Release 0.22 (2026年07月29日)
=========================
* General
 - We have started to add type hints to Docutils (feature-request #87).
 This will be a complex programme of work and as such,
 for the time being, these type hints are "provisional"
 and should not be relied upon.
 By default, the Python interpreter treats type hints as annotations.
 Python>= 3.10 is required with active type hints
 (``typing.TYPE_CHECKING == True``).
* docs/ref/docutils.dtd
 - Allow multiple <term> elements in a <definition_list_item>.
 Fixes feature-request #60
 - The first element in a <figure> may also be a <reference>
 (with nested "clickable" <image>).
* docutils/core.py
 - Removed `Publisher.setup_option_parser()` (internal, obsolete).
 - Allow a string value (component name or alias) in the "reader",
 "parser", and "writer" arguments of `Publisher.__init__()` and
 the `publish_*()` convenience functions.
* docutils/frontend.py
 - Drop short options ``-i`` and ``-o`` for ``--input-encoding``
 and ``--output-encoding``.
 - Change the default input encoding from ``None`` (auto-detect) to "utf-8".
 - Change the default value of the root_prefix_ setting to the empty string
 (no change to the behaviour).
* docutils/io.py
 - Change the default input encoding from ``None`` (auto-detect) to "utf-8".
* docutils/nodes.py
 - Raise TypeError if the "rawsource" argument in `Element.__init__()`
 is an `Element` instance.
 Catches errors like ``nodes.hint(nodes.paragraph())``.
 - New element category classes `SubStructural` and `PureTextElement`.
 - Fix element categories.
 - New method `Element.validate()`: raise `nodes.ValidationError` if
 the element does not comply with the "Docutils Document Model".
 Provisional.
 - New "attribute validating functions"
 convert string representations to correct data type,
 normalize values, and
 raise ValueError for invalid attribute names or values.
 - New function `parse_measure()`.
 - Removed `Element.set_class()`.
 - Downgrade "duplicate ID" message level from SERIOUS to ERROR.
 - Fix recursion in `Element.get_language_code()`.
 - Do not insert <system_message> elements for duplicate explicit targets
 if this results in an invalid doctree (cf. bug #489).
 - Don't include a "backlink" reference in system messages, if the
 referenced element is an external target (not visible in the output).
 - Don't invalidate indirect targets with duplicate name, if they refer to
 the same refname (similar to external targets refering to the same URI).
* docutils/parsers/docutils_xml.py
 - New parser for Docutils XML sources. Provisional.
* docutils/parsers/recommonmark_wrapper.py
 - New method `Parser.finish_parse()` to clean up (before validating).
* docutils/parsers/rst/languages/
 - Remove mistranslations of the "admonition" directive name.
* docutils/parsers/rst/languages/en.py
 - Add alias "rst-class" for the "class" directive to improve the
 compatibility with Sphinx.
* docutils/parsers/rst/directives/__init__.py
 - Support CSS3 `length units`_. Fixes feature-request #57.
* docutils/parsers/rst/directives/images.py
 - New option "figname" for the "figure" directive.
 Fixes feature-request #44.
* docutils/parsers/rst/directives/misc.py
 - Pass the included file's path to the parser when the
 "include" directive is used with :parser: option.
 Enables system messages with correct source/line info.
 - Pass default settings to custom parser for included file.
* docutils/parsers/rst/directives/references.py
 - Remove "name" from `TargetNotes.option_spec`.
 The "target-notes" directive generates one footnote element per
 external target but "name" must be unique across the document.
 So far, the name was silently dropped.
* docutils/parsers/rst/directives/tables.py
 - Removed `CSVTable.decode_from_csv()` and `CSVTable.encode_from_csv()`.
 Not required with Python 3.
* docutils/parsers/rst/roles.py
 - Renamed `normalized_role_options()` to `normalize_options()`
 (it is now also used for directive options).
* docutils/parsers/rst/states.py
 - Raise warning for empty footnotes and citations.
 - Add source and line info to <enumerated-list> elements.
 Fix line number of "start value not ordinal-1" INFO message.
 - Change section handling to not rely on exceptions and reparsing.
 Based on patch #213 by Arne Skjærholt.
 Fixes bug #346 (duplicate System Messages).
 - Use `types.SimpleNamespace` instead of a local definition for
 the auxilliary class `states.Struct`.
 - Warn about duplicate name in references with embedded internal targets.
 Fixes bug #502.
 - "Downgrade" targets generated from hyperlink references with embedded
 URI or alias from explicit to implicit (cf. bug #502).
* docutils/readers/__init__.py:
 - Deprecate "parser_name" argument of `Reader.__init__()`.
* docutils/transforms/frontmatter.py
 - Update `DocInfo` to work with corrected element categories.
* docutils/transforms/misc.py:
 - Fix for `misc.Transitions`: report an error if a <transition> element
 follows a <meta> or <decoration> element as this is invalid
 according to ``docutils.dtd``.
* docutils/transforms/references.py
 - New transform `CitationReferences`. Marks citation_references
 as resolved if BibTeX is used by the backend (LaTeX).
* docutils/transforms/writer_aux.py
 - Removed `Compound` transform.
* docutils/transforms/references.py
 - Make `AnonymousHyperlinks` transform idempotent.
* docutils/transforms/universal.py
 - `Messages` transform now also handles "loose" system messages
 generated by the parser.
* docutils/utils/__init__.py
 - Removed `Reporter.set_conditions()`.
 Set attributes via configuration settings or directly.
* docutils/utils/_roman_numerals.py
 - New implementation or Roman numeral support.
 Replaces the local copy of the roman.py package.
* docutils/utils/error_reporting.py
 - Removed. Obsolete in Python 3.

