* LaTeX writer: Fixed position of label in figures (2813).
Previously the label wasn't in the right place, and `\ref`
wouldn't work properly.
* Added .tei test files to pandoc.cabal so they'll be included
in tarball (2811).
* Updated copyright dates.

* Fixed serious regression in `htmlInBalanced`, which caused
newlines to be omitted in some raw HTML blocks in Markdown
(2804).

* File scope is no longer used when there are no input files (i.e.,
when input comes from stdin). Previously file scope was triggered
when the `json` reader was specified and input came from `stdin`,
and this caused no output to be produced. (Fix due to Jesse Rosenthal;
thanks to Fedor Sheremetyev for calling the bug to our attention.)
* Improved documentation of templates (2797).

* 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-kate83).

* 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.

* Depend on deepseq rather than deepseq-generics (fpco/stackage1096).

* Fixed regression in latex smart quote parsing (2645).
In cases where a match was not found for a quote, everything
from the open quote to the end of the paragraph was being dropped.

* Fixed regression with `--latex-engine` (2618). In 1.16 `--latex-engine`
raises an error if a full path is given.

* Org reader: Fix function dropping subtrees tagged `:noexport`
(Albert Krewinkel, 2628):

* Markdown reader: renormalize table column widths if they exceed 100%
(2626).

* Textile reader: don't allow block HTML tags in inline contexts.
The reader previously did allow this, following redcloth,
which happily parses

Html blocks can be <div>inlined</div> as well.

as

<p>Html blocks can be <div>inlined</div> as well.</p>

This is invalid HTML. The above sample now produces;

<p>Html blocks can be</p>
<div>
<p>inlined</p>
</div>
<p>as well.</p>

* Improved default template lookup for custom lua scripts (2625).
Previously, if you tried to do `pandoc -s -t /path/to/lua/script.lua`,
pandoc would look for the template in
`~/.pandoc/templates/default./path/to/lua/script.lua`.
With this change it will look in the more reasonable
`~/.pandoc/templates/default.script.lua`. This makes it possible to
store default templates for custom writers.

* RST, Markdown writers: Fixed rendering of grid tables with blank rows
(2615).

* LaTeX writer: restore old treatment of Span (2624). A Span is
now rendered with surrounding `{}`, as it was before 1.16.

* Entity handling fixes: improved handling of entities like
`&lang;` that require a trailing semicolon. Allow uppercase
`x` in numerical hexidecimal character references, working
around a tagsoup bug.

* `stack.yaml` - use lts-4.0, but with older aeson to avoid excessive
memory use on compile. With aeson 0.10 we were getting an out of
memory error on a 2GB Ubuntu 64-bit VM.

* Improved deb package creation script. Made `DPKGVER` work.
Renamed `COMMIT` to `TREE`. You should now be able to do
`TREE=1.16.0.1 DPKGVER=2 make deb`.
