## What changed? The Scheduler HSM prototype now receives updates about started workflows using the callback mechanism ## Why? The original long-polling based implementation is neither necessary nor suitable for the HSM implementation. ## How did you test it? functional tests ## Potential risks None. This is experimental code. ## Documentation Added comments ## Is hotfix candidate? No
