xonsh 0.9.0 on Python PyPI

Added:

Implemented the following "bang command" bashisms: !$, $*, !^,
and !<str>. These are in addition to !!, which was already
implemented.
asciinema (terminal recorder) added in not threadable commands.
tput added in not threadable commands.
New color_tools.KNOWN_XONSH_COLORS frozenset.
New pyghooks.PYGMENTS_MODIFIERS mapping from color modifier names to
pygments colors.
New pyghooks.color_name_to_pygments_code() function for converting
color names into pygments color codes.

Changed:

Circle now runs black checks on contents of bundled xontribs
The black checks no longer skip some files buried deeper in the directory
tree.
Errors while formatting the prompt are highlighted for easier debugging.
Pygments styles only define the standard set of colors, by default.
Additional colors are computed as needed.
PTYs created for running threadable command have now size set to same size
than main terminal.
Update documentation pointing to the minimal required version of
Python (3.5).

Deprecated:

Removed:

pyghooks.KNOWN_COLORS is no longer needed or useful as pygments colors
are computed automatically.
style_tools.KNOWN_COLORS was never used, redundant with
pyghooks.KNOWN_COLORS and has thus been removed.

Fixed:

Fixed a DeprecationWarning that would show up during an import of MutableSet.
Fixed error with aliases composed of functions wrapped in functools.partial.
black formatted all xontribs
deleting a non existing environement variable with default value do nothing
instead of raising a exception trying to deleting it in existing values dict.
Fixed crash while converting ANSI color codes with leading zeroes
Fixed crash while parsing invalid ANSI color code
fix causing infinite loop when doing cat empty file
Fixed issue which occurs when user doesn't have access to parent directory and
xonsh scan all parents directory to find if we are in a Hg repository.
Fixed issue with pygments-cache not properly generating a cache the first
time when using prompt-toolkit when using ptk2.
This was due to a lingering lazy import of pkg_resources
that has been removed.
Minor update for Python v3.8.
Fixed a "'NoneType' object is not iterable" bug when looking up stty
in command cache.
The release tarball now includes all test files.
Arguments passed to python in 'scripts/xonsh' and in 'scripts/xonsh-cat' are
now passed by a portable hack in sh, not anymore by /usr/bin/env.
