xonsh 0.8.2

on Python PyPI

Changed:

• Now there is only a single instance of string.Formatter() in the
  code base, which is called xonsh.tools.FORMATTER.

Fixed:

• f-strings (f"{expr}") are now fully capable of executing xonsh expressions.
  The one exception to this is that ![cmd] and !(cmd) don't work because
  the ! character interferes with Python string formatting. If you need to
  run subprocesses inside of f-strings, use $[cmd] and $(cmd) instead.
• Fixed occasional "no attribute 'settitle' error"
