Version 1.74 (not yet released)
- bug fix: entering the editor and leaving the editor again without changing the level results in internal crashes of the program. In this case please switch the level up and down one time so the current level is loaded again.
- bug fix: in some cases the pushes/moves and the moves/pushes solver couldn't find the optimal solution. Thanks to Alexey for reporting this bug.
- bug fix database: the selection for levels without a collection assignment wasn't correct. This is fixed now. Thanks to Fred Minklei for reporting this bug.
- bug fix: the solver couldn't solve some levels like Thinking Rabbit Original No 10
- JSoko uses the default "Look and Feel" on Mac OS
- The new JSoko icon is used in the program
- It's possible to save a whole collection of levels in one file
- Support of "interior empty rows": a level now can contain empty lines. These "empty lines" must only contain spaces except the first character which must be a "-".
- Improved Chinese translation. Thanks to Anian Wu for this update.
- bug fix: Clicking at "Info -> about JSoko" caused an "out of memory" error. Thanks to
- optimizer: there is a new optimizing method that optimizes for:
3. box lines
4. box changes
5. pushing sessions
Optimizing for 5 metrics takes a lot more time than just optimizing moves and pushes. However, this new method can leverage all cores of a system and use more RAM as the other methods. Hence, on multi cores systems this method can be as fast as the old moves/pushes optimizing method. The results of this methods are the same as of the normal moves/pushes method except that the found solutions are also optimized for box lines, box changes and pushing sessions.
Hint: in order to use the full power of this method it's recommended to start JSoko with a higher RAM setting. The setting is in the files Start_JSoko_Linux.sh / Start_JSoko_Windows.bat
For instance the "512m" in java -Xmx512m -jar JSoko.jar can be replaced by a higher number like 5000m to allow JSoko to use 5000MB (= 5GB) RAM.
For more information have a look at the JSoko help pages.

- bug fix game: while the player has moved the moves weren't updated
- bug fix editor: setting an object on a square, then selecting another object and setting it on the same square didn't work
- bug fix optimizer: fixed drawing marked area in optimizer when not dragging from top left to lower right
- Optimizer GUI now gets scrollable when window becomes too small
- JSoko includes two new languages: Chinese and Dutch. Many thanks to Lei Zheng and Joris Wit!

- The rotation and/or flipping of the board is now represented by a new tool bar icon.
- JSoko now offers an automatic check for new versions of the program. (JSoko menu: info->search for new version at program start)
- In the graphical level browser levels having at least one solution are displayed with a check mark. Thanks to Minh Hoang for implementing that!
- If the solver is opened and then closed the main window lost the focus so it has to be clicked again to play with key board. This is fixed now.
- new feature: a new tool bar button allows to view multiple levels at once to select one for playing. Thanks to Minh Hoang for implementing that!
- When the optimizer is opened the board is set back to the initial board position in the game view. Now the board stays as it is when the optimizer is opened. Thanks to Brian Damgaard for this suggestion.
- If only a part of a solution is optimized (pushes range optimization) the displayed values during the optimization reflected the fake level created from the selected pushes range. Now the displayed values reflect the values with regard to the original level/solution. Thanks for Jean-Pierre Martel for this suggestion.
- bug fix: when the optimizer has been started for optimizing a range of the solution and a new solution has been selected during the optimizer runs the optimizer couldn't be stopped anymore by the user (however, the optimizer normally stopped after having finished the optimizing).
- bug fix: when the player is played using the key board the program crashed
- bug fix: if the level is rotated or flipped while an animation due to a selected box is displayed the animation stayed at the previous box position.
- game play: clicking at the player position now displays the reachable squares of the player
- game play: the player can be moved by click&drag. Boxes can be pushed by click&drag.
- game play: when the mouse enters the slider for browsing through the moves history the cursor turns to a hand symbol. Thanks for this suggestion to Brian Damgaard.
- bug fix: if the optimizer is used for optimizing a pushes range and iterating is enabled the optimizer can't be stopped up to the second iteration. In this version the iteration is automatically deselected when optimizing a pushes range is selected.
