Although the BlackBerry Beta Zone app was only updated a few days ago, there's already a new release showing as available. It appears to only be a minor update and BlackBerry opted to not really update the change log as it shows the exact same additions as the release a few days ago. That said, there has to be an improvement in there somewhere to warrant the update so best to grab whenever you get a chance to do so. It should be showing as v10.0.0.34 if you want to sure you have the right release.
