It's on the master mirror now.

I don't see it on other mirrors, though.

According to
https://admin.fedoraproject.org/updates/ailurus-10.07.8-2.fc13
was pushed stable, except,

{{{
$ koji list-tag-history --package=ailurus --build=ailurus-10.07.8-2.fc13

and now it's not tagged at all,
http://koji.fedoraproject.org/koji/buildinfo?buildID=187429

I'll manually tag it, should get sorted out in the next updates push. (right?)

Yes, if you manually tag it it'll go out later today.

This was done.
