+Doctrine ORM is an object-relational mapper for PHP 7.1+ that provides transparent persistence
 for PHP objects. It sits on top of a powerful database abstraction layer (DBAL). One of its key features
 is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL),

+# Upgrade to 2.13
+
+## Deprecated `QueryBuilder` methods and constants.
+
+1. The `QueryBuilder::getState()` method has been deprecated as the builder state is an internal concern.
+2. Relying on the type of the query being built by using `QueryBuilder::getType()` has been deprecated.
+   If necessary, track the type of the query being built outside of the builder.
+
+The following `QueryBuilder` constants related to the above methods have been deprecated:
+
+1. `SELECT`,
+2. `DELETE`,
+3. `UPDATE`,
+4. `STATE_DIRTY`,
+5. `STATE_CLEAN`.
+
+## Deprecated omitting only the alias argument for `QueryBuilder::update` and `QueryBuilder::delete`
+
+When building an UPDATE or DELETE query and when passing a class/type to the function, the alias argument must not be omitted.
+
+### Before
+
+```php
+$qb = $em->createQueryBuilder()
+    ->delete('User u')
+    ->where('u.id = :user_id')
+    ->setParameter('user_id', 1);
+```
+
+### After
+
+```php
+$qb = $em->createQueryBuilder()
+    ->delete('User', 'u')
+    ->where('u.id = :user_id')
+    ->setParameter('user_id', 1);
+```
+
+## Deprecated using the `IDENTITY` identifier strategy on platform that do not support identity columns
+
+If identity columns are emulated with sequences on the platform you are using,
+you should switch to the `SEQUENCE` strategy.
+
+## Deprecated passing `null` to `Doctrine\ORM\Query::setFirstResult()`
+
+`$query->setFirstResult(null);` is equivalent to `$query->setFirstResult(0)`.
+
+## Deprecated calling setters without arguments
+
+The following methods will require an argument in 3.0. Pass `null` instead of
+omitting the argument.
+
+* `Doctrine\ORM\Event\OnClassMetadataNotFoundEventArgs::setFoundMetadata()`
+* `Doctrine\ORM\AbstractQuery::setHydrationCacheProfile()`
+* `Doctrine\ORM\AbstractQuery::setResultCache()`
+* `Doctrine\ORM\AbstractQuery::setResultCacheProfile()`
+
+## Deprecated passing invalid fetch modes to `AbstractQuery::setFetchMode()`
+
+Calling `AbstractQuery::setFetchMode()` with anything else than
+`Doctrine\ORM\Mapping::FETCH_EAGER` results in
+`Doctrine\ORM\Mapping::FETCH_LAZY` being used. Relying on that behavior is
+deprecated and will result in an exception in 3.0.
+
+## Deprecated `getEntityManager()` in `Doctrine\ORM\Event\OnClearEventArgs` and `Doctrine\ORM\Event\*FlushEventArgs`
+
+This method has been deprecated in:
+
+* `Doctrine\ORM\Event\OnClearEventArgs`
+* `Doctrine\ORM\Event\OnFlushEventArgs`
+* `Doctrine\ORM\Event\PostFlushEventArgs`
+* `Doctrine\ORM\Event\PreFlushEventArgs`
+
+It will be removed in 3.0. Use `getObjectManager()` instead.
+
+## Prepare split of output walkers and tree walkers
+
+In 3.0, `SqlWalker` and its child classes won't implement the `TreeWalker`
+interface anymore. Relying on that inheritance is deprecated.
