ANN: pandoc 2.11.4

[John MacFarlane]

I'm pleased to announce the release of pandoc 2.11.4,
available in the usual places:

Binary packages & changelog:
https://github.com/jgm/pandoc/releases/tag/2.11.4

Source & API documentation:
http://hackage.haskell.org/package/pandoc-2.11.4

As usual, there are a number of bug fixes and small improvements.
The main user-facing changes are:

- biblatex and bibtex now work as output formats as well as
input formats.

- Defaults files can inherit defaults from other defaults files
(using the 'defaults:' field). This allows defaults to be made
modular. (Thanks to David Martschenko.)

- JATS citation output now works again. mixed-citation is used
by default; citations are formatted using the specified CSL style.
When the (new) element_citations extension is enabled,
element-citation is used instead.

- The LaTeX reader now puts contents of unknown environments in a Div
with a class name derived from the environment name, when raw_tex
is not enabled. This allows filters to do something with the environment.

API changes:

- New Text.Pandoc.Writers.BibTeX module, exporting writeBibTeX
and writeBibLaTeX.

- New Ext_element_citations constructor for Extension.

- Text.Pandoc.Citeproc exports getStyle and getReferences.

Thanks to all who contributed and especially to new
contributors David Martschenko and Dimitri Sabadie.
