- update to version 0.8.8
 - Added:
  - ``vox new`` has an added ``-p --interpreter`` flag for choosing the python interpreter to use for virtualenv creation
  - The default Python intrepreter vox uses to create virtual environments can be set using the ``$VOX_DEFAULT_INTERPRETER`` environment variable.
 - Changed:
  - ``lib.ChainDB`` now resolves results to the type of the inputs if possible
- update to version 0.8.7
 - Added:
  - New xonsh syntax ``pf`` strings -- combining path strings with f-strings.
    Usage:
    .. code-block:: bash
         gil@bad_cat ~ $ repos = 'github.com'
         gil@bad_cat ~ $ pf"~/{repos}"
         PosixPath('/home/gil/github.com')
         gil@bad_cat ~ $ pf"{$HOME}"
         PosixPath('/home/gil')
         gil@bad_cat ~ $ pf"/home/${'US' + 'ER'}"
         PosixPath('/home/gil')
 - Fixed:
  - Set ``ls`` to ``predict_true`` in ``default_threadable_predictors``.  This prevents ``ls`` on OSX
    from being flagged on OSX as unthreadable (incorrectly) because it relies on ``ncurses``.
- update to version 0.8.6
 - Added:
  - Doco about how to update xonsh and how to set and unset environment variables
 - Fixed:
  - Updated behavior of the ``cat`` coreutils function so that it properly
    handles as vareity of cases such as:
      * Exits after concatenating normal files which have a finite size
      * Continues to run for special files which do not have a size,
        such as ``/dev/random``
      * Is interruptable in all cases with Crtl-C.
  - Callable aliases were not properly raising a ``CalledProcessError`` when they
    returned a non-zero exist status when ``$RAISE_SUBPROC_ERROR = True``. This has
    been fixed.
  - Fixed interpretation of color names with PTK2 and Pygments 2.3.1.
- update to version 0.8.5
 - Added:
  - Add alias to `base16 shell <https://github.com/chriskempson/base16-shell>`_
  - Installation / Usage
      1. To install use pip
      .. code-block:: bash
          python3 -m pip install xontrib-base16-shell
      2. Add on ``~/.xonshrc``
      .. code:: python
          :number-lines:
          $BASE16_SHELL = $HOME + "/.config/base16-shell/"
          xontrib load base16_shell
      3. See image

  - New ``DumbShell`` class that kicks in whenever ``$TERM == "dumb"``.
    This usually happens in emacs. Currently, this class inherits from
    the ``ReadlineShell`` but adds some light customization to make
    sure that xonsh looks good in the resultant terminal emulator.
  - Aliases from foreign shells (e.g. Bash) that are more than single expressions,
    or contain sub-shell executions, are now evaluated and run in the foreign shell.
    Previously, xonsh would attempt to translate the alias from sh-lang into
    xonsh. These restrictions have been removed.  For example, the following now
    works:
    .. code-block:: sh
        $ source-bash 'alias eee="echo aaa \$(echo b)"'
        $ eee
        aaa b
  - New ``ForeignShellBaseAlias``, ``ForeignShellFunctionAlias``, and
    ``ForeignShellExecAlias`` classes have been added which manage foreign shell
    alias execution.
 - Changed:
  - String aliases will now first be checked to see if they contain sub-expressions
    that require evaluations, such as ``@(expr)``, ``$[cmd]``, etc. If they do,
    then an ``ExecAlias`` will be constructed, rather than a simple list-of-strs
    substitutiuon alias being used. For example:
    .. code-block:: sh
        $ aliases['uuu'] = "echo ccc $(echo ddd)"
        $ aliases['uuu']
        ExecAlias('echo ccc $(echo ddd)\n', filename='<exec-alias:uuu>')
        $ uuu
        ccc ddd
  - The ``parse_aliases()`` function now requires the shell name.
  - ``ForeignShellFunctionAlias`` now inherits from ``ForeignShellBaseAlias``
    rather than ``object``.
 - Fixed:
  - Fixed issues where the prompt-toolkit v2 shell would print an extra newline
    after Python evaluations in interactive mode.
- update to version 0.8.4
 - Added:
  - Added the possibility of arbitrary paths to the help strings in ``vox activate`` and
    ``vox remove``; also updated the documentation accordingly.
  - New ``xonsh.aliases.ExecAlias`` class enables multi-statement aliases.
  - New ``xonsh.ast.isexpression()`` function will return a boolean of whether
    code is a simple xonsh expression or not.
  - Added top-level ``run-tests.xsh`` script for safely running the test suite.
 - Changed:
  - String aliases are no longer split with ``shlex.split()``, but instead use
    ``xonsh.lexer.Lexer.split()``.
  - Update xonsh/prompt/cwd.py _collapsed_pwd to print 2 chars if a directory begins with "."
  - test which determines whether a directory is a virtualenv
    previously it used to check the existence of 'pyvenv.cfg'
    now it checks if 'bin/python' is executable
 - Fixed:
  - Fixed issue with ``and`` & ``or`` being incorrectly tokenized in implicit
    subprocesses. Auto-wrapping of certain subprocesses will now correctly work.
    For example::
        $ echo x-and-y
        x-and-y
  - Fix EOFError when press `control+d`
  - fix no candidates if no permission files in PATH
  - Fixed interpretation of color names with PTK2 and Pygments 2.3.
  - Several ResourceWarnings: unclosed file in tests
  - AttributeError crash when using --timings flag
  - issue #2929
- update to version 0.8.3
 - Added:
  - Dociumentation paragrapgh about gow to run xonsh in Emacs shell
 - Changed:
  - Updated what pip requirements are needed to build the documnetaion
  - ``$XONSH_TRACEBACK_LOGFILE`` now beside strings also accepts ``os.PathLike``
    objects.
  - Updated vended version of ``ply`` to 3.11
  - Deprecation warnings now print from stacklevel 3.
 - Fixed:
  - Annotation assignment statements (e.g. ``x : int = 42``) are now supported.
  - Fixed error output wording for fg and bg commands
  - Flake8 errors
  - xonsh can now properly parse import statements with trailing comma within
    parentheses, e.g.::
      from x import (y, z,)
  - ResourceWarning: unclosed scandir iterator in imphooks.py
  - Removed use of deprecated ``inspect.formatargspec()`` for ``inspect.signature()``
  - ``Makefile`` directive that updates vended version of ``ply``