+
+The following methods of the `TreeWalker` interface have been deprecated:
+
+* `setQueryComponent()`
+* `walkSelectClause()`
+* `walkFromClause()`
+* `walkFunction()`
+* `walkOrderByClause()`
+* `walkOrderByItem()`
+* `walkHavingClause()`
+* `walkJoin()`
+* `walkSelectExpression()`
+* `walkQuantifiedExpression()`
+* `walkSubselect()`
+* `walkSubselectFromClause()`
+* `walkSimpleSelectClause()`
+* `walkSimpleSelectExpression()`
+* `walkAggregateExpression()`
+* `walkGroupByClause()`
+* `walkGroupByItem()`
+* `walkDeleteClause()`
+* `walkUpdateClause()`
+* `walkUpdateItem()`
+* `walkWhereClause()`
+* `walkConditionalExpression()`
+* `walkConditionalTerm()`
+* `walkConditionalFactor()`
+* `walkConditionalPrimary()`
+* `walkExistsExpression()`
+* `walkCollectionMemberExpression()`
+* `walkEmptyCollectionComparisonExpression()`
+* `walkNullComparisonExpression()`
+* `walkInExpression()`
+* `walkInstanceOfExpression()`
+* `walkLiteral()`
+* `walkBetweenExpression()`
+* `walkLikeExpression()`
+* `walkStateFieldPathExpression()`
+* `walkComparisonExpression()`
+* `walkInputParameter()`
+* `walkArithmeticExpression()`
+* `walkArithmeticTerm()`
+* `walkStringPrimary()`
+* `walkArithmeticFactor()`
+* `walkSimpleArithmeticExpression()`
+* `walkPathExpression()`
+* `walkResultVariable()`
+* `getExecutor()`
+
+The following changes have been made to the abstract `TreeWalkerAdapter` class:
+
+* All implementations of now-deprecated `TreeWalker` methods have been
+  deprecated as well.
+* The method `setQueryComponent()` will become protected in 3.0. Calling it
+  publicly is deprecated.
+* The method `_getQueryComponents()` is deprecated, call `getQueryComponents()`
+  instead.
+
+On the `TreeWalkerChain` class, all implementations of now-deprecated
+`TreeWalker` methods have been deprecated as well.  However, `SqlWalker` is
+unaffected by those deprecations and will continue to implement all of those
+methods.
+
+## Deprecated passing `null` to `Doctrine\ORM\Query::setDQL()`
+
+Doing `$query->setDQL(null);` achieves nothing.
+
+## Deprecated omitting second argument to `NamingStrategy::joinColumnName`
+
+When implementing `NamingStrategy`, it is deprecated to implement
+`joinColumnName()` with only one argument.
+
+### Before
+
+```php
+<?php
+class MyStrategy implements NamingStrategy
+{
+    /**
+     * @param string $propertyName A property name.
+     */
+    public function joinColumnName($propertyName): string
+    {
+        // …
+    }
+}
+```
+
+### After
+
+For backward-compatibility reasons, the parameter has to be optional, but can
+be documented as guaranteed to be a `class-string`.
+
+```php
+<?php
+class MyStrategy implements NamingStrategy
+{
+    /**
+     * @param string       $propertyName A property name.
+     * @param class-string $className
+     */
+    public function joinColumnName($propertyName, $className = null): string
+    {
+        // …
+    }
+}
+```
+
+## Deprecated methods related to named queries
+
+The following methods have been deprecated:
+
+- `Doctrine\ORM\Query\ResultSetMappingBuilder::addNamedNativeQueryMapping()`
+- `Doctrine\ORM\Query\ResultSetMappingBuilder::addNamedNativeQueryResultClassMapping()`
+- `Doctrine\ORM\Query\ResultSetMappingBuilder::addNamedNativeQueryResultSetMapping()`
+- `Doctrine\ORM\Query\ResultSetMappingBuilder::addNamedNativeQueryEntityResultMapping()`
+
+## Deprecated classes related to Doctrine 1 and reverse engineering
+
+The following classes have been deprecated:
+
+- `Doctrine\ORM\Tools\ConvertDoctrine1Schema`
+- `Doctrine\ORM\Tools\DisconnectedClassMetadataFactory`
+
+## Deprecate `ClassMetadataInfo` usage
+
+It is deprecated to pass `Doctrine\ORM\Mapping\ClassMetadataInfo` instances
+that are not also instances of `Doctrine\ORM\ClassMetadata` to the following
+methods:
+
+- `Doctrine\ORM\Mapping\Builder\ClassMetadataBuilder::__construct()`
+- `Doctrine\ORM\Mapping\Driver\DatabaseDriver::loadMetadataForClass()`
+- `Doctrine\ORM\Tools\SchemaValidator::validateClass()`
+
+# Upgrade to 2.12
+
+## Deprecated the `doctrine` binary.
