This is a major release of Pegasus that introduces new advanced data handling capabilities, and contains improved support for running workflows in non-shared filesystem scenarios such as clouds and Condor pools. Pegasus now optionally separates the data staging site from the workflow execution site for more flexible data management. A new feature is PegasusLite - an autonomous lightweight execution environment to manage jobs on the compute nodes and handles data movement to/from such jobs against the workflow staging site. The RPM and Debian packages conform to the Filesystem Hierarchy Standard (FHS).
