-Doctrine ORM is an object-relational mapper for PHP 8.1+ that provides transparent persistence
+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),
 inspired by Hibernate's HQL. This provides developers with a powerful alternative to SQL that maintains flexibility

-# Upgrade to 3.2
+# Upgrade to 2.20
 
-## Deprecate the `NotSupported` exception
+## Add `Doctrine\ORM\Query\OutputWalker` interface, deprecate `Doctrine\ORM\Query\SqlWalker::getExecutor()`
 
-The class `Doctrine\ORM\Exception\NotSupported` is deprecated without replacement.
+Output walkers should implement the new `\Doctrine\ORM\Query\OutputWalker` interface and create
+`Doctrine\ORM\Query\Exec\SqlFinalizer` instances instead of `Doctrine\ORM\Query\Exec\AbstractSqlExecutor`s.
+The output walker must not base its workings on the query `firstResult`/`maxResult` values, so that the 
+`SqlFinalizer` can be kept in the query cache and used regardless of the actual `firstResult`/`maxResult` values.
+Any operation dependent on `firstResult`/`maxResult` should take place within the `SqlFinalizer::createExecutor()`
+method. Details can be found at https://github.com/doctrine/orm/pull/11188.
 
-## Deprecate remaining `Serializable` implementation
+## Explictly forbid property hooks
 
-Relying on `SequenceGenerator` implementing the `Serializable` is deprecated
-because that interface won't be implemented in ORM 4 anymore.
+Property hooks are not supported yet by Doctrine ORM. Until support is added,
+they are explicitly forbidden because the support would result in a breaking
+change in behavior.
 
-The following methods are deprecated:
+Progress on this is tracked at https://github.com/doctrine/orm/issues/11624 .
 
-* `SequenceGenerator::serialize()`
-* `SequenceGenerator::unserialize()`
+## PARTIAL DQL syntax is undeprecated 
 
-## `orm:schema-tool:update` option `--complete` is deprecated
+Use of the PARTIAL keyword is not deprecated anymore in DQL, because we will be
+able to support PARTIAL objects with PHP 8.4 Lazy Objects and
+Symfony/VarExporter in a better way. When we decided to remove this feature
+these two abstractions did not exist yet.
 
-That option behaves as a no-op, and is deprecated. It will be removed in 4.0.
+WARNING: If you want to upgrade to 3.x and still use PARTIAL keyword in DQL
+with array or object hydrators, then you have to directly migrate to ORM 3.3.x or higher.
+PARTIAL keyword in DQL is not available in 3.0, 3.1 and 3.2 of ORM.
 
-## Deprecate properties `$indexes` and `$uniqueConstraints` of `Doctrine\ORM\Mapping\Table`
+## Deprecate `\Doctrine\ORM\Query\Parser::setCustomOutputTreeWalker()`
 
-The properties `$indexes` and `$uniqueConstraints` have been deprecated since they had no effect at all.
-The preferred way of defining indices and unique constraints is by
-using the `\Doctrine\ORM\Mapping\UniqueConstraint` and `\Doctrine\ORM\Mapping\Index` attributes.
-
-# Upgrade to 3.1
-
-## Deprecate `Doctrine\ORM\Mapping\ReflectionEnumProperty`
-
-This class is deprecated and will be removed in 4.0.
-Instead, use `Doctrine\Persistence\Reflection\EnumReflectionProperty` from
-`doctrine/persistence`.
-
-## Deprecate passing null to `ClassMetadata::fullyQualifiedClassName()`
-
-Passing `null` to `Doctrine\ORM\ClassMetadata::fullyQualifiedClassName()` is
-deprecated and will no longer be possible in 4.0.
-
-## Deprecate array access
-
-Using array access on instances of the following classes is deprecated:
-
-- `Doctrine\ORM\Mapping\DiscriminatorColumnMapping`
-- `Doctrine\ORM\Mapping\EmbedClassMapping`
-- `Doctrine\ORM\Mapping\FieldMapping`
-- `Doctrine\ORM\Mapping\JoinColumnMapping`
-- `Doctrine\ORM\Mapping\JoinTableMapping`
-
-# Upgrade to 3.0
-
-## BC BREAK: Calling `ClassMetadata::getAssociationMappedByTargetField()` with the owning side of an association now throws an exception
-
-Previously, calling
-`Doctrine\ORM\Mapping\ClassMetadata::getAssociationMappedByTargetField()` with
-the owning side of an association returned `null`, which was undocumented, and
-wrong according to the phpdoc of the parent method.
