### Release 2.0.0 (August 20, 2015)

#### Breaking Changes

##### Unsaved deleted records are no longer removed from hasMany relationships and RecordArrays returned by the store

In Ember Data 1.13 once a record was marked as deleted it was removed from all of the RecordArrays and hasMany arrays it belongTo. This made it difficult to create UIs where a user could flag a record for deletion but still allow the user the ability to un-flag the record until the save request was made.

In Ember Data 2.0 a record will no longer be removed from hasMany relationships or RecordArrays until the delete has been acknowledged by the adapter. Although deleted records will be visible in hasMany relationships they will not be serialized when saving these relationships to the backend.

- Fix a regression where `currentState` was not defined on a record
  until the record a state change occured. https://github.com/emberjs/data/pull/3311

### Release 1.0.0-beta.19.1 (June 9, 2015)

- Pass store to inverseFor in removeEmbeddedForeignKey #3270 - @wecc
  https://github.com/emberjs/data/pull/3270

### Release 1.0.0-beta.19 (June 5, 2015)

#### Breaking Changes

##### Store Service moved to an Instance Initializer

In order to fix deprecations warning induced by Ember 1.12, the store service
is now injected as an instanceInitializer. As a consequence, if you had initializers
depending on the store, you should move them to an instance initializer as well,
and mark it as after: 'ember-data'.

- Removed support for DS.FixtureAdapter. You can use it as an addon, or
  build it using [Ember Giftwrap](https://github.com/ef4/ember-giftwrap).
  https://github.com/emberjs/ember-data-fixture-adapter/tree/master
- Removed support for passing factories to store methods. An example
  would be `store.find(App.Post, '1')`. Use the string form instead:
  `post` instead of `App.Post`. You can also use this [Ember Watson
  command](https://github.com/abuiles/ember-watson#ember-watsonconvert-ember-data-model-lookups)

### Release 1.0.0-beta.16 (March 23, 2015)

#### Breaking Changes

##### The store now passes snapshots instead of records to adapter methods

In 1.0.0-beta.15 serializers were updated to be passed snapshots instead of
records to prevent side-effects like fetching data when inspecting
relationships. This has now been extended to also include adapters methods.

The following adapter methods are now passed snapshots instead of records:

- `find(store, type, id, snapshot)`
- `findMany(store, type, ids, snapshots)`
- `findHasMany(store, snapshot, url, relationship)`
- `findBelongsTo(store, snapshot, url, relationship)`
- `createRecord(store, type, snapshot)`
- `updateRecord(store, type, snapshot)`
- `deleteRecord(store, type, snapshot)`

The signature of `buildURL(type, id, snapshot)` has also been updated to receive
snapshots instead of records.

This change removes the need for adapters to create snapshots manually using the
private API `record._createSnapshot()` to be able to pass snapshots to
serializers.

Snapshots are backwards-compatible with records (with deprecation warnings) and
it should be pretty straight forward to update current code to the public
Snapshot API:

```js
post.get('id')           => postSnapshot.id
post.get('title')        => postSnapshot.attr('title')
post.get('author')       => postSnapshot.belongsTo('author')
post.get('comments')     => postSnapshot.hasMany('comments')
post.constructor         => postSnapshot.type;
post.constructor.typeKey => postSnapshot.typeKey
```

If you need to access the underlying record of a snapshot you can do so by
accessing `snapshot.record`.

The full API reference of `DS.Snapshot` can be found [here](https://emberjs.com/api/data/classes/DS.Snapshot.html).

### Release 1.0.0-beta.15 (February 14, 2015)

#### Breaking Changes

##### serializer.serialize() now receives a Snapshot instead of a record instance
A snapshot represents the frozen state of a record at a particular
moment in time. Its initial purpose is to be passed to serializers
instead of the real record. This allows the serializer to examine the
current state of that record in the moment without triggering
side-effects, like loading relationships.

The serializer has a different API from a record for accessing
properties so you will know you are working with a snapshot. Using
`snapshot.get` is still supported for compatibility however it will
log a deprecated warning to encourage you to use the new apis.

