Simplejson

* Rewrote test suite with unittest and doctest (no more nosetest dependency)
* Better PEP 7 and PEP 8 source compliance
* Removed simplejson.jsonfilter demo module
* simplejson.jsonfilter is no longer included

* Optional C extension for accelerating the decoding of JSON strings
* Command line interface for pretty-printing JSON (via python -msimplejson)
* Decoding of integers and floats is now extensible (e.g. to use Decimal) via
parse_int, parse_float options.
* Subversion and issue tracker moved to google code:
http://code.google.com/p/simplejson/
* "/" is no longer escaped, so if you're embedding JSON directly in HTML
you'll want to use .replace("/", "\\/") to prevent a close-tag attack.

* Improves encoding performance with an optional C extension to speed up
str/unicode encoding (by 10-150x or so), which yields an overall speed
boost of 2x+ (JSON is string-heavy).
* Support for encoding unicode code points outside the BMP to UTF-16
surrogate code pairs (specified by the Strings section of RFC 4627).

* Improved str support for encoding. Previous versions of simplejson
integrated strings directly into the output stream, this version ensures
they're of a particular encoding (default is UTF-8) so that the output
stream is valid.

* Better Python 2.5 compatibility
* Better Windows compatibility
* indent encoding parameter for pretty printing
* separators encoding parameter for generating optimally compact JSON

* The optional object_hook function is called upon decoding of any JSON
object literal, and its return value is used instead of the dict that
would normally be used. This can be used to efficiently implement
features such as JSON-RPC class hinting, or other custom decodings of
JSON. See the documentation for more information.
