# 0.4.1 (2009-02-23)

> - amf0.Encoder.use_amf3 has been extended to cover all object types (Ticket:453,467)

> - property types on Django models will now encode as expected. (Ticket:480)

> - Django models.ForeignKey properties will be followed only if previously accessed outside of PyAMF. _[attr]_cache is no longer encoded. (Ticket:456)

> - Encoding {0:0, '0':1} will now raise an AttributeError. (Ticket:458)

> - Google AppEngine adapter improvements - see ticket for details (Ticket:479)

> - amf0.Encoder will encode all elements as AMF3 if use_amf3 option is set to True (Ticket:453)

> - Unicode handling in __repr__ functions has been improved (Ticket:455)

> - object attributes and dict keys are now utf8 encoded bytestrings. Python **kwargs doesn't accept unicode key objects. (Ticket:463)

>   System Message: WARNING/2 (`/var/folders/bu/bun4nN8wHjuhW8+DaEi4OU+++TI/-Tmp-/tmpj24gl9/CHANGES.txt`, line 22); backlink

>   Inline strong start-string without end-string.

> - Django models.TimeField, models.DateField will now be converted to the correct type (datetime.time and datetime.date respectively). fields.NOT_PROVIDED is also checked for by converting to pyamf.Undefined and back again. (Ticket:457)

# 0.4 (2009-01-18)

> - cpyamf now deals with exceptional floats the same way as pure python - especially on windows (Ticket:448)
> - Support for SQLAlchemy 0.5.1 (Ticket:449)
> - amf0.Encoder now has a use_amf3 flag which determines which XML type to return to the client (Ticket:435)
> - BufferedByteString.truncate(length) now actually does something useful (Ticket:444)
> - setup.py now gets the version number from pyamf/__init__.py source (Ticket:429)

# 0.4rc3 (2008-01-14)

> - Support for SQLAlchemy 0.5.0 (Ticket:436)
> - pyamf.util.DataTypeMixIn/cpyamf.util.BufferedByteStream can now encode/decode 24bit un/signed integers. (Ticket:422)
> - pyamf.util.StringIOProxy/cpyamf.util.BufferedByteStream both have new consume methods that will chop of the tail of the stream (already read stream). (Ticket:423)
> - Now checking for all types of supported xml lib types for encoding, but will only use the first implementation for decoding (Ticket:426)
> - fpconst dependancy is now only required if the platform requires it (Ticket:356)
> - Decoding negative timestamps on certain platforms (namely Windows) are now supported (Ticket:390)

# 0.4rc2 (2009-01-05)

> - Support for SQLAlchemy 0.4.0 (Ticket:410)

# 0.4rc1 (2008-12-31)

> - Support for encoding/decoding SQLAlchemy ORM objects with a new adapter. Lots of people involved in this one, but special thanks to Dave Thompson and Michael Van Tellingen for making this happen. (Ticket:277)
> - All gateways now log exceptions when exceptions are raised during en/decoding. (Ticket:394)
> - Flex messaging now uses correct static attributes for encoding. Determining static/dynamic attributes on objects is now easier (Ticket:357)
> - Added use_proxy option to amf3 which will automagically convert ObjectProxy to dict and ArrayCollection to list on decoding, and vice versa on encode. Thanks to dthompso for the excellent patch (Ticket:355)
> - flex.ArrayCollection now subclasses list instead of dict as non-int keys are not allowed. IList interface has been implemented. (Ticket:349)
> - Encoding registered subclass of list that define the 'externalised' metadata will be encoded as an object.
> - Encoders how have a 'strict' mode. Not generally useful for the time being but will help with developments in the future. Type mapped functions now require a second 'encoder' attribute. (Ticket:378)
> - Added adapter to handle the decimal module and, if strict is set to False, silently converts a Decimal instance to a float (Ticket:376)
> - ClassAlias can now be subclassed and three new methods have been added: applyAttributes, createInstance, getAttributes all which help to provide fine control for object/instance manipulation (Ticket:348)
> - Added support for __slots__ (Ticket:347)
> - Fixed problem when decoding objects that map to GAE db.Model objects with required properties (Ticket:342)
> - ByteArray now does not throw an error when used in the Remoting framework (Ticket:379)
> - A new adapter that converts sets.ImmutableSet and sets.Set to tuples before encoding. (Ticket:280)
> - A revamped google app engine adapter that checks for the _key attribute in an aliased class and first loads the object from the datastore and then applies that properties in the object stream. (Ticket:307)
> - New helper function to make it easier to manually add adapters (Ticket:350)
> - Ability to disable the c extension with passing --disable-ext to setup.py (Ticket:381, 391)
> - Python C-extension for the pyamf.util.BufferedByteStream class. Originally contributed by Gerard Escalante (Ticket:225, 405)
> - New API to add headers such as cookies in pyamf.remoting.client (Ticket:337)
> - Now clearing the context between remoting requests (Ticket:309)
> - Fixed issue with AMF3 class definition references (Ticket:341)
> - More helpful description for register_class args check (Ticket:334)
> - pyamf.register_class now checks to ensure that __init__ args do not have any arguments (Ticket:322)
> - Added RemoteObject support for AsyncMessage (Ticket:292)
> - pyamf.remoting.ErrorFault.__repr__ now displays the traceback info (if it exists). (Ticket:331)
> - Both Encoders will now raise pyamf.EncodeError if a function is encoded (Ticket:311)
> - Twisted Gateway would fall over when returning tuples (Ticket:313)
> - The remoting gateways now send a customizable Server header (Ticket:317)
> - The remoting client now sends a customizable User-Agent header (Ticket:306)
> - Added ability to set the HTTP referer in remoting client (Ticket:316)
> - Fixed issue where the AMF3 encoder assumed objects with a 'tag' attribute needed XML encoding. Reported by cy-man (Ticket:303)
> - Solved issue with repr for AbstractMessage. Reported by datafunk (Ticket:283)
> - Content-type was missing in POST requests from the AMF client. Reported by magog (Ticket:304)
