Slackware gets a lot of hate for being "outdated", but at first look, most packages aren't really any older than something like debian stable, and several like xscreensaver are much newer.
@animone if you jump to the slackware 15.0-current you will see the packages are up-to-date as in archlinux. Also grub is now as default and run each kernel upgrade, no more needed to run it manually
