=== 1.2.0
- Fixed composite key generation not to replace all
  special chars with dashes.

- Memory optimizations, now wrapping the mongo cursor.

- Fixed memoization on has_many_related assocations.

- Fixed pagination on embedded associations

- Fixed after_update callback not getting fired.

- When a connection failure occurs, Mongoid tried to
  retry the operation up to a configurable time.

- Mongoid now supports a configuration with a master
  and multiple read slaves. It will direct all writes
  to the master and all reads to the slaves. In the case
  of a write, subsequent reads will be directed to the
  master up to configurable number to try and counter
  the 2 second slave sync delay.

- Fixed issue with criteria exclusion queries with ids.

- Mongoid only executes a count when explicitly paginating.

- Fixed Criteria offset to be a getter or setter

- Added indexes to foreign keys on belongs_to_related
  associations.

- General code refactorings/cleanup

=== 1.1.4
- Refactorings in preparation for next feature push.

- Associations may now have anonymous extensions.

- Ruby 1.9 compatibility updates. (brainopia)

- Document.to_json accepts options. (jsmestad)

=== 1.1.3
- Nil can be passed into methods that set attributes.

- Mongoid.config can now take a block.

- Allow named_scopes and criteria class methods on
  has_many_related if related is a Mongoid document.

- Document.find can now take an array of ids.

=== 1.1.2
- Fixing issues with updates to parents.

=== 1.1.1
- Document.create raises validations error, not no
  method error on self.errors (Rick Frankel)

- Support default values that respond_to?(:call)
  (procs/lambda) (ahoward)

- Added Mongoid.persist_in_safe_mode global config
  option.

- Minor optimization: don't evaluate default procs
  if it's not needed (brainopia)

=== 1.1.0
- Nil attributes no longer persist nil values to the
  database - the field will just not exist.

- create! and save! will now properly raise an error
  when a database operation fails. This is handled
  by using :safe => true as an option to
  collection.save.

- Setting blank numbers casts to nil.

- Criteria and named scopes can now be used on has
  many relationships. They can be chained with each
  other off the association chain.

- Mongoid can now determine if a document matches a
  mongodb selector without hitting the database via
  Document#matches?(selector).

- Overall performance improvements in all areas.

- Ruby 1.9 compatibility fixes.

- Has many related now supports finding by id or
  by an optional :all, :first, :last with a
  conditions hash.

=== 1.0.6

- Preventing the setting of empty values in attributes.

- Better inspect formatting

=== 1.0.5

- Has one and has many associations now set the parent
  object first before writing the attributes on
  #build and #create.

=== 1.0.4
- Modified criteria to use the querying class
  when instantiating documents if there are no
  subclasses.

- Floats that are empty strings or nil get
  defaulted to 0.0

=== 1.0.3
- Small performance improvements on finders

- Float.set allows setting of non-numeric string
  in order for validates_numericality_of to fail
  properly.

=== 1.0.2
- Named scopes get added functionality:

  - named scopes can now be criteria objects.

  - named scoped can now be procs with criteria.

  - named scopes and class methods that return
    criteria can be chained with each other.

- When calling save on an embedded document whose
  validation passes but the parent's validation
  fails, it will properly return false.

=== 1.0.1
- Documents now have named_scopes similar to
  ActiveRecord named scopes. Please see rdoc or
  specs for examples.

- Document#to_json properly works in all cases.

- ActiveSupport calls for inflections have been
  moved into the String::Inflections module.

- Updated dependency on Validatable to 2.0.1

=== 1.0.0
- Validations cleanup: Only before_validation and
  after_validation callbacks are supported now.

- Dynamic fields have reader and writer methods
  again, but only for instances where the dynamic
  attribute exists.

- Lots of refactoring, mostly coverting common
  fucntionality into modules for the upcoming rails
  2 and 3 gem split.

=== 0.12.0
- Has one now works as expected:

  - Has one associations will return nil, instead
    of the proxy if the association has not been
    set.

  - Building/creating a has one is no longer handled
    by calling the Document#association#build() or create(),
    this is now handled by Document#build_name and
    Document#create_name where "name" is the name
    of the has one association.

  - Passing a _type attribute to the #build_name
    and #create_name methods will build/create
    objects of that type, useful for creating
    specific subclasses.

  - The existing #build and #create methods will be
    removed in the next release.

