3.0.30: 2022-06-27
------------------

New features:
- Allow zero-width-escape sequences in `print_formatted_text`.
- Add default value option for input dialog.
- Added `has_suggestion` filter.

Fixes:
- Fix rendering of control-shift-6 (or control-^). Render as '^^'
- Always wrap lines in the Label widget by default.
- Fix enter key binding in system toolbar in Vi mode.
- Improved handling of stdout objects that don't have a 'buffer' attribute. For
  instance, when using `renderer_print_formatted_text` in a Jupyter Notebook.
