What's New in UniPlot 5.5.0
===========================

This page describes the changes made to UniPlot 5.5.0 since version 5.4.1.

New Features
------------

* Functions for reading and writing Excel 2007 data files have been added.
  Excel 2007 doesn't need to be installed to use the new functions. Excel-2007
  sheets can contain up to 1.000.000 rows and up to 16.000 columns.

  The description of the new Excel functions is found under
  :ref:`overview-excel-files`. The new functions for writing Excel-2007 files
  can be used to create files with multiple sheets.

* Import of DIAdem TDM- and TDMS-files (see :ref:`import-export-of-tdm-files`).

* :ref:`import-of-mdf-stiegele-files` (Format of Stiegele Datensysteme GmbH and
  Caesar Datensystem GmbH).

* sqlite3 (see http://www.sqlite.org/ and :ref:`overview-sqlite`).

* PostgreSQL (see http://www.postgresql.org/ and :ref:`overview-postgresql`).

* :ref:`datadata-exchange-(page)`: More style attributes are displayed
  in the 2D-Style dialog box.

* Faster loading of documents with multiple pages. In older versions the loading
  of documents with 255 pages took approx. 5 seconds. Now the loading time take 
  less than 0.5 seconds.

* The missing_value value for NC files has been changed to 1e10. This value is
  used for floats (float 4 Bytes) and for double precision floats (double -
  8 Bytes). The old value caused problems with comparison operators.

* Improved Import Filter for CSV files, Text files, Excel files and UTX files,
  see :ref:`format-description-for-csv,-text-and-excel-files`. The obsolete
  options in the :ref:`fileimport-options` dialog box have been removed.

* The 3D Color Legend function has been modified. Instead of multiple text and
  rectangle objects the new 3D color Legend is using a table object. The 3D Color
  legend can be displayed horizontally or vertically. To create a 3D Color Legend
  right click a 3D dataset and choose 3D Legend from the context menu.
  See also :ref:`data-3d-color-legend`).

New UniScript Functions

Bug Fixes
---------

The following bugs have been fixed:

* (ID1412): If the 2D-Dataset dialog was closed using the ESC key sometimes
  the datasets on the page were not displayed. Only a replot (Alt+R) would fix
  the problem.

* (ID1435): The :ref:`fileclose-(save-compact)` command did not save the file's
  creation date. The new function :ref:`SetFileTime` fixes this problem.

* (ID1436) :ref:`@f{legendfile}`: The function changed the display order of the
  data files.

* (ID1447): The :ref:`CopyFile` and :ref:`MoveFile` can now be used with Unicode
  file names.

* (ID1456): The :ref:`fgetline` function in UniPlot 5.4.1 did handled
  0 characters differently from older UniPlot versions. 0 characters were treated
  as new line characters. Now the function will read to a "real" new line 
  character, but only return the string ending at the first 0 character.

* (ID1458): If the command **Set to Default** was used in the :ref:`toolsoptions`
  dialog box the sector size was set to 512 Bytes. Now the sector size will be
  set to 4096 Bytes. Only when running under Windows NT 4.0 is the sector size
  set to 512 Bytes.

* (ID1464): IFILE: If the maximum resolution of an IFILE was 0.025 degree
  crank angle UniPlot calculated a Crank Angle (CA) channel with a incorrect 
  resolution. The resolution was 2 times higher than specified.

* (ID1462): 2D Dataset: If a 2D dataset contained NAN's (Not a Number)
  UniPlot got stuck in an infinite loop.

* (ID1466): :ref:`ExcelRead`: If the Excel file was created by a Far East Excel
  version and the number of string was quite high the Excel file could not
  be read.

* (ID1468): :ref:`FileToField`: If the column separator occurred in quotes and
  the parameter *bQuotedNumberConversion* was set to TRUE (1) the file could not
  be read.

* (ID1471): :ref:`datadata-exchange-(page)`: If a record filter was specified
  for a NC file and a channel contained only missing_values, a script error
  occurred (:file:`DS_interface_SetDataSource.ic`, row 523).