+
+The documentation explains how the console tools can be bootstrapped for
+standalone usage.
+
+The method `ConsoleRunner::printCliConfigTemplate()` is deprecated because it
+was only useful in the context of the `doctrine` binary.
+
+## Deprecate omitting `$class` argument to `ORMInvalidArgumentException::invalidIdentifierBindingEntity()`
+
+To make it easier to identify understand the cause for that exception, it is
+deprecated to omit the class name when calling
+`ORMInvalidArgumentException::invalidIdentifierBindingEntity()`.
+
+## Deprecate `Doctrine\ORM\Tools\Console\Helper\EntityManagerHelper`
+
+Using a console helper to provide the ORM's console commands with one or
+multiple entity managers had been deprecated with 2.9 already. This leaves
+The `EntityManagerHelper` class with no purpose which is why it is now
+deprecated too. Applications that still rely on the `em` console helper, can
+easily recreate that class in their own codebase.
+
+## Deprecate custom repository classes that don't extend `EntityRepository`
+
+Although undocumented, it is currently possible to configure a custom repository
+class that implements `ObjectRepository` but does not extend the
+`EntityRepository` base class.
+
+This is now deprecated. Please extend `EntityRepository` instead.
+
+## Deprecated more APIs related to entity namespace aliases
+
+```diff
+-$config = $entityManager->getConfiguration();
+-$config->addEntityNamespace('CMS', 'My\App\Cms');
++use My\App\Cms\CmsUser;
+
+-$entityManager->getRepository('CMS:CmsUser');
++$entityManager->getRepository(CmsUser::class);
+```
+
+## Deprecate `AttributeDriver::getReader()` and `AnnotationDriver::getReader()`
+
+That method was inherited from the abstract `AnnotationDriver` class of
+`doctrine/persistence`, and does not seem to serve any purpose.
+
+## Un-deprecate `Doctrine\ORM\Proxy\Proxy`
+
+Because no forward-compatible new proxy solution had been implemented yet, the
+current proxy mechanism is not considered deprecated anymore for the time
+being. This applies to the following interfaces/classes:
+
+* `Doctrine\ORM\Proxy\Proxy`
+* `Doctrine\ORM\Proxy\ProxyFactory`
+
+These methods have been un-deprecated:
+
+* `Doctrine\ORM\Configuration::getAutoGenerateProxyClasses()`
+* `Doctrine\ORM\Configuration::getProxyDir()`
+* `Doctrine\ORM\Configuration::getProxyNamespace()`
+
+Note that the `Doctrine\ORM\Proxy\Autoloader` remains deprecated and will be removed in 3.0.
+
+## Deprecate helper methods from `AbstractCollectionPersister`
+
+The following protected methods of
+`Doctrine\ORM\Cache\Persister\Collection\AbstractCollectionPersister`
+are not in use anymore and will be removed.
+
+* `evictCollectionCache()`
+* `evictElementCache()`
+
+## Deprecate `Doctrine\ORM\Query\TreeWalkerChainIterator`
+
+This class won't have a replacement.
+
+## Deprecate `OnClearEventArgs::getEntityClass()` and `OnClearEventArgs::clearsAllEntities()`
+
+These methods will be removed in 3.0 along with the ability to partially clear
+the entity manager.
+
+## Deprecate `Doctrine\ORM\Configuration::newDefaultAnnotationDriver`
+
+This functionality has been moved to the new `ORMSetup` class. Call
+`Doctrine\ORM\ORMSetup::createDefaultAnnotationDriver()` to create
+a new annotation driver.
+
+## Deprecate `Doctrine\ORM\Tools\Setup`
+
+In our effort to migrate from Doctrine Cache to PSR-6, the `Setup` class which
+accepted a Doctrine Cache instance in each method has been deprecated.
+
+The replacement is `Doctrine\ORM\ORMSetup` which accepts a PSR-6
+cache instead.
