New Feature: Option to highlight the neighbors of the current cell, available under "Options|Mark Neighbors".
Corrected Bug: The dirty flag was removed when a problem was minimized. This has been fixed.
Corrected Bug: Minimization was possible even if the problem was invalid not not resolvable. This has been fixed.
Corrected Bug: Deleting a cell value using the del-key wasn't "undoable". This has been fixed.
Corrected Bug: The severity level for X-Sudokus with 16 pre-allocated values (yes, that's possible!) wasn't displayed. This has been fixed.
New Feature: While minimizing the number of pre-allocated values of the current minimal problem is displayed.
New Feature: Sudokus with many pre-allocated values are now generated in an acceptable timeframe.
New Feature: Almost completely revised calculation of possible values. With this a major bug in calculation of the possible values for X-Sudokus has been fixed.
New Feature: It is now possible to generate "Minimized Problems", i.e., all of the pre-allocations of a generated problem are needed for an unambiguous solution. Existing problems can also be minimized by selecting the menu item "Problem|Minimize" or by pressing F9 (see also "Minimal Problems").
Corrected Bug: The menu entry "Help|Show Cell Info" was available during calculation or the generation of a new booklet. This has been fixed.
Corrected Bug: The option "Sudoku Types for Booklets" wasn't considered when creating booklet from existing problems. This has been fixed.
Corrected Bug: When exporting a problem as an html-page the filename of the problem was set to the name of the htmlfile and the "modified" flag of the problem was reset. This has been fixed.
New Feature: The calculation of the possible values for a cell has been further improved.
Corrected Bug:The date of the application's version wasn't correct (always one day in the future). This has been fixed.
New Feature: The calculation of the possible values for a cell has been enhanced (e.g., triples and quadruples are now reliable identified). From this follows that the calculated severity for some problems might differ slightly from former versions of the Sudoku game.
Corrected Bug: The "Reset" function doesn't clear any error marks. This has been fixed.