- bug fix: if the optimizer is used for optimizing multiple solutions at once the solutions are colored to indicate that these solutions are being optimized. In some cicumstances the last found solution stays colored after the optimizer has ended. This is fixed now.
- history slider: the history slider is now integrated in the moves/pushes display area.
- pathfinding: the menu item for switching between moves optimized pathfinding vs. pushes optimized pathfinding has been removed. There now is a button in the toolbar for switching instead.
- new feature: there is a new toolbar button for replaying a solution automatically.
- bug fix: levels that contain boxes outside the player reachable area (usually boxes and goals set there for beauty reasons) have caused a crash when the level contains a savegame/snapshot.
- new level set by David Holland
- bug fix: in huge free levels the path finding has crashed. This is fixed now.
- bug fix: if the optimizer is opened and then the another level is loaded in the game solutions couldn't be imported in the optimizer anymore.
- optimizer: competitions like the MF8 competition use rather huge levels. The optimizier can't handle these huge levels very well because in most cases there is not enough available RAM. Therefore there are two new features:
* the pushes range optimization has been changed. Example:<br>If a range from 10 to 50 is selected the solution is analyzed. All boxes that aren't pushed in this pushes range of the solution are changed to walls. Furthermore the level is changed so that the board after push 10 is taken as new start position and the board after push 50 is taken as end position. This way higher vicinity values can be used for optimizing.
* Yet, the optimizer has always tried to find improvements in all parts of a level. In order to be able of using higher optimizer settings it's now possible to mark the area that should be optimized. This is simply done by clicking or dragging in the board displayed in the optimizer (holding down the cntrl key or using the right mouse button when selecting the area will delete the marking of the selected area).<br>The optimizer then will only search for improvements in the selected area. This way it's possible to mark a really small area and then even use 3 boxes for optimizing (for instance: three boxes with a small number of vicinity squares like 6).
- bugfix: if the level is switched while the optimizer is running the optimizer has added the solution to the currently loaded level. This is fixed now.
- bugfix: if a solution is taken as new history while the solver is running the solver sometimes crashes. Now it's not possible anymore to do this.
- new feature: JSoko now supports run length format for copying a level or solution to the clipboard and loading a level / solution. Many thanks to Minh Hoang for the coding for this.
- The history slider is smaller now. Therefore showing it doesn't move the rest of the GUI too much too the left.
- bugfix: The solutions have not been ordered correctly by secondary metrics in every case. This has been fixed in this version.
- new help: JSoko now shows a help at the start of the program. Currently this help is only available in English. It's possible to open this help from the program by pressing the F1 key.
- optimizer: The optimizer offers a new check box for fixing the player end position. This is useful for players who split levels into several sub levels for better optimizing results. Thanks to Ming for suggesting this feature.
- Fixed a display problem: levels which aren't assigned to any collection have been displayed multiple times in the levels view instead of just one time. Furthermore some internal debug information have been printed to the console. These prints have been removed from the coding.
- JSoko now supports exporting a solution to the clipboard in run length format. Thanks to M. Hoang and M. Gobelli for contributing coding for this!
- New feature: in the database menu of JSoko there is a new menu item " " for importing more than one collection from the hard disk to the database of JSoko. If you have some collections you play very often you can import them to JSoko. If they are then loaded from the database JSoko will automatically save your solutions in the database, too. In the database enter the text to search for (for instance in the author text field "a*") and press enter. The GUI will then show all data that matches your input (for instance all authors whose names start with a "a"). Since version 1.49 the search is case insensitive.
- solutions sidebar: if a level has been loaded from the database the solution order is saved back to the database if changed
- workaround: due to a [http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6880336 bug] in JDK Update 18 the solvers haven't been started
- bug fix: license text for JSoko now is displayed again in about dialog
- New sidebar for displaying the solutions of a level. (feature suggestion from Jean-Pierre Martel)
- bug fix for simple deadlock detection: JSoko in rare cases falsely declared squares as deadlock squares. This resulted in false deadlock messages, false shown dead squares and let the optimizer run in an endless loop. Thanks to Sokobano for reporting this bug.