+
+## Deprecate `Doctrine\ORM\Cache\MultiGetRegion`
+
+The interface will be merged with `Doctrine\ORM\Cache\Region` in 3.0.
+
+# Upgrade to 2.11
+
+## Rename `AbstractIdGenerator::generate()` to `generateId()`
+
+Implementations of `AbstractIdGenerator` have to override the method
+`generateId()` without calling the parent implementation. Not doing so is
+deprecated. Calling `generate()` on any `AbstractIdGenerator` implementation
+is deprecated.
+
+## PSR-6-based second level cache
+
+The second level cache has been reworked to consume a PSR-6 cache. Using a
+Doctrine Cache instance is deprecated.
+
+* `DefaultCacheFactory`: The constructor expects a PSR-6 cache item pool as
+  second argument now.
+* `DefaultMultiGetRegion`: This class is deprecated in favor of `DefaultRegion`.
+* `DefaultRegion`:
+  * The constructor expects a PSR-6 cache item pool as second argument now.
+  * The protected `$cache` property is deprecated.
+  * The properties `$name` and `$lifetime` as well as the constant
+   `REGION_KEY_SEPARATOR` and the method `getCacheEntryKey()` are flagged as
+   `@internal` now. They all will become `private` in 3.0.
+  * The method `getCache()` is deprecated without replacement.
+
+## Deprecated: `Doctrine\ORM\Mapping\Driver\PHPDriver`
+
+Use `StaticPHPDriver` instead when you want to programmatically configure
+entity metadata.
+
+You can convert mappings with the `orm:convert-mapping` command or more simply
+in this case, `include` the metadata file from the `loadMetadata` static method
+used by the `StaticPHPDriver`.
+
+## Deprecated: `Setup::registerAutoloadDirectory()`
+
+Use Composer's autoloader instead.
+
+## Deprecated: `AbstractHydrator::hydrateRow()`
+
+Following the deprecation of the method `AbstractHydrator::iterate()`, the
+method `hydrateRow()` has been deprecated as well.
+
+## Deprecate cache settings inspection
+
+Doctrine does not provide its own cache implementation anymore and relies on
+the PSR-6 standard instead. As a consequence, we cannot determine anymore
+whether a given cache adapter is suitable for a production environment.
+Because of that, functionality that aims to do so has been deprecated:
+
+* `Configuration::ensureProductionSettings()`
+* the `orm:ensure-production-settings` console command

+Accessing private/protected properties/methods of the same class from different instance
+========================================================================================
+
+.. sectionauthor:: Michael Olsavsky (olsavmic)
+
+As explained in the :doc:`restrictions for entity classes in the manual <../reference/architecture>`,
+it is dangerous to access private/protected properties of different entity instance of the same class because of lazy loading.
+
+The proxy instance that's injected instead of the real entity may not be initialized yet
+and therefore not contain expected data which may result in unexpected behavior.
+That's a limitation of current proxy implementation - only public methods automatically initialize proxies.
+
+It is usually preferable to use a public interface to manipulate the object from outside the `$this`
+context but it may not be convenient in some cases. The following example shows how to do it safely.

+.. _attrref_associationoverride:
+
+#[AssociationOverride]
+~~~~~~~~~~~~~~~~~~~~~~
+
+In an inheritance hierarchy this attribute allows to override the
+assocation mapping definitions of the parent mappings. It needs to be nested
+within a ``#[AssociationOverrides]`` on the class level.
+
+Required parameters:
+
+-  **name**: Name of the association mapping to overwrite.
+
+Optional parameters:
+
+-  **joinColumns**: A list of nested ``#[JoinColumn]`` declarations.
+-  **joinTable**: A nested ``#[JoinTable]`` declaration in case of a many-to-many overwrite.
+-  **inversedBy**: The name of the inversedBy field on the target entity side.
+-  **fetch**: The fetch strategy, one of: EAGER, LAZY, EXTRA_LAZY.
+

+    - A cascading ``remove`` operation (as indicated e. g. by ``cascade: ['remove']``
+      or ``cascade: ['all']`` in the mapping configuration) is not being performed
+      for associated entities. You can rely on database level cascade operations by

+

-Lifecycle Events
-----------------
-
-The ``EntityManager`` and ``UnitOfWork`` classes trigger a bunch of
-events during the life-time of their registered entities.
