I think it's important that varnish-2.1.0-2.fc13 is included in F-13,
and hope that it's not too late.
It was submitted by bodhi today, and can also be downloaded from koji.
Please test the update and give feedback through bodhi.
Snipped from the bodhi update request:
Details
Upgrade to new upstream release 2.1.0. This upgrade is important
because
* The previous 2.0 series will be discontinued within the
lifetime of F-13
* 2.1.0 contains a fix for CVE-2009-2936. It is not
probably that upstream will backport this fix for the
2.0 series
These changes should be important enough to include
varnish-2.1.x in F-13, even after the freeze.
