+
+## Virtual Machine Types
+
+A virtual machine type provides reusable classification for virtual machines and can define create-time defaults for platform, vCPUs, and memory. This is useful when multiple virtual machines share a common sizing or profile while still allowing per-instance overrides after creation.
 
 ## Virtual Machines
 
-A virtual machine is a virtualized compute instance. These behave in NetBox very similarly to device objects, but without any physical attributes. For example, a VM may have interfaces assigned to it with IP addresses and VLANs, however its interfaces cannot be connected via cables (because they are virtual). Each VM may also define its compute, memory, and storage resources as well.

 !!! warning
     Disabling the page size limit introduces a potential for very resource-intensive requests, since one API request can effectively retrieve an entire table from the database.
 
+### Cursor-Based Pagination
+
+For large datasets, offset-based pagination can become inefficient because the database must scan all rows up to the offset. As an alternative, cursor-based pagination uses the `start` query parameter to filter results by primary key (PK), enabling efficient keyset pagination.
+
+To use cursor-based pagination, pass `start` (the minimum PK value) and `limit` (the page size):
+
+```
+http://netbox/api/dcim/devices/?start=0&limit=100
+```
+
+This returns objects with an `id` greater than or equal to zero, ordered by PK, limited to 100 results. Below is an example showing an arbitrary `start` value.
+
+```json
+{
+    "count": null,
+    "next": "http://netbox/api/dcim/devices/?start=356&limit=100",
+    "previous": null,

+            ...
+        }
+    ]
+}
+```
+
+To iterate through all results, use the `id` of the last object in each response plus one as the `start` value for the next request. Continue until `next` is null.
+
+!!! info
+    Some important differences from offset-based pagination:
+
+    * `start` and `offset` are **mutually exclusive**; specifying both will result in a 400 error.
+    * Results are always ordered by primary key when using `start`. This is required to ensure deterministic behavior.
+    * `count` is always `null` in cursor mode, as counting all matching rows would partially negate its performance benefit.
+    * `previous` is always `null`: cursor-based pagination supports only forward navigation.

+
+For example, an interface template named `Gi{vc_position}/{module}/0` installed on a Virtual Chassis
+member with position `2` and module bay position `3` will be rendered as `Gi2/3/0`.
+
+If the device is not a member of a Virtual Chassis, `{vc_position}` defaults to `0`. A custom
+fallback value can be specified using the syntax `{vc_position:X}`, where `X` is the desired default.
+For example, `{vc_position:1}` will render as `1` when no Virtual Chassis position is set.
+
 Automatic renaming is supported for all modular component types (those listed above).
 
+### Position Inheritance for Nested Modules
+
+When using nested module bays (modules installed inside other modules), the `{module}` placeholder
+can also be used in the **position** field of module bay templates to inherit the parent bay's
+position. This allows a single module type to produce correctly named components at any nesting
+depth, with a user-controlled separator.
+
+For example, a line card module type might define sub-bay positions as `{module}/1`, `{module}/2`,
+etc. When the line card is installed in a device bay with position `3`, these sub-bay positions
+resolve to `3/1`, `3/2`, etc. An SFP module type with interface template `SFP {module}` installed
+in sub-bay `3/2` then produces interface `SFP 3/2`.
+
+The separator between levels is defined by the user in the position field template itself. Using
+`{module}-1` produces positions like `3-1`, while `{module}.1` produces `3.1`. This provides
+full flexibility without requiring a global separator configuration.
+
+!!! note
+    If the position field does not contain `{module}`, no inheritance occurs and behavior is
+    unchanged from previous versions.

+# Custom Model Actions
+
+Plugins can register custom permission actions for their models. These actions appear as checkboxes in the ObjectPermission form, making it easy for administrators to grant or restrict access to plugin-specific functionality without manually entering action names.
+
+For example, a plugin might define a "sync" action for a model that syncs data from an external source, or a "bypass" action that allows users to bypass certain restrictions.
+
+## Registering Model Actions
+
+The preferred way to register custom actions is via Django's `Meta.permissions` on the model class. NetBox will automatically register these as model actions when the app is loaded:
+
+```python
+from netbox.models import NetBoxModel
+
+class MyModel(NetBoxModel):
+    # ...
+
+    class Meta:
+        permissions = [
+            ('sync', 'Synchronize data from external source'),
+            ('export', 'Export data to external system'),
+        ]
+```
+
+Once registered, these actions appear as checkboxes in a flat list when creating or editing an ObjectPermission.

+# NetBox v4.6
+
+## v4.6.0-beta2 (2026-04-28)
+
+### New Features
+
+#### Virtual Machine Types ([#5795](https://github.com/netbox-community/netbox/issues/5795))
+
+A new VirtualMachineType model has been introduced to enable categorization of virtual machines by instance type, analogous to how DeviceType categorizes physical hardware. VM types can be defined once and reused across many virtual machines.
+
+#### Cable Bundles ([#20151](https://github.com/netbox-community/netbox/issues/20151))
+
+A new CableBundle model allows individual cables to be grouped together to represent physical cable runs that are managed as a unit; e.g. a bundle of 48 CAT6 cables between two patch panels. (Please note that this feature is _not_ suitable for modeling individual fiber strands within a single cable.)
+
+#### Rack Groups ([#20961](https://github.com/netbox-community/netbox/issues/20961))
+
+A flat RackGroup model has been reintroduced to provide a lightweight secondary axis of rack organization (e.g. by row or aisle) that is independent of the location hierarchy. Racks carry an optional foreign key to a RackGroup, and RackGroup can also serve as a scope for VLANGroup assignments.
+
+#### ETag Support for REST API ([#21356](https://github.com/netbox-community/netbox/issues/21356))
+
+The REST API now returns an `ETag` header on responses for individual objects, derived from the object's last-updated timestamp. Clients can supply an `If-Match` header on PUT/PATCH requests to guard against conflicting concurrent updates; if the object has been modified since the ETag was issued, the server returns a 412 (Precondition Failed) response.
+
+#### Cursor-based Pagination for REST API ([#21363](https://github.com/netbox-community/netbox/issues/21363))
+
+A new `start` query parameter has been introduced as an efficient alternative to the existing `offset` parameter for paginating large result sets. Rather than scanning the table up to a relative offset, the `start` parameter filters for objects with a primary key equal to or greater than the given value, enabling constant-time pagination regardless of result set size.
+
