-## Caching Configuration
-
-By default, all query operations within a plugin are cached. To change this, define a caching configuration under the PluginConfig class' `caching_config` attribute. All configuration keys will be applied within the context of the plugin; there is no need to include the plugin name. An example configuration is below:
-
-```python
-class MyPluginConfig(PluginConfig):
-    ...
-    caching_config = {
-        'foo': {
-            'ops': 'get',
-            'timeout': 60 * 15,
-        },
-        '*': {
-            'ops': 'all',
-        }
-    }
-```
-
-To disable caching for your plugin entirely, set:
-
-```python
-caching_config = {
-    '*': None
-}
-```
-
-See the [django-cacheops](https://github.com/Suor/django-cacheops) documentation for more detail on configuring caching.

 ### Breaking Changes
 
 * The default CSV export format for all objects now includes all available data. Additionally, the CSV headers now use human-friendly titles rather than the raw field names.
+* Support for queryset caching configuration (`caching_config`) has been removed from the plugins API (see [#6639](https://github.com/netbox-community/netbox/issues/6639)).
