JAppRun has been replaced by launch4j. The Win32 installer has been fixed and optimized. Debian build problems for Java were fixed. Native building on Debian was disabled. A platform-independent EOL marker is used in checkfiles, which should make the checkfiles OS independent. The GUI statusbar layout has been fixed. Windows installers now include the SWT 3.3.1.1.
