Reverting to an old version in a branch

[M.M.]

So,if I got the point, what I should do is (x being the release number
of the current package)

* creating a new package for F-16 only, containing the latest version
compatible with such release of Fedora, with release number (x+1);
* incrementing the release number of the current package to (x+2) and
load it into the F-17, F-18 and devel branches only. (By the way,
should the changelog of this release contain also an entry for the
(x+1) release or should this be omitted?)

Is this right? Thank you.
