New Update?

Hi, ive just tried to play JO online and after clicking Play on Nova it tells me i must update before continue. Since i last played it only last nite, i went to find any info on a new update but cant find any?
I tried Update through the game and it says i have V1.3.1.15; English. As far as i can see this is the latest update?
Any ideas before i go ahead and use this auto-update.
Thanks

The current version on mine says 1.4.2.7

Thanks Bluetiereign, i used the update and its updated to 1.4.2.7 now. Just being over cautious i think.
Thanks, Dow
