+## Changes
+
+### 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.