-
-If you do not know whether you are on the owning or inverse side of an association,
-you can use  `Doctrine\ORM\Mapping\ClassMetadata::isAssociationInverseSide()`
-to find out.
-
-## BC BREAK: `Doctrine\ORM\Proxy\Autoloader` no longer extends `Doctrine\Common\Proxy\Autoloader`
-
-Make sure to use the former when writing a type declaration or an `instanceof` check.
-
-## Minor BC BREAK: Changed order of arguments passed to `OneToOne`, `ManyToOne` and `Index` mapping PHP attributes
-
-To keep PHP mapping attributes consistent, order of arguments passed to above attributes has been changed
-so `$targetEntity` is a first argument now. This change affects only non-named arguments usage.
-
-## BC BREAK: AUTO keyword for identity generation defaults to IDENTITY for PostgreSQL when using `doctrine/dbal` 4
-
-When using the `AUTO` strategy to let Doctrine determine the identity generation mechanism for
-an entity, and when using `doctrine/dbal` 4, PostgreSQL now uses `IDENTITY`
-instead of `SEQUENCE` or `SERIAL`.
-* If you want to upgrade your existing tables to identity columns, you will need to follow [migration to identity columns on PostgreSQL](https://www.doctrine-project.org/projects/doctrine-dbal/en/4.0/how-to/postgresql-identity-migration.html)
-* If you want to keep using SQL sequences, you need to configure the ORM this way:
-```php
-use Doctrine\DBAL\Platforms\PostgreSQLPlatform;
-use Doctrine\ORM\Configuration;
-use Doctrine\ORM\Mapping\ClassMetadata;
-
-assert($configuration instanceof Configuration);
-$configuration->setIdentityGenerationPreferences([
-    PostgreSQLPlatform::CLASS => ClassMetadata::GENERATOR_TYPE_SEQUENCE,
-]);
-```
-
-## BC BREAK: Throw exceptions when using illegal attributes on Embeddable
-
-There are only a few attributes allowed on an embeddable such as `#[Column]` or
-`#[Embedded]`. Previously all others that target entity classes where ignored,
-now they throw an exception.
-
-## BC BREAK: Partial objects are removed
-
-- The `PARTIAL` keyword in DQL no longer exists.
-- `Doctrine\ORM\Query\AST\PartialObjectExpression`is removed.
-- `Doctrine\ORM\Query\SqlWalker::HINT_PARTIAL` and
-  `Doctrine\ORM\Query::HINT_FORCE_PARTIAL_LOAD` are removed.
-- `Doctrine\ORM\EntityManager*::getPartialReference()` is removed.
-
-## BC BREAK: `Doctrine\ORM\Persister\Entity\EntityPersister::executeInserts()` return type changed to `void`
-
-Implementors should adapt to the new signature, and should call
-`UnitOfWork::assignPostInsertId()` for each entry in the previously returned
-array.
-
-## BC BREAK: `Doctrine\ORM\Proxy\ProxyFactory` no longer extends abstract factory from `doctrine/common`
-
-It is no longer possible to call methods, constants or properties inherited
-from that class on a `ProxyFactory` instance.
-
-`Doctrine\ORM\Proxy\ProxyFactory::createProxyDefinition()` and
-`Doctrine\ORM\Proxy\ProxyFactory::resetUninitializedProxy()` are removed as well.
-
-## BC BREAK: lazy ghosts are enabled unconditionally
-
-`Doctrine\ORM\Configuration::setLazyGhostObjectEnabled()` and
-`Doctrine\ORM\Configuration::isLazyGhostObjectEnabled()` are now no-ops and
-will be deprecated in 3.1.0
-
-## BC BREAK: collisions in identity map are unconditionally rejected
-
-`Doctrine\ORM\Configuration::setRejectIdCollisionInIdentityMap()` and
-`Doctrine\ORM\Configuration::isRejectIdCollisionInIdentityMapEnabled()` are now
-no-ops and will be deprecated in 3.1.0.
-
-## BC BREAK: Lifecycle callback mapping on embedded classes is now explicitly forbidden
-
-Lifecycle callback mapping on embedded classes produced no effect, and is now
-explicitly forbidden to point out mistakes.
