If you're currently running the BlackBerry PlayBook OS 2.0 beta then you'll want to go ahead and check for system updates. Right now v18.104.22.16849 is currently available for download. The change log, while slim, does mention new laguages, updates to BlackBerry Bridge as well as multi-media enhancements, but that all seems rather standard plus -- it remains unchanged from previous versions. There are likely some security enhancements in there to block the DingleBerry exploit as well but, that remains to be seen as it is not specifically outlined. Go head and grab the update -- let us know what changes you're seeing.
