Added --file-scope option (Jesse Rosenthal). By default pandoc operates on multiple files by first concatenating them (around extra line breaks) and then processing the joined file. So it only parses a multi-file document at the document scope. This has the benefit that footnotes and links can be in different files, but for some purposes it is useful to parse the individual files first and then combine their outputs (e.g. when the files use footnotes or links with the same labels). The --file-scope option causes pandoc to parse the files first, and then combine the parsed output, instead of combining before parsing. --file-scope is selected automatically for binary input files (which cannot be concatenated) and for pandoc json.

Add TEI Writer (Chris Forster) and tei output format.

Added a general ByteStringReader with warnings, used by the docx reader (API change, Jesse Rosenthal).

Add readDocxWithWarnings (API change, Jesse Rosenthal).

Changed type of Shared.uniqueIdent's argument from [String] to Set String. This avoids performance problems in documents with many identically named headers (API change, #2671).

Removed tex_math_single_backslash from markdown_github options (#2707).

Make language extensions as well as full language names trigger syntax highlighting. For example, py will now work as well as python (jgm/highlighting-kate#83).

Added institute variable to latex, beamer templates (Fraser Tweedale, Josef Svenningsson).

Docx reader (Jesse Rosenthal):

• Handle alternate content. Some word functions (especially graphics) give various choices for content so there can be backwards compatibility.
• Don't turn numbered headers into lists.
• Docx Reader: Add state to the parser, for warnings
• Update feature checklist in source code.
• Get rid of Modifiable typeclass.
• Add tests for adjacent hyperlinks.
• Add a "Link" modifier to Reducible. We want to make sure that links have their spaces removed, and are appropriately smushed together (#2689).

HTML reader:

• Fixed behavior of base tag (#2777). If the base path does not end with slash, the last component will be replaced. E.g. base = http://example.com/foo combines with bar.html to give http://example.com/bar.html. If the href begins with a slash, the whole path of the base is replaced. E.g. base = http://example.com/foo/ combines with /bar.html to give http://example.com/bar.html.
• Rewrote htmlInBalanced. This version avoids an exponential performance problem with <script> tags, and it should be faster in general (#2730).
• Properly handle an empty cell in a simple table (#2718).
• Handle multiple <meta> tags with same name. Put them in a list in the metadata so they are all preserved, rather than (as before) throwing out all but one..

Markdown reader:

• Improved pipe table parsing (#2765).
• Allow + separators in pipe table cells. We already allowed them in the header, but not in the body rows, for some reason. This gives compatibility with org-mode tables.
• Don't cross line boundary parsing pipe table row. Previously an Emph element could be parsed across the newline at the end of the pipe table row.
• Use htmlInBalanced for rawVerbatimBlock, for better performance (#2730).
• Fixed bug with smart quotes around tex math.

LaTeX reader:

• Handle interior $ characters in math (#2743). For example, $$\hbox{$i$}$$.
• inlineCommand now gobbles an empty {} after any command (#2687). This gives better results when people write e.g. \TeX{} in Markdown.
• Properly handle LaTeX "math" environment as inline math (#2171).

Textile reader: Support >, <, =, <> text alignment attributes. Closes #2674.

Org reader (Albert Krewinkel):

• Prefix even empty figure names with "fig:" (#2643). The convention used by pandoc for figures is to mark them by prefixing the name with fig:. The org reader failed to do this if a figure had no name.
• Refactor link-target processing (#2684).

ConTeXt writer: Fix whitespace at line beginning in line blocks (#2744). Thanks to @c-foster.

HTML writer: Don't include alignment attribute for default table columns. Previously these were given "left" alignment. Better to leave off alignment attributes altogether (#2694).

Markdown writer: Use hyphens for YAML metadata block bottom line, for better compatibility with other Markdown flavors (Henrik Tramberend).

LaTeX writer:

• Use image identifier to create a label and hypertarget for figures (Mauro Bieg).
• Avoid double toprule in headerless table with caption (#2742).
• Clean up options parser (Jesse Rosenthal).
• Treat memoir template with article option as article, instead of treating all memoir templates as books.
• Allow more flexible table alignment (Henrik Tramberend, #2665). New default is not to include [c] option (which is the default anyway if no positioning is specified). Now LaTeX emplates can control the overall table alignment in a document by setting the longtable length variables LTleft and LTright. For example, \setlength\LTleft\parindent\setlength\LTright\fill will create left-aligned tables that respect paragraph indentation.

Docx writer: Handle image alt text (#2754, Mauro Bieg).

Org writer - pass through RawInline with format "org".

DokuWiki writer: use $$ for display math.

Custom writer: Pass attributes parameter to CaptionedImage (#2697).

Make protocol-relative URIs work again (#2737).

make_osx_package.sh: Use env variable for developer id certs.

Raise tagsoup lower bound to 0.13.7 to fix entity-related problems (#2734).

Allow zip-archive 0.3.

Allow aeson 0.11.
