+## New Features
+
+### Enhanced Device Type Import ([#451](https://github.com/netbox-community/netbox/issues/451))
+
+NetBox now supports the import of device types and related component templates using a YAML- or JSON-based definition.
+For example, the following will create a new device type with four network interfaces, two power ports, and a console
+port:
+
+```yaml
+manufacturer: Acme
+model: Packet Shooter 9000
+slug: packet-shooter-9000
+u_height: 1
+interfaces:
+  - name: ge-0/0/0
+    type: 1000base-t
+  - name: ge-0/0/1
+    type: 1000base-t
+  - name: ge-0/0/2
+    type: 1000base-t
+  - name: ge-0/0/3
+    type: 1000base-t
+power-ports:
+  - name: PSU0
+  - name: PSU1
+console-ports:
+  - name: Console
+```
+
+This new functionality replaces the existing CSV-based import form, which did not allow for component template import.
