Is there anything new with the Diff Update script? There hasn't been any changes in over two years. Do you still use it? https://gitorious.org/agaric-scripts/agaric-scripts/blobs/master/version-upgrade-diff.sh

I will often times have a contrib module that required patching and now needs updated to a newer version that still requires the patch(es). I was looking to modify the Diff Update script to support any d.o. project, but first wanted to hear your thoughts on the subject. I checked with the Drush project looking for a best practice in updating patched projects. They suggested managing the process via git branches. I was hoping for a solution more along the lines of the Diff Update script. https://drupal.org/node/2036737
