Changes 5.1

The Scilab Consortium would like to thank all people who helped us by reporting bugs, submiting patches, fixing bugs, testing...

New Features

Added elementary functions: acosd acot actod acoth asecd asech asec asind acsc acscd acsch csch atand cosd cotd cscd csc secd sech sec sind tand
Scicos documentation in Docbook format. PDF, PS, JAR and other versions now available.
Graphics available on all platforms and OS using function usecanvas See help page of usecanvas function for more details.
New function dae (for Differential Algebraic Equations) added. This function is providing the same features as dassl with ode (ordinary differential equations) profile. For more information, see SEP #2.
Request 564: completion add '\' or '/' at the end of a directory
Added uigetfile (Functions xgetfile and tk_getfile are now obsolete). For more information, see SEP #8.
Scilab is now supported natively under Mac OS X (See RELEASE_NOTES_5.1.X)
Uses termios instead of termio in NW & NWNI modes

Enhancement

Graphics stabilty improved.
Graphics speed improved.
Menubar/toolbar update improved (particularly when (un)docking windows).
Update of some output strings (standard, warning & error)
Scilab uses Atlas 3.9.4 on Windows
Directive FRENCH IMPOSED added to test_run() to force the test in french
Errors occuring when getting or setting graphic/gui handles properties are now treated as any other Scilab errors.
Now catch the exception when JOGL is crashing because native library gluegen-rt is not available in the java.library.path (LD_LIBRARY_PATH) and display a nice message
Better error report in the documentation build process (docbook)
Binary versions embed jre 1.6.0_11
test_run() now accepts absolute paths as first input argument. It permits toolboxes to use this system.
Under Linux/Unix, do not launch Scilab in background when called without argument
icons are now installed into pkgdatadir/icons/
Update of the example in the dynamic_link modules and in the toolbox skeleton (use the actual filename instead of the .o)

Tests

Tests added for functions: umf_luget, taucs_chget, pcg, removedir, rmdir, ones

Misc

Some dead code removed (SCI/scripts/, SCI/bin/{dold,scilink,Blatdoc,Blatdocs,f77-linux,minfopr} )

Compilation

libmatio is now detected thanks to pkg-config
More warnings in C/C++/Fortran during the compilation process. See http://lists.scilab.org/cgi-bin/ezmlm-browse?list=dev&cmd=showmsg&msgnum=684
--enable-build-help is now the default behaviour (--disable-build-help removes the check of the dependencies)
--with-fftw, --with-pvm and --with-umfpack are now the default behaviour (--without-fftw, --without-pvm and --without-umfpack removes their builds)
interpolation, signal_processing, statistics modules are loaded dynamically by Scilab.
cc and cc-* are not longer consider as GNU C compiler when detecting the compiler (use gcc & gcc-*) because it was causing some issues under Solaris
By default, under Linux/Unix/Macosx, static libraries are no longer built.
Do not init TK when building the doc ("make doc")... in order to be able to build Scilab through ssh
Giws has lost it .py extension
Force the build for the french documentation.