-
-## BC BREAK: The `NOTIFY` change tracking policy is removed
-
-You should use `DEFERRED_EXPLICIT` instead.
-
-## BC BREAK: `Mapping\Driver\XmlDriver::__construct()` third argument is now enabled by default
-
-The third argument to
-`Doctrine\ORM\Mapping\Driver\XmlDriver::__construct()` was introduced to
-let users opt-in to XML validation, that is now always enabled by default.
-
-As a consequence, the same goes for
-`Doctrine\ORM\Mapping\Driver\SimplifiedXmlDriver`, and for
-`Doctrine\ORM\ORMSetup::createXMLMetadataConfiguration()`.
-
-## BC BREAK: `Mapping\Driver\AttributeDriver::__construct()` second argument is now a no-op
-
-The second argument to
-`Doctrine\ORM\Mapping\Driver\AttributeDriver::__construct()` was introduced to
-let users opt-in to a new behavior, that is now always enforced, regardless of
-the value of that argument.
-
-## BC BREAK: `Query::setDQL()` and `Query::setFirstResult()` no longer accept `null`
-
-The `$dqlQuery` argument of `Doctrine\ORM\Query::setDQL()` must always be a
-string.
-
-The `$firstResult` argument of `Doctrine\ORM\Query::setFirstResult()` must
-always be an integer.
-
-## BC BREAK: `orm:schema-tool:update` option `--complete` is now a no-op
-
-`orm:schema-tool:update` now behaves as if `--complete` was provided,
-regardless of whether it is provided or not.
-
-## BC BREAK: Removed `Doctrine\ORM\Proxy\Proxy` interface.
-
-Use `Doctrine\Persistence\Proxy` instead to check whether proxies are initialized.
-
-## BC BREAK: Overriding fields or associations declared in other than mapped superclasses
-
-As stated in the documentation, fields and associations may only be overridden when being inherited
-from mapped superclasses. Overriding them for parent entity classes now throws a `MappingException`.
-
-## BC BREAK: Undeclared entity inheritance now throws a `MappingException`
-
-As soon as an entity class inherits from another entity class, inheritance has to
-be declared by adding the appropriate configuration for the root entity.
-
-## Removed `getEntityManager()` in `Doctrine\ORM\Event\OnClearEventArgs` and `Doctrine\ORM\Event\*FlushEventArgs`
-
-Use `getObjectManager()` instead.
-
-## BC BREAK: Removed `Doctrine\ORM\Mapping\ClassMetadataInfo` class
-
-Use `Doctrine\ORM\Mapping\ClassMetadata` instead.
-
-## BC BREAK: Removed `Doctrine\ORM\Event\LifecycleEventArgs` class.
-
-Use one of the dedicated event classes instead:
-
-* `Doctrine\ORM\Event\PrePersistEventArgs`
-* `Doctrine\ORM\Event\PreUpdateEventArgs`
-* `Doctrine\ORM\Event\PreRemoveEventArgs`
-* `Doctrine\ORM\Event\PostPersistEventArgs`
-* `Doctrine\ORM\Event\PostUpdateEventArgs`
-* `Doctrine\ORM\Event\PostRemoveEventArgs`
-* `Doctrine\ORM\Event\PostLoadEventArgs`
-
-## BC BREAK: Removed `AttributeDriver::$entityAnnotationClasses` and `AttributeDriver::getReader()`
-
-* If you need to change the behavior of `AttributeDriver::isTransient()`,
-  override that method instead.
-* The attribute reader is internal to the driver and should not be accessed from outside.
-
-## BC BREAK: Removed `Doctrine\ORM\Query\AST\InExpression`
-
-The AST parser will create a `InListExpression` or a `InSubselectExpression` when
-encountering an `IN ()` DQL expression instead of a generic `InExpression`.
-
-As a consequence, `SqlWalker::walkInExpression()` has been replaced by
-`SqlWalker::walkInListExpression()` and `SqlWalker::walkInSubselectExpression()`.
-
-## BC BREAK: Changed `EntityManagerInterface#refresh($entity)`, `EntityManagerDecorator#refresh($entity)` and `UnitOfWork#refresh($entity)` signatures
-
-The new signatures of these methods add an optional `LockMode|int|null $lockMode`
-param with default `null` value (no lock).
