This is a major release that incorporates the preview of three new tools:

• [Confuga] An active storage cluster file system built on top of Chirp. It is used as a collaborative distributed file system and as a platform for execution of scientific workflows with full data locality for all job dependencies. (Patrick Donnelly)
• [Umbrella] A tool for specifying and materializing comprehensive execution environments. Once a task is specified, Umbrella determines the minimum mechanism necessary to run it such as, direct execution, a system container, a local virtual machine, or submission to a cloud or grid environment. (Haiyan Meng).
• [Prune] A system for executing and precisely preserving scientific workflows. Collaborators can verify research results and easily extend them at a granularity determined by the user. (Peter Ivie)

This release adds several features and several bug fixes. Among them:

• [AllPairs] Support for symmetric matrices. (Haiyan Meng)
• [Chirp] Perl and python bindings. (Ben Tovar)
• [Chirp] Improvements to the job interface. (Patrick Donnelly)
• [Makeflow] Improved Graphviz's dot output. (Nate Kremer-Herman)

• [Parrot] Valgrind support. (Patrick Donnelly)
• [Resource Monitor] Library for polling resources. (Ben Tovar)
