--- upgrade: - | The remote debugger has been removed from the codebase. If you were using it, you will need to find an alternative solution. The remote debugger was un-maintained and was first introduced in the early days of OpenStack when we used python 2.7. While it was useful at the time, it has not been maintained and updated to work with new versions of python and eventlet. As a result it is being removed until we complete the eventlet removal.
