      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.
