+                      Scilab 5.0 Release_Notes
+                      ========================
+
+List of missing/buggy features:
+
+- Uicontrols ascendant incompatibilities:
+    * Figure size has to be increased because of the automatic insertion of
+      a menubar and the height of the docking bar.
+    * Popup uicontrols width has to be increased because of the little triangle
+      used to select a new value.
+
+- Graphics:
+    * Graphic rendering is slower in a large graphic window than in a small 
+      one.
+    * Rendering is slow or not functional on some
+      computer / graphic card / graphic card driver combination.
+      Errors often appear on Intel cards under Linux and also with 
+      old Nvidia or ATI drivers.
+    * By default arcs and circles are now approximated using a constant number 
+	  of lines.
+      To switch to real arcs, set their arc_drawing_method property to "nurbs".
+    * Sector boundary angles of arc objects are now specified in degree whereas
+	  it used to be specified in degree/64.
+    * The text_box property of text objects now refers to user coordinates even
+	  in axes_reverse mode.
+    * Bode routine creates only the two needed axes instead of four in previous
+	  versions.
+    * graypolarplot routine is now constructed using a surface instead of arcs.
+    * Some old postcript tools are not used anymore in Scilab and have been
+	  removed.
+      The list of file removed form the Scilab bin directory is:
+      BEpsf, Blatdoc, Blatdocs, Blatexpr, Blatexpr2, Blatexpr2, Blatexprs, Blpr
+	  and lpr
+    * Pixel drawing mode property of figures is not compatible with Scilab 4.
+      The result in Scilab 5 is inverted compared to the one in Scilab 4.
+      For example the result of a white object drawn above a white background
+	  in "xor" mode will appear black (it was still white in Scilab 4).
+      Moreover, the logical operators now works on the entire figure.
+      In practice, the "xor" mode can be generally replaced by the "equiv" one.      
+
+
+- It is strongly recommended to update graphic cards drivers to the latest 
+	revision:
+    * For ATI cards: http://ati.amd.com/support/driver.html
+    * For Intel cards: http://www.intel.com/support/graphics/
+    * For Matrox cards: http://www.matrox.com/graphics/en/support/drivers/
+    * For NVIDIA cards: http://www.nvidia.com/content/drivers/drivers.asp
+    * For S3 cards: http://www.s3graphics.com/en/resources/drivers/index.jsp  
+    * For SiS cards: http://www.sis.com/download/
+    * For VIA cards: http://www.viaarena.com/default.aspx?PageID=2
+
+
+- Scicos:
+    * Scicos code has been updated to the new event handling functions and code
+      (please see "Event Handling Functions" section in "CHANGES") 
+    * Tcl/Tk features are still inactive (eg. "Palette Tree")
+
+- The Scipad debugger is broken because of code reorganization that has been
+  performed in the Scilab core and rewriting of the Tcl interface. It has
+  therefore been unplugged from Scipad and will be plugged back as soon as
+  possible.
+
+- Printing can crash under Linux plateforms with recent versions of Cups.
+  See http://bugzilla.scilab.org/show_bug.cgi?id=3309
+
+- Scilab localization system is implemented, however not all the strings have
+  been added to the translation engine and therefore not translated.
+
+- Dynamic/incremental link bugs on unusual archs/compiler or with modified 
+  flags and still have issues with the binary version of Scilab.
+
+- It is not (yet, we hope) possible to build a file documentation file 
+  and add it into the documentation without rebuilding the whole documentation.
+
+- MacOS X version has some critical issues which will be probably addressed in 
+  Scilab v 5.1
+
+- The search in the help is not done on the Scicos help.
+
+- Some Linux distributions with SELinux enabled may prevent Scilab from running
+  under the default security context. Newer Linux distributions have enabled 
+  new kernel security extensions from the SELinux project at the NSA. These
+  extensions allow finer-grained control over system security. However, 
+  SELinux also changes some default system behaviors, such as shared library 
+  loading, that can be problematic to third party programs.
+
+  If you receive the error message:
+  "cannot restore segment prot after reloc: Permission denied"
+  when launching Scilab, then your SELinux configuration is preventing Scilab
+  from launching.
+
+  To rectify this issue, you can either:
+    * Change the default security context for Scilab by issuing the command:
+      chcon -t texrel_shlib_t <scilab_path>/thirdparty/java/lib/i386/server/libjvm.so
+      chcon -t texrel_shlib_t ~/flexdock/RubberBand.so
+    * Disabling SELinux altogether by setting the line
+      SELINUX=disabled
+      in your /etc/sysconfig/selinux file.
+
+  For more information about SELinux, please consult your Linux distribution
+  vendor.
