using 3.0.12.2366:
When configured to use Automatic Release Creation, if the “Release Creation package step” is renamed any time after configuring (and testing) ARC, the release creation process will not create new releases when the package is published to Octopus’ Nuget repo with this error in the log:
2015-08-20 10:17:28.5892 69 WARN No release created for project 'PROJECT NAME' when package PACKAGENAME version 2015.8.20.5 was pushed. No matching step could be found in the latest release.
To get ARC working again, ARC was disabled and re-configured on the project using the process step’s new name, then a release had to be manually executed; ARC did not function properly until a successful release with the correct step name was completed. After that, all future arrivals of new packages did initiate ARC successfully.
