Changes between version 5.1.X and 5.2.0 of Scilab
               =================================================

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

* Visual studio uses default runtime library /MD (msvcrt.lib) to build all libraries of scilab.

* modelicac (scicos) built with Ocaml 3.11.0 on Windows

* blas, lapack, arpack libraries moved as pre-requirements (Windows)

* blas, lapack libraries moved as pre-requirements (Linux/Unix/MacOSX)

* lapack 3.2 used on Windows

Source reorganisation:
======================

* Makefile.incl.mak (Windows, dynamic link) moved from SCI directory to
  SCI/modules/src/scripts
  
* newest, get_absolute_file_path, getrelativefilename moved from io to fileio.

* bug 3668 fixed - formatnumber.f, dmdsp.f, ... moved in output_stream module.

* printf, msprintf, mprintf, print moved in output_stream module.

* disp moved in output_stream module.

* lib moved in functions module.

* oldsave, oldload functions (only used with macros of scilab 2.4) are removed
  Replaces oldsave, oldload by save and load in your code.

Input/Output functions:
=======================

 - Input arguments of fprintf are checked 

 - Rewrite :
    + getenv
    + diary

Core functions:
===============

 - Request 505 : Add error code capability to exit (SEP #19).

 - Rewrite :
     + mode
     + predef

fileio functions:
=================
  - Input arguments of functions are checked 
    (mclearerr, mclose, merror, mget, mgetstr, meof, mopen, mput, mputstr, mseek, mtell)
    
  - fileinfo manages column vector of strings (SEP #25)
  
  - basename uses fileparts

Dynamic link:
=============

 - Windows : temporary files (objects) are generated in a intermediate subdirectory (Release or Debug)
   ilib_for_link and ilib_gen_Make (with Visual studio) use a same makefile template.
   (SCI/modules/dynamic_link/src/scripts/TEMPLATE_MAKEFILE.VC)
  
 - ilib_for_link and ilib_gen_Make with lcc-win32 use a same makefile template.
   (SCI/modules/dynamic_link/src/scripts/TEMPLATE_MAKEFILE.LCC)

 - ilib_verbose (SEP #17) Set level of display returned by dynamic link functions.
 
 - add a example to call a scilab macro from a C interface
   (see SCI/modules/dynamic_link/examples/interfaces/call_scilab_function directory)
