Gentoo ppc - still supported?

I was going to download a new iso today. My old PowerPC Mac Mini needs
to be rebuilt and it's so far out of date I figured I'd just do it
from scratch. Anyway, it seems that all the other architectures have
fairly recent iso image dates while the PowerPC seems to be a year
old.

Or maybe this is just a date problem on the files or something.
