v2.6.0 (FUTURE)

## Changes

### API Device/VM Config Context Included by Default ([#2350](https://github.com/digitalocean/netbox/issues/2350))

The rendered Config Context for Devices and VMs is now included by default in all API results (list and detail views).
Previously the rendered Config Context was only available in the detail view for objects. Users with large amounts of
context data may observe a performance drop when returning multiple objects. To combat this, in cases where the rendered
Config Context is not needed, the query parameter `?exclude=config_context` may be added to the request as to remove
the Config Context from being included in any results.

### Tag Permissions Changed

NetBox now makes use of its own `Tag` model instead of the vanilla model which ships with django-taggit. This new model
lives in the `extras` app and thus any permissions that you may have configured using "Taggit | Tag" should be changed
to now use "Extras | Tag."

v2.5.0 (2018-12-10)

## Notes

### Python 3 Required

As promised, Python 2 support has been completed removed. Python 3.5 or higher is now required to run NetBox. Please see [our Python 3 migration guide](https://netbox.readthedocs.io/en/stable/installation/migrating-to-python3/) for assistance with upgrading.

### Removed Deprecated User Activity Log

The UserAction model, which was deprecated by the new change logging feature in NetBox v2.4, has been removed. If you need to archive legacy user activity, do so prior to upgrading to NetBox v2.5, as the database migration will remove all data associated with this model.

### View Permissions in Django 2.1

Django 2.1 introduces view permissions for object types (not to be confused with object-level permissions). Implementation of [#323](https://github.com/digitalocean/netbox/issues/323) is planned for NetBox v2.6. Users are encourage to begin assigning view permissions as desired in preparation for their eventual enforcement.

### upgrade.sh No Longer Invokes sudo

The `upgrade.sh` script has been tweaked so that it no longer invokes `sudo` internally. This was done to ensure compatibility when running NetBox inside a Python virtual environment. If you need elevated permissions when upgrading NetBox, call the upgrade script with `sudo upgrade.sh`.

## New Features

### Patch Panels and Cables ([#20](https://github.com/digitalocean/netbox/issues/20))

NetBox now supports modeling physical cables for console, power, and interface connections. The new pass-through port component type has also been introduced to model patch panels and similar devices.

---

v2.4.0 (2018-08-06)

## New Features

### Webhooks ([#81](https://github.com/digitalocean/netbox/issues/81))

Webhooks enable NetBox to send a representation of an object every time one is created, updated, or deleted. Webhooks are sent from NetBox to external services via HTTP, and can be limited by object type. Services which receive a webhook can act on the data provided by NetBox to automate other tasks.

Special thanks to [John Anderson](https://github.com/lampwins) for doing the heavy lifting for this feature!

### Tagging ([#132](https://github.com/digitalocean/netbox/issues/132))

Tags are free-form labels which can be assigned to a variety of objects in NetBox. Tags can be used to categorize and filter objects in addition to built-in and custom fields. Objects to which tags apply now include a `tags` field in the API.

### Contextual Configuration Data ([#1349](https://github.com/digitalocean/netbox/issues/1349))

Sometimes it is desirable to associate arbitrary data with a group of devices to aid in their configuration. (For example, you might want to associate a set of syslog servers for all devices at a particular site.) Context data enables the association of arbitrary data (expressed in JSON format) to devices and virtual machines grouped by region, site, role, platform, and/or tenancy. Context data is arranged hierarchically, so that data with a higher weight can be entered to override more general lower-weight data. Multiple instances of data are automatically merged by NetBox to present a single dictionary for each object.

### Change Logging ([#1898](https://github.com/digitalocean/netbox/issues/1898))

When an object is created, updated, or deleted, NetBox now automatically records a serialized representation of that object (similar to how it appears in the REST API) as well the event time and user account associated with the change.

---

v2.3.0 (2018-02-26)

## New Features

### Virtual Chassis ([#99](https://github.com/digitalocean/netbox/issues/99))

A virtual chassis represents a set of physical devices with a shared control plane; for example, a stack of switches managed as a single device. Viewing the master device of a virtual chassis will show all member interfaces and IP addresses.

### Interface VLAN Assignments ([#150](https://github.com/digitalocean/netbox/issues/150))

Interfaces can now be assigned an 802.1Q mode (access or trunked) and associated with particular VLANs. Thanks to [John Anderson](https://github.com/lampwins) for his work on this!

