+# Updates to Python (or to OpenBSD)
+Whenever [Python](https://python.org) is updated (which often happens when [OpenBSD](https://openbsd.org) is updated) the [virtual Python environment](https://docs.python.org/3/library/venv.html) does not automatically reflect these changes. Updating the [virtual Python environment](https://docs.python.org/3/library/venv.html) essentially means creating a new one.
+
+Note: This also updates Radicale to the newest version.
+
+1. Stop the Radicale service:\
+`# rcctl stop radicale3`
+2. [Optional] Make a backup of the existing [virtual Python environment](https://docs.python.org/3/library/venv.html), e.g. by renaming it:\
+`# mv /usr/local/lib/radicale /usr/local/lib/radicale-backup`
+3. Recreate the [virtual Python environment](https://docs.python.org/3/library/venv.html) as described [above](#installing-radicale):
+   - Create a [virtual Python environment](https://docs.python.org/3/library/venv.html) to avoid mixing [pkg_add(1)](https://man.openbsd.org/pkg_add) and [pip](https://pypi.org/project/pip/) managed code:\
+`# python3 -m venv /usr/local/lib/radicale`
+   - [Optional] Update [pip](https://pypi.org/project/pip/) in the [virtual Python environment](https://docs.python.org/3/library/venv.html) to silence warnings when using [pip](https://pypi.org/project/pip/):\
+`# /usr/local/lib/radicale/bin/pip install --upgrade pip`
+   - Install Radicale into the [virtual Python environment](https://docs.python.org/3/library/venv.html):\
+`# /usr/local/lib/radicale/bin/pip install radicale`
+4. Make any required changes to the configuration if the new version of Radicale requires any changes.
+5. Start the Radicale service:\
+`# rcctl start radicale3`
+6. [Optional] Remove the backup created in step 2 when everything is working as expected.
