With the last update having come back in November, Kisai Labs felt as though now was as good a time as any to go ahead and update their popular Twitter client Blaq for BlackBerry PlayBook.

You'll find this release filtering through BlackBerry World right now but in case you're not seeing it yet, sit tight. You can jump below to check out the full details and download link.
