The role of the FAST software repository has evolved over the past few years, and it is time to rethink what the goal of FAST is. See Rethinking the goal of FAST for some perspective about FAST. The upshot is that FAST has been reorganized to support an ensemble of independent software packages related to agile software development.
One important change in this reorganization has been the decomposition of the FAST Python software into independent components. Some elements of FAST are deprecated, and the rest have been spread out into various packages. See the FAST Blog for further details.
