Add mdoc as input format (Evan Silberman). This change introduces a reader for mdoc, a roff-derived semantic markup language for manual pages. This reader has been developed almost exclusively against mandoc’s documentation and implementation of mdoc as a reference, and the real-world manual pages tested against are those from the OpenBSD base system. Of ~3500 manuals in mdoc format shipped with a fresh OpenBSD install, 17 cause the mdoc reader to exit with a parse error. Any further chasing of edge cases is deferred to future work.

New module: Text.Pandoc.Readers.Mdoc, exporting readMdoc [API change].

Issue warnings for duplicate YAML metadata keys (#10312).

Ensure that --sandbox affects --embed-resources. Previously it did not (contrary to what was implied by the manual), which means that an image with URL /etc/passwd would leak an encoded version of that file to HTML output with --self-contained or --embed-resources, even if --sandbox was used. Thanks to Samuel Mortenson for pointing out the issue.

Text.Pandoc.App.OutputSettings: add sandbox' function. This computes the sandboxed files from Opt and avoids code repetition.

Docx reader:

• Parse index references as empty spans with attributes (#10171). Attributes included are entry, and optionally bold, italic, yomi, see.
• Don’t create multiple paragraphs for title or subtitle (#10359). If there are multiple paragraphs with Title or Subtitle style, use only the first for metadata.
• Handle case where Zotero itemData has different id from the citationItem id. In this case we use the citationItemId in the bibliography as well, overriding the referenceId in the itemData (#10366).

LaTeX reader:

• Put parsed minipage in specially marked Div (#10266).

HTML reader:

• Parse footnotes defined by dpub-aria roles (#5294).

MediaWiki reader:

• Fix indented tables with caption (#10390).
• Fix parsing of col/rowspan (#6992).

Typst reader:

• Avoid generating empty paragraphs.
• Support underparen, overparen.
• Fix #quote attribution. If attribution is not present, don’t print the -- (#10320).
• Fix typo in unicode code point for em dash (see #10320).

Commonmark reader:

• implicit_figures should check for empty caption and not produce an implicit figure in this case (#10429).

RST reader:

• Use a new one-pass parsing strategy. Instead of having an initial pass where we collect reference definitions, we create links with target ##SUBST##something or ##REF##something or ##NOTE##something, and resolve these in a pass over the parsed AST. This allows us to handle link references that are not at the top level (#10281).
• Ignore newlines in URL in explicit link (#10279).
• Handle block level substitutions.
• Support :file: on raw directive (#8584).
• Implement option lists (#10318).
• Avoid putting metadata in Para (#7766). Create MetaInlines when possible, just as with markdown input. MetaBlocks is still used when there are multiple paragraphs or non-paragraph content. This change also affects field lists.
• Fix linked substitutions (#6588). E.g. |Python|_.
• Support inline anchors (#9196).
• Explicit links define references (#5081). For example, Go to `g`_ `g <www.example.com>`_. should produce two links to www.example.com.

EPUB writer:

• Use standardized filename for cover image instead of the original name (#10404). This avoids problems with e.g. filenames containing spaces.

Markdown writer:

• Issue INFO warning when not rendering table, e.g., when raw_html is disabled and the table can’t be fit into a supported markdown table format (#10407).
• Respect empty LineBlock lines in plain output (Evan Silberman). The plain writer behaved as a markdown variant with Ext_line_blocks turned off, and so empty lines in a line block would get eliminated.

LaTeX writer:

Ensure that beamer footnotes go on frame, not column (#5769).

HTML writer:

• Unwrap empty incremental divs (#10328, Albert Krewinkel). Divs are unwrapped if the only purpose of the div seems to be to control whether lists are presented incrementally on slides.

Typst writer:

• Make template sensitive to a page-numbering variable (#10370). This can be set to an empty string (or, in metadata, to false) for no page numbers.
• Make smart extension work (#10271). If smart is not enabled, a command in the default template will disable smartquote substitutions. When smart is enabled, render curly apostrophes as straight and escape straight apostrophes. When smart is disabled, render curly apostrophes as curly and don’t escape straight apostrophes. Similarly for quotes, em and en dashes. This should give more idiomatic typst output, with fewer unnecessary escapes.

ANSI writer:

• Respect empty LineBlock lines (Evan Silberman).

JATS writer:

• Correct spelling of suppress attribute (#10350, Andreas Deininger).

Typst template:

• Remove definitions.typst partial.
• Remove unnecessary definition of endnote.
• Incorporate the one remaining definition into default.typst.
• Use typst 0.12 code for two column layout (#10294, Luis Rivera).
• Note: the new templates presuppose typst 0.12; if you try to use an earlier version of typst, an error will be raised.

LaTeX/Beamer template:

• Split fonts.latex partial into two parts: fonts.latex and font-settings.latex.
• In beamer template, load beamer theme between fonts.latex and font-settings.latex. This allows a theme (such as metropolis) to set its own default font, while still allowing the user to override it. This fixes a regression in pandoc 3.5 (#10297).
• Note: Users who have custom templates based on pandoc 3.5 templates will need to add font-settings.latex() after fonts.latex() in the latex template. In a beamer template, the beamer theme-setting code needs to be moved between these two partials.

ConTeXt template: Ensure that font names don’t wrap (#10305).

epub.css: remove background-color (#10264, Suraj Patil). With this greyish background color, epubs look bad on a Kindle (#10263).

Text.Pandoc.ImageSize: add WebP support (Evan Silberman, #10397). Add Webp constructor on ImageType [API change].

Text.Pandoc.Readers.Roff and a new unexported module Text.Pandoc.Readers.Roff.Escape: parameterize Roff escaping (Evan Silberman) [API change]. This allows code to be reused between the mdoc and man readers, despite the differing Token types.

Text.Pandoc.PDF:

• PDF via LaTeX: always do max runs if toc is present (#10308). The old method (checking to see if toc hash had changed) is not completely reliable.
• Use .source extension, not .html, in toPdfViaTempFile (#10314).

Text.Pandoc.Logging: add YamlWarning constructor to LogMessage [API change] (#10312).

Text.Pandoc.Format: remove duplicate typst entry (#10388, Caleb Mclennan).

Fix a typo in the ua.yaml localization for ‘See’ (Jens).

Lua subsystem (Albert Krewinkel):

• Remove prefixes from Lua type names (#8574). Lua type names were inconsistent with regard to the use of prefixes; all prefixes are removed now, and Lua types now have the same name as the Haskell types. The use of app-specific prefixes is suggested by the Lua manual to avoid collisions. However, this shouldn’t be a problem with pandoc, as it cannot be used as a Lua package.

doc/libraries.md: Add newly developed Haskell packages. Sort list alphabetically (Albert Krewinkel).

doc/lua-filters.md: document pandoc.List:iter method (Albert Krewinkel). List objects have a new function iter that returns an iterator function that returns the next list item on each call.

MANUAL.txt:

• Clarify what the example of YAML EPUB metadata shows (#10405).
• Fix typo in template syntax (#10265, Pascal Wagler).
• Update manual with information on openxml template (#10273).
• Clarify that --variable can only assign string values (#10298).

Fix comments in TEI writer referring to DocBook (#10430, Evan Silberman).

Fix several typos in documentation (#10349, Andreas Deininger).

Allow Diff 1.0.

Add font-settings.latex partial to pandoc.cabal (#10379).

Bump upper bound for data-default.

Use latest typst, texmath, pandoc-lua-marshal, commonmark-pandoc, commonmark-extensions, skylighting, skylighting-format-blaze-html.
