Jsonpickle

====
* Python 3.7 `collections.Iterator` deprecation warnings have been fixed.
(229).

* Improved Pandas support for datetime and complex numbers. (+245)

====
* *NOTE* jsonpickle no longer supports Python2.6, or Python3 < 3.4.
The officially supported Python versions are now 2.7 and 3.4+.

* Improved Pandas and Numpy support. (+227)

* Improved support for pickling iterators. (+216)

* Better support for the stdlib `json` module when `simplejson`
is not installed. (+217)

* jsonpickle will now output python3-style module names when
pickling builtins methods or functions. (+223)

* jsonpickle will always flatten primitives, even when ``max_depth``
is reached, which avoids encoding unicode strings into their
``u'string'`` representation. (+207) (180) (198).

* Nested classes are now supported on Python 3. (+206) (176).

* Better support for older (pre-1.9) versions of numpy (+195).

======
* Better support for SQLAlchemy (180).

* Better support for NumPy and SciKit-Learn. (184).

* Better support for dict sub-classes (156).

======
* Better support for objects that implement the reduce protocol. (+170)
This backward-incompatible change removes the SimpleReduceHandler.
Any projects registering that handler for a particular type should
instead remove references to the handler and jsonpickle will now
handle those types directly.

======
* Arbitrary byte streams are now better supported. (143)

* Better support for NumPy data types. The Python3 NumPy support
is especially robust.

* Fortran-ordered based NumPy arrays are now properly serialized.

======
* UUID objects can now be serialized (130)

* Added `set_decoder_options` method to allow decoder specific options
equal to `set_encoder_options`.

* Int keys can be encoded directly by e.g. demjson by passing
`numeric_keys=True` and setting its backend options via
`jsonpickle.set_encoder_options('demjson', strict=False)`.

* Newer Numpy versions (v1.10+) are now supported.
