# NetBox v3.3

## v3.3.0 (FUTURE)

### Breaking Changes

* The `nat_outside` relation on the IP address model now returns a list of zero or more related IP addresses, rather than a single instance (or None).

### Enhancements

* [#1202](https://github.com/netbox-community/netbox/issues/1202) - Support overlapping assignment of NAT IP addresses
* [#8495](https://github.com/netbox-community/netbox/issues/8495) - Enable custom field grouping
* [#8995](https://github.com/netbox-community/netbox/issues/8995) - Enable arbitrary ordering of REST API results

### Other Changes

* [#9261](https://github.com/netbox-community/netbox/issues/9261) - `NetBoxTable` no longer automatically clears pre-existing calls to `prefetch_related()` on its queryset

### REST API Changes

* extras.CustomField
    * Added `group_name` field
* ipam.IPAddress
    * The `nat_inside` field no longer requires a unique value
    * The `nat_outside` field has changed from a single IP address instance to a list of multiple IP addresses
