What's New in UniPlot 4.1.1
===========================

This page describes the changes made to UniPlot 4.1.1 since version 4.1.0.

News
----

* A new chapter :ref:`uniscript-objects` has been added to the UniScript manual.

* Almost all operators can be overloaded in the new UniScript objects (see
  :ref:`operator-overloading`).

* Waterfall Configuration:  The base value for color filling has been added to
  the waterfall configuration dialog box.

* Formula Interpreter: A new user provided callback function has been added:
  :ref:`OnFormulaFinishEval`.

Bug Fixes
---------

The following bugs have been fixed:

* Filter functions for 2D datasets: If more than one filter function was
  specified the second and all following filter functions used the original and
  not the filtered data. This bug has been fixed.

* :ref:`XYGetData`: The function call ``XYGetData(hData, 0)`` returned the
  value 0 and not as documented the original data. This bug has been fixed.

* Channel Interpolation: Channels containing ``missing_values`` could not be
  interpolated. This bug has been fixed.

* Import, Load Dataset: If a dataset in a diagram was selected the load function
  failed. This bug has been fixed.

* Style Files: The isoline values, color and pens got lost during the conversion
  of style files in the UniPlot 3.x format. This bug has been fixed.

* 2D Dataset Style: When a curve was selected the style in the toolbar combobox
  would not be selected. This bug has been fixed.

* :ref:`GetDirectory` did not return hidden files. This bug has been fixed.
  :ref:`GetDirectory` is now a uniscript function. The source code can be found
  in the :file:`script\\object.ic` file

* Objects created with :ref:`obj_create` had a problem. Some expressions could
  only be evaluated using helper variables::

     // o = obj_create()
     // o.a = obj_create()
     // o.a[1] = 123
     o = obj_create()
     o.a = obj_create()
     temp = o.a 
     temp[1] = 123
     // o = obj_create()
     // o[1] = obj_create()
     // o[1][1] = 123
     o = obj_create()
     o[1] = obj_create()
     temp = o[1]
     temp[1] = 123

  This bug has been fixed. With UniPlot 4.1.1 even the forms marked as comments
  can be used.

* UniPlot setup program: The PDSI Ini file was overwritten. This bug has been
  fixed.

* If :ref:`utf8_encode` and :ref:`utf8_decode` were invoked with an empty string
  (e.g. ``utf8_encode(strempty(1,1))``) a memory access violation occurred. 
  This bug has been fixed

* The functions :ref:`strCharToOem` and :ref:`strOemToChar` were missing.

* UniScript: If a function contains more than 255 variables UniScript caused
  and access violation. In 4.1.1 an error message is displayed.

* UniScript: UniScript files with more than 32700 lines of code could not be
  used. This bug has been fixed.

* An error in the :ref:`XYZAddIsoValues` function has been fixed.

* UniScript-Debugger: The debug window (Alt+3) did not display the right
  variables.
