do not forget update .repo after adding new playonlinux.rpm!!

it still old, can you run one command please?

[axet@axet-laptop ~]$ sudo yum install playonlinux
Loaded plugins: presto, refresh-packagekit
Setting up Install Process
Package playonlinux-3.7.1-fedora0.noarch already installed and latest version
Nothing to do
[axet@axet-laptop ~]$

there is no major difference between 3.7.1 and 3.7.2
