[MapProxy] OSM-Tiles in MapProxy 1.4

["Jäger, Frank (KRZ)"]

Hallo,
I have an MapProxy 1.1.2 running about a year.
Now all has to move to a new machine. I installed a MapProxy 1.4 as 'multiapp' and tried to use parts of the old configuration. 

It caches some OpenStreetMap-Tiles für local use as WMS.
This doesn't work on 1.4. I get only a blue background (see ?).


* base.yaml *
-------------

grids:
  global_mercator_osm:
    base: GLOBAL_MERCATOR
    num_levels: 19
    origin: nw


* projects/osm_mapnik.yaml *
----------------------------

services:
  wms:
    srs: ['EPSG:4326', 'EPSG:25832', 'EPSG:31467', 'EPSG:54004']
layers:
  - name: mapnik
    title: Mapnik
    sources: [osm_mapnik_c]
caches:
  osm_mapnik_c:
    grids: [global_mercator_osm]
    sources: [osm_mapnik_tile]
sources:
  osm_mapnik_tile:
    type: tile
    url: http://a.tile.openstreetmap.org/%(tms_path)s.png
    #origin: nw
    coverage:
      bbox: "451000,5737000,525000,5822000"
      bbox_srs: "EPSG:25832"

**

The "origin"-Option has moved from "sources" to "grids".
What else must change from MapProxy Vers. 1.1. to 1.4 to get it work?
