Here are the recent changes to the packaging guidelines.
We have more things coming in concert with various distro changes that
are happening, but I wanted to get these two out there now.
The icon cache scriptlets were removed from the scriptlet guidelines, as
no live Fedora release needs them. They have been moved to the EPEL
packaging guidelines instead.
A section was added to the beginning of the guidelines, clarifying how
they apply to the various Fedora releases and to EPEL.
