 Inventory items represent hardware components installed within a device, such as a power supply or CPU or line card. Inventory items are distinct from other device components in that they cannot be templatized on a device type, and cannot be connected by cables. They are intended to be used primarily for inventory purposes.
 
-Each inventory item can be assigned a manufacturer, part ID, serial number, and asset tag (all optional). A boolean toggle is also provided to indicate whether each item was entered manually or discovered automatically (by some process outside of NetBox).
+Each inventory item can be assigned a functional role, manufacturer, part ID, serial number, and asset tag (all optional). A boolean toggle is also provided to indicate whether each item was entered manually or discovered automatically (by some process outside of NetBox).
 
 Inventory items are hierarchical in nature, such that any individual item may be designated as the parent for other items. For example, an inventory item might be created to represent a line card which houses several SFP optics, each of which exists as a child item within the device.

+# Inventory Item Roles
+
+Inventory items can be organized by functional roles, which are fully customizable by the user. For example, you might create roles for power supplies, fans, interface optics, etc.

 A new REST API endpoint has been added at `/api/ipam/vlan-groups/<pk>/available-vlans/`. A GET request to this endpoint will return a list of available VLANs within the group. A POST request can be made to this endpoint specifying the name(s) of one or more VLANs to create within the group, and their VLAN IDs will be assigned automatically.
 
+#### Inventory Item Roles ([#3087](https://github.com/netbox-community/netbox/issues/3087))
+
+A new model has been introduced to represent function roles for inventory items, similar to device roles. The assignment of roles to inventory items is optional.

 #### Modules & Module Types ([#7844](https://github.com/netbox-community/netbox/issues/7844))
 
 Several new models have been added to support field-replaceable device modules, such as those within a chassis-based switch or router. Similar to devices, each module is instantiated from a user-defined module type, and can have components associated with it. These components become available to the parent device once the module has been installed within a module bay. This makes it very convenient to replicate the addition and deletion of device components as modules are installed and removed.
