• Made it possible to run filters that aren't executable (#1096).
  Pandoc first tries to find the executable (searching the path
  if path isn't given). If it fails, but the file exists and has
  a .py, .pl, .rb, .hs, or .php extension, pandoc runs the filter
  using the appropriate interpreter. This should make it easier to
  use filters on Windows, and make it more convenient for everyone.
• Added Emacs org-mode reader (Albert Krewinkel).
• Added InDesign ICML Writer (mb21).
• MediaWiki reader:
  • Accept image links in more languages (Jaime Marquínez Ferrándiz).
  • Fixed bug in certain nested lists (#1213). If a level 2 list was
    followed by a level 1 list, the first item of the level 1 list
    would be lost.
  • Handle table rows containing just an HTML comment (#1230).
• LaTeX reader:
  • Give better location information on errors, pointing to line
    numbers within included files (#1274).
  • LaTeX reader: Better handling of table environment (#1204).
    Positioning options no longer rendered verbatim.
  • Better handling of figure and table with caption (#1204).
  • Handle @{} and p{length} in tabular. The length is not actually
    recorded, but at least we get a table (#1180).
  • Properly handle \nocite. It now adds a nocite metadata
    field. Citations there will appear in the bibliography but not
    in the text (unless you explicitly put a $nocite$ variable
    in your template).
• Markdown reader:
  • Ensure that whole numbers in YAML metadata are rendered without
    decimal points. (This became necessary with changes to aeson
    and yaml libraries. aeson >= 0.7 and yaml >= 0.8.8.2 are now required.)
  • Fixed regression on line breaks in strict mode (#1203).
  • Small efficiency improvements.
  • Improved parsing of nested divs. Formerly a closing div tag
    would be missed if it came right after other block-level tags.
  • Avoid backtracking when closing </div> not found.
  • Fixed bug in reference link parsing in markdown_mmd.
  • Fixed a bug in list parsing (#1154). When reading a raw list
    item, we now strip off up to 4 spaces.
  • Fixed parsing of empty reference link definitions (#1186).
  • Made one-column pipe tables work (#1218).
• Textile reader:
  • Better support for attributes. Instead of being ignored, attributes
    are now parsed and included in Span inlines. The output will be a bit
    different from stock textile: e.g. for *(foo)hi*, we'll get
    <em><span class="foo">hi</span></em> instead of
    <em class="foo">hi</em>. But at least the data is not lost.
  • Improved treatment of HTML spans (%) (#1115).
  • Improved link parsing. In particular we now pick up on attributes.
    Since pandoc links can't have attributes, we enclose the whole link in
    a span if there are attributes (#1008).
  • Implemented correct parsing rules for inline markup (#1175, Matthew
    Pickering).
  • Use Builder (Matthew Pickering).
• DocBook reader:
  • Better treatment of formalpara. We now emit the title (if present)
    as a separate paragraph with boldface text (#1215).
  • Set metadata author not authors.
  • Added recognition of authorgroup and releaseinfo elements (#1214,
    Matthew Pickering).
  • Converted current meta information parsing in DocBook to a more
    extensible version which is aware of the more recent meta
    representation (Matthew Pickering).
• HTML reader:
  • Require tagsoup 0.13.1, to fix a bug with parsing of script tags
    (#1248).
  • Treat processing instructions & declarations as block. Previously
    these were treated as inline, and included in paragraph tags in HTML
    or DocBook output, which is generally not what is wanted (#1233).
  • Updated closes with rules from HTML5 spec.
  • Use Builder (Matthew Pickering, #1162).
• RST reader:
  • Remove duplicate http in PEP links (Albert Krewinkel).
  • Make rst figures true figures (#1168, CasperVector)
  • Enhanced Pandoc's support for rST roles (Merijn Verstaaten).
    rST parser now supports: all built-in rST roles, new role definition,
    role inheritance, though with some limitations.
  • Use author rather than authors in metadata.
  • Better handling of directives. We now correctly handle field
    lists that are indented more than three spaces. We treat an
    aafig directive as a code block with attributes, so it can be
    processed in a filter (#1212).
