Which version of KNIME should I recommend to clients/organizations/teams?

In the past I have been in situation where I have built a workflow in KNIME to automate a data process and later hand the workflow to someone else to run on an ongoing basis.

When doing something like this, is there a particular KNIME version I should be doing this on?

If a company already has chosen a particular version of KNIME the recommend to users in their company, then there is no choice to make, but those companies or teams within a company that don’t have a recommended version what version should I recommend?
