    Release Notes: Support for workers hierarchies, with a master-foremen-workers paradigm. Additionally, a worker now is able to handle more than one task at a time. Support has been added for task categories. A rule can be labeled with a category, and required computational resources (disk, memory, and CPU) can be specified per category. Makeflow then automatically communicates these requirements to the work queue or condor.

The Makeflow makeflow_log_parser now ignores comments in Makeflow logs. Work Queue supports querying workers and tasks at run-time. Makeflow Input file (dependency) renaming is supported with a new "->" operator. Work Queue Tasks are now killed using SIGKILL. Work Queue Protocol based keep-alives were added to workers.

    Release Notes: In WorkQueue, memory errors that lead to a SEGFAULT, race conditions in signal handling for workers, and incorrect handling of the -C option where a worker would not use the same catalog server as work_queue_pool were corrected. Tasks now have a unique process group to properly kill all task children on abort. Escape codes such as \n and \t are now properly interpreted in Makeflow files.
