**Removed:**

* xontrib ``prompt_ret_code`` is now removed.
  Now the default prompt already shows the last-return-code when the previous command fails.
  Please use the new prompt fields ``last_return_code``, ``last_return_code_if_nonzero`` from
  the `PR <https://github.com/xonsh/xonsh/pull/4798>`_
