23892	Clarify forwards-compatibility policy for migrations	Markus Holtermann	Markus Holtermann	"We need to clarify in the documentation whether or not we are attempting to make migrations forward-compatible (that is, guarantee that it will be possible to run migrations generated on later Django versions under earlier Django versions).

Original description:

The migration operations don't accept any additional arguments (neither `*args` nor `**kwargs`). This will lead to problems in older (>=1.7) Django versions if the the migration files for 3rd party apps have been created with newer Django versions in case the new operations have a different constructor signature. Thus `**kwargs` should be added to all operation signatures.
