 ## Backward Incompatibilities {#sec-release-21.11-incompatibilities}
 
+- The NixOS VM test framework, `pkgs.nixosTest`/`make-test-python.nix`, now requires non-terminating commands such as `succeed("foo &")` to close stdout.
+  This can be done with a redirect such as `succeed("foo >&2 &")`. This breaking change was necessitated by a race condition causing tests to fail or hang.
+  It applies to all methods that invoke commands on the nodes, including `execute`, `succeed`, `fail`, `wait_until_succeeds`, `wait_until_fails`.
+
 - The `services.wakeonlan` option was removed, and replaced with `networking.interfaces.<name>.wakeOnLan`.
 
 - The `security.wrappers` option now requires to always specify an owner, group and whether the setuid/setgid bit should be set.