### Bulk Object Creation via the API ([#1553](https://github.com/digitalocean/netbox/issues/1553))

The REST API now supports the creation of multiple objects of the same type using a single POST request. For example, to create multiple devices:

```
curl -X POST -H "Authorization: Token <TOKEN>" -H "Content-Type: application/json" -H "Accept: application/json; indent=4" http://localhost:8000/api/dcim/devices/ --data '[
{"name": "device1", "device_type": 24, "device_role": 17, "site": 6},
{"name": "device2", "device_type": 24, "device_role": 17, "site": 6},
{"name": "device3", "device_type": 24, "device_role": 17, "site": 6},
]'
```

Bulk creation is all-or-none: If any of the creations fails, the entire operation is rolled back.

### Automatic Provisioning of Next Available Prefixes ([#1694](https://github.com/digitalocean/netbox/issues/1694))

Similar to IP addresses, NetBox now supports automated provisioning of available prefixes from within a parent prefix. For example, to retrieve the next three available /28s within a parent /24:

```
curl -X POST -H "Authorization: Token <TOKEN>" -H "Content-Type: application/json" -H "Accept: application/json; indent=4" http://localhost:8000/api/ipam/prefixes/10153/available-prefixes/ --data '[
{"prefix_length": 28},
{"prefix_length": 28},
{"prefix_length": 28}
]'
```

If the parent prefix cannot accommodate all requested prefixes, the operation is cancelled and no new prefixes are created.

### Bulk Renaming of Device/VM Components ([#1781](https://github.com/digitalocean/netbox/issues/1781))

Device components (interfaces, console ports, etc.) can now be renamed in bulk via the web interface. This was implemented primarily to support the bulk renumbering of interfaces whose parent is part of a virtual chassis.

## Enhancements

* [#1283](https://github.com/digitalocean/netbox/issues/1283) - Added a `time_zone` field to the site model
* [#1321](https://github.com/digitalocean/netbox/issues/1321) - Added `created` and `last_updated` fields for relevant models to their API serializers
* [#1553](https://github.com/digitalocean/netbox/issues/1553) - Introduced support for bulk object creation via the API
* [#1592](https://github.com/digitalocean/netbox/issues/1592) - Added tenancy assignment for rack reservations
* [#1744](https://github.com/digitalocean/netbox/issues/1744) - Allow associating a platform with a specific manufacturer
* [#1758](https://github.com/digitalocean/netbox/issues/1758) - Added a `status` field to the site model

* [#1864](https://github.com/digitalocean/netbox/issues/1864) - Added a `status` field to the circuit model

## Bug Fixes

* [#1136](https://github.com/digitalocean/netbox/issues/1136) - Enforce model validation during bulk update
* [#1645](https://github.com/digitalocean/netbox/issues/1645) - Simplified interface serialzier for IP addresses and optimized API view queryset
* [#1838](https://github.com/digitalocean/netbox/issues/1838) - Fix KeyError when attempting to create a VirtualChassis with no devices selected
* [#1847](https://github.com/digitalocean/netbox/issues/1847) - RecursionError when a virtual chasis master device has no name
* [#1848](https://github.com/digitalocean/netbox/issues/1848) - Allow null value for interface encapsulation mode
* [#1867](https://github.com/digitalocean/netbox/issues/1867) - Allow filtering on device status with multiple values
* [#1881](https://github.com/digitalocean/netbox/issues/1881)* - Fixed bulk editing of interface 802.1Q settings
* [#1884](https://github.com/digitalocean/netbox/issues/1884)* - Provide additional context to identify devices when creating/editing a virtual chassis
* [#1907](https://github.com/digitalocean/netbox/issues/1907) - Allow removing an IP as the primary for a device when editing the IP directly

\* New since v2.3-beta2

## Breaking Changes

* Constants representing device status have been renamed for clarity (for example, `STATUS_ACTIVE` is now `DEVICE_STATUS_ACTIVE`). Custom validation reports will need to be updated if they reference any of these constants.

## API Changes

* API creation calls now accept either a single JSON object or a list of JSON objects. If multiple objects are passed and one or more them fail validation, no objects will be created.
* Added `created` and `last_updated` fields for objects inheriting from CreatedUpdatedModel.

v2.2.0 (2017-10-12)

**Note:** This release requires PostgreSQL 9.4 or higher. Do not attempt to upgrade unless you are running at least PostgreSQL 9.4.

