I am a bit reluctant to pull in a major update into a stable tree.
2.1.8 has been built for fedora-devel for some time, and I think it will install
cleanly on FC6, too.

I'd be grateful if you could try it out and see how it goes.

Using yum from the command line this will get you going, if you already have the
FC6 version installed:

yum --enablerepo extras-development upgrade \*fwbuilder\*

Now that Fedora 7 is out.  And you have FWbuilder 2.1.10 in F7, FWbuilder 2.1.12
has now been released:) 

There is a 2.1.12 package in rawhide right now, if noone complains I'll build it
for F7, too.

With updates-testing for F7, you can build it for F7, too, without causing
trouble. You have to mark the build as stable in Bodhi, before it gets into the
stable repo.
