The 5.3.3 release is a minor release to tackle two critical bugs causing :
the Japanese and Polish localizations to fail.
the Mac OS X version to fail under Mac OS X 10.6.8 following Apple last update.
New Nvidia drivers 260.xx can crash scilab (bug #7575). Workaround: You need to create a 3D graphic profile for wscilex.exe. Start Nvidia control panel --> 3d settings --> Manage 3D settings --> Add and select "wscilex.exe" for Scilab and you disable ("off") for "Threaded optimization". A warning on Scilab startup should be displayed. The latest release of the Nvidia drivers fixes this issue.
All portability issues of Scilab under Mac OS X (both 10.5 and 10.6) should be fixed. However, if any problems is encounter, please:
Some issues on startup under Mac OS X 10.6.7 (and previous 10.6 versions) have been reported. If you have "Audio Hijack" installed on your Mac OS X, it prevents some applications to work including Scilab. See bug #7012. Uninstall / disable Audio Hijack should fix this problem.
