Warum sind diese beiden Dateien unterschiedlich?

Ich hatte die Erstere gezogen, siehe oben meinen Verweis dazu.

Nutze ich nun den zweiten Link, ist der Fehler mit dem `testing-library` weg, weil dort kein `dev-master` drin steht. Nun erhalte ich folgende Fehlermeldung:

Your requirements could not be resolved to an installable set of packages.

```auto
  Problem 1
    - Root composer.json requires oxid-esales/oxideshop-composer-plugin ^v2.0.0 -> satisfiable by oxid-esales/oxideshop-composer-plugin[v2.0.0, ..., v2.0.4].
    - oxid-esales/oxideshop-composer-plugin[v2.0.0, ..., v2.0.4] require composer-plugin-api ^1.0 -> found composer-plugin-api[2.3.0] but it does not match the constraint.
  Problem 2
    - oxid-esales/oxideshop-unified-namespace-generator v1.0.0-beta.1 requires composer-plugin-api ^1.0 -> found composer-plugin-api[2.3.0] but it does not match the constraint.
    - oxid-esales/oxideshop-unified-namespace-generator[v1.0.0-beta.2, ..., v1.0.0] require composer-plugin-api ^1.1.0 -> found composer-plugin-api[2.3.0] but it does not match the constraint.
    - Root composer.json requires oxid-esales/oxideshop-unified-namespace-generator ^1.0.0 -> satisfiable by oxid-esales/oxideshop-unified-namespace-generator[v1.0.0-beta.1, ..., v1.0.0].

```

Daher einfach jetzt meine Frage, welchen Branch oder Tags muss ich nutzen, um CE 6.0 zu installieren? Womöglich sind die beiden Verweise falsch?
