Generally speaking... If you update to a development branch, you may need to reparse your files in order to see bug fixes and new features in action. We put in an update hook (as needed) when we make a release that will mark necessary files for reparsing, but we don't do that with each change in a development branch. (You can use Drush commands or the admin interface to mark various branches for reparsing.)
