Just for the record, they do use soname versioning,
libjson.so.0.1.0
libjson-c.so.2.0.1
but it may have been an accident to not bump it this time. The first thing
to do would be to contact them (two tickets have been opened already) and
talk about it.
Simply bumping the soname version at Fedora can easily lead to trouble,
e.g. if the next upstream release dropped more symbols together with
bumping the soname, Fedora would be out-of-sync again and would need to
stay incompatible with even another soname bump. That's not good and
inconvenient, too.
$ rpmsodiff json-c-0.11-6.fc20.x86_64.rpm json-c-0.12-1.fc20.x86_64.rpm
sonames only in json-c-0.11-6.fc20 [1]:
libjson.so.0 /usr/lib64/libjson.so.0.1.0
common sonames:
libjson-c.so.2 /usr/lib64/libjson-c.so.2.0.1 /usr/lib64/libjson-c.so.2.0.1
