	    hacks from code and tests.
	  - Code cleanup,
	    check PEP 8 conformity with `flake8` (exceptions in file tox.ini).
	* docutils/__main__.py
	  - New module. Support for ``python -m docutils``.
	    Also used for the ``docutils`` console script `entry point`.
	* docutils/core.py:
	  - Let `Publisher.publish()` print info and prompt when waiting for input
	    from a terminal (cf. https://clig.dev/#interactivity).
	  - Respect "input_encoding_error_handler" setting when opening a source.
	* docutils/io.py
	  - New function `error_string()`
	    obsoletes `utils.error_reporting.ErrorString`.

	  - Alias for the "myst" parser (https://pypi.org/project/myst-docutils).
	  - Use absolute module names in `_parser_aliases` instead of two
	    import attempts. (Keeps details if the `recommonmark_wrapper.py` module
	    raises an ImportError.)
	  - Prepend parser name to ImportError if importing a parser class fails.
	* docutils/parsers/commonmark_wrapper.py
	  - New module for parsing CommonMark input. Selects a locally installed
	    3rd-party parser (pycmark, myst, or recommonmark).

	  - Raise ImportError, if import of the upstream parser module fails.
	    If called from an `"include" directive`_,
	    the system-message now has source/line info.
	  - Adapt to and test with "recommonmark" versions 0.6.0 and 0.7.1.
	  .. _"include" directive: docs/ref/rst/directives.html#include

	  - Update PEP base URL (fixes bug #445),
	    use "https:" scheme in RFC base URL.
	  - Add `reporter` to `Directive` class attributes.
	* docutils/parsers/rst/directives/__init__.py

	* docutils/parsers/rst/roles.py
	  - Don't use mutable default values for function arguments. Fixes bug #430.
	* docutils/transforms/universal.py
	  - Fix bug #435: invalid references in `problematic` nodes
	    with report_level=4.

	* docutils/writers/_html_base.py
	  - Add "html writers" to `config_section_dependencies`. Fixes bug #443.

	* docutils/writers/html5_polyglot/__init__.py
	  - Add space before "charset" meta tag closing sequence.

	    after converting it to a "control" attribute of the <video> tag.

	* docutils/writers/pep_html/
	  - Use "https:" scheme in "python_home" URL default.
