Question regarding marketing module

Hi,

When will the old SuperOffice marketing template stop working?

I am quite sure I have seen som notice about that the old marketing template editor will stop shipping in some version?
But I can not find that information again.

Anyone having informatiion about this?

I have developed 3 templates long ago to a customer and need to rebuild them if they will not work anymore (10.3.3) seems ok.
Is it possible to convert them to new editor somehow or do I need to create them from scratch.
