--- Comment #35 from Ankur Sinha (FranciscoD) sanjay.ankur@gmail.com --- Take a look at `fedpkg update --help`. Without any arguments, it should open up a text editor for you to fill in the template interactively. It may look at your $EDITOR environment variable to figure out what editor to use. Worth checking if that is set.
You can also use the bodhi web-interface to push updates. I prefer this for new packages because you can add all the new builds there and it'll split it into different updates for each Fedora release itself. Using `fedpkg update`, you'll have to run it for each branch manually.
