Release Notes: This release introduces Tasklets, which are lightweight tasks that do not save their results to disk (but rather compute them whenever needed).
Release Notes: A new script loading mechanism was provided to better work with barrier() and the shell subcommand.
Release Notes: There is a much improved shell subcommand. jug.barrier(): stops execution if not all tasks up to that point are available. This is a "beta" release of 0.7 (whose main feature is barrier).
