If you own a GCW Zero device you might be happy to know that there was an improvement/update for the OpenDingux OS.

Changes:

* improved video performance (enabled framebuffer caching)
* made vsync more robust (eliminated glitches on page flipping)
* made the FTP server list hidden files (names starting with a dot)
* improved Unicode support in both gmenu2x and command line tools
* fixed bug that powered off the system if the power slider was raised, released, then raised again soon after
* list IP addresses in System Info application
* added unrar command line tool
* added shared memory support (allows more applications to be ported)
