Comment 1 Jan Lieskovsky 2010-12-22 14:34:45 UTC

The updated (v0.2.1.28 version based) version of Tor is already present
in Fedora -testing repository. Once the prescribed testing phase is
finished, the particular packages will be pushed to -stable repository.

--

This issue affects the version of the tor package, as present within 
EPEL-5 repository.

Please schedule a rebase.
