+# VLAN Translation Policies
+
+!!! info "This feature was introduced in NetBox v4.2."
+
+VLAN translation is a feature that consists of VLAN translation policies and [VLAN translation rules](./vlantranslationrule.md). Many rules can belong to a policy, and each rule defines a mapping of a local to remote VLAN ID (VID). A policy can then be assigned to an [Interface](../dcim/interface.md) or [VMInterface](../virtualization/vminterface.md), and all VLAN translation rules associated with that policy will be visible in the interface details.
+
+There are uniqueness constraints on `(policy, local_vid)` and on `(policy, remote_vid)` in the `VLANTranslationRule` model. Thus, you cannot have multiple rules linked to the same policy that have the same local VID or the same remote VID. A set of policies and rules might look like this:
+
+Policy 1:
+- Rule: 100 -> 200
+- Rule: 101 -> 201
+
+Policy 2:
+- Rule: 100 -> 300

 # Staged Changes
 
-!!! danger "Experimental Feature"
-    This feature is still under active development and considered experimental in nature. Its use in production is strongly discouraged at this time.
+!!! danger "Deprecated Feature"
+    This feature has been deprecated in NetBox v4.2 and will be removed in a future release. Please consider using the [netbox-branching plugin](https://github.com/netboxlabs/netbox-branching), which provides much more robust functionality.
 
 NetBox provides a programmatic API to stage the creation, modification, and deletion of objects without actually committing those changes to the active database. This can be useful for performing a "dry run" of bulk operations, or preparing a set of changes for administrative approval, for example.

 Additionally, a `render()` method is available for convenience. This method accepts the name of a template to render, and any additional context data you want to pass. Its use is optional, however.
 
 To control where the custom content is injected, plugin authors can specify an iterable of models by overriding the `models` attribute on the subclass. Extensions which do not specify a set of models will be invoked on every view, where supported.

+
+## v4.2.0 (2025-01-06)
+
+### Breaking Changes
+
+* Support for the Django admin UI has been completely removed. (The Django admin UI was disabled by default in NetBox v4.0.)
+* This release drops support for PostgreSQL 12. PostgreSQL 13 or later is required to run this release.
+* NetBox has adopted collation-based natural ordering for many models. This may alter the order in which some objects are listed by default.
+* Automatic redirects from pre-v4.1 UI views for virtual disks have been removed.
+* The `site` and `provider_network` foreign key fields on `circuits.CircuitTermination` have been replaced by the `termination` generic foreign key.
+* The `site` foreign key field on `ipam.Prefix` has been replaced by the `scope` generic foreign key.
+* The `site` foreign key field on `virtualization.Cluster` has been replaced by the `scope` generic foreign key.
+* The `circuit` foreign key field on `circuits.CircuitGroupAssignment` has been replaced by the `member` generic foreign key.
+* Obsolete nested REST API serializers have been removed. These were deprecated in NetBox v4.1 under [#17143](https://github.com/netbox-community/netbox/issues/17143).
+
+### New Features
+
+#### Assign Multiple MAC Addresses per Interface ([#4867](https://github.com/netbox-community/netbox/issues/4867))
+
+MAC addresses are now managed as independent objects, rather than attributes on device and VM interfaces. NetBox now supports the assignment of multiple MAC addresses per interface, and allows a primary MAC address to be designated for each.
+
+#### Quick Add UI Widget ([#5858](https://github.com/netbox-community/netbox/issues/5858))
+
+A new UI widget has been introduced to enable conveniently creating new related objects while creating or editing an object. For instance, it is now possible to create and assign a new device role when creating or editing a device from within the device form.
+
+#### VLAN Translation ([#7336](https://github.com/netbox-community/netbox/issues/7336))
+
+User can now define policies which track the translation of VLAN IDs on IEEE 802.1Q-encapsulated interfaces. Translation policies can be reused across multiple interfaces.
+
+#### Virtual Circuits ([#13086](https://github.com/netbox-community/netbox/issues/13086))
+
+New models have been introduced to support the documentation of virtual circuits as an extension to the physical circuit modeling already supported. This enables users to accurately reflect point-to-point or multipoint virtual circuits atop infrastructure comprising physical circuits and cables.
+
+#### Q-in-Q Encapsulation ([#13428](https://github.com/netbox-community/netbox/issues/13428))
+
+NetBox now supports the designation of customer VLANs (CVLANs) and service VLANs (SVLANs) to support IEEE 802.1ad/Q-in-Q encapsulation. Each interface can now have it mode designated "Q-in-Q" and be assigned an SVLAN.
+
+### Enhancements
+
+* [#6414](https://github.com/netbox-community/netbox/issues/6414) - Prefixes can now be scoped by region, site group, site, or location
+* [#7699](https://github.com/netbox-community/netbox/issues/7699) - Virtualization clusters can now be scoped by region, site group, site, or location
+* [#9604](https://github.com/netbox-community/netbox/issues/9604) - The scope of a circuit termination now include a region, site group, site, location, or provider network
+* [#10711](https://github.com/netbox-community/netbox/issues/10711) - Wireless LANs can now be scoped by region, site group, site, or location
+* [#11279](https://github.com/netbox-community/netbox/issues/11279) - Improved the use of natural ordering for various models throughout the application
+* [#12596](https://github.com/netbox-community/netbox/issues/12596) - Extended the virtualization clusters REST API endpoint to report on allocated VM resources
+* [#16547](https://github.com/netbox-community/netbox/issues/16547) - Add a geographic distance field for circuits
+* [#16783](https://github.com/netbox-community/netbox/issues/16783) - Add an operational status field for inventory items
+* [#17195](https://github.com/netbox-community/netbox/issues/17195) - Add a color field for power outlets
+
+### Plugins
+
+* [#15093](https://github.com/netbox-community/netbox/issues/15093) - Introduced the `events_pipeline` configuration parameter, which allows plugins to hook into NetBox event processing
+* [#16546](https://github.com/netbox-community/netbox/issues/16546) - NetBoxModel now provides a default `get_absolute_url()` method
+* [#16971](https://github.com/netbox-community/netbox/issues/16971) - Plugins can now easily register system jobs to perform background tasks
+* [#17029](https://github.com/netbox-community/netbox/issues/17029) - Registering a `PluginTemplateExtension` subclass for a single model has been deprecated (replace `model` with `models`)
+* [#18023](https://github.com/netbox-community/netbox/issues/18023) - Extend `register_model_view()` to handle list views
+
+### Other Changes
+
+* [#16136](https://github.com/netbox-community/netbox/issues/16136) - Removed support for the Django admin UI
+* [#17165](https://github.com/netbox-community/netbox/issues/17165) - All obsolete nested REST API serializers have been removed
+* [#17472](https://github.com/netbox-community/netbox/issues/17472) - The legacy staged changes API has been deprecated, and will be removed in Netbox v4.3
