2.0.8:

Bug fixes:

  down in some applications after some time (especially if there is a refresh
  interval).
- Make print_container utility work if the input is not a pty.

New features:
- Underline non breaking spaces instead of rendering as '&'.
- Added mouse support for radio list.
- Support completion styles for READLINE_LIKE display method.
- Accept formatted text in the display text of completions.
- Added a FuzzyCompleter and FuzzyWordCompleter.
- Improved error handling in Application (avoid displaying a meaningless
  AssertionError in many cases).
