This morning my Vagrant Up gave me warnings about the Guest Additions not being up to date with the version of VirtualBox I'm running so I started looking for the VirtualBox Guest Additions ISO and couldn't find it on the VirtualBox website.
I did find a link to the VirtualBox download server and so easily found the VirtualBox Guest Additions ISO for the version I'm currently using.
For reference, you can access all the VirtualBox releases from http://download.virtualbox.org/virtualbox/4.3.6/.
