-# Topology Maps
-
-NetBox can generate simple topology maps from the physical network connections recorded in its database. First, you'll need to create a topology map definition under the admin UI at Extras > Topology Maps.
-
-Each topology map is associated with a site. A site can have multiple topology maps, which might each illustrate a different aspect of its infrastructure (for example, production versus backend infrastructure).
-
-To define the scope of a topology map, decide which devices you want to include. The map will only include interface connections with both points terminated on an included device. Specify the devices to include in the **device patterns** field by entering a list of [regular expressions](https://en.wikipedia.org/wiki/Regular_expression) matching device names. For example, if you wanted to include "mgmt-switch1" through "mgmt-switch99", you might use the regex `mgmt-switch\d+`.
-
-Each line of the **device patterns** field represents a hierarchical layer within the topology map. For example, you might map a traditional network with core, distribution, and access tiers like this:
-
-```
-core-switch-[abcd]
-dist-switch\d
-access-switch\d+;oob-switch\d+
-```
-
-Note that you can combine multiple regexes onto one line using semicolons. The order in which regexes are listed on a line is significant: devices matching the first regex will be rendered first, and subsequent groups will be rendered to the right of those.

+# v2.7.0 (FUTURE)
+
+**Note:** NetBox v2.7 is the last major release that will support Python 3.5. Beginning with NetBox v2.8, Python 3.6 or
+higher will be required.
+
+## 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 definition written in YAML or
+JSON. 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.
+
+### Bulk Import of Device Components ([#822](https://github.com/netbox-community/netbox/issues/822))
+
+NetBox now supports the bulk import of device components such as console ports, power ports, and interfaces across
+multiple devices. Device components can be imported in CSV-format.
+
+Here's an example bulk import of interfaces to several devices:
+
+```
+device,name,type
+Switch1,Vlan100,Virtual
+Switch1,Vlan200,Virtual
+Switch2,Vlan100,Virtual
+Switch2,Vlan200,Virtual
+```
+
+### External File Storage ([#1814](https://github.com/netbox-community/netbox/issues/1814))
+
+In prior releases, the only option for storing uploaded files (e.g. image attachments) was to save them to the local
+filesystem on the NetBox server. This release introduces support for several remote storage backends provided by the
+[`django-storages`](https://django-storages.readthedocs.io/en/stable/) library. These include:
+
+* Amazon S3
+* ApacheLibcloud
+* Azure Storage
+* netbox-community Spaces
+* Dropbox
+* FTP
+* Google Cloud Storage
+* SFTP
+
+To enable remote file storage, first install `django-storages`:
+
+```
+pip install django-storages
+```
+
+Then, set the appropriate storage backend and its configuration in `configuration.py`. Here's an example using Amazon
+S3:
+
+```python
+STORAGE_BACKEND = 'storages.backends.s3boto3.S3Boto3Storage'
+STORAGE_CONFIG = {
+    'AWS_ACCESS_KEY_ID': '<Key>',
+    'AWS_SECRET_ACCESS_KEY': '<Secret>',
+    'AWS_STORAGE_BUCKET_NAME': 'netbox',
+    'AWS_S3_REGION_NAME': 'eu-west-1',
+}
+```

+
+## Changes
+
+### Rack Elevations Rendered via SVG ([#2248](https://github.com/netbox-community/netbox/issues/2248))
+
+NetBox v2.7 introduces a new method of rendering rack elevations as an
+[SVG](https://en.wikipedia.org/wiki/Scalable_Vector_Graphics) via a REST API endpoint. This replaces the prior method of
+rendering elevations using pure HTML which was cumbersome and had several shortcomings. Allowing elevations to be
+rendered as an SVG image in the API allows users to retrieve and make use of the drawings in their own tooling. This
+also opens the door to other feature requests related to rack elevations in the NetBox backlog.
+
+This feature implements a new REST API endpoint:
+
+```
+/api/dcim/racks/<id>/elevation/
+```
+
+By default, this endpoint returns a paginated JSON response representing each rack unit in the given elevation. This is
+the same response returned by the rack units detail endpoint and for this reason the rack units endpoint has been
+deprecated and will be removed in v2.8 (see [#3753](https://github.com/netbox-community/netbox/issues/3753)):
+
+```
+/api/dcim/racks/<id>/units/
+```
+
+In order to render the elevation as an SVG, include the `render=svg` query parameter in the request. You may also
+control the width of the elevation drawing in pixels with `unit_width=<width in pixels>` and the height of each rack
+unit with `unit_height=<height in pixels>`. The `unit_width` defaults to `230` and the `unit_height` default to `20`
+which produces elevations the same size as those that appear in the NetBox Web UI. The query parameter `face` is used to
+request either the `front` or `rear` of the elevation and defaults to `front`.
