0.1.0
	- initial release
0.1.1
	- bugfixes
0.1.2
	- MOAR bug fixes
0.1.3
	- Fixed issues with pagination
	- Fixed issue where some values were not copied

0.1.4
	- Fixed deepcopy of shared resources (specifically self._es)

0.2.0
	- Calls to _create_search_params() create the native parameters to send to
	  elastic search and then remove the settings from the object. This allows
	  the collection object to be used for a new search. The drawback is
	  subsequent calls to all() will not work as expected.
	- added functionality for one() to return the first result of a query
	- Raises AttributeError if an attribute doesn't exist (previously returned
	  None but we have now considered this a bug)
	- Fixed bugs related to _set_by_query not being set
	- Fixed _deleted not getting set
	- Added relationship functionality
		- relationships can be specified on single columns
		- setting of a model on a relationship attribute does not yet work

0.2.1
	- reverted _create_search_params() change. Search paramters stay. Broke
	  too much stuff.
	- added clear_previous_search() to clear the search and reuse the
	  collection

0.2.2
	- bugfix to make VWCollection extend object

0.2.3
	- added function for geo searches

0.2.4
	- added sort()
	- added range()
	- BUG: range() doesn't work with other searches. To be fixed.

0.2.5
	- drew fixed broken delete()

0.2.6
	- ???

0.2.7
	- added delete() and delete_in() to collections

0.2.8
	- added commit() to bulk commit

0.2.9
	- bulk commit now returns the status of each commit
	- fixed date time format to work with bulk commit

0.2.10
	- added callback argument to commit

0.2.11
	- fixed collection calling wrong variable name when a custom index is
	  specfied
	- velociwrapper.__version__ returns the version number of the module now

0.2.12
	- allow _create_source_document() to have a specified date or datetime
	  format
	- fixed to_dict() to return date_time format in true ISO 0000-00-00
	  00:00:00
	- fixed date object creation being turned into datetime

0.2.13
	- fix get_in() to properly use _create_obj_list()
	- get_in() no longer catches exceptions (was returning an empty list)
	- _create_obj_list() filters out docs that returned found: False to
	  prevent an exception when creating the object
	  - this has the effect of returning all found documents from list calls
	  - instead of throwing exceptions / returning empty if a single doc fails
	  - we believe this was the original intended behavior
	- Fixed get_like_this()

0.2.14
	- fixed all() and search() (broken by the last update!)

0.2.15
	- fixed empty list passed to get_in() throwing exception

1.0.0
	- Split the module into multiple files
	- moved module configuration into velociwrapper.config
	- added types that coorespond to types used in ElasticSearch
	- added mapper tools to include reindex and create index functionality
	- changed filter_by() to use Query DSL
		- intellegently uses filters and falls back to queries when filtering
		  is not possible
		- filter mode works like exact()
		- id/ids key creates the special "ids" filter
	- added exact()
		- search for the exact phrase
		- can be combined with other queries using filter_by (but not ids)
		- will warn if the search is a string but the field is analyzed
		- can accept a list
	- range() now works with other searchs
	- search() may not always work with other searches due to nature of
	  QueryDSL
	- wrote some documentation in the README.rst

1.0.1
	- fixed es_types.is_analyzed returning False on lists and objects
	- fixed syntax error in collections, prevented filter_by kwargs from
	  accepting list values

1.0.2
	- fixed date parsing when converting to ESType
	- changed Date() and DateTime() to accept a date or datetime (respectivly)
	  on __init__()
	- fixed incorrect version number
	- changed setup.py to use the version from the module

1.0.3
	- fixed datetimes being converted to date
	- fixed microseconds being added to datetimes sent to the server (and
	  throwing exceptions)

1.0.4
	- fixed a bug that prevented defaults from being set when objects are
	  created

1.0.5
	- fixed so VWBase objects can be pickled

1.0.6
	- fixed collections references VWBase before it was imported

1.0.7
	- fixed datetime sending "datetime" as type to Elasticsearch (should send
	  date)

1.0.8
	- adds Array() type to ESTypes. Allows to specify an array of various
	  ESTypes

1.0.9
	- fixes pickling VWBase objects causing existing instances to lose
	  connection to elasticsearch (because the _es attribute is a static
	  attribute)
	- fixes mapper.reindex() to ignore subclasses that have no __type__
	  attribute. Such subclasses are treated as helpers that actual models are
	  derived from

1.0.10
	- added get_server_mapping() to Mapper. Allows inspection of what the
	  server actually has rather than what the code says.
	- fixed GeoPoint ESType returning the wrong type to elasticsearch
	- fixed setup.py failing due to missing imports when looking for version
	  before dependencies are resolved.
	- updated documentation

1.0.11
	- added multi_match()

1.0.12
	- fixed body not being propertly specified on reindex(). Caused explicit
	  mapping to be deleted

2.0 
	- rewrite of much of the internal query system
	- created qdsl.py module to output parts of Query DSL by calling functions
	- created querybuilder class that uses the QDSL functions and represents
	  the internal query state
		- much easier to chain calls together
		- no longer has to traverse the tree of JSON/dictionary to find where
		  to place new arguments
		- all search methods (in collection.py) now use the querybuilder / qdsl
	- Created VWCollectionGen generator object which is now returned by all()
	  and get_in()
		- vastly improves performance on large queries
		- items in the generator can still be referenced by index
	- added callbacks / events
		- several built-in events
		- events can be added and triggered
		- global event / callback system. Callbacks added to models exist for
		  all models of the same type

2.0.5 
	- consolidated version number
	- fixed a bug in callbacks
	- fixed bool type only accepting integers
	- fixed _create_obj() being called multiple times
	- fixed collection generator crash when a document has no _source

2.0.6
	- first public release
	- fixed version numbers
