v0.0.1, 2013-03-24 -- Initial release.

v0.1.0, 2013-04-05 -- Working release.
- 'ViewCallable' classes: A collection of classes that can be used as Pyramid
  view-callables.
- 'BaseViewCallable': A non-working base for view-callables.
- 'SimpleViewCallable': Passes the request directly to the wrapped callable.
- 'FunctionViewCallable': Gets keyword arguments by parsing the request. Passes
  those arguments to the wrapped callable, returns the result.
- 'APIViewCallable': Uses 'iomanager' package to coerce/verify input/output.
  View-callable parameters are specified using decorator keyword arguments.
- 'scan_api_tree': A function that scans a dictionary of view-callables and
  registers each of them with a Pyramid 'Configurator' instance. Endpoint paths
  are constructed recursively.

v0.1.0a, 2013-04-08 -- Beta: API documentation
- Add 'api_documentation' module.
- Add 'prepare_item' function to prepare 'iospec' values for rendering in HTML
  and JSON.

v0.2.0, 2013-04-21 -- API documentation
- 'APIDocumentationMaker' class scans an API tree and creates an API
  documentation dictionary.
- Customization of API documentation by subclassing 'APIDocumentationMaker'.
- 'api_doc_template.mak': Built-in Mako template that displays an API
  documentation web page. Contributed by Dan Kruse!
- 'APIDocumentationMaker.add_documentation_views' quickly adds API documentation
  endpoints (HTML and JSON) to a Pyramid web application.

v0.3.0, 2013-04-30 -- Python 3.3.1
- Refactor to work with Python 3.3.1.
- Python 2.x no longer supported starting with this release.

v0.3.1, 2013-05-14 -- Catchall; 'Sequence' tree
- 'add_catchall': New function allows user to add 'catchall' endpoints.
- Request methods must be instances of new 'RequestMethod' class.
- Tuple locations and branches: Branch locations can be tuples of paths and/or
  request methods. Branch objects can be tuples of view callables or sub-trees.
- Sequence tree: API tree can be a list of 2-length tuples. This guarantees the
  order in which views are added to the Pyramid configurator.

v0.3.2, 2013-05-15 -- Catchall targeting
- 'target_view_kwargs', 'target_request_method': New parameters to
  'add_catchall' function.