-
-## BC Break: Removed AnnotationDriver
-
-The annotation driver and anything related to annotation has been removed.
-Please migrate to another mapping driver.
-
-The `Doctrine\ORM\Mapping\Annotation` maker interface has been removed in favor of the new
-`Doctrine\ORM\Mapping\MappingAttribute` interface.
-
-## BC BREAK: Removed `EntityManager::create()`
-
-The constructor of `EntityManager` is now public and must be used instead of the `create()` method.
-However, the constructor expects a `Connection` while `create()` accepted an array with connection parameters.
-You can pass that array to DBAL's `Doctrine\DBAL\DriverManager::getConnection()` method to bootstrap the
-connection.
-
-## BC BREAK: Removed `QueryBuilder` methods and constants.
-
-The following `QueryBuilder` constants and methods have been removed:
-
-1. `SELECT`,
-2. `DELETE`,
-3. `UPDATE`,
-4. `STATE_DIRTY`,
-5. `STATE_CLEAN`,
-6. `getState()`,
-7. `getType()`.
-
-## BC BREAK: Omitting only the alias argument for `QueryBuilder::update` and `QueryBuilder::delete` is not supported anymore
-
-When building an UPDATE or DELETE query and when passing a class/type to the function, the alias argument must not be omitted.
-
-### Before
-
-```php
-$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);
-```
-
-## BC BREAK: Split output walkers and tree walkers
-
-`SqlWalker` and its child classes don't implement the `TreeWalker` interface
-anymore.
-
-The following methods have been removed from the `TreeWalker` interface and
-from the `TreeWalkerAdapter` and `TreeWalkerChain` classes:
-
-* `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:
-
-* The method `setQueryComponent()` is now protected.
-* The method `_getQueryComponents()` has been removed in favor of
-  `getQueryComponents()`.
-
-## BC BREAK: Removed identity columns emulation through sequences
-
-If the platform you are using does not support identity columns, you should
-switch to the `SEQUENCE` strategy.
-
-## BC BREAK: Made setters parameters mandatory
-
-The following methods require an argument when being called. Pass `null`
-instead of omitting the argument.
-
-* `Doctrine\ORM\Event\OnClassMetadataNotFoundEventArgs::setFoundMetadata()`
-* `Doctrine\ORM\AbstractQuery::setHydrationCacheProfile()`
-* `Doctrine\ORM\AbstractQuery::setResultCache()`
-* `Doctrine\ORM\AbstractQuery::setResultCacheProfile()`
-
-## BC BREAK: New argument to `NamingStrategy::joinColumnName()`
-
-### Before
-
-```php
-<?php
-class MyStrategy implements NamingStrategy
-{
-    /**
-     * @param string $propertyName A property name.
-     */
-    public function joinColumnName($propertyName): string
-    {
-        // …
-    }
-}
-```
-
-### After
-
-The `class-string` type for `$className` can be inherited from the signature of
-the interface.
-
-```php
-<?php
-class MyStrategy implements NamingStrategy
-{
-    /**
-     * {@inheritdoc}
-     */
-    public function joinColumnName(string $propertyName, string $className): string
-    {
-        // …
-    }
-}
-```
-
-## BC BREAK: Remove `StaticPHPDriver` and `DriverChain`
-
-Use `Doctrine\Persistence\Mapping\Driver\StaticPHPDriver` and
-`Doctrine\Persistence\Mapping\Driver\MappingDriverChain` from
-`doctrine/persistence` instead.
-
-## BC BREAK: `UnderscoreNamingStrategy` is number aware only
-
-The second argument to `UnderscoreNamingStrategy::__construct()` was dropped,
-the strategy can no longer be unaware of numbers.
-
-## BC BREAK: Remove `Doctrine\ORM\Tools\DisconnectedClassMetadataFactory`
-
-No replacement is provided.
-
-## BC BREAK: Remove support for `Type::canRequireSQLConversion()`
-
-This feature was deprecated in DBAL 3.3.0 and will be removed in DBAL 4.0.
-The value conversion methods are now called regardless of the type.
-
-The `MappingException::sqlConversionNotAllowedForIdentifiers()` method has been removed
-as no longer relevant.
-
-## BC Break: Removed the `doctrine` binary.
