===============================
Release Notes for PEGASUS 3.0.1
===============================
This is minor release, that fixes some bugs discovered after 3.0
release and some  enhancements. 

NEW FEATURES
--------------

1) Pegasus VM Tutorial updated

   The Pegasus VM Tutorial has been updated to use a new smaller
   Virtual Image running Debian 6 on x86. The tutorial notes are
   available online at 

   http://pegasus.isi.edu/wms/docs/3.0/tutorial_vm.php

2) pegasus-plots improvements

   The worklfow gantt chart produced by pegasus-plots now has better
   legend placement. The legends are placed below the x axis so that
   they dont interfere with the chart in the plotting area. Also the
   gantt chart generated now uses a fixed pallete of colors to assign
   colors to the different compute jobs in the workflows. Earlier,
   random colors were assigned to the compute jobs.


Bugs FIXED
----------

1) In the case where symlinking was turned on and the pool attributes
   of the source URL ( discovered in the Replica Catalog ) matched with
   the compute site, the source URL was not converted to a file URL. This
   lead to the symlink job failing when the workflow executed. This is
   fixed now and the planner now converts the source URL's used for
   symlink jobs to a file URL scheme.


2) Metrics displayed by pegasus-statistics were not clear as to what
   the worfklow execution time was, as two metrics with similar meaning
   were displayed ( Workflow Execution Time and Workflow Walltime ). The
   metrics names have been changed and the meaning of the metrics are
   explained in detail in both the output of pegasus-statistics and in
   the online user guide.

   Additional clarifications have been made to as how the metrics
   calculations happen on hierarchal worklfows.

3) pegasus-transfer when in file copy mode complained if the
   destination file already existed. This is now fixed .

4) pegasus-bug-report was broken in 3.0 release. This is now fixed.

5) Added support in pegasus-monitord for handling SUBDAG EXTERNAL jobs 
   without the DIR option.
