+pandoc (1.17)
+
+  * Added `--file-scope` option (Jesse Rosenthal).
+    Traditionally 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 it also
+    introduces some difficulties: (a) it is difficult to join files with
+    footnotes without some sort of preprocessing, which makes it difficult
+    to write academic documents in small pieces; (b) it makes it impossible
+    to process multiple binary input files, which can't be catted; (c) it
+    makes it impossible to process files from different input formats.
+    The `--file-scope` option causes pandoc to parse the files first,
+    and then combine the parsed output, instead of combining before
+    parsing. This makes it impossible to have links across multiple files,
+    and auto-identified headers won't work correctly if headers in multiple
+    files have the same name. On the other hand, footnotes across multiple
+    files will work correctly and will allow more freedom for input formats.
+    `--file-scope` is selected automatically for binary input files (which
+    cannot be concatenated anyway) and for pandoc json.
+
+  * Add TEI Writer (csforste) 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 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).
+
+  * 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:
+
+    + 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.
+
 pandoc (1.16.0.2)
 
   * Depend on deepseq rather than deepseq-generics (fpco/stackage#1096).
