Corrected Bug: The function to generate minimal problems found only local minima. This has been fix. (Unfortunately for problems with many pre-allocations it may now take a very, very long time to find the global minimum... But it is possible to abort the minimizing using the menu item "Problem|Abort" or by pressing Ctrl-F4.)
Version 4.1.1.0
Corrected Bug: The current cell was not highlighted when the option "Show neighbors" was enabled. This has been fixed.
Corrected Bug: In some cases the minimization didn't find the minimized problem. This has been fixed.
Version 4.1.0.0
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.
Version 4.2.0.0
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.
Version 4.0.0.0
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.
