Hi, I recently upgraded a NiFi from 1.4 to 1.8 and found a breaking change. The ExecuteStreamCommand processor, in NiFi 1.5, introduced a new relationship for errors (NIFI-4559 <https://issues.apache.org/jira/browse/NIFI-4559>). The consequence: We missed that 1 of our many processors moved into an invalid state. A week later, we notice that part of our flow wasn't processing data because it's waiting for the new relationship to be drawn.
It'd be great if in the Release Notes <https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12316020&version=12341668> changes like these are highlighted under a specific section, such as "Breaking changes." Thanks Best, Ryan
