------------------------
* Don't validate database names on the client side. This means some methods
dealing with database names can return different exceptions than before.
* Use HTTP socket more efficiently to avoid the Nagle algorithm, greatly
improving performace. Note: add the ``{nodelay, true}`` option to the CouchDB
server's httpd/socket_options config.
* Add support for show and list functions.
* Add support for calling update handlers.
* Add support for purging documents.
* Add ``iterview()`` for more efficient iteration over large view results.
* Add view cleanup API.
* Enhance ``Server.stats()`` to optionally retrieve a single set of statistics.
* Implement ``Session`` timeouts.
* Add ``error`` property to ``Row`` objects.
* Add ``default=None`` arg to ``mapping.Document.get()`` to make it a little more
dict-like.
* Enhance ``Database.info()`` so it can also be used to get info for a design
doc.
* Add view definition options, e.g. collation.
* Fix support for authentication in dump/load tools.
* Support non-ASCII document IDs in serialization format.
* Protect ``ResponseBody`` from being iterated/closed multiple times.
* Rename iteration method for ResponseBody chunks to ``iterchunks()`` to
prevent usage for non-chunked responses.
* JSON encoding exceptions are no longer masked, resulting in better error
messages.
* ``cjson`` support is now deprecated.
* Fix ``Row.value`` and ``Row.__repr__`` to never raise exceptions.
* Fix Python view server's reduce to handle empty map results list.
* Use locale-independent timestamp identifiers for HTTP cache.
* Don't require setuptools/distribute to install the core package. (Still
needed to install the console scripts.)
