Is ZUGFeRD 2.1 still valid?

[Luis Casanova]

Hello group,

with ZUGFeRD 2.3 already available, I read that ZUGFeRD 2.2 will stop being supported by September 2025.

I have a customer that only accepts ZUGFeRD 2.1 invoices and that is preventing me from upgrading to ZUGFeRD 2.3. 

So I would like to know, is 2.1 still a valid version?

What could be the issues that I can face if I choose not to move to ZUGFeRD 2.3.

Thanks in advance!

Hi,

> I read that ZUGFeRD 2.2 will stop being supported by September 2025.

Where did you read that? 

I hear that for the first time and it's not true, AFAIK there will (hopefully) be a communication to finally deprecate ZUGFeRD 1.0 first.
