Release Notes: This release features built-in PDF support. A new solving technique (two-color) has been added. If you are updating from a previous release, note the change in command line syntax for specification of output file names and update your CGI scripts.
Release Notes: Two new solution techniques, "xy-wing" and "xyz-wing", have been implemented. An efficient algorithm for canonizing sudokus is now available, which is useful for archiving sudokus and checking uniqueness. Finally, a user contributed Perl CGI script has been added.
Release Notes: Apart from code cleanup and bug fixing, this release features an additional elimination technique (line-block interaction) and an improved algorithm for evaluating sudoku difficulty. SVG output has been added. PDF output is now optional, so libharu is no longer required to compile sudognu.
Release Notes: This release adds a -S option for creating sudokus with a symmetric distribution of givens.
Release Notes: This release applies the forcing chain after X-wing, swordfish, and jellyfish, improves the documentation, adds a -P option for reordering solution techniques, facilitates browsing of sudoku solutions, and adds minor bugfixes.
