This is a modest feature release. It was planned that v4.1 would include TextBroker, but that has been moved to v4.2. In this update there is one new workflow and one change to the Clone workflow.
The Clone workflow
To support some of our content promotion systems, Clone now has the option to "rename the clones". This gives each copy of the input document a new and unique name so that these copies can at some point end up in the same folder without "name collision" being a problem.
The Script workflow
This new workflow transforms an input document to and output document using a user provided script written in FTL (the same language used in templates). Refer to the workshop (week 5) and the documentation (coming) for details.
