Sphinx 0.4 released

[Georg Brandl]

I'm pleased to announce the next minor version of Sphinx, the Python
documentation generation tool.

What is it?
===========

Sphinx is a tool that makes it easy to create intelligent and beautiful
documentation for Python projects (or other documents consisting of
multiple reStructuredText source files).

Its website is at <http://sphinx.pocoo.org/>.


Important changes
=================
(full list at http://sphinx.pocoo.org/changes.html)

* The new config value `default_role` can be used to select the
   default role for all documents.

* Sphinx now interprets field lists with fields like ``:param foo:``
   in description units.

* The new `staticmethod` directive can be used to mark methods as
   static methods.

* The new TextBuilder creates plain-text output.

* Autodoc Extension:

   - The autodoc extension now offers a much more flexible way to
     manipulate docstrings before including them into the output, via
     the new `autodoc-process-docstring` event.

   - The `autodoc` extension accepts signatures for functions, methods
     and classes now that override the signature got via introspection
     from Python code.

   - The `autodoc` extension now offers a ``show-inheritance`` option
     for autoclass that inserts a list of bases after the signature.

   - The autodoc directives now support the ``noindex`` flag option.

* HTML output:

   - The "previous" and "next" links have a more logical structure, so
     that by following "next" links you can traverse the entire TOC
     tree.

   - The new event `html-page-context` can be used to include custom
     values into the context used when rendering an HTML template.

   - The new config value `html_favicon` can be used to set a favicon
     for the HTML output.  Thanks to Sebastian Wiesner.

   - The new config value `html_split_index` can be used to create
     separate index pages for each letter, to be used when the complete
     index is too large for one page.

   - The module index now isn't collapsed if the number of submodules
     is larger than the number of toplevel modules.

* The image directive now supports specifying the extension as ``.*``,
   which makes the builder select the one that matches best.  Thanks to
   Sebastian Wiesner.

* The new config value `exclude_trees` can be used to exclude whole
   subtrees from the search for source files.

* Python 3-style signatures, giving a return annotation via ``->``,
   are now supported.


Enjoy!
