Why Latest Version links to .zip file?

[Cesare12]

When you go to the webpage: http://archlinuxarm.org/developers/downloads

The link to the latest Raspberry Pi Version (ARMv6 Raspberry Pi at the moment) links to a mysterious zip File:
ArchLinuxARM-rpi-latest.tar.gz -> http://archlinuxarm.org/os/ArchLinuxARM-rpi-latest.zip

I think the right link should be: http://archlinuxarm.org/os/ArchLinuxARM ... est.tar.gz


Thank you for your attention.
