Language macros {german} and {english} gone

[Steffen Heller]

It seems that the {german} and {english} macros are gone. I recognized 5 days ago that all pages that had the macros included now only display a message "Unknown macro: english/german".

I checked the "Other macros" menu in Edit mode where you can search for all macros and there was no result when I entered "german" or "english". So it seems those macros are not not there anymore.

I contacted our IT support but haven't received a technical answer yet. So, I am trying to inquire myself. 

Can anyone tell me what has happened to those macros?
Have they been phased out globally and don't work and exist for any Confluence version anymore? Or was there some smaller change that I just need an update or something similar?

We are using Atlassian Confluence 8.5.14 and that macro is the first macro in practically all our technical document pages.

I received feedback:

"...macro is no longer compatible with the new version of Confluence..." and
"...was replaced by 'Translations for Confluence' which is a paid update and requires license..."

I searched and found a link: 
https://marketplace.atlassian.com/apps/28648/translations-for-confluence?tab=overview&hosting=server

But there is a possible next problem.
We have Confluence as Server and that that page says:

"We no longer offer sales and support for server apps. You can stay connected by exploring the migration options to either the cloud or Data Center version of this app.

Explore migration program"

What is that supposed to mean in practice?
