The following command will delete all the releases from the project Web between versions 0.0.8 to 0.0.12.
octo delete-releases --project Web --minversion="0.0.8" --maxversion="0.0.12" --server http://MyOctopusServerURL.com --apikey MyAPIKey
On the example above, both minversion and maxversion will be delete as well. The complete list of releases deleted by that command will be:
0.0.8, 0.0.9, 0.0.10, 0.0.11, 0.0.12.
