JSON Diff (mcepl/json_diff)

The `json-diff` library (maintained by mcepl) provides a command-line tool to compare two JSON files and output their structural differences. While it was ported to Python 3 in its 1.5.0 release, its development has been inactive since 2019. It aims to identify additions, deletions, and modifications between JSON structures, generating a new JSON file or console output with the result. This library is considered to be in maintenance mode due to its age and lack of recent updates.
