This is release 6.4.0 of the UNICORE 6 workflow system!
It is a major release, and brings a big rewrite of the service
orchestrator. It now supports site-specific resources and allows better
pluggability of new brokering strategies. Furthermore, there are many
bug fixes and small improvements.
As usual there is a tar.gz and a jar file. For information on installation
and how to integrate with an existing UNICORE 6 installation, please refer
to the manual at
http://www.unicore.eu/documentation/manuals/unicore6/files/workflow/
or to the docs/*.txt files in the distribution.
NOTE ::: the manual also includes information on
updating a 6.3.x installation. Locally, check the
file docs/update.txt
It is unfortunately not possible to migrate data from a 6.3.x
installation.
