+- Observed addresses (aka. external address candidates) of the local node, reported by a remote node via `libp2p-identify`, are no longer automatically considered confirmed external addresses, in other words they are no longer trusted by default.
+  Instead users need to confirm the reported observed address either manually, or by using `libp2p-autonat`.
+  In trusted environments users can simply extract observed addresses from a `libp2p-identify::Event::Received { info: libp2p_identify::Info { observed_addr }}` and confirm them via `Swarm::add_external_address`.
+  See [PR 3954] and [PR 4052].

 - Automatically configure client/server mode based on external addresses.
-  If we have or learn about an external address of our node, we operate in server-mode and thus allow inbound requests.
+  If we have or learn about an external address of our node, e.g. through `Swarm::add_external_address` or automated through `libp2p-autonat`, we operate in server-mode and thus allow inbound requests.
   By default, a node is in client-mode and only allows outbound requests.
+  If you want to maintain the status quo, i.e. always operate in server mode, make sure to add at least one external address through `Swarm::add_external_address`.
+  See also [Kademlia specification](https://github.com/libp2p/specs/tree/master/kad-dht#client-and-server-mode) for an introduction to Kademlia client/server mode.

+# Run tests
+
+First you need to build and start the echo-server:
+
+```
+docker build -t echo-server echo-server
+docker run -it --rm --network=host echo-server
+```
+
+On another terminal run:
+
+```
+wasm-pack test --chrome
+```
+
+Navigate with your browser at http://127.0.0.1:8000.
+
+You can also run the tests on a headless browser:
+
+```
+wasm-pack test --chrome --headless
+```
+
+> **Note:** For headless tests your Chrome browser needs to be compatible
+> with chromedriver (i.e. they must have the same major version).
+>
+> You may need to define the path of chromedriver with `--chromedriver=/path/to/chromedriver`.
