The release version still can be found in /releases/13/Everything and the final version in /updates/13 of the
download server/mirrors. The final version still can be installed with yum, too.
Code:
su
yum install wine
It also can be compiled from source available from
winehq.org. It's an easy one to compile if you have the devels and libs it needs installed.
WineHQ has a script that will install those in Fedora.
P.S.: Moved to EOL (End of Life) Versions.
