TeXLive packages have been updated to the 2016 version. The most notable change is that the `biber` utility is now provided as a separate package. You can install it normally using `pacman`. Pacman hooks are now used in the TeXLive packages so the update will be less verbose than in past years. URL: https://www.archlinux.org/news/texlive-2016-packages-are-now-available/
