BlackBerry Messenger 5.0.1.5 now out in beta

BlackBerry Messenger 5.0.1.5 is now available in a beta version, where most of the changes seem to be in the back end since users will hardly notice anything visually. Initial impressions are mixed, some folks claim that there is no option to adjust how both contacts and groups are displayed, while the option to accept voice notes automatically seems to be missing. As for SMS Contact integration in BlackBerry Messenger, it has apparently been worked on and we hope that this previous weakness will be come a strength in future iterations if RIM continues listening to their customers. Anyone given this version a go yet, and how do you find it?
