Hello Tom,

thanks, I missed it from the release notes.

There is a known workaround to stop execution of the flow-graph?

Thanks. Cheers,
Daniele

Sure, the patch is in current version :)

It was actually somewhat complicated to fix, though, but you could potentially cherry-pick it onto your local source. Otherwise, I don't think there is a good workaround. You'd have to have some streaming components. You could try to add a streaming port into a null sink or something stupid like that...
