A new Facebook for BlackBerry 10 release is rolling through BlackBerry World right now and looks to correct some of the timeline woes people have been having with the app as well, it adjusts according to some of the recent Facebook changes. The release is noted as being v10.4.0.14 and we've got the change log for you.
Essentially, it's the same release that was put into the BlackBerry Beta Zone previously that seems to of have gone over well enough for them to not even make any adjustments to it and just roll it out directly as soon as possible. The update should be showing in BlackBerry World right now. If not, hang tight it'll pop up soon enough.
