• Packit Team: Handling of Release field in propose_downstream job

  Handling of Release field in propose_downstream job # We have recently made some fixes to the process of handling the Release field regarding the %autorelease macro, so let’s take that opportunity to explain how it works. You can maintain the Release field manually, you can use a dummy value or you can take advantage of the %autorelease macro. Maintaining Release manually # You can maintain the Release field manually as you would do downstream, for example you could bump the value every time you make changes to the spec file and reset it to 1 when you release a new version.
