Normally drupal.org inserts version information when a project is packaged. Git repositories do not contain this information. Git Deploy hooks into the Drupal update system and attempts to provide the version of modules and themes checked out of git.
Question arises: how to upgrade your Drupal installations * timely, * safely, * with confidence that none of your local customizations are lost; * without need to remember each line that was edited and re-applying those edits to new version; * without need to drastically change your workflow (very little discipline is needed actually); We show that Git solves those problems easily.