To access attributes you should now use the `attr` function.

```js
// Ember Data 1.0.0-beta.14.1
post.get('title');
// Ember Data 1.0.0-beta.15
postSnapshot.attr('title');
```

To access a belongsTo relationship you should use `.belongsTo()` method.

```js
// Ember Data 1.0.0-beta.14.1
post.get('author');
// Ember Data 1.0.0-beta.15
postSnapshot.belongsTo('author');
```

To access a hasMany relationship you should use `.hasMany()` method.

```js
// Ember Data 1.0.0-beta.14.1
post.get('comments');
// Ember Data 1.0.0-beta.15
postSnapshot.hasMany('comments');
```

##### RecordArray.pushRecord and ManyArray.addRecord/removeRecord are deprecated

If you would like to add a new record to a `RecordArray` or a
`ManyArray` you should now use the `addObject` and `removeObject`
methods.

#### Changes

  * use package.json for ember addon
  * Initial implementation of the Snapshot API
  * Allow errors on arbitrary properties, not just defined attributes or relationships
  * Fix bug preventing hasMany relationships from correctly tracking simultaneous adds and removes.
  * remove unused code.

  * Use store.unloadRecord() in favor of store.dematerializeRecord()
  * Correctly trigger arrayContentDidChange when updating hasMany relationships
  * Warn if the user specifies a reflexive relationship without explicitly defining the inverse
  * bump ember-inflector dependency for HTMLBars compat
  * Add adapter.hasMany unique IDs test
  * Replace calls to `container` with `registry`
  * Dematerialize rejected _find() if record isEmpty
  * Add a Serializer base class
  * Make ManyArray.save() and RecordArray.save() return themselves
  * Added save() to ManyArray
  * idiomatic super usage.
  * Created `store.fetchById` and `store.fetchAll`.

  * fixes to load beta 14/14.1 sourcemaps in ember-cli
  * fix version for dropped <= Ember 1.7 support
  * generateIdForRecord gets type & object properties passed to it
  * Clarify store.find via findAll docs
  * Deprecate addRecord/removeRecord for ManyArray

### Ember Data 1.0.0-beta.14.1 (December 31, 2014)

#### Changes

  * Replace `<%= versionStamp %>` with actual version stamp. Thanks
    @tricknotes!
  * Fix sourcemap loading in Ember CLI and Rails.

### Ember Data 1.0.0-beta.14 (December 25, 2014)

#### Breaking Changes

##### `store.update()` has been deprecated

Calling `store.update()` has been deprecated in favor of `store.push()` now
handling partial payloads:

```javascript
var post = store.push('post', {
  id: 1,
  title: 'Ember.js is fantastic',
  author: 'Tomster'
});

post.get('title'); // => 'Ember.js is fantastic'
post.get('author'); // => 'Tomster'

store.push('post', { id: 1, author: 'Tom Dale' });

post.get('title'); // => 'Ember.js is fantastic'
post.get('author'); // => 'Tom Dale'
```

This also mean that properties missing in the payload will no longer be reset,
but stay the same.

If you need to reset values to null, you should have your server explicitly
send back null values in the payload:

```javascript
{
  "person": {
    "firstName": null,
    "lastName": null
    "role": "Computer Science Pioneer"
  }
}
```

If you cannot change your API and you desire this behavior, you can create a
serializer and do the logic yourself:

```javascript
// app/serializers/person.js
// or App.PersonSerializer if you aren't using Ember CLI
export default DS.RESTSerializer.extend({
  normalize: function(type, hash, prop) {
    hash = this._super(type, hash, prop);
    if (!hash.hasOwnProperty('firstName')){
      hash.firstName = null;
    }
    if (!hash.hasOwnProperty('lastName')){
      hash.lastName = null;
    }
    return hash;
  }
});
```

Or if you want to restore the old behavior for all of your models:

```javascript
// app/serializers/application.js
// or App.ApplicationSerializer
export default DS.RESTSerializer.extend({
  normalize: function(type, hash, prop) {
    hash = this._super(type, hash, prop);
    type.eachAttribute(function(key) {
      if (!hash.hasOwnProperty(key)) {
        hash[key] = null;
      }
    }, this);
    return hash;
  }
});
```

##### `store.metaForType()` has been deprecated

`store.metaForType()` has been deprecated because of it's ambiguous naming.
Please use `store.metadataFor()` to get metadata and `store.setMetadataFor()`
to set metadata.


