Report the location of errors in defaults files (#8759, Andrzej Rybczak). An invalid value in a defaults file gave an error at the start of the file, with no indication of the field. The error now names the option and points at its value.

Use yamlet for YAML parsing. Pandoc parsed YAML with the yaml package, which depends on the C library libyaml. It now uses yamlet, a pure Haskell YAML 1.2 parser. Values still go through the existing aeson instances. Note these behavior changes:

• yes, no, on, off, y and n are strings, not booleans, as in YAML 1.2.
• YAML errors now show the file, the line and the column, with the offending line. In metadata blocks the line is the line in the document.
• Duplicate keys in a mapping are an error. They were a warning.
• .5, .inf and .nan are numbers.

Docx reader:

• Read w:fldSimple fields (#11944, Aslak Hellesøy).
• Keep grid columns that have no width (#11989, Patrick Creighton). w:w is optional on w:gridCol, but elemToTblGrid skipped the grid columns that had none. The table then had fewer columns than its rows had cells, and the extra cells were dropped. Every grid column is now kept. If any of them has no (readable) width, all columns get the default width.
• Fix namespaces in notes and comments (#11991, Patrick Creighton). The contents of footnotes, endnotes and comments were read with the namespace prefixes declared in word/document.xml rather than in their own parts.
• Records the indentation of each list level and track the open list levels; an unnumbered paragraph whose left indentation matches the text indentation of an open level is treated as a continuation of that level’s current item, rather than as a block quote (cf. #9197).
• Recover from fields with a missing instruction (#11943, enieuwy). This fixes a bug that could lead to content being omitted.
• Fix regression (from 3.11) in parsing column widths (#11969). The regression caused only the first column to get assigned its alignment; every other column received default alignment. In addition, in 3.11 alignment was taken from the header row if present; this changed behavior from earlier versions, which took it from the first body row. We revert to the earlier behavior, using the header row only if there are no body rows. It’s common for the header to have different alignment than the rest.
• Keep tracked paragraph marks inside notes (#11971, Aslak Hellesøy).

RST reader:

• Allow inline markup and bare links after :, /, ', ", < (Wleeaf). Fixes a regression since 3.2.1; these characters could no longer precede an inline markup start-string or a bare URI or email address, although the reStructuredText spec allows them. Also implement the rule that a start-character between an opening character and its closing counterpart, as in (*) or "*", does not trigger inline markup.

RTF reader:

• Fix tokenization bug (#11981). We were consuming certain symbols after \uNNNN during tokenization. This led to an extra character being consumed as the “fallback,” so letters went missing after encoded unicode characters.

LaTeX reader:

• Detect macro expansion loops across doMacros calls (#11088).

ODT reader:

• Fix start numbers with text:continue-numbering (#9595).

Markdown writer:

• Write wide tables as grid tables instead of falling back to HTML (#11945, Aslak Hellesøy).
• Don’t drop notes in notes.
• Fix regression with code block language (#11987). We try to identify which class is a language name and emit that as the gfm style info string. If none of the classes match a recognized language, before 3.10.1 we emitted the first class; fater 3.10.1, we emit nothing. This commit reverts to the pre-3.10.1 behavior.

RST writer:

• Don’t drop notes in notes.

Haddock writer:

• Don’t drop notes in notes.

Docx writer:

• Fix multi-paragraph list items (#9197). Previously the docx writer gave the second and subsequent paragraphs of a list item numbering from a separate list with an invisible bullet. This looked right, but semantically these paragraphs were items of another list, which is what Word, screen readers, and pandoc’s own docx reader saw; the list was also split in three. The writer now gives these paragraphs no numbering, just an indentation that lines them up with the text of the list item (as Word’s “List Continue” styles do).

LaTeX writer:

• Use braces around term containing = (#11954). This is needed for the new LaTeX list code, which is triggered by using pdfstandard.

PowerPoint writer:

• Add clrMapOvr to notes slides (#11935, Gaurav Vijay Jadhav). This makes them importable by Keynote.
• Include lang in core document properties.

DocBook, JATS, TEI writers:

• Apply writerIdentifierPrefix prefix consistently.

Typst writer:

• Escape ... and -? ligatures (#11979).
• Use getLang to determine lang and region. Previously only the lang metadata field was consulted, so lang could not be set properly using a variable.

Text.Pandoc.Translations:

• readTranslations now takes the path of the file, for error messages [API change].

Text.Pandoc.Writers.Shared:

• Add wrapColumns, renderWithTemplate [API change]. These factor out code that was repeated in about 20 writers: computing the line length from writerWrapText/writerColumns, and rendering the body with or without the template.

Text.Pandoc.Shared:

• Export plainToPara and paraToPlain. [API change]

Text.Pandoc.PDF:

• Make --presentational-hints default for weasyprint. This is necessary to get list attributes (start, ordered list type, etc.) working properly (#11976).

cabal.project:

• Use bundle C option for zlib by default. This allows pandoc to be built without first installing the C library zlib. Those who want to use the system zlib can still compile pandoc that way by overriding this setting in cabal.project.local, or just installing directly from Hackage.
• Default to +http on GHC >= 9.14 (previously done only in CI), so local builds behave the same; -f-http still overrides it.
• Pass wasm link flags for pandoc-cli as ghc-options. cabal only passes ld-options along when it finds an ld program on the PATH. In an environment without one (e.g. nix shell with just the ghc-wasm-meta toolchain), the flags were silently dropped and linking pandoc.wasm failed with undefined setjmp and clock symbols. Use -optl- ghc-options instead, which GHC passes to its linker regardless.

Makefile:

• Add release target.
• Improve make pandoc-templates so it does the whole job.
• Use bash as SHELL (check-cabal uses pushd, check-version-sync uses ==).
• Fix $(id -u) in debpkg, which make expanded to empty.
• Fix missing echo in validate-docx-golden-tests{,2}.
• Ensure pandoc is built before rules that run it to produce files.
• Use git ls-files for SOURCEFILES, not the main branch’s tree.
• Drop redundant embed_data_files flag in quick-stack.

Use released citeproc 0.14.1.1, texmath 0.13.3.3, gridtables 0.1.1.1 (#9085).

MANUAL.txt:

• Clarify the effect of raw_html in commonmark formats (#8305).

Bump bounds on crypton, crypton-x509-system, tasty-bench.

Add tools/circleci-build-release.sh, tools/github-build-release.sh.
