The modules ``pexpect.screen`` and ``pexpect.ANSI`` have been deprecated in
Pexpect version 4. They were separate from the main use cases for Pexpect, and
there are better maintained Python terminal emulator packages, such as
`pyte <https://pypi.python.org/pypi/pyte>`__.
These modules are still present for now, but we don't advise using them in new
code.

* It is now possible to call :meth:`~.wait` multiple times, or after a process
is already determined to be terminated without raising an exception
(:ghpull:`211`).
* Deprecated ``pexpect.screen`` and ``pexpect.ANSI``. Please use other packages
such as `pyte <https://pypi.python.org/pypi/pyte>`__ to emulate a terminal.
* Removed the independent top-level modules (``pxssh fdpexpect FSM screen ANSI``)
which were installed alongside Pexpect. These were moved into the Pexpect
package in 3.0, but the old names were left as aliases.
