**Added:**
* New ``xonsh-cat`` command line utility, which is a xonsh replacement
for the standard UNIX ``cat`` command.
* The new ``xonsh.xoreutils.cat.cat_main()`` enables the ``xonsh.xoreutils.cat``
module to be run as a command line utility.
* New ``CommandsCache.is_only_functional_alias()`` and
``CommandsCache.lazy_is_only_functional_alias()`` methods for determining if
if a command name is only implemented as a function, and thus has no
underlying binary command to execute.
* ``xonsh.xontribs.xontribs_load()`` is a new first-class API for loading
xontribs via a Python function.
**Changed:**
* The xonsh Jupyter kernel now will properly redirect the output of commands
such as ``git log``, ``man``, ``less`` and other paged commands to the client.
This is done by setting ``$PAGER = 'cat'``. If ``cat`` is not available
on the system, ``xonsh-cat`` is used instead.
* The ``setup()`` function for starting up a working xonsh has ``aliases``,
``xontribs``, and ``threadable_predictors`` as new additional keyword
arguments for customizing the loading of xonsh.
**Deprecated:** None
**Removed:** None
**Fixed:**
* ``CommandsCache.locate_binary()`` will now properly return None when
``ignore_alias=False`` and the command is only a functional alias,
such as with ``cd``. Previously, it would return the name of the
command.
**Security:** None
