					    FuzzME
				       List of versions
					------------
Version 2.4.6
-------------
- Fixed bug introduced in 2.4.5 - when a qualitative criterion value has been changed,
  the UI wasn't updated immediately.

Version 2.4.5
-------------
- Bug fix: when the project contains a fuzzy expert system with fuzzy rules, and the user
  changes subsequently fuzzy scales used by the fuzzy expert system, the fuzzy rules are not
  updated automatically to reflect this change and can be using the old values. To mitigate
  this issue, a new item has been added to the main menu for the fuzzy expert systems:
  "Node / Rule Base / Update fuzzy rule base after changes in the fuzzy scales".
  If you click on this menu item, the fuzzy rules are checked and updated when needed.
  Finally, the user is informed if any changes has been made by this feature.
  Use this feature, if you changed a fuzzy scale either for the fuzzy expert system
  or any of their input (the direct children of the fuzzy expert system node).

Version 2.4.4
-------------
- Options for rounding numbers are saved into the configuration file (FuzzMESettings.xml).
  By manual editing of this file, you can affect e.g. how many decimal places are used
  when exporting evaluations of the alternatives.

Version 2.4.3
-------------
- Bug fix: Problem with the Mamdani inference in cases when was there was no matching
  rule in the rule base was fixed.

Version 2.4.2
-------------
- Bug fix: Calculation of the evaluation by quantitative criterion has been fixed.
  In the previous version, an incorrect value might have been calculated in cases
  when "preference of the selected values" has been chosen as the evaluation function
  type, and, at the same time, the criterion value was fuzzy.

Version 2.4.1
-------------
- Bug fix: when a project was loaded, some decimal numbers (e.g. minimum and maximum
  possible value of a quantitative criterion) may not been parsed correctly depending
  on the selected language (an incorrect separator for decimal places was used).

Version 2.4.
-------------
- Different format for the licence file.

Version 2.3.
-------------
- New function for linguistic approximation - a warning is displayed if there are more
  linguistic descriptions that fits the evaluation in the same degree.
- Possibility to display all linguistic descriptions for the evaluations
- Support for vector graphics: the images can be saved in the SVG format,
  or in the Metapost.


Version 2.2
-------------
- Improved graphics - the fuzzy number names can contain indices (they are written in TeX notation)
- Improved graphics - the points of discontinuity of a membership function are ploted in a mathematically correct way
- Evaluation function analysis - now more characteristics can be choosen. Besides center of gravity, the user can analyse
  uncertianty, kernel, support, or both of them.
- Evaluation function analysis - the evaluation function graph can be ploted by Matlab
- Minor improvements and bug fixes


Version 2.1
-----------
- Drawing of fuzzy numbers was improved significantly. There are more possibilities to customize
  the image (ability to edit fuzzy numbers labels and set the displayed interval). Some new
  functions were added (e.g. copying to the clipboard).
- It is possible to choose which character will be used as a significant points delimiter (comma
  or space as in Matlab).
- Error logging.
- Many minor improvements and bug fixes.

Version 2.0
-----------
- support for fuzzy classification
- single-winner algorithm for fuzzy classification by the fuzzy expert system
- voting-by-multiple-fuzzy-rules algorithm for fuzzy classification by the fuzzy expert system
- ability to select AND method for the fuzzy expert system (minimum or product)
- new function: Compare the results for various inputs
- improvement: when the node type is changed from Choquet integral to fuzzy expert system, a fuzzy
  rule base will be generated according to the FNV-fuzzy measure used by the Choquet integral
- user guide added

Version 1.9
-----------
- Aggregation by fuzzified Choquet Integral added
- Aggregation by fuzzified WOWA operator added
- new function : Compare inputs and the result
- installator
- optimizations and improved speed

Version 1.8
-----------
- Gaussian and quadratic membership function for the fuzzy numbers
- faster and smoother graphic output
- improved Fuzzy Scale Editor (new dialog for creating a scale, user defined universal set, 
  clipboard operations, undo function)
- improved Fuzzy Number Editor (clipboard and file operations, undo function)

Version 1.7
-----------
- clipboard operations and drag and drop (for both nodes and alternatives)
- improvements in change node type dialog
- improvements in graphical styles (e.g. their saving and resetting)
- improvement dialog for quantitative criteria
- new inference algorithm - SugenoWOWA

Version 1.6
-----------
- improved fuzzy expert system (Else-value, Details dialog, saving and loading fuzzy rule
  base from a file, export of the fuzzy expert system into Matlab format)
- new functions for weights editation (file operations, create uniform weight, edit supports
  and kernels of the weights)


Version 1.5
-----------
- Aggregation by fuzzy OWA added
- Possibility to use one criterion multiple times in the same goals tree (link to a criterion)
- new functions in the goals tree editor (set node as the root of the goals tree, expand or
  collapse the nodes list)

Version 1.0
-----------
- The first version
