App.json with invalid properties

Hello, it looks like, the example does not match the new igelpkg format. If I try to build it I get the following error:

Error [Parser]: Failed to validate app.json: Additional properties are not allowed ('mountpoint', 'post_mount' were unexpected)

Failed validating 'additionalProperties' in schema['properties']['rw_partition']:
    {'additionalProperties': False,
     'description': 'Definition of the optional app partition with a '
                    'persistent filesystem',
     'properties': {'backup': {'type': 'boolean'},
                    'backup_can_drop': {'items': {'type': 'string'},
                                        'type': 'array'},

     'size': 'small'}
Error [Parser]: Writable partition mountpoint must be /services_rw/supertuxkart, please remove it from the app.json, it is automatically filled in. You also need to adopt your package scripts/configuration to the new path.
Error [Parser]: It is not longer supported to specify a custom post_mount script. The script will be automatically generated based on the information from the dirs.json.

Is there a newer version available? After removing mountpoint and post_mount, the build process works.

igel-build-tools-static_1.37_amd64.deb igelpkg_0.9.22_amd64.deb