- Removed all dynamic finders. If you need to have
  functionality similar to "find_or_(create|initialize)_by"
  you can use the 2 new finders:

  - Document.find_or_create_by(attributes): Will
    look for a document in the database with the
    supplied attributes, if found it will return the
    document otherwise will create a new one with
    the supplied attributes.

  - Document.find_or_initialize_by(attributes): Will
    look for a document in the database with the
    supplied attributes, if found it will return the
    document otherwise will instantiate a new one with
    the supplied attributes.

- Fixed issue with empty hashes and arrays not getting
  set on document instantiation.

=== 0.11.9
- Fixed issue with non-us time zones and formats
  parsing incorrectly.

- Fixed error when specifying field restrictions
  in criteria and not providing the _type. It
  will now automaticall get added if it is not
  present.

- Slight cleanup of delegated methods in Document.

- Dynamic attributes no longer create setters and
  getters on the class. They can be accessed from
  the attributes hash directly. If they are used
  frequently it is preferrable to just add a field
  to the class manually.

- Criteria#min no longer always returns 0.0.

=== 0.11.8
- Added #min and #max to criteria which takes a
  single field argument.

=== 0.11.7
- Added #sum to criteria which takes a single field
  to aggregate on. Example: Person.sum(:age) would
  return a float that was the sum of all people's
  ages in the db.

- Fixed issue with queries from parent classes always
  casting the returned documents to the parent.

- Fixed singleton require issue.

- Group queries now run as db commands

=== 0.11.6
- Allow namespaced documents to default with:
  "namespace_modelname"

- Fixed indexing of _type field to only happen on root
  classes.

- Fixed creation of empty collections for embedded documents.

- Document.store_in now properly resets the collection
  if the collection had already been accessed.

- Document.find(nil) now raises
  Mongoid::Errors::InvalidOptions

=== 0.11.5
- Removed dependency on mongo_ext, since latest version
  was breaking on various operating systems.
=== 0.11.4
- Fixed issue with dynamic fields: checking whether
  the document responded to the attribute's method
  should have checked the setter and not the getter

- Fixed has_one associations not being able to be
  set to nil.

=== 0.11.3
- Fixed issue with Document#save! not calling before
  and after create callbacks if document is new

=== 0.11.2
- Fixing bug where has many and has one relational
  associations create method did not return the
  associated document

=== 0.11.1
- Querying for classes that have subclasses will also
  return the subclasses as well, similar to
  ActiveRecord.

- Adding configuration option allow_dynamic_fields. This
  defaults to true and if set to false will raise an
  error when trying to set an attribute on an object
  that does not have a corresponding field defined.

=== 0.11.0
- Set the collection name to store a document in via:
  Document.store_in :collection_name

- Initial inheritance support:

  - Documents and their associations can now have an
    infinite number of subclasses.

  - Has many and has one associations can build or
    create specific subclasses by providing an optional
    class as the last parameter to the #create and
    #build methods on the respective associations.

  - Querying for specific subclasses will only return
    those documents which were saved as that subclass,
    even though the hierarchy is stored in the same
    collection.

  - Deletion of subclass documents will only delete
    documents of that type, even though they all exist
    in the same collection. #delete_all and #destroy_all
    also support this behavoir.

- Updated mongo and mongo_ext dependencies to 0.18.2

- Fixed save on new documents to return true instead
  of the document itself.

=== 0.10.6
- Fixed bug when trying to set empty strings on number
  fields. (TypeError: can't convert Fixnum into String)

- Document.delete_all now drops the collection if
  conditions are empty or nil.

=== 0.10.5

- Documents that are embedded not properly respond to
  Document#destroy and Document#delete.

- Documents can now be saved sans validation with
  Document#save(false)

=== 0.10.4

- Documents no longer inherit from Mongoid::Document.
  Please include Mongoid::Document in all your models now.

- Config module added, you can now set one option:
  Mongoid.raise_not_found_error = (true|false)

  - When set to false, a Mongoid::Errors::DocumentNotFound
    will NOT get thrown when performing a Document.find(id)
    that does not return a document from the database.
    This defaults to true.

- Mongoid::Document.collection_name macro added. You can
  now set the name of the database collection to persist to.

- Mongoid::Criteria#select becomes Mongoid::Criteria#only
