I just noticed this on the Zonbu site, I don’t believe it is being pushed out yet:
Version 5.797 – released 2007-08-17
- Kiosk Edition: Zonbu can be used as a secure publicly accessible Internet terminal
- Improve video driver.
- Improve monitor detection again.
- Add support for iPods formatted with iTunes 7.3.
- improve support of iPods formatted on a Mac.
- Fix a problem with Yahoo Video in Firefox.
- Fix a bug in sound preferences.
- Fix bugs in cachefs throttling algorithms.
- Printing on a Windows shared network printer does not always work.
It will be interesting to see what exactly this addresses (MPEG Playback?) and whether or not some of the things like the missing fonts reference in the Image Editor have been fixed too.
