Certain components of NetBox (such as the display of rack elevation diagrams) rely on the use of embedded objects. Ensure that your HTTP server configuration does not override the `X-Frame-Options` response header set by NetBox.
## gunicorn Installation
## gunicorn Configuration
Check that the Python virtual environment created in [the previous step](3-netbox.md#set-up-python-environment) is still active, and install the `gunicorn` Python package. (If the virtual environment is not active, activate it with the command `source /opt/netbox/venv/bin/activate`.)

These service files assume that gunicorn is installed at `/usr/local/bin/gunicorn`. If the output of `which gunicorn` indicates a different path, you'll need to correct the `ExecStart` path in both files.
Then, start the `netbox` and `netbox-rq` services and enable them to initiate at boot time:

# Review the Release Notes
## Review the Release Notes
Prior to upgrading your NetBox instance, be sure to carefully review all [release notes](../../release-notes/) that have been published since your current version was released. Although the upgrade process typically does not involve additional work, certain releases may introduce breaking or backward-incompatible changes. These are called out in the release notes under the version in which the change went into effect.