##### `ManyArray`s are no longer `RecordArray`s
[ManyArray](https://emberjs.com/api/data/classes/DS.ManyArray.html),
the object Ember Data uses to represent `DS.hasMany` relationships has
been changed so it no longer extends from `RecordArray`. This means if
you were relying on the RecordArray's `content` property to access the
underlying array you will now need to use the `.toArray()` method.

```javascript
// Ember Data 1.0.0-beta.12
record.get('myHasManyRelationship').get('content').map(...);

// Ember Data 1.0.0-beta.14
record.get('myHasManyRelationship').toArray().map(...);
```

Additionally if you were using the `RecordArray`'s `.addRecord()` and
`.removeRecord()` methods you will now need to use the `.addObject()`
/ `.removeObject()` array methods.


#### Changes

* Fix references to buildURL in documentation
* fix canary build for recent Ember.Container refactors
* [DOC] Stop using deprecated `each` helper syntax
* Work around type check issues with MODEL_FACTORY_INJECTIONS.
* [DOC] Add page for `DS.PromiseManyArray`

* hasMany relationships are no longer `RecordArray`, but `ManyArray`. To access the underlying array use `relationship.toArray()` instead of `relationship.get('content')`.

### Ember Data 1.0.0-beta.12 (November 25, 2014)


##### Internet Explorer 8 Requires Ember 1.8

A bug in Ember 1.7's `Ember.create` method (which is a polyfill for
`Object.create`) combined with a bug in es5-shim's `Object.create` prevent us
from giving Ember Data users a good alternative to use. Internally, Ember Data
uses `Object.create` for efficient caches. Ember 1.8 ships a working
`Object.create` polyfill on `Ember.create` so if you are using Internet
Explorer 8 and Ember Data in production, you should upgrade to Ember 1.8 as
soon as you can.

If you are using browsers that provide `Object.create`, you do not need to do
any additional work here. This includes mobile browsers, evergreen browsers
(Chrome, Opera, Firefox), Safari, and IE9+.

##### Ember 1.7 Support Will Be Completely Dropped in Beta.13

Ember Data relies heavily on JavaScript language-level shims (such as the
`Object.create` issue mentioned above) and other useful internals that Ember
provides. Rather than creating our own detection algorithms and more polyfills
for broken code in Ember 1.7, we are deciding to drop 1.7 support in the next
release of Ember Data. We do so in order to not increase the final size of
Ember Data's build. You should upgrade to Ember 1.8 as soon as you can.

##### Observing `data` For Changes Has Been Removed

Although `model.get('data')` has been private in Ember Data for a long time, we
have noticed users may subscribe to changes on `data` for any change to the
model's attributes. This means that the following code:

```javascript
var Post = DS.Model.extend({
  doSomethingWhenDataChanges: function(){
    // do the work
  }.property('data')
});
```

**no longer works**. Instead, you should just watch each attribute like you
would with any `Ember.Object`:

```javascript
var Post = DS.Model.extend({
  name: DS.attr(),
  date: DS.attr(),
  doSomethingWhenDataChanges: function(){
    // do the work
  }.property('name', 'date')
});
```

For more details https://github.com/emberjs/data/issues/2339

* Bring back relationship parameter for findHasMany & findBelongsTo
* add es5-shim/sham requirement to README

* Don't use the DOM in the store tests
* Added an example of how to use the preload arg
* Added documentation for preload parameter
* [Documentation] typo in `find` documentation

### Ember Data 1.0.0-beta.9 _(August 18, 2014)_