-
-The documentation explains how the console tools can be bootstrapped for
-standalone usage:
-
-https://www.doctrine-project.org/projects/doctrine-orm/en/stable/reference/tools.html
-
-The method `ConsoleRunner::printCliConfigTemplate()` has been removed as well
-because it was only useful in the context of the `doctrine` binary.
-
-## BC Break: Removed `EntityManagerHelper` and related logic
-
-All console commands require a `$entityManagerProvider` to be passed via the
-constructor. Commands won't try to get the entity manager from a previously
-registered `em` console helper.
-
-The following classes have been removed:
-
-* `Doctrine\ORM\Tools\Console\EntityManagerProvider\HelperSetManagerProvider`
-* `Doctrine\ORM\Tools\Console\Helper\EntityManagerHelper`
-
-The following breaking changes have been applied to `Doctrine\ORM\Tools\Console\ConsoleRunner`:
-
-* The method `createHelperSet()` has been removed.
-* The methods `run()` and `createApplication()` don't accept an instance of
-  `HelperSet` as first argument anymore.
-* The method `addCommands()` requires an instance of `EntityManagerProvider`
-  as second argument now.
-
-## BC Break: `Exception\ORMException` is no longer a class, but an interface
-
-All methods in `Doctrine\ORM\ORMException` have been extracted to dedicated exceptions.
-
- * `missingMappingDriverImpl()` => `Exception\MissingMappingDriverImplementation::create()`
- * `unrecognizedField()` => `Persisters\Exception\UnrecognizedField::byName()`
- * `unexpectedAssociationValue()` => `Exception\UnexpectedAssociationValue::create()`
- * `invalidOrientation()` => `Persisters\Exception\InvalidOrientation::fromClassNameAndField()`
- * `entityManagerClosed()` => `Exception\EntityManagerClosed::create()`
- * `invalidHydrationMode()` => `Exception\InvalidHydrationMode::fromMode()`
- * `mismatchedEventManager()` => `Exception\MismatchedEventManager::create()`
- * `findByRequiresParameter()` => `Repository\Exception\InvalidMagicMethodCall::onMissingParameter()`
- * `invalidMagicCall()` => `Repository\Exception\InvalidMagicMethodCall::becauseFieldNotFoundIn()`
- * `invalidFindByInverseAssociation()` => `Repository\Exception\InvalidFindByCall::fromInverseSideUsage()`
- * `invalidResultCacheDriver()` => `Cache\Exception\InvalidResultCacheDriver::create()`
- * `notSupported()` => `Exception\NotSupported::create()`
- * `queryCacheNotConfigured()` => `QueryCacheNotConfigured::create()`
- * `metadataCacheNotConfigured()` => `Cache\Exception\MetadataCacheNotConfigured::create()`
- * `queryCacheUsesNonPersistentCache()` => `Cache\Exception\QueryCacheUsesNonPersistentCache::fromDriver()`
- * `metadataCacheUsesNonPersistentCache()` => `Cache\Exception\MetadataCacheUsesNonPersistentCache::fromDriver()`
- * `proxyClassesAlwaysRegenerating()` => `Exception\ProxyClassesAlwaysRegenerating::create()`
- * `invalidEntityRepository()` => `Exception\InvalidEntityRepository::fromClassName()`
- * `missingIdentifierField()` => `Exception\MissingIdentifierField::fromFieldAndClass()`
- * `unrecognizedIdentifierFields()` => `Exception\UnrecognizedIdentifierFields::fromClassAndFieldNames()`
- * `cantUseInOperatorOnCompositeKeys()` => `Persisters\Exception\CantUseInOperatorOnCompositeKeys::create()`
-
-## BC Break: `CacheException` is no longer a class, but an interface
-
-All methods in `Doctrine\ORM\Cache\CacheException` have been extracted to dedicated exceptions.
-
- * `updateReadOnlyCollection()` => `Cache\Exception\CannotUpdateReadOnlyCollection::fromEntityAndField()`
- * `updateReadOnlyEntity()` => `Cache\Exception\CannotUpdateReadOnlyEntity::fromEntity()`
- * `nonCacheableEntity()` => `Cache\Exception\NonCacheableEntity::fromEntity()`
- * `nonCacheableEntityAssociation()` => `Cache\Exception\NonCacheableEntityAssociation::fromEntityAndField()`
-
-
-## BC Break: Missing type declaration added for identifier generators
-
-Although undocumented, it was possible to configure a custom repository
-class that implements `ObjectRepository` but does not extend the
-`EntityRepository` base class. Repository classes have to extend
-`EntityRepository` now.
