mehalter [1] filed a orphan request for tmuxinator [2]: This package updated a couple weeks ago and the previous version isn't compatible with the newest version of tmux. I contacted the maintainer and haven't heard anything back. I am happy to pick up on maintaining the package, and can update the PKGBUILD [1] https://aur.archlinux.org/account/mehalter/ [2] https://aur.archlinux.org/pkgbase/tmuxinator/
