Release 0.21 (2024-04-09)

• General:

  • Drop support for Python 3.7 and 3.8.

  • Provide rst2* "console_scripts" entry points (without the .py extension) instead of installing the rst2*.py front end tools in the binary PATH. [1]

• Output changes:

  HTML5:

  Use dpub-ARIA role "doc-footnote" (instead of ARIA role "note") for footnotes.

  LaTeX:

  Do not load the inputenc package in UTF-8 encoded LaTeX sources. (UTF-8 is the default encoding for LaTeX2e since 2018).

• Drop support for Python 2.7, 3.5, and 3.6.

• Output changes:

  HTML5:

  Wrap groups of footnotes in an <aside> for easier styling.

• After package installation, the CLI commands python -m docutils and docutils start the generic command line front end tool.

• Support parsing "Markdown" input with 3rd party parsers myst, pycmark, or recommonmark.

• The default values for the "pep-references", "rfc-base-url", and "python-home" configuration settings now use the "https:" scheme. The PEP-writer template's header is updated to fix links and resemble the header of official PEPs.

• Various bugfixes and improvements (see HISTORY).

Release 0.18.1 (2021-12-23)

• nodes.Node.traverse() returns a list again to restore backwards compatibility (fixes bug #431). Use nodes.Node.findall() to get an iterator.

• re-add module parsers.rst.directives.html (stub, emits deprecation warning and loads "Meta" directive from its new place at parsers.rst.directives.misc.)

• Small bugfixes (see HISTORY).

Release 0.18 (2021-10-26)

• Output changes:

  Identifiers:

  • During identifier normalization, leading number and hyphen characters are no longer stripped from a reference name, if the id_prefix setting is non-empty.

    Example:

    with --id-prefix="DU-", a section with title "34. May" currently gets the identifier key DU-may and after the change the identifier key DU-34-may.

  • The default value for the auto_id_prefix setting changed to %: "use the tag name as prefix for auto-generated IDs". Set auto_id_prefix to id for unchanged auto-IDs.

  HTML5:

  • Use the semantic tag <aside> for footnote text and citations, topics (except abstract and toc), admonitions, and system messages. Use <nav> for the Table of Contents.

  • Make "auto" table column widths the default: Only specify column widths, if the "widths" option is set and not "auto". The table-style setting "colwidths-grid" restores the current default.

  • Items of a definition list with class argument "details" are converted to details disclosure elements. Example:

    ..class:: details
    
    Summary
      This additional information should be hidden.

  • Do not add "compound-first", "compound-middle", or "compound-last" to elements nested in a compound. Use child selector and ":first-child", ":last-child" pseudo classes instead.

  • Use class value "backrefs" instead of "fn-backref" for a span of back-references.

  • Write footnote brackets and field term colons to HTML, so that they are present also without CSS and when copying text.

  • Move space character between section number and heading into "sectnum" span.

  math-output: html

  • Support more commands, fix mapping of commands to Unicode characters.

  • Scale variable sized operators and big delimiters with CSS.

  • Don't use <tt> element (deprecated in HTML5).

  • Use STIX fonts if available.

  legacy_class_functions setting default changed to "False", admonitions are now environments.

• New standard Docutils doctree node: <meta>.

• New configuration settings:

  • [latex writers] legacy_column_widths and

  • [html5 writer] image_loading.

• Removed files: iepngfix.htc and blank.gif (IE 6 workaround for s5_html).

• Removed sub-module: parsers.rst.directives.html (reversed in release 0.18.1).

• Removed function: utils.unique_combinations() (obsoleted by itertools.combinations()).

• Removed attributes:

  • HTMLTranslator.topic_classes: check node.parent.classes instead.

  • nodes.Text.rawsource: we store the null-escaped text in Text nodes since 0.16 so there is no additional information in the rawsource.

• Major refactoring and fixes/additions in docutils/utils/math/math2html.py and docutils/utils/math/latex2mathml.py (mathematical notation in HTML, cf. LaTeX syntax for mathematics).

• nodes.Node.traverse() returns an iterator instead of a list (reversed in release 0.18.1).

• Various bugfixes and improvements (see HISTORY).

  Fix spelling errors in documentation and docstrings. Thanks to Dimitri Papadopoulos.

• HTML5 writer:

  • New option embed_images.

  • Change the initial_header_level setting's default to "2", as browsers use the same style for <h1> and <h2> when nested in a section.

  • New optional style responsive.css, adapts to different screen sizes.

  • Move non-essential styling from minimal.css to plain.css rsp. responsive.css.

  • Show code line numbers as pseudo-elements so they are skipped when copying the code block from the page.

• LaTeX writer:

  • New configuration setting legacy_class_functions.

  • The special value "auto" for the graphicx_option setting is no longer supported (it never worked for xetex/luatex).

  • Styling commands using the legacy \docutilsrole prefix are now ignored. Use \DUrole.

  • Most helper commands and element definitions are now defined in the LaTeX package docutils.sty and only inserted in the document preamble if the stylesheet setting does not lists "docutils".

  • Remove legacy LaTeX stylesheet docutils-05-compat.sty.

Release 0.16 (2020-01-12)

Docutils 0.16.x supports Python 2.7 and Python >= 3.5 natively, without the use of the 2to3 tool.

  • Respect automatic table column sizing.

• docutils/writers/latex2e/__init__.py