-
-## BC BREAK: Removed support for entity namespace alias
-
-- `EntityManager::getRepository()` no longer accepts the entity namespace alias
-  notation.
-- `Configuration::addEntityNamespace()` and
-  `Configuration::getEntityNamespace()` have been removed.
-
-## BC BREAK: Remove helper methods from `AbstractCollectionPersister`
-
-The following protected methods of
-`Doctrine\ORM\Cache\Persister\Collection\AbstractCollectionPersister`
-have been removed.
-
-* `evictCollectionCache()`
-* `evictElementCache()`
-
-## BC BREAK: `Doctrine\ORM\Query\TreeWalkerChainIterator`
-
-This class has been removed without replacement.
-
-## BC BREAK: Remove quoting methods from `ClassMetadata`
-
-The following methods have been removed from the class metadata because
-quoting is handled by implementations of `Doctrine\ORM\Mapping\QuoteStrategy`:
-
-* `getQuotedIdentifierColumnNames()`
-* `getQuotedColumnName()`
-* `getQuotedTableName()`
-* `getQuotedJoinTableName()`
-
-## BC BREAK: Remove ability to merge detached entities
-
-Merge semantics was a poor fit for the PHP "share-nothing" architecture.
-In addition to that, merging caused multiple issues with data integrity
-in the managed entity graph, which was constantly spawning more edge-case
-bugs/scenarios.
-
-The method `UnitOfWork::merge()` has been removed. The method
-`EntityManager::merge()` will throw an exception on each call.
-
-## BC BREAK: Removed ability to partially flush/commit entity manager and unit of work
-
-The following methods don't accept a single entity or an array of entities anymore:
-
-* `Doctrine\ORM\EntityManager::flush()`
-* `Doctrine\ORM\Decorator\EntityManagerDecorator::flush()`
-* `Doctrine\ORM\UnitOfWork::commit()`
-
-The semantics of `flush()` and `commit()` will remain the same, but the change
-tracking will be performed on all entities managed by the unit of work, and not
-just on the provided entities, as the parameter is now completely ignored.
-
-## BC BREAK: Removed ability to partially clear entity manager and unit of work
-
-* Passing an argument other than `null` to `EntityManager::clear()` will raise
-  an exception.
-* The unit of work cannot be cleared partially anymore. Passing an argument to
-  `UnitOfWork::clear()` does not have any effect anymore; the unit of work is
-  cleared completely.
-* The method `EntityRepository::clear()` has been removed.
-* The methods `getEntityClass()` and `clearsAllEntities()` have been removed
-  from `OnClearEventArgs`.
-
-## BC BREAK: Remove support for Doctrine Cache
-
-The Doctrine Cache library is not supported anymore. The following methods
-have been removed from `Doctrine\ORM\Configuration`:
-
-* `getQueryCacheImpl()`
-* `setQueryCacheImpl()`
-* `getHydrationCacheImpl()`
-* `setHydrationCacheImpl()`
-* `getMetadataCacheImpl()`
-* `setMetadataCacheImpl()`
-
-The methods have been replaced by PSR-6 compatible counterparts
-(just strip the `Impl` suffix from the old name to get the new one).
-
-## BC BREAK: Remove `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.
-
-## BC BREAK: Remove `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 removed.
-
-The replacement is `Doctrine\ORM\ORMSetup` which accepts a PSR-6
-cache instead.
-
-## BC BREAK: Removed named queries
-
-All APIs related to named queries have been removed.
-
-## BC BREAK: Remove old cache accessors and mutators from query classes
-
-The following methods have been removed from `AbstractQuery`:
-
-* `setResultCacheDriver()`
-* `getResultCacheDriver()`
-* `useResultCache()`
-* `getResultCacheLifetime()`
-* `getResultCacheId()`
-
-The following methods have been removed from `Query`:
-
-* `setQueryCacheDriver()`
-* `getQueryCacheDriver()`
-
-## BC BREAK: Remove `Doctrine\ORM\Cache\MultiGetRegion`
-
-The interface has been merged into `Doctrine\ORM\Cache\Region`.
