Version 5.0 added support for pre/post-transaction hooks and sync database file list operations. Chakra uses at the time of writing pacman 4.2.1. As more we delay as more difficult would be to keep in sync with the Arch pkgbuilds. The first thing to do is to identify if our tools can be moved to pacman 5.0. Except for hooks I don't see any other major issue. The original Allan's announce: http://allanmcrae.com/2016/01/pacman-5-0-released/
