Thanks, but then my trial has expired. Would it be possible for me to get a pre-release to play around with?
You may get 30 days temporary license to evaluate the new version of Aspose.BarCode for C++ API once it will come out.
I’m eager to try this out. Can you share ETA since Januar is coming to an end 
I am afraid, the feature is not implemented yet in C++ library of Aspose.BarCode. Once we have an update/ETA on it, we will let you know here.
The developer told that new C++ version of the library will be implemented in 21.2 version
We are now near April and still no C++ release with Swiss. Latest is from 2019. Will it ever be released?
@bleze,
We are sorry for the delay. We are gathering information about this issue and will share our feedback at the earliest.
This is to inform you that we have fixed your issue now. We will incorporate the fix into next official release of the product (e.g. Aspose.BarCode for C++ v21.3). You will be notified here once the next release is published.
