Hello Bill!

some notes:

thanks for doing it!!!
I had some busy days trying to solve it and test properly, and with some crashes/wrong rm done I lost my work 3 times...

Today I uploaded, and noticed after the upload your NMU (sorry for overriding it, but thanks for doing it)
I had code checked out locally, and didn't even refresh browser tabs before uploading, a huge mistake on my side.

Anyway, I implemented on nlohmann-json3 a substvar variable ${nlohmann-json3-abi:Depends}, you can use on your xeus* packages, so
next release won't migrate until all reverse-dependencies are rebuilt.
I tested and forwarded the patches via email, they looks working and generating correct data. Can you please apply if possible?

thanks a lot for your work!