-
-
-
--  ``preRemove`` - The ``preRemove`` event occurs for a given entity
-   before the respective ``EntityManager`` remove operation for that
-   entity is executed.  It is not called for a DQL ``DELETE`` statement.
--  ``postRemove`` - The ``postRemove`` event occurs for an entity after the
-   entity has been deleted. It will be invoked after the database
-   delete operations. It is not called for a DQL ``DELETE`` statement.
--  ``prePersist`` - The ``prePersist`` event occurs for a given entity
-   before the respective ``EntityManager`` persist operation for that
-   entity is executed. It should be noted that this event is only triggered on
-   *initial* persist of an entity (i.e. it does not trigger on future updates).
--  ``postPersist`` - The ``postPersist`` event occurs for an entity after
-   the entity has been made persistent. It will be invoked after the
-   database insert operations. Generated primary key values are
-   available in the postPersist event.
--  ``preUpdate`` - The ``preUpdate`` event occurs before the database
-   update operations to entity data. It is not called for a DQL
-   ``UPDATE`` statement nor when the computed changeset is empty.
--  ``postUpdate`` - The ``postUpdate`` event occurs after the database
-   update operations to entity data. It is not called for a DQL
-   ``UPDATE`` statement.
--  ``postLoad`` - The postLoad event occurs for an entity after the
-   entity has been loaded into the current ``EntityManager`` from the
-   database or after the refresh operation has been applied to it.
--  ``loadClassMetadata`` - The ``loadClassMetadata`` event occurs after the
-   mapping metadata for a class has been loaded from a mapping source
-   (annotations/xml/yaml). This event is not a lifecycle callback.
--  ``onClassMetadataNotFound`` - Loading class metadata for a particular
-   requested class name failed. Manipulating the given event args instance
-   allows providing fallback metadata even when no actual metadata exists
-   or could be found. This event is not a lifecycle callback.
--  ``preFlush`` - The ``preFlush`` event occurs at the very beginning of
-   a flush operation.
--  ``onFlush`` - The ``onFlush`` event occurs after the change-sets of all
-   managed entities are computed. This event is not a lifecycle
-   callback.
--  ``postFlush`` - The ``postFlush`` event occurs at the end of a flush operation. This
-   event is not a lifecycle callback.
--  ``onClear`` - The ``onClear`` event occurs when the
-   ``EntityManager#clear()`` operation is invoked, after all references
-   to entities have been removed from the unit of work. This event is not
-   a lifecycle callback.
-
-
-.. warning::
-
-    Note that, when using ``Doctrine\ORM\AbstractQuery#toIterable()``, ``postLoad``
-    events will be executed immediately after objects are being hydrated, and therefore
-    associations are not guaranteed to be initialized. It is not safe to combine
-    usage of ``Doctrine\ORM\AbstractQuery#toIterable()`` and ``postLoad`` event
-    handlers.
-
-.. warning::
-
-    Note that the ``postRemove`` event or any events triggered after an entity removal
-    can receive an uninitializable proxy in case you have configured an entity to
-    cascade remove relations. In this case, you should load yourself the proxy in
-    the associated pre event.
-
-These can be hooked into by two different types of event
-listeners:
-
--  Lifecycle Callbacks are methods on the entity classes that are
-   called when the event is triggered. They receive some kind
-   of ``EventArgs`` instance.
--  Lifecycle Event Listeners and Subscribers are classes with specific callback
-   methods that receives some kind of ``EventArgs`` instance.
-
-The ``EventArgs`` instance received by the listener gives access to the entity,
-``EntityManager`` instance and other relevant data.
-
-.. note::
-
-    All Lifecycle events that happen during the ``flush()`` of
-    an ``EntityManager`` have very specific constraints on the allowed
-    operations that can be executed. Please read the
-    :ref:`reference-events-implementing-listeners` section very carefully
-    to understand which operations are allowed in which lifecycle event.
