Lua filters: preload text module (Albert Krewinkel, #4077).
The text module is preloaded in lua. The module contains some UTF-8
aware string functions, implemented in Haskell. The module is loaded on
request only, e.g.:

text = require 'text'
function Str (s)
  s.text = text.upper(s.text)
  return s
end

Allow table-like access to attributes in lua filters (Albert Krewinkel,
#4071). Attribute lists are represented as associative lists in Lua. Pure
associative lists are awkward to work with. A metatable is attached to
attribute lists, allowing to access and use the associative list as if
the attributes were stored in as normal key-value pair in table.
Note that this changes the way pairs works on attribute lists. Instead
of producing integer keys and two-element tables, the resulting iterator
function now returns the key and value of those pairs. Use ipairs to
get the old behavior. Warning: the new iteration mechanism only works if
pandoc has been compiled with Lua 5.2 or later (current default: 5.3).

Text.Pandoc.Parsing.uri: allow & and = as word characters (#4068).
This fixes a bug where pandoc would stop parsing a URI with an
empty attribute: for example, &a=&b= wolud stop at a.
(The uri parser tries to guess which punctuation characters
are part of the URI and which might be punctuation after it.)

Introduce HasSyntaxExtensions typeclass (Alexander Krotov, #4074).

• Added new HasSyntaxExtensions typeclass for ReaderOptions and
  WriterOptions.
• Reimplemented isEnabled function from Options.hs to accept both
  ReaderOptions and WriterOptions.
• Replaced enabled from CommonMark.hs with new isEnabled.

Add amuse extension (Alexander Krotov) to enable Amuse wiki
behavior for muse. New Ext_amuse constructor for
Extension. Note: this is switched on by default; for
Emacs behavior, use muse-amuse.

Muse reader (Alexander Krotov):

• Count only one space as part of list item marker.
• Produce SoftBreaks on newlines. Now wrapping can be preserved
  with --wrap=preserve.
• Add Text::Amuse footnote extensions. Footnote end is indicated by
  indentation, so footnotes can be placed anywhere in the text,
  not just at the end of it.
• Accept Emacs Muse definition lists when -amuse.
  Emacs Muse does not require indentation.

HTML reader:

• Ensure we don’t produce level 0 headers (#4076), even for chapter
  sections in epubs. This causes problems because writers aren’t set
  up to expect these.
• Allow spaces after \( and before \) with tex_math_single_backslash.
  Previously \( \frac{1}{a} < \frac{1}{b} \) was not parsed as math in
  markdown or html +tex_math_single_backslash.

MANUAL: clarify that math extensions work with HTML.
Clarify that tex_math_dollars and tex_math_single_backslash
will work with HTML as well as Markdown.

Creole reader: Fix performance issue for longer lists (Sascha Wilde,
#4067).

RST reader: better support for ‘container’ directive (#4066).
Create a div, incorporate name attribute and classes.

LaTeX reader:

• Support column specs like *{2}{r} (#4056). This is equivalent to
  rr. We now expand it like a macro.
• Allow optional args for parbox (#4056).
• Allow optional arguments on \footnote (#4062).

EPUB writer: Fixed path for cover image (#4069). It was previously
media/media/imagename, and should have been media/imagename.

Markdown writer: fix bug with doubled footnotes in grid tables
(#4061).

LaTeX template: include natbib/biblatex after polyglossia (#4073).
Otherwise we seem to get an error; biblatex wants polyglossia
language to be defined.

Added examples to lua filters documentation.
