Usually a BlackBerry Bridge update is a sign of an upcoming update to the BlackBerry PlayBook OS but I am not sure this time. RIM has updated the BlackBerry Bridge app in App World to v184.108.40.206 from the previous v220.127.116.11. That is just a tiny jump that probably just resolves a few bugs. Either way you can pick up the update directly from App World. Let us know if you spot anything!
