Use HsYAML instead of yaml for translations and YAML metadata (#4747). yaml wraps a C library; HsYAML is pure Haskell. Advances #4535.

Note: HsYAML implements YAML 1.2, in which the valid true values are true, True, TRUE. This means a change in the semantics of YAML metadata that could affect users: y, yes, and on no longer count as true values.

Fix regression: make --pdf-engine work with full paths (#4681, Mauro Bieg).

CommonMark reader: Handle ascii_identifiers extension (#4742, Anders Waldenborg). Non-ascii characters were not stripped from identifiers even if the ascii_identifiers extension was enabled (which is is by default for gfm).

TikiWiki reader: Improve list parsing (#4722, Mauro Bieg). Remove trailing Space from list items. Parse lists that have no space after marker.

LaTeX reader:

• Treat lilypond as a verbatim environment (#4725).
• Parse figure label into Image id (#4700, Mauro Bieg).
• Beamer: Allow “noframenumbering” option (#4696, Raymond Ehlers).
• Allow spaces around \graphicspath arguments (#4698).
• Handle includes without surrounding blanklines (#4553). In addition, \input can now be used in an inline context, e.g. to provide part of a paragraph, as it can in LaTeX.
• In rawLaTeXBlock, handle macros that resolve to a \begin or \end (#4667).
• In rawLaTeXBlock, don’t expand macros in macro definitions (#4653). Note that this only affected LaTeX in markdown.
• Tighten up reading of beamer overlay specifications (#4669). Ideally we’d turn these on only when reading beamer, but currently beamer is not distinguished from latex as an input format. This commit also activates parsing of overlay specifications after commands in general (e.g. \item), since they can occur in many contexts in beamer.
• Parse more siunitx unit commands (#4296, #4773).
• Be more forgiving in key/value option parsing (#4761).

Markdown reader:

• Allow empty code spans, e.g. ` `.
• Emojis are now wrapped in Spans with class emoji and attribute data-emoji (Anders Waldenborg, #4743). This allows the writer to handle them in a special way (e.g. using a special font, or just rendering the emoji name).

Muse reader (Alexander Krotov, except where indicated):

• Get rid of non-exhaustive pattern match warning (Mauro Bieg).
• Add support for floating images.
• Add support for images with specified width.
• Parse image URLs without “guard” and “takeExtension”.
• Split link and image parsing into separate functions.
• Parse links starting with “URL:” explicitly instead of trying to strip “URL:” prefix after parsing.

Texinfo writer: Use @sup and @sub instead of custom macros (#4728, Alexander Krotov).

Markdown writer: Preserve implicit_figures with attributes, even if implicit_attributes is not set, by rendering in raw HTML (#4677).

Markdown and commonmark/github writers now respect the emoji extension. So, -f markdown+emoji -t markdown+emoji now leaves :smile: as :smile: rather than converting it to a smile character.

Docx writer: Be sensitive to toc in YAML metadata (#4645).

ODT/OpenDocument writer: Make internal links work (#4358). This adds proper bookmarks to the headers with non-null IDs.

EPUB writer: Properly escape pagetitle. Previously we weren’t escaping & and other XML characters in the pagetitle, so a title containing a & would be invalid.

AsciiDoc Writer: Eescape square brackets at start of line (#4545, Mauro Bieg).

RST writer:

• Don’t treat ‘example’ as a syntax name (#4748). This fixes conversions from org with example blocks.
• Support --number-sections via the section-numbering directive in standalone output.

reveal.js writer and template: reuse mathjax URL provided by the argument to --mathjax or the normal pandoc default, rather than a hard-coded one in the template (#4701).

LaTeX writer:

• Properly handle footnotes in table captions (#4683). Refactored code from figure captions to use in both places.
• In beamer output, fix single digit column percentage (#4690, Mauro Bieg).

FB2 writer (Alexander Krotov):

• Convert Plain to Para in annotation (#2424).
• Fix order of items in title-info (#2424).

Custom writer: fix error message on script failure (Albert Krewinkel). Error messages produced by Lua were not displayed by Pandoc.

Text.Pandoc.Emoji now exports emojiToInline, which returns a Span inline containing the emoji character and some attributes with metadata (class emoji, attribute data-emoji with emoji name). (API change, Anders Waldenborg, #4743).

Text.Pandoc.PDF:

• Revert fix for #4484 (only compress images on last run, #4755). This will mean some increase in the time it takes to produce an image-heavy PDF with xelatex, but it will make tables of contents correct, which is more important.
• Fix logic error in runTeXProgram. We were running the tex program one more time than requested. This should speed up PDF production.

Allow --template to take a URL as argument.

Text.Pandoc.Highlighting: Add missing re-export of breezeDark highlighting style (#4687, Adrian Sieber, API change).

Clarify macOS install in INSTALL.md (#4661). Make the binary package installer the recommended method, and note that on some older versions of macOS, homebrew installs from source and takes a lot of disk space (#4664, Ian).

MANUAL:

• Clarify EPUB linked media (#4756, Mauro Bieg)
• Update manual for “true” YAML values. Now that we’re using HsYAML and YAML 1.2, the valid true values are true, True, TRUE. NOTE! y, yes, on no longer count as true values.
• Document -F as alias for --filter (thanks to Gandalf Saxe).
• Update manual on how math is rendered in LaTeX.
• Add proxy description (#4131, Mauro Bieg).
• Clarify that --toc requires --standalone (#4703).
• Update citation styles link (#4699, wiefling).

In API docs, clarify how Ext_east_asian_line_breaks extension works (kaizshang91). Note that it will not take effect when readers/writers are called as libraries (#4674).

Improved translations/fr (#4766, lux-lth).

Removed inadvertently added .orig files from repository (#4648).

Remove network-uri flag and use ‘Network.Socket’. This removes a compiler warning. There is no need for the old network-uri flag, since network 2.6 was released in 2014.

Add stack.lts10.yaml, stack.lts11.yaml. use lts-12 in stack.yaml.

Bump upper bounds for dependent packages.

Exclude foundation 0.0.21 for ghc 7.10. Otherwise cabal gets confused because of the way ghc 7.10 is excluded in foundation’s cabal file. This can be removed when haskell-foundation/foundation#500 is fixed.

Require cabal-version >= 2.0. This is needed for haddock-library.