**Note:** The release replaces the deprecated pycrypto library with [pycryptodome](https://github.com/Legrandin/pycryptodome). The upgrade script has been extended to automatically uninstall the old library, but please verify your installed packages with `pip freeze | grep pycrypto` if you run into problems.

## New Features

### Virtual Machines and Clusters ([#142](https://github.com/digitalocean/netbox/issues/142))

Our second-most popular feature request has arrived! NetBox now supports the creation of virtual machines, which can be assigned virtual interfaces and IP addresses. VMs are arranged into clusters, each of which has a type and (optionally) a group.

### Custom Validation Reports ([#1511](https://github.com/digitalocean/netbox/issues/1511))

Users can now create custom reports which are run to validate data in NetBox. Reports work very similar to Python unit tests: Each report inherits from NetBox's Report class and contains one or more test method. Reports can be run and retrieved via the web UI, API, or CLI. See [the docs](http://netbox.readthedocs.io/en/stable/miscellaneous/reports/) for more info.

---

v2.1.0 (2017-07-25)

## New Features

### IP Address Roles ([#819](https://github.com/digitalocean/netbox/issues/819))

The IP address model now supports the assignment of a functional role to help identify special-purpose IPs. These include:

* Loopback
* Secondary
* Anycast
* VIP
* VRRP
* HSRP
* GLBP

### Automatic Provisioning of Next Available IP ([#1246](https://github.com/digitalocean/netbox/issues/1246))

A new API endpoint has been added at `/api/ipam/prefixes/<pk>/available-ips/`. A GET request to this endpoint will return a list of available IP addresses within the prefix (up to the pagination limit). A POST request will automatically create and return the next available IP address.

### NAPALM Integration ([#1348](https://github.com/digitalocean/netbox/issues/1348))

The [NAPALM automation](https://napalm-automation.net/) library provides an abstracted interface for pulling live data (e.g. uptime, software version, running config, LLDP neighbors, etc.) from network devices. The NetBox API has been extended to support executing read-only NAPALM methods on devices defined in NetBox. To enable this functionality, ensure that NAPALM has been installed (`pip install napalm`) and the `NETBOX_USERNAME` and `NETBOX_PASSWORD` [configuration parameters](http://netbox.readthedocs.io/en/stable/configuration/optional-settings/#netbox_username) have been set in configuration.py.

v1.9.0-r1 (2017-03-03)

## New Features

### Rack Reservations ([#36](https://github.com/digitalocean/netbox/issues/36))

Users can now reserve an arbitrary number of units within a rack, adding a comment noting their intentions. Reservations do not interfere with installed devices: It is possible to reserve a unit for future use even if it is currently occupied by a device.

### Interface Groups ([#105](https://github.com/digitalocean/netbox/issues/105))

A new Link Aggregation Group (LAG) virtual form factor has been added. Physical interfaces can be assigned to a parent LAG interface to represent a port-channel or similar logical bundling of links.

### Regions ([#164](https://github.com/digitalocean/netbox/issues/164))

A new region model has been introduced to allow for the geographic organization of sites. Regions can be nested recursively to form a hierarchy.

### Rackless Devices ([#198](https://github.com/digitalocean/netbox/issues/198))

Previous releases required each device to be assigned to a particular rack within a site. This requirement has been relaxed so that devices must only be assigned to a site, and may optionally be assigned to a rack.

### Global VLANs ([#235](https://github.com/digitalocean/netbox/issues/235))

Assignment of VLANs and VLAN groups to sites is now optional, allowing for the representation of a VLAN spanning multiple sites.

---

v1.8.0 (2017-01-03)

## New Features

### Point-to-Point Circuits ([#49](https://github.com/digitalocean/netbox/issues/49))

Until now, NetBox has supported tracking only one end of a data circuit. This is fine for Internet connections where you don't care (or know) much about the provider side of the circuit, but many users need the ability to track inter-site circuits as well. This release expands circuit modeling so that each circuit can have an A and/or Z side. Each endpoint must be terminated to a site, and may optionally be terminated to a specific device and interface within that site.

### L4 Services ([#539](https://github.com/digitalocean/netbox/issues/539))

Our first major community contribution introduces the ability to track discrete TCP and UDP services associated with a device (for example, SSH or HTTP). Each service can optionally be assigned to one or more specific IP addresses belonging to the device. Thanks to [@if-fi](https://github.com/if-fi) for the addition!
