### AbstractDoctrineBundle
* This bundle has been removed and the relevant code has been moved to the Doctrine bridge
### DoctrineBundle
* This bundle has been moved to the Doctrine organization
* added optional `group_by` property to `EntityType` that supports either a `PropertyPath` or a `\Closure` that is evaluated on the entity choices
* The `em` option for the `UniqueEntity` constraint is now optional (and should probably not be used anymore).

### SecurityBundle
* [BC BREAK] The custom factories for the firewall configuration are now
registered during the build method of bundles instead of being registered
by the end-user (you need to remove the 'factories' keys in your security
configuration).
* [BC BREAK] The Firewall listener is now registered after the Router one. It
means that specific Firewall URLs (like /login_check and /logout must now
have proper route defined in your routing configuration)
* [BC BREAK] refactored the user provider configuration. The configuration
changed for the chain provider and the memory provider:
Before:
``` yaml
security:
providers:
my_chain_provider:
providers: [my_memory_provider, my_doctrine_provider]
my_memory_provider:
users:
toto: { password: foobar, roles: [ROLE_USER] }
foo: { password: bar, roles: [ROLE_USER, ROLE_ADMIN] }
```
After:
``` yaml
security:
providers:
my_chain_provider:
chain:
providers: [my_memory_provider, my_doctrine_provider]
my_memory_provider:
memory:
users:
toto: { password: foobar, roles: [ROLE_USER] }
foo: { password: bar, roles: [ROLE_USER, ROLE_ADMIN] }
```
* [BC BREAK] Method `equals` was removed from `UserInterface` to its own new
`EquatableInterface`, now user class can implement this interface to override
the default implementation of users equality test.
* added a validator for the user password
* added 'erase_credentials' as a configuration key (true by default)
* added new events: `security.authentication.success` and `security.authentication.failure`
fired on authentication success/failure, regardless of authentication method,
events are defined in new event class: `Symfony\Component\Security\Core\AuthenticationEvents`.

### Filesystem
* created this new component
### Finder
* Finder::exclude() now supports an array of directories as an argument
### Form
* [BC BREAK] ``read_only`` field attribute now renders as ``readonly="readonly"``, use ``disabled`` instead

* made the translation catalogue configurable via the "translation_domain" option
* added Form::getErrorsAsString() to help debugging forms

* [BC BREAK] form and field names must start with a letter, digit or underscore
and only contain letters, digits, underscores, hyphens and colons
* [BC BREAK] changed default name of the prototype in the "collection" type
from "$$name$$" to "__name__". No dollars are appended/prepended to custom
names anymore.

* [BC BREAK] added SimpleChoiceList and LazyChoiceList as replacement of
ArrayChoiceList
* added ChoiceList and ObjectChoiceList to use objects as choices
* [BC BREAK] removed EntitiesToArrayTransformer and EntityToIdTransformer.
The former has been replaced by CollectionToArrayTransformer in combination
with EntityChoiceList, the latter is not required in the core anymore.
* [BC BREAK] renamed
* ArrayToBooleanChoicesTransformer to ChoicesToBooleanArrayTransformer
* ScalarToBooleanChoicesTransformer to ChoiceToBooleanArrayTransformer
* ArrayToChoicesTransformer to ChoicesToValuesTransformer
* ScalarToChoiceTransformer to ChoiceToValueTransformer
to be consistent with the naming in ChoiceListInterface.

selection) types now make use of addXxx() and removeXxx() methods in your
model

* removed the ContentTypeMimeTypeGuesser class as it is deprecated and never used on PHP 5.3
* added ResponseHeaderBag::makeDisposition() (implements RFC 6266)
* made mimetype to extension conversion configurable
* [BC BREAK] Moved all session related classes and interfaces into own namespace, as
`Symfony\Component\HttpFoudation\Session` and renamed classes accordingly.
* Added `FlashBag`. Flashes expire when retrieved by `get()` or `all()`.
This makes the implementation ESI compatible.
* Added `AutoExpireFlashBag` (default) to replicate Symfony 2.0.x auto expire behaviour of messages auto expiring
after one page page load. Messages must be retrived by `get()` or `all()`.
* [BC BREAK] Removed the `close()` method from the Session class
* Deprecated the following methods from the Session class: `setFlash()`, `setFlashes()`
`getFlash()`, `hasFlash()`, and `removeFlash()`. Use `getFlashBag() instead which returns a `FlashBagInterface`.
* `Session->clear()` now only clears session attributes as before it cleared flash messages and
attributes. `Session->getFlashBag()->all()` clears flashes now.
* Added `Symfony\Component\HttpFoundation\Session\Storage\AbstractSessionStorage` base class for
session storage drivers.
* Added `Symfony\Component\HttpFoundation\Session\Storage\SessionHandlerInterface` interface
which storage drivers should implement after inheriting from
`Symfony\Component\HttpFoundation\Session\Storage\AbstractSessionStorage` when writing custom
session save handlers. This interface is also compatible with PHP 5.4's SessionHandlerInterface.
* [BC BREAK] `SessionStorageInterface` methods removed: `write()`, `read()` and `remove()`. Added
`getBag()`, `registerBag()`.
* Moved attribute storage to `Symfony\Component\HttpFoundation\Attribute\AttributeBagInterface`.
* Added `Symfony\Component\HttpFoundation\Attribute\AttributeBag` to replicate attributes storage
behaviour from 2.0.x (default).
* Added `Symfony\Component\HttpFoundation\Attribute\NamespacedAttributeBag` for namespace session attributes.
* Session now implements `Symfony\Component\HttpFoundation\Session\SessionInterface` making
implementation customizable and portable.

* [BC BREAK] changed `MutableAclInterface::setParentAcl` to accept `null`, review your implementation to reflect this change.
### Serializer
* [BC BREAK] changed `GetSetMethodNormalizer`'s key names from all lowercased to camelCased (e.g. `mypropertyvalue` to `myPropertyValue`)
* [BC BREAK] convert the `item` XML tag to an array
``` xml
<?xml version="1.0"?>
<response>
<item><title><![CDATA[title1]]></title></item><item><title><![CDATA[title2]]></title></item>
</response>
```
Before:
Array()
