As promised, Python 2 support has been completed removed. Python 3.5 or higher is now required to run NetBox. Please see [our Python 3 migration guide](https://docs.netbox.dev/en/stable/installation/migrating-to-python3/) for assistance with upgrading.
The UserAction model, which was deprecated by the new change logging feature in NetBox v2.4, has been removed. If you need to archive legacy user activity, do so prior to upgrading to NetBox v2.5, as the database migration will remove all data associated with this model.
Django 2.1 introduces view permissions for object types (not to be confused with object-level permissions). Implementation of [#323](https://github.com/netbox-community/netbox/issues/323) is planned for NetBox v2.6. Users are encourage to begin assigning view permissions as desired in preparation for their eventual enforcement.
The `upgrade.sh` script has been tweaked so that it no longer invokes `sudo` internally. This was done to ensure compatibility when running NetBox inside a Python virtual environment. If you need elevated permissions when upgrading NetBox, call the upgrade script with `sudo upgrade.sh`.
NetBox now supports modeling physical cables for console, power, and interface connections. The new pass-through port component type has also been introduced to model patch panels and similar devices.