+
+Here is an example of the request url for an SVG rendering using the default parameters to render the front of the
+elevation:
+
+```
+/api/dcim/racks/<id>/elevation/?render=svg
+```
+
+Here is an example of the request url for an SVG rendering of the rear of the elevation having a width of 300 pixels and
+per unit height of 35 pixels:
+
+```
+/api/dcim/racks/<id>/elevation/?render=svg&face=rear&unit_width=300&unit_height=35
+```
+
+Thanks to [@hellerve](https://github.com/hellerve) for doing the heavy lifting on this!
+
+### Topology Maps Removed ([#2745](https://github.com/netbox-community/netbox/issues/2745))
+
+The topology maps feature has been removed to help focus NetBox development efforts.
+
+### Redis Configuration ([#3282](https://github.com/netbox-community/netbox/issues/3282))
+
+v2.6.0 introduced caching and added the `CACHE_DATABASE` option to the existing `REDIS` database configuration section.
+This did not however, allow for using two different Redis connections for the seperate caching and webhooks features.
+This change separates the Redis connection configurations in the `REDIS` section into distinct `webhooks` and `caching`
+subsections. This requires modification of the `REDIS` section of the `configuration.py` file as follows:
+
+Old Redis configuration:
+```python
+REDIS = {
+    'HOST': 'localhost',
+    'PORT': 6379,
+    'PASSWORD': '',
+    'DATABASE': 0,
+    'CACHE_DATABASE': 1,
+    'DEFAULT_TIMEOUT': 300,
+    'SSL': False,
+}
+```
+
+New Redis configuration:
+```python
+REDIS = {
+    'webhooks': {
+        'HOST': 'redis.example.com',
+        'PORT': 1234,
+        'PASSWORD': 'foobar',
+        'DATABASE': 0,
+        'DEFAULT_TIMEOUT': 300,
+        'SSL': False,
+    },
+    'caching': {
+        'HOST': 'localhost',
+        'PORT': 6379,
+        'PASSWORD': '',
+        'DATABASE': 1,
+        'DEFAULT_TIMEOUT': 300,
+        'SSL': False,
+    }
+}
+```
+
+Note that `CACHE_DATABASE` has been removed and the connection settings have been duplicated for both `webhooks` and
+`caching`. This allows the user to make use of separate Redis instances and/or databases if desired. Full connection
+details are required in both sections, even if they are the same.
+
+### WEBHOOKS_ENABLED Configuration Setting Removed ([#3408](https://github.com/netbox-community/netbox/issues/3408))
+
+As `django-rq` is now a required library, NetBox assumes that the RQ worker process is running. The installation and
+upgrade documentation has been updated to reflect this, and the `WEBHOOKS_ENABLED` configuration parameter is no longer
+used. Please ensure that both the NetBox WSGI service and the RQ worker process are running on all production
+installations.
+
+### API Choice Fields Now Use String Values ([#3569](https://github.com/netbox-community/netbox/issues/3569))
+
+NetBox's REST API presents fields which reference a particular choice as a dictionary with two keys: `value` and
+`label`. In previous versions, `value` was an integer which represented the particular choice in the database. This has
+been changed to a more human-friendly "slug" string, which is essentially a simplified version of the choice's `label`.
+
+For example, The site status field was previously represented as:
+
+```json
+"status": {
+    "value": 1,
+    "label": "Active"
+},
+```
+
+Beginning with v2.7.0, it now looks like this:
+
+```json
+"status": {
+    "value": "active",
+    "label": "Active"
+},
+```
+
+This change allows for much more intuitive representation of values, and obviates the need for API consumers to maintain
+a mapping of static integer values.
+
+Note that that all v2.7 releases will continue to accept the legacy integer values in write requests (POST, PUT, and
+PATCH) to maintain backward compatibility. This behavior will be discontinued beginning in v2.8.0.
