Features added
--------------
Bugs fixed
----------
* LaTeX: some system labels are not translated
* RemovedInSphinx30Warning is marked as pending
* deprecation warnings are not emitted
- sphinx.application.CONFIG_FILENAME
- sphinx.builders.htmlhelp
- :confval:`viewcode_import`
* #6208: C++, properly parse full xrefs that happen to have a short xref as prefix.
* #6220, #6225: napoleon: AttributeError is raised for raised section having
references
* #6245: circular import error on importing SerializingHTMLBuilder
* #6243: LaTeX: 'releasename' setting for latex_elements is ignored
Testing
--------
Release 2.0.0 (released Mar 29, 2019)
=====================================
Dependencies
------------
2.0.0b1
* LaTeX builder now depends on TeX Live 2015 or above.
* LaTeX builder (with ``'pdflatex'`` :confval:`latex_engine`) will process
Unicode Greek letters in text (not in math mark-up) via the text font and
will not escape them to math mark-up. See the discussion of the
``'fontenc'`` key of :confval:`latex_elements`; such (optional) support for
Greek adds, for example on Ubuntu xenial, the ``texlive-lang-greek`` and (if
default font set-up is not modified) ``cm-super(-minimal)`` as additional
Sphinx LaTeX requirements.
* LaTeX builder with :confval:`latex_engine` set to ``'xelatex'`` or to
``'lualatex'`` requires (by default) the ``FreeFont`` fonts,
which in Ubuntu xenial are provided by package ``fonts-freefont-otf``, and
e.g. in Fedora 29 via package ``texlive-gnu-freefont``.
* requests 2.5.0 or above
* The six package is no longer a dependency
* The sphinxcontrib-websupport package is no longer a dependency
* Some packages are separated to sub packages:
- sphinxcontrib.applehelp
- sphinxcontrib.devhelp
- sphinxcontrib.htmlhelp
- sphinxcontrib.jsmath
- sphinxcontrib.serializinghtml
- sphinxcontrib.qthelp
Incompatible changes
--------------------
2.0.0b1
* Drop python 2.7 and 3.4 support
* Drop docutils 0.11 support
* Drop features and APIs deprecated in 1.7.x
* The default setting for :confval:`master_doc` is changed to ``'index'`` which
has been longly used as default of sphinx-quickstart.
* LaTeX: Move message resources to ``sphinxmessage.sty``
* LaTeX: Stop using ``\captions<lang>`` macro for some labels
* LaTeX: for ``'xelatex'`` and ``'lualatex'``, use the ``FreeFont`` OpenType
fonts as default choice (refs: #5645)
* LaTeX: ``'xelatex'`` and ``'lualatex'`` now use ``\small`` in code-blocks
(due to ``FreeMono`` character width) like ``'pdflatex'`` already did (due
to ``Courier`` character width). You may need to adjust this via
:confval:`latex_elements` ``'fvset'`` key, in case of usage of some other
OpenType fonts (refs: #5768)
* LaTeX: Greek letters in text are not escaped to math mode mark-up, and they
will use the text font not the math font. The ``LGR`` font encoding must be
added to the ``'fontenc'`` key of :confval:`latex_elements` for this to work
(only if it is needed by the document, of course).
* LaTeX: setting the :confval:`language` to ``'en'`` triggered ``Sonny`` option
of ``fncychap``, now it is ``Bjarne`` to match case of no language specified.
(refs: #5772)
* #5770: doctest: Follow :confval:`highlight_language` on highlighting doctest
block. As a result, they are highlighted as python3 by default.
* The order of argument for ``HTMLTranslator``, ``HTML5Translator`` and
``ManualPageTranslator`` are changed
* LaTeX: hard-coded redefinitions of ``\l@section`` and ``\l@subsection``
formerly done during loading of ``'manual'`` docclass get executed later, at
time of ``\sphinxtableofcontents``. This means that custom user definitions
from LaTeX preamble now get overwritten. Use ``\sphinxtableofcontentshook``
to insert custom user definitions. See :ref:`latex-macros`.
* quickstart: Simplify generated ``conf.py``
* #4148: quickstart: some questions are removed. They are still able to specify
via command line options
* websupport: unbundled from sphinx core. Please use sphinxcontrib-websupport
* C++, the visibility of base classes is now always rendered as present in the
input. That is, ``private`` is now shown, where it was ellided before.
* LaTeX: graphics inclusion of oversized images rescales to not exceed
the text width and height, even if width and/or height option were used.
(refs: #5956)
* epub: ``epub_title`` defaults to the :confval:`project` option
* #4550: All tables and figures without ``align`` option are displayed to center
* #4587: html: Output HTML5 by default
2.0.0b2
* texinfo: image files are copied into ``name-figure`` directory
Deprecated
----------

configuration files which should be converted to Python 3.

Features added
--------------
2.0.0b1
* #1618: The search results preview of generated HTML documentation is
reader-friendlier: instead of showing the snippets as raw reStructuredText
markup, Sphinx now renders the corresponding HTML. This means the Sphinx
extension `Sphinx: pretty search results`__ is no longer necessary. Note that
changes to the search function of your custom or 3rd-party HTML template might
overwrite this improvement.
__ https://github.com/sphinx-contrib/sphinx-pretty-searchresults

(``added``, ``changed`` and ``deprecated``, respectively) in addition to the
generic ``versionmodified`` class.

object. Please use ``config.gettext_compact`` instead.

domains, :event:`doctree-read` event and versioning doctrees are invoked
earlier than so far. For more details, please read a description of
:py:meth:`.Sphinx.add_transform()`
* #4827: All ``substitution_definition`` nodes are removed from doctree on

* LaTeX: with lualatex or xelatex use by default :program:`xindy` as

upgrading Sphinx, please clean latex build repertory of existing project
before new build.
* #5163: html: hlist items are now aligned to top
* ``highlightlang`` directive is processed on resolving phase
