Discussion: Benefits and Drawbacks

The current variable names version and full_version can be ambiguous, as it’s not immediately clear whether they refer to the API version, the NetBox application version, or something else.

This change renames them to:

• api_version → clearly indicates the version of the NetBox API being used.
• netbox_version → explicitly refers to the full NetBox application version.

Benefits:

• Improves code clarity and readability.
• Reduces potential confusion when working with both API and application versions.
• Aligns terminology with NetBox documentation and common conventions.
