Fixes:

- LaTeX implementation doesn't load `paralist` in `beamer` unless requested.

## 2.1.2 (2016-09-14)

Fixes:

- Unordered list items now may begin with a `bulletchar`.

Documentation:

- Expanded the documentation on `hashEnumerators`.

## 2.1.1 (2016-09-06)

Fixes:

- The citations extension should now be fully compliant with the
  [Pandoc spec](http://pandoc.org/MANUAL.html#citations).
- The `citationNbsps` option now also affects newlines, as is expected.
- The default `\markdownOptionCacheDir` explicitly specifies the current
  working directory, so that the cache files are not sought in the TeX
  directory structure.

Documentation:

- Added information about the supported LuaTeX versions.
- Added information about the portable use of the package.

Development:

- All the syntax extensions (fenced code blocks and citations) were merged by
  the [upstream project](http://github.com/jgm/lunamark).

## 2.1.0 (2016-08-29)

New features:

- Added Pandoc-style citations and CommonMark fenced code blocks syntax
  extensions.
- Added the following renderers:
  - `interblockSeparator`,
  - `ulItemEnd`, `olItemEnd`, `dlItemEnd`,
  - `nbsp`, `cite`, `textCite`, and
  - `inputFencedCode`.
- Added the following Lua options:
  - `citations`, `citationNbsps`,
  - `fencedCode`, and `blankBeforeCodeFence`.

Changes in behavior:

- Replaced the `-` character in the default `\markdownOptionCacheDir` with `_`.
- The cache filenames are now different based on the version of the package.
- Code spans may now be empty.

Fixes:

- The conversion from Markdown should now produce consistent behavior no matter
  if the input of the conversion function ends with `\n\n`, `\n`, or nothing.
- LaTeX interface `rendererPrototypes` keys for the `pipe`, `link`, and `image`
  renderers no longer incorrectly set the `\markdownRenderers<Renderer>` macros
  rather than the  `\markdownRenderers<Renderer>Prototype` macros.

## 2.0.2 (2016-08-17)

Fixes:

- Fixed nested `keyval` handling inside `\markdownSetup` et al.

## 2.0.1 (2016-08-15)

Fixes:

- Make the programming more defensive, so that the package works correctly
  under TeXLive 2012.

Development:

- Added the package to a continuous integration service.

## 2.0.0 (2016-08-15)

New features:

- Added raw unescaped URI to the `link` and `image` renderer arguments.
  (This breaks backwards compatibility, hence the major version number bump.)
- Added renderers for plain TeX and ConteXt special characters.

Fixes:

- Make autolinks work by preventing `Str` from consuming `<`.
- Non-found footnote ref no longer outputs unescaped text.
- Catcode of `|` is now other in `\markdownReadAndConvert` for ConTeXt.
- Restore escapability of `<`, `>` to enable escaping of autolinks.

Development:

- Added a suite of tests.
