Hi @Centarro,
I have fixed this issue i.e. "Deprecated function: DOMDocument::createCDATASection()" and also created MR for this . Kindly review this changes .

Thank you.

Can confirm the patch works.

We need to fix the $cdata_text argument's type for the ShipStationSimpleXMLElement::addCdata() and we can provide always a string value.
Attaching the patch.

Thanks Roman, your latest patch fails as the first part of it has already been released. Updated to take this into account.
