The configuration has changed a bit. There is a new field 'type', and so-called source repositories have their own entry ('source' = collections of src.tar.gz packages). A possible bug with SSH key authentication has been fixed. Some refactoring and pylint checks have been done. There is a new feature to compare two repositories. It is possible to know which packages are absent from each repository, and version differences.
This is useful when you want to sync i686/x86_64 repositories. Comparison also works between source and binary repositories. There is a new command: get (for downloading packages).
