have different meaningful properties. The window now will only display the ones that apply to the symbol in question.)

* Fixed a bug when declaring hexadecimal set ranges. The algorithm had a flaw resulting in -1 (FFFFFFFF) in most cases.)

* Fixed a bug that affected using a Group End Terminal in productions. This should be allowed in all cases, but the system was vulnerable to the order of declaration in the grammar.)

* Fixed a bug in the Create Webpage utility. The system was duplicating group lexical information. The same text was being repeated for each group.)

Great news Devin!

I tried the Binaries Only archive (because I need to keep V4 for now as well as parallel install) but it doesn't contain the "gp.dat" file and therefore doesn't start. Is that file missing?

Thanks, Arsène