 source path and the internal `source` attribute is None.
* docutils/writers/html4css1/__init__.py
 - Keep default math_output_ value "HTML math.css".
 - Add "px" to unitless table "width" values.
* docutils/writers/latex2e/__init__.py
 - `LaTeXTranslator.to_latex_length()`:
 Handle CSS3 `length units`_.
 Remove optional argument `pxunit` (ignored since at least 2012).
 Drop trailing zeroes from length values.
 Move XeTeX-specific code to the "xetex" writer.
 - Don't wrap references with custom reference-label_ in
 a ``\hyperref`` command.
 - Mark the main language when loading "babel".
 - Provide an "unknown_references_resolver" (cf. `docutils/TransformSpec`)
 for citation references resolved with BibTeX (cf. `use_bibtex`_ setting).
 - Support SVG image inclusion with the "svg" LaTeX package (see the
 `stylesheet`__ configuration setting). Solves feature-request #83
 - Add "template" to the parts returned by `Writer.assemble_parts()`.
 - Use standard `dict` for `LaTeXTranslator.requirements`
 and `LaTeXTranslator.fallbacks`.
 - Use <document> "title" attribute in pdfinfo.
 - Encode <meta> element content in pdfinfo.
 - Improve formatting of docinfo fields.
 - `LaTeXTranslator.pop_output_collector()` now returns the popped list.
 - Replace `Writer.bibtex_reference_resolver()` with a transform.
 - `LaTeXTranslator.visit_inline()` now inserts labels for the

 hyperlinks and backlinks). Avoids "empty anchor" warnings.
 - Fix target position and re-style system messages.
 - Don't merge paragraphs if there is a target between them.
 .. _reference-label: docs/user/config.html#reference-label
 __ docs/user/config.html#stylesheet-latex-writers
* docutils/writers/latex2e/docutils.sty
 - Replace use of ``\ifthenelse{\isundefined...`` (from "ifthen.sty")
 with the eTeX primitive ``\ifdefined``.

Release 0.21 (2024年04月09日)
=========================
* General
 - Drop support for Python 3.7 and 3.8.
 - Updated build system to use Flit_ (patch #186 by Adam Turner).
 Removed ``setup.py``.
 - Provide ``rst2*`` "console_scripts" `entry points`_

 .. _Flit: https://github.com/pypa/flit/
* docs/ref/docutils.dtd
 - The <image> element accepts a new attribute "loading".
 - Fix definitions (no change to actual behaviour):
 * The <math_block> element uses the attribute "xml:space".
 * The <raw> element may contain text only (no inline elements).
 * The <topic> element uses the "depth" and "local" attributes to
 store "contents" directive options when used as placeholder for a
 generated table of contents (LaTeX writers with `use_latex_toc`_
 setting).

 Reference names (``%refname.type`` and ``%refnames.type``)
 are whitespace-normalized but **not** always downcased.

 Improve error reporting.
 - Sort ħ (`\hslash`) as "mathord", not "mathalpha".
* docutils/utils/math/latex2mathml.py
 - Generate "MathML Core" to fix rendering with Chromium/Android.
 Use CSS rules instead of the deprecated "columnalign" attribute

 problems on SourceForge (``libssl.so.2`` unavailable?).
 - Added the "role" directive for declaring custom interpreted text
 roles.
* docutils/parsers/rst/directives/parts.py:
 - The "contents" directive does more work up-front, creating the
 "topic" and "title", and leaving the "pending" node for the
 transform. Allows earlier reference resolution; fixes subtle bug.
* docutils/parsers/rst/languages/af.py: Added to project; Afrikaans
 mappings by Jannie Hofmeyr.

 references. This is because we are now adding a "name" attribute to
 references in addition to targets. Note sure if this is correct!

 transformer in resolve_indirect_target. This allows the
 unknown_reference_resolvers to keep around indirect targets which
 docutils doesn't know about.
 - Added specific error message for duplicate targets.
* docutils/transforms/universal.py:
 - Added FilterMessages transform (removes system messages below the
 verbosity threshold).

 - Added assemble_parts() method to the Writer class to allow for
 access to a documents individual parts.
 - Documented & set default for ``Writer.output`` attribute.
* docutils/writers/html4css1.py:
 - Fixed unicode handling of attribute values (bug 760673).
 - Prevent duplication of "class" attribute values (bug report from
 Kirill Lapshin).
 - Improved table grid/border handling (prompted by report from Bob
 Marshall).
 - Added support for table titles.
 - Added "<title />" for untitled docs, for XHTML conformance; thanks
 to Darek Suchojad.
 - Added functionality to keep track of individual parts of a document
 and store them in a dictionary as the "parts" attribute of the writer.
 Contributed by Reggie Dugard at the Docutils sprint at PyCon DC 2004.
 - Added proper support for the "scale" attribute of the "image"
 element. Contributed by Brent Cook.
 - Added ``--initial-header-level`` option.
 - Fixed bug: the body_pre_docinfo segment depended on there being a
 docinfo; if no docinfo, the document title was incorporated into
 the body segment. Adversely affected the publish_parts interface.
* docutils/writers/latex2e.py:
 - Changed default stylesheet to "no stylesheet" to avoid latex complaining
 about a missing file.
 - Added options and support: ``--compound-enumerators``,
 ``--section-prefix-for-enumerators``, and
 ``--section-enumerator-separator``. By John F Meinel Jr (SF patch
 934322).
 - Added option ``--use-verbatim-when-possible``, to avoid
 problematic characters (eg, '~' in italian) in literal blocks.
 - It's now possible to use four section levels in the `book` and
 `report` LaTeX document classes. The default `article` class still has
 three levels limit.
* docs/config.txt: "Docutils Configuration Files", added to project.
 Moved config file entry descriptions from tools.txt.
* docs/tools.txt:
 - Moved config file entry descriptions to config.txt.

 supported.
* tools/docutils.conf:
 - Updated for configuration file reorganization.
* tools/rst2html.py:

Release 0.2 (2002年07月31日)
========================
General:
- The word "component" was being used ambiguously. From now on,
 "component" will be used to mean "Docutils component", as in Reader,
 Writer, Parser, or Transform. Portions of documents (Table of
 Contents, sections, etc.) will be called "document parts".
- Did a grand renaming: a lot of ``verylongnames`` became
 ``very_long_names``.
- Cleaned up imports: no more relative package imports or
 comma-separated lists of top-level modules.
- Added support for an option values object which carries default
 settings and overrides (from command-line options and library use).
- Added internal Unicode support, and support for both input and
 output encodings.
- Added support for the ``docutils.io.IO`` class & subclasses.
Specific:
* docutils/__init__.py:
 - Added ``ApplicationError`` and ``DataError``, for use throughout
 the package.

 the ``supports`` method.
 - Added ``__version__`` (thus, ``docutils.__version__``).
* docutils/core.py:
 - Removed many keyword parameters to ``Publisher.__init__()`` and
 ``publish()``; bundled into an option values object. Added
 "argv", "usage", "description", and "option_spec" parameters for
 command-line support.
 - Added ``Publisher.process_command_line()`` and ``.set_options()``
 methods.
 - Reworked I/O model for ``docutils.io`` wrappers.
 - Updated ``Publisher.set_options()``; now returns option values
 object.
 - Added support for configuration files (/etc/docutils.conf,
 ./docutils.conf, ~/.docutils).
 - Added ``Publisher.setup_option_parser()``.
 - Added default usage message and description.
* docutils/frontend.py: Added to project; support for front-end
 (command-line) scripts. Option specifications may be augmented by
 components. Requires Optik (http://optik.sourceforge.net/) for option
 processing (installed locally as docutils/optik.py).
* docutils/io.py: Added to project; uniform API for a variety of input
 output mechanisms.
* docutils/nodes.py:

 package, with added option groups and other modifications. The use
 of this module is probably only temporary.
* docutils/statemachine.py:
 - Added ``runtime_init`` method to ``StateMachine`` and ``State``.

 - In ``string2lines()``, changed whitespace normalizing translation
 table to regexp; restores Python 2.0 compatibility with Unicode.
