A new version of MonticelloConfigurations was added to project The Inbox:
http://source.squeak.org/inbox/MonticelloConfigurations-jr.180.mcz

==================== Summary ====================

Name: MonticelloConfigurations-jr.180
Author: jr
Time: 21 August 2022, 9:32:31.163081 pm
UUID: 3ad77782-9f0f-664c-a386-b309e153563e
Ancestors: MonticelloConfigurations-mt.179

Fix: could not copy a configuration from a directory repository to the inbox because the repositories were nil.

Actually, I did not find any UI to set the repositories of a configuration. MCConfiguationBrowser does have a #repositories: setter, but I do not see a button or menu item (or a sender method) that would invoke it.

Item was changed:
  ----- Method: MCConfiguration>>contentsOn:keyPrefix: (in category 'printing') -----
  contentsOn: aStream keyPrefix: prefix
  	"Prepend prefix to key values. If the prefix is a non-empty string, the resulting
  	key values will be ignored when parsing an original format MCConfiguration
  	from an extended format MCM file. This provides backward compatibility for
  	older images that need to read newer format MCM files."
