Changes between version 5.2.X and 5.3.0 of Scilab
               =================================================


Performance:
============

* Faster access to primitive table (internal). This change improves the overall
speed of Scilab.


FFTW:
=====

* On Windows, Scilab can use FFTW3 wrapper of Intel Math Kernel Library.
  Select "Download FFTW3 wrapper optimized by Intel Math Kernel Library" during
  installation.

Graphics:
=========

* the set and get functions are now overloadable.

Documentation:
==============

* It is now possible to use LaTeX inline in the documentation. Thanks to 
 Calixte Denizet for this feature. (See bug #4329)

* bug 6630 fixed - JavaHelp does not update existing image files when 
                   building help.


Xcos:
=====

* modelica compiler 1.12.1

* bug 4156 fixed - scicos defines some temp. variables on stack without remove.

* bug 4705 fixed - scicos used a non existing file BEpsf

* The default palettes can now be manipulated by the user.

* LaTeX formulas can be used on any TextBlock using the Scilab tag based 
description.

* builnewblock.sci rewritten to use scilab dynamic link module tools.

* bug 5161 fixed - The export to SVG did not work with images or html.

* bug 5596 fixed - It was not possible to change text block properties (font
  and color)

* bug 6661 fixed - "Code Generation" menu failed.

* bug 6672 fixed - "Code generation" failed if superblock had 
                   some gain blocks.
                   
* bug 6674 fixed - modelica generic block did not work.

* bug 6668 fixed - Xcos modelica demos did not work with the new 
                   modelica compiler.

Compilation:
============

* On Windows, Pentium III class (or equivalent) with SSE instructions is 
  required.

* Windows 2000 is no more supported as operating system.

* Scilab Mac OS X distribution relies only on Java 1.6 and is therefor now
only available under 64 bits OS (Most of 10.5 and all 10.6 Mac OS X versions)

* Under Mac OS X, uses /usr/libexec/java_home instead of hardcoded paths to
  retrieve JAVA_HOME

* tclsci module is dynamically loaded by Scilab.

* pvm module is dynamically loaded by Scilab.

* fix many warnings detected by Intel Fortran 11.1.051 and more on Windows.

helptools:
==========

* %helps_modules (global variable in scilab) is defined only when 
  scilab build help and no more at scilab's startup.

Matlab to Scilab conversion tools:
==================================

* Unitary tests added.

* Matlab-Scilab equivalents dictionnary added in documentation.

* In 'mfile2sci', option only_double is now set to %T as default.

* Conversion updated with new Scilab functions:
  - 'filesep' now converted by 'filesep' instead of 'pathconvert'.
  
Tests:
======

* Mechanism of unitary tests for Java code based on TestNG added and used

Text Rendering:
===============

* Antialiasing activated by default to render text


Obsolete Functions:
===================

* 'MSDOS' obsolete see 'getos' (SEP #39).


Removed functions (previously declared as obsolete):
====================================================

* 'textprint', 'pol2tex' replaced by 'prettyprint'.

* 'tk_savefile' replaced by 'uigetfile'.

* 'tk_getdir' replaced by 'uigetdir'.

* 'tk_choose' replaced by 'x_choose'.
