So Workflow 8.0 was released the other day as part of ITMS 8.0
Release notes can be found here : http://www.symantec.com/docs/DOC8699
There are a few changes such as FIPS compliance, Process Manager enhancements, updates to charting libraries and a few removals but it doesn't look like a big feature release. I had been hoping for improvements such as RESTful API support but perhaps that will be in the next .1 release ;->.
Has anyone tried it yet? I'm just downloading it as part of ITMS 8.0 but these things take time.
