dsp::ProcessorChain still supported?

Just wondering if dsp::ProcessorChain is still supported. Other than a tutorial I don’t seem to be able to find any API doc. Thanks …

Typing into the search field found it directly:
develop: ProcessorChain
master: ProcessorChain

But interestingly enough it is missing in the classes list

Thanks, yes, that’s why my question, couldn’t find it in the class list. I’m planning on using it but obviously not if its deprecated or similar.
