- php-fints Bibliothek von 3.7.0 auf 4.0.0 aktualisiert - Parser-Fix: Ignoriert zusätzliche Bank-Felder statt Exception - HKEKA Segmente implementiert (HIEKASv5, HKEKAv5, HIEKAv5) - HKKAA Segmente implementiert (HIKAASv1, HKKAAv1) - GetStatementFromArchive und GetElectronicStatement Actions HINWEIS: HKKAA/HKEKA funktionieren noch nicht mit VR Bank (Fehler "unerwarteter Aufbau wrt DE 2" - Kontoverbindungsformat) Normale Funktionalität (Transaktionsimport) ist nicht betroffen.
