Package: libjson-xs-perl Version: 3.030-1 Severity: important 3.0 (released 2013) removed to_json/from_json with no further information given (https://sources.debian.net/src/libjson-xs-perl/3.030-1/Changes/#L40)
This seems to break a documented interface of libjson-perl's if installed. I don't know the full history but it seems that there are other known issues with JSON::XS not working nicely with JSON, and the recommendation is to not use it at all. https://rt.cpan.org/Public/Bug/Display.html?id=94784 This was observed with #848041 in request-tracker4. I'm honestly not sure about the best route forward on that ticket; looking at the rdeps of libjson-xs-perl, Conflicting on it may be too invasive... Thoughts welcomed! Dominic.
