This changelog states changes from version 0.2

0.5 - A local MD5 implementation can now be compiled
      into the plugin so that no external library
      is needed. Should be great for embedded systems.
      MD5 might not be super-secure, but hey... it
      still takes quite some effort to break ;)
0.4 - Plugin now compiles under FreeBSD and win32.
      To compile under win32(cygwin) you have to
      make sure the openssl include directory
      is present under /usr/include/mingw/
      The plugin is not tested under win32.   
0.3 - Only some minor fixes to make the plugin work
      with olsrd 0.4.6.
      Dynamic interface removal/addition supported.
