why do names of Alpha TC ISOs not contain "Alpha" anymore?

[Andre Robatino]

The names of the Alpha candidates used to contain the word "Alpha", for
example "Fedora-13-Alpha-i386-DVD.iso".  Now it's just
"Fedora-14-i386-DVD.iso", same as the Final.  Is this intentional?  I
ask because if there continue to be signed checksum files for Alpha and
Beta as well as Final, they'll all look exactly the same except for the
dates on the signatures (and most people won't even remember the release
dates in a few years).