• LaTeX writer:
  • Mark span contents with label if span has an ID (Albert Krewinkel).
  • Made --toc-depth work well with books in latex/pdf output (#1210).
  • Handle line breaks in simple table cells (#1217).
  • Workaround for level 4-5 headers in quotes. These previously produced
    invalid LaTeX: \paragraph or \subparagraph in a quote environment.
    This adds an mbox{} in these contexts to work around the problem.
    See http://tex.stackexchange.com/a/169833/22451 (#1221).
  • Use \/ to avoid en-dash ligature instead of -{}- (Vaclav Zeman).
    This is to fix LuaLaTeX output. The -{}- sequence does not avoid the
    ligature with LuaLaTeX but \/ does.
  • Fixed string escaping in hyperref and hyperdef (#1130).
• ConTeXt writer: Improved autolinks (#1270).
• DocBook writer:
  • Improve handling of hard line breaks in Docbook writer
    (Neil Mayhew). Use a <literallayout> for the entire paragraph, not
    just for the newline character.
  • Don't let line breaks inside footnotes influence the enclosing
    paragraph (Neil Mayhew).
  • Distinguish tight and loose lists in DocBook output, using
    spacing="compact" (Neil Mayhew, #1250).
• Docx writer: When needed files are not present in the user's
  reference.docx, fall back on the versions in the reference.docx
  in pandoc's data files. This fixes a bug that occurs when a
  reference.docx saved by LibreOffice is used. (#1185)
• EPUB writer:
  • Include extension in epub ids. This fixes a problem with duplicate
    extensions for fonts and images with the same base name but different
    extensions (#1254).
  • Handle files linked in raw img tags (#1170).
  • Handle media in audio source tags (#1170).
    Note that we now use a media directory rather than images.
  • Incorporate files linked in video tags (#1170). src and poster
    will both be incorporated into content.opf and the epub container.
• HTML writer:
  • Add colgroup around col tags (#877). Also affects EPUB writer.
  • Fixed bug with unnumbered section headings. Unnumbered section
    headings (with class unnumbered) were getting numbers.
  • Improved detection of image links. Previously image links with
    queries were not recognized, causing <embed> to be used instead
    of <img>.
• Man writer: Ensure that terms in definition lists aren't line wrapped
  (#1195).
• Markdown writer:
  • Use proper escapes to avoid unwanted lists (#980). Previously we used
    0-width spaces, an ugly hack.
  • Use longer backtick fences if needed (#1206). If the content contains a
    backtick fence and there are attributes, make sure longer fences are
    used to delimit the code. Note: This works well in pandoc, but github
    markdown is more limited, and will interpret the first string of three
    or more backticks as ending the code block.
• RST writer: Avoid stack overflow with certain tables (#1197).
• RTF writer: Fixed table cells containing paragraphs.
• Custom writer:
  • Correctly handle UTF-8 in custom lua scripts (#1189).
  • Fix bugs with lua scripts with mixed-case filenames and
    paths containing + or - (#1267). Note that getWriter
    in Text.Pandoc no longer returns a custom writer on input
    foo.lua.
• AsciiDoc writer: Handle multiblock and empty table cells
  (#1245, #1246). Added tests.
• Text.Pandoc.Options: Added readerTrace to ReaderOptions
• Text.Pandoc.Shared:
  • Added compactify'DL (formerly in markdown reader) (Albert Krewinkel).
  • Fixed bug in toRomanNumeral: numbers ending with '9' would
    be rendered as Roman numerals ending with 'IXIV' (#1249). Thanks to
    Jesse Rosenthal.
  • openURL: set proxy with value of http_proxy env variable (#1211).
    Note: proxies with non-root paths are not supported, due to
    limitations in http-conduit.
• Text.Pandoc.PDF:
  • Ensure that temp directories deleted on Windows (#1192). The PDF is
    now read as a strict bytestring, ensuring that process ownership will
    be terminated, so the temp directory can be deleted.
  • Use / as path separators in a few places, even on Windows.
