 ## Latest changes
 
+* Auto-generate a "server" in OpenAPI `servers` when there's a `root_path` instead of prefixing all the `paths`:
+    * Add a new parameter for `FastAPI` classes: `root_path_in_servers` to disable the auto-generation of `servers`.
+    * New docs about `root_path` and `servers` in [Additional Servers](https://fastapi.tiangolo.com/advanced/behind-a-proxy/#additional-servers).
+    * Update OAuth2 examples to use a relative URL for `tokenUrl="token"` to make sure those examples keep working as-is even when behind a reverse proxy.
+    * Original PR [#1596](https://github.com/tiangolo/fastapi/pull/1596) by [@rkbeatss](https://github.com/rkbeatss).
 * Fix typo/link in External Links. PR [#1702](https://github.com/tiangolo/fastapi/pull/1702).
 * Update handling of [External Links](https://fastapi.tiangolo.com/external-links/) to use a data file and allow translating the headers without becoming obsolete quickly when new links are added. PR [#https://github.com/tiangolo/fastapi/pull/1701](https://github.com/tiangolo/fastapi/pull/1701).
 * Add external link [Machine learning model serving in Python using FastAPI and Streamlit](https://davidefiocco.github.io/2020/06/27/streamlit-fastapi-ml-serving.html) to docs. PR [#1669](https://github.com/tiangolo/fastapi/pull/1669) by [@davidefiocco](https://github.com/davidefiocco).
