+* `#334 <https://github.com/dw/mitogen/issues/334>`_: the SSH method
+   tilde-expands private key paths using Ansible's logic. Previously Mitogen
+   passed the path unmodified to SSH, which would expand it using
+   :func:`os.getpwent`.
+
+   This differs from :func:`os.path.expanduser`, which prefers the ``HOME``
+   environment variable if it is set, causing behaviour to diverge when Ansible
+   was invoked using sudo without appropriate flags to cause the ``HOME``
+   environment variable to be reset to match the target account.
