 ### Viewing Objects
 
-Object-based permissions work by filtering the database query generated by a user's request to restrict the set of objects returned. When a request is received, NetBox first determines whether the user is authenticated and has been granted to perform the requested action. For example, if the requested URL is `/dcim/devices/`, NetBox will check for the `dcim.view_device` permission. If the user has not been assigned this permission (either directly or via a group assignment), NetBox will return a 403 (forbidden) HTTP response.

+## Compatibility Matrix
+
+Consider adding a file named `COMPATIBILITY.md` to your plugin project root (alongside `pyproject.toml`). This file should contain a table listing the minimum and maximum supported versions of NetBox (`min_version` and `max_version`) for each release. This serves as a handy reference for users who are upgrading from a previous version of your plugin. An example is shown below:
+
+```markdown title="COMPATIBILITY.md"
+# Compatibility Matrix
+
+| Release | Minimum NetBox Version | Maximum NetBox Version |
+|---------|------------------------|------------------------|
+| 0.2.0   | 4.4.0                  | 4.5.x                  |

+```
+
 ## Create a Virtual Environment
 
 It is strongly recommended to create a Python [virtual environment](https://docs.python.org/3/tutorial/venv.html) for the development of your plugin, as opposed to using system-wide packages. This will afford you complete control over the installed versions of all dependencies and avoid conflict with system packages. This environment can live wherever you'd like;however, it should be excluded from revision control. (A popular convention is to keep all virtual environments in the user's home directory, e.g. `~/.virtualenvs/`.)

 #### Lookup Modifiers in Filter Forms ([#7604](https://github.com/netbox-community/netbox/issues/7604))
 
-Most object list filters within the UI have been extended to include optional lookup modifiers to support more complex queries. For instance, filters for numeric values now include a dropdown where a user can select "less than," "greater than," or "not" in addition to the default equivalency match. The specific modifiers available depend on the type of each filter.

The specific modifiers available depend on the type of each filter. Plugins can register their own filtersets using the `register_filterset()` decorator to enable this new functionality.
 
 (Note that this feature does not introduce any new filters. Rather, it makes available in the UI filters which already exist.)
