No. The pack is not updated because some of the core mods included in it are not updated. Once new versions of those are available, the pack will most likely get updated.
For future reference, this is the thread for these discussions: http://forum.feed-the-beast.com/threads/mod-pack-update.20448
Grammar please.
Also, by that point, they should remove most of the 14.x and below packs because they aren't updated. Not very good reasoning if you ask me.
