Does replacing a key decrements the reference count ?

[Sunslash]

Hello, I am currently writing an application using jansson, and I would like to avoid any memory issues.

Let's say I have added a key to a json object json_object_set_new(my_json, "key", my_value);

And then later decide to replace the value json_object_set(my_json, "key", my_new_value);

What happens to the old json object ? Is it decremented and destroyed ? Or should I manage this myself ?

Yep, it will be decremented and destroyed. Stacktrace:
