  • New input formats: endnotexml (EndNote XML bibliography), ris (RIS bibliography).

  • A RIS bibliography file may now be used with --citeproc.

  • Citeproc: Allow a formatted bibliography to be placed in metadata fields via a Div with class refs (#7969, #526). Thus, one can include a metadata field, say refs, whose content is an empty div with id refs, and the formatted bibliography will be put into this metadata field. It may then be interpolated into a template using the variable refs.

  • Ensure that you don’t get PDF output to terminal. -t pdf now behaves like -t docx and gives an error unless the output is redirected.

  • --version now prints hslua version (#7929) and Lua version (#7997, Albert Krewinkel).

  • Change --metadata-file parsing so that, when the input format is not markdown or a markdown variant, pandoc’s markdown is used (#6832, #7926). When the input format is a markdown variant, the same format is used. Reason for the change: it doesn’t make sense to run the markdown parser with a set of extensions designed for a non-markdown format, and this dramatically limits what people can do in metadata files.

  • Trim whitespace from math in --webtex (#7892). This fixes problems with –webtex and markdown output, when display math starts or ends with a newline.

  • New exported module Text.Pandoc.Readers.EndNote, exporting readEndNoteXML, readEndNoteXMLCitation, and readEndNoteXMLReferences. [API change]

  • --self-contained: issue warning rather than failing with an error if a resource can’t be found (#7904).

  • New exported module, Text.Pandoc.Readers.RIS, exporting readRIS (#7894).

  • LaTeX reader:

    • Handle subequations as inline math environment (#7883).
    • Rudimentary support for vbox (#7939).
    • Support \today (#7905).
    • Handle \label and \ref for footnotes (#7930).
    • Allow inline groups starting with \bgroup (#7953).
    • Use custom TokStream that keeps track of whether macros are expanded. This allows us to improve performance a bit by avoiding unnecessary runs of the macro expansion code (e.g. from 24 ms to 20 ms on our standard benchmark).
    • Further optimizations for inline parsing.
    • Better handling of \usepackage. If the package is local but causes parse errors, parse everything up to the error and skip the rest. Issue a CouldNotParseIncludeFile warning indicating that parsing failed at that point.
    • Text.Pandoc.Readers.LaTeX.Parsing: Monoid and Semigroup instances for TokStream.

  • HTML reader:

    • Give warnings and emit empty note when parsing <a epub:type="noteref"> and the identifier doesn’t correspond to anything in the note table (#7884). Previously we just silently skipped these cases.
    • Fix parsing of epub footnotes (#7884).

  • DocBook reader:

  • DokuWiki reader:

    • Add DokuWiki table alignment (#5202, damon-sava-stanley).

  • RST reader:

    • Fix treatment of headerless simple tables (#7902).
    • Wrap math in Span to preserve attributes (#7998, Albert Krewinkel). Math elements with a name, classes, or other fields are wrapped in a Span with these attributes.

  • JATS reader:

    • Improve handling of fn-group elements (#6348, Albert Krewinkel). Footnotes in <fn-group> elements are collected and re-inserted into the document as proper footnotes in the place where they are referenced.
    • Handle pub-date (#8000).
    • Support PMID, DOI, issue in citations (#7995).
    • Improve refs parsing. Handle issn and isbn; use simpler form for issued date.
    • Strip ‘ref-’ from ref id in constructing CSL id. This allows better round-tripping, because the JATS writer adds the ref- prefix to the citation id to get the ref element’s id.

  • Org reader:

    • Allow “:” in property drawer keys (Lucas V. R). Any non-space character is allowed as property drawer key, including “:” itself (so it is not really a delimiter). The real delimiter is a space character, so in a drawer like 

      :PROPERTIES:
::k:ey:: value
:END:

      “:k:ey:” is a key with value “value”.

    • Allow comments above property drawer.

    • More flexible LaTeX environments (Lucas V. R).

    • Handle #+bibliography: as metadata so that it can work with --citeproc.

    • Parse #+print_bibliography: as Div with id refs.

    • Allow multiple #+bibliography:.

  • Markdown reader:

    • Allow one-column pipe tables with pipe on right (#7919).
    • Remove restriction on identifiers, so they no longer need to begin with a letter (#7920).

  • Docx reader:

    • Enable citations extension for docx reader (#7840). When enabled, Zotero, Mendeley, and EndNote citations embedded in a docx are parsed as native pandoc citations. (When disabled, the generated citation text and bibliography are passed through as regular text.) The bibliography generated by the plugin is suppressed. Instead, bibliographic data embedded in citation items is added to the references metadata field so that it can be used with --citeproc.

  • Docbook writer:

    • Interpret links without contents as cross-references (#7360, Jan Tojnar). Links without text contents are converted to <xref> elements. DocBook processors will generate appropriate cross-reference text when presented with an xref element.

  • Docx writer:

    • Single numbering ID for examples (#7895, mjfs). This change ensures that example list items all belong to a single number sequence, so that if items are added or deleted in a word processor, the other items will renumber automatically.
    • Add bookmark with table id to table (#7989, Nikolai Korobeinikov, #7285). This allows tables with ids to be linked to.

  • Ipynb writer:

    • Handle metadata better (#7928). Previously we used the markdown writer to render metadata. This had some undesirable consequences (e.g. en dash expanded to -- when smart enabled), so now we use the plain writer.

  • LaTeX writer:

    • Avoid extra space before \CSLRightInline (#7932).
    • Add scrreport to chaptersClasses (#6168, ivardb).
    • Support page,trim,clip attributes on images (#7181).
    • Add () after booktabs rules (#8001). These commands take optional arguments with () and [], which can lead to problems if the content of the table cell begins with these characters.

  • RST writer:

    • Support all standard metadata (“bibliographic”) fields.

  • HTML writer: performance improvements.

  • Org writer:

    • Stop indenting property drawers, quote blocks (#3245, Albert Krewinkel). This follows the current default org-mode behavior.

  • Markdown writer:

    • Move table-related code into submodule (Albert Krewinkel).
    • Don’t produce redundant header identifier when the gfm_auto_identifiers extension is set (#7941).
    • Update escaping rules for \. We now escape \ only if raw_tex is enabled or it is followed by a non-alphanumeric.

  • JATS writer:

    • Encode author “others” as <etal/> (Albert Krewinkel). Citeproc adopted the BibTeX convention to use the author name “others” when there are additional authors that are not named. JATS uses the <etal> element for this.
    • Avoid doubled ref-list element (#7990). Previously when generating JATS with the element_citations extension enabled, the references were put in a doubly-nested ref-list element (<ref-list><ref-list>...).
    • Keep edition info in element citations (#7993, Albert Krewinkel).
    • Fix handling of CSL variable ‘page’ (not ‘pages’ as we had before). It should go to ‘lpage’ and ‘rpage’, not ‘page-range’.

  • EPUB writer: refactor for clarity (#7991, Jonathan Dönszelmann, Ola Wolska, Ivar de Bruin, Jaap de Jong).

  • Custom writer (Albert Krewinkel):

    • Support new-style Writer function (Albert Krewinkel). See the documentation for custom writers for details.
    • Produce stacktrace if Writer function fails

  • Text.Pandoc.Logging: add CouldNotParseIncludeFile constructor for LogMessage [API change].

  • Text.Pandoc.Shared:

    • Put id attributes on TOC entries (#7907, damon-sava-stanley). Naming scheme of id is “toc-” + id of linked to header/section. Effects HTML, Markdown, Powerpoint, and RTF.
    • Define ordNub as alias for nubOrd from containers package (#7963, Albert Krewinkel).
    • Export ensureValidXmlIdentifiers. This function changes identifiers that don’t start with letters, and internal links to these identifiers, making them compatible with XML standards. The change is simple: we add id_ to the front. There is potential for duplication if there are already id_... identifiers defined, but this seems rare enough not to worry too much about.

  • Ensure that valid XML identifiers are used in Docbook, EPUB, FB2, HTML4, S5, Slidy, Slideous, ICML, ODT, TEI writers. Thus, if you convert [anchor]{#1} and [link to](#1), id_1 will be used instead of 1 for the identifier.

  • Lua (Albert Krewinkel).

    • Add module pandoc.layout to format and layout text.
    • Move custom writer code into Lua hierarchy.
    • Use pandoc-lua-marshal 0.1.5.
    • Allow any type of callable object as argument to List functions filter, map, and find_if. These previously required the argument to be of type function, which was too restrictive.
    • Inline: the type of Image captions is now Inlines instead of List.
    • Allow passing Sources to pandoc.read (#8002).

  • Text.Pandoc.PDF:

    • Restore wkhtmltopdf as default pdf engine for HTML (Albert Krewinkel).
    • Allow custom writer as format if engine is explicitly specified (#7898, Albert Krewinkel). Note that it may be necessary to explicitly specify a template on the command line.

  • Text.Pandoc.MediaBag: improve detection of absolute paths (#7881).

  • Text.Pandoc.Extensions:

    • Remove raw_tex extension from list of commonmark extensions, and from the commonmark_x defaults. commonmark doesn’t parse raw TeX, and it doesn’t make sense to write it if we don’t parse it.
    • Remove native_divs from allowed gfm extensions (#7965). This allows <div> to be suppressed using -raw_html. Previously native_divs was enabled but could not be suppressed, because it was not in the list of available extensions for commonmark-based formats.

  • Text.Pandoc.Parsing:

    • Partition module into (internal) submodules (#7962, Albert Krewinkel).

    • Unify grid table parsing (#7971, Albert Krewinkel). Grid table parsing in Markdown and RST are updated use the same functions. Functions are generalized to meet requirements for both formats. This change also lays the ground for further generalizations in table parsers, including support for advanced table features. [API change] in Text.Pandoc.Parsing:

      • Parse results of functions tableWith' and gridTableWith' are now a mf TableComponents instead of a quadruple of alignments, column widths, header rows and body rows.
      • Additional exports from Text.Pandoc.Parsing: tableWith', TableComponents, TableNormalization, toTableComponents, toTableComponents'.

  • Text.Pandoc.XML.Light: add versions of the parsers that allow specifying a custom entity map. Exports new functions: parseXMLElementWithEntities, parseXMLContentsWithEntities [API change].

  • Text.Pandoc.Writers.GridTable: improve module documentation (Albert Krewinkel).

  • Text.Pandoc.Parsing.GridTable: simplify column handling code (Albert Krewinkel).

  • Text.Pandoc.MIME: Add mime type for mkv extension (#7181).

  • Text.Pandoc.Asciify: Fix regression with ascii_identifiers and Turkish undotted i (#8003).

  • Relax upper bound for hslua, allow hslua-2.2. (#7929) Lua 5.4 is used by default after this is merged. Packagers may still include Lua 5.3 instead by building pandoc with --constraint='hslua <2.2'. Differences between 5.3 and 5.4 should not generally affect pandoc Lua filters. See list of incompatible changes here: https://www.lua.org/manual/5.4/manual.html#8.1

  • JATS template: allow multiple licenses (Albert Krewinkel).

  • LaTeX template:

    • Skip \babelprovide if babel-lang is empty (#7945) to avoid an error.
    • Move hyperref near end of preamble (#5811). It now comes after header-includes and right before title, author, date, abstract. Note: Users who presuppose hyperref in their header-includes will now have to add \usepackage{hyperref} to their header-includes to make it available there. (The redundant \usepackage will do no harm in this case.)
    • Remove special redefinition of \sout. This used to be necessary to avoid problems with hyperref, when headings contain strikeout text, but it does not seem to be necessary any more (tested).

  • Tests: improve location reporting of failing tests (Albert Krewinkel).

  • Add tests for idempotency of makeSections (#7950).

  • Add armhf support in linux build script (#7944, Tony).

  • Use latest pandoc-types, so that toJSONFilter will work with Meta and MetaValue.

  • Use latest doclayout, texmath, commonmark, citeproc.

  • INSTALL.md: add reference to install via winget (#7951, Guriy Samarin).

  • MANUAL.txt:

    • Document way to get list in block quote in slide shows (#7916).
    • Minor changes to security section.
    • Note that smart works for html input.
    • Fix typos (#7934, Dimitris Apostolou).
    • Fix documentation for citations and org mode.
    • Remove claim that --self-contained does not work with --mathjax (#682).

  • doc/org.md: remove obsolete citations section. This mostly described citation formats we no longer support.

  • doc/lua-filters.md: Fix typo (#7981, Mario Lang).

  • Makefile: Use cabal for default build

  • Add lua53 cabal flag. It is false by default. If set to true, compile with hslua 2.1 and Lua 5.3, otherwise hslua 2.2 and Lua 5.4.