    This seems to be necessary for texlive (#1151, thanks to Tim Lin).
  • Use ; for TEXINPUTS separator on Windows (#1151).
  • Changes to error reporting, to handle non-UTF8 error output.
• Text.Pandoc.Templates:
  • Removed unneeded datatype context (Merijn Verstraaten).
  • YAML objects resolve to "true" in conditionals (#1133).
    Note: If address is a YAML object and you just have $address$
    in your template, the word true will appear, which may be
    unexpected. (Previously nothing would appear.)
• Text.Pandoc.SelfContained: Handle poster attribute in video
  tags (#1188).
• Text.Pandoc.Parsing:
  • Made F an instance of Applicative (#1138).
  • Added stateCaption.
  • Added HasMacros, simplified other typeclasses.
    Removed updateHeaderMap, setHeaderMap, getHeaderMap,
    updateIdentifierList, setIdentifierList, getIdentifierList.
  • Changed the smart punctuation parser to return Inlines
    rather than Inline (Matthew Pickering).
  • Changed HasReaderOptions, HasHeaderMap, HasIdentifierList
    from typeclasses of monads to typeclasses of states. This simplifies
    the instance definitions and provides more flexibility. Generalized
    type of getOption and added a default definition. Removed
    askReaderOption. Added extractReaderOption. Added
    extractHeaderMap and updateHeaderMap in HasHeaderMap.
    Gave default definitions for getHeaderMap, putHeaderMap,
    modifyHeaderMap. Added extractIdentifierList and
    updateIdentifierList in HasIdentifierList. Gave defaults
    for getIdentifierList, putIdentifierList, and
    modifyIdentifierList. The ultimate goal here is to allow different
    parsers to use their own, tailored parser states (instead of
    ParserState) while still using shared functions.
• Template changes:
  • LaTeX template: Use fontenc package only with pdflatex (#1164).
  • LaTeX template: Add linestretch and fontfamily variables.
  • LaTeX template: Conditionalize author and date commands.
  • Beamer template: Consistent styles for figure and table captions
    (aaronwolen).
  • LaTeX and beamer template: Adjust widths correctly for oversized
    images. Use \setkeys{Gin}{} to set appropriate defaults for
    \includegraphics (Yihui Xie, Garrick Aden-Buie). Load
    upquote only after fontenc (Yihui Xie).
  • Beamer template: Added caption package (#1200).
  • Beamer template: changes for better unicode handling (KarolS).
  • DocBook template: use authorgroup if there are authors.
  • revealjs template: Move include-after to end (certainlyakey).
  • revealjs template: Fixed PDF print function (#1220, kevinkenan).
• Bumped version bounds of dependencies.
• Added a --trace command line option, for debugging backtracking
  bugs. So far this only works with the markdown reader.
• MathMLinHTML: Fixed deprecation warning (#362, gwern, Albert Krewinkel).
• Updated travis script to test with multiple GHC versions.
• Force failure of a Travis build if GHC produces warnings (Albert
  Krewinkel).
• Add .editorconfig (Albert Krewinkel).
  See http://editorconfig.org/ for details.
• Give more useful error message if '-t pdf' is specified (#1155).
• Added Cite, SmallCaps to Arbitrary instance (#1269).
• Allow html4 as a synonym of html as a reader (it already works
  as a writer).
• README:
  • Added an explanation of how to use YAML metadata to
    force items to appear in the bibliography without citations in
    the text (like LaTeX \nocite).
  • Added note to --bibtex/--natbib: not for use in making PDF
    (#1194, thanks to nahoj).
  • Added explanatory notes about --natbib and --biblatex.
  • Added specification of legal syntax for citation keys.
  • Fixed variable defaults documentation (Albert Krewinkel).
• Removed copyright statements for files that have been removed
  (Albert Krewinkel).
• Moved some doc files from data-files to extra-source-files (#1123).
  They aren't needed at runtime. We keep README and COPYRIGHT in data
  to ensure that they'll be available on all systems on which pandoc
  is installed.
• Use cabal sandboxes in Windows build script.