-
-## BC BREAK: Rename `AbstractIdGenerator::generate()` to `generateId()`
-
-* Implementations of `AbstractIdGenerator` have to implement the method
-  `generateId()`.
-* The method `generate()` has been removed from `AbstractIdGenerator`.
-
-## BC BREAK: Remove 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 removed:
-
-* `Configuration::ensureProductionSettings()`
-* the `orm:ensure-production-settings` console command
-
-## BC BREAK: 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 not supported anymore.
-
-* `DefaultCacheFactory`: The constructor expects a PSR-6 cache item pool as
-  second argument now.
-* `DefaultMultiGetRegion`: This class has been removed.
-* `DefaultRegion`:
-    * The constructor expects a PSR-6 cache item pool as second argument now.
-    * The protected `$cache` property is removed.
-    * The properties `$name` and `$lifetime` as well as the constant
-      `REGION_KEY_SEPARATOR` and the method `getCacheEntryKey()` are
-      `private` now.
-    * The method `getCache()` has been removed.
-
-
-## BC Break: Remove `Doctrine\ORM\Mapping\Driver\PHPDriver`
-
-Use `StaticPHPDriver` instead when you want to programmatically configure
-entity metadata.
-
-## BC BREAK: Remove `Doctrine\ORM\EntityManagerInterface#transactional()`
-
-This method has been replaced by `Doctrine\ORM\EntityManagerInterface#wrapInTransaction()`.
-
-## BC BREAK: Removed support for schema emulation.
-
-The ORM no longer attempts to emulate schemas on SQLite.
-
-## BC BREAK: Remove `Setup::registerAutoloadDirectory()`
-
-Use Composer's autoloader instead.
-
-## BC BREAK: Remove YAML mapping drivers.
-
-If your code relies on `YamlDriver` or `SimpleYamlDriver`, you **MUST** migrate to
-attribute, annotation or XML drivers instead.
-
-You can use the `orm:convert-mapping` command to convert your metadata mapping to XML
-_before_ upgrading to 3.0:
-
-```sh
-php doctrine orm:convert-mapping xml /path/to/mapping-path-converted-to-xml
-```
-
-## BC BREAK: Remove code generators and related console commands
-
-These console commands have been removed:
-
-* `orm:convert-d1-schema`
-* `orm:convert-mapping`
-* `orm:generate:entities`
-* `orm:generate-repositories`
-
-These classes have been deprecated:
-
-* `Doctrine\ORM\Tools\ConvertDoctrine1Schema`
-* `Doctrine\ORM\Tools\EntityGenerator`
-* `Doctrine\ORM\Tools\EntityRepositoryGenerator`
-
-The entire `Doctrine\ORM\Tools\Export` namespace has been removed as well.
-
-## BC BREAK: Removed `Doctrine\ORM\Version`
-
-Use Composer's runtime API if you _really_ need to check the version of the ORM package at runtime.
-
-## BC BREAK: EntityRepository::count() signature change
-
-The argument `$criteria` of `Doctrine\ORM\EntityRepository::count()` is now
-optional. Overrides in child classes should be made compatible.
-
-## BC BREAK: changes in exception hierarchy
-
-- `Doctrine\ORM\ORMException` has been removed
-- `Doctrine\ORM\Exception\ORMException` is now an interface
-
-## Variadic methods now use native variadics
-The following methods were using `func_get_args()` to simulate a variadic argument:
-- `Doctrine\ORM\Query\Expr#andX()`
-- `Doctrine\ORM\Query\Expr#orX()`
-- `Doctrine\ORM\QueryBuilder#select()`
-- `Doctrine\ORM\QueryBuilder#addSelect()`
-- `Doctrine\ORM\QueryBuilder#where()`
-- `Doctrine\ORM\QueryBuilder#andWhere()`
-- `Doctrine\ORM\QueryBuilder#orWhere()`
-- `Doctrine\ORM\QueryBuilder#groupBy()`
-- `Doctrine\ORM\QueryBuilder#andGroupBy()`
-- `Doctrine\ORM\QueryBuilder#having()`
-- `Doctrine\ORM\QueryBuilder#andHaving()`
-- `Doctrine\ORM\QueryBuilder#orHaving()`
-A variadic argument is now actually used in their signatures signature (`...$x`).
-Signatures of overridden methods should be changed accordingly
-
-## Minor BC BREAK: removed `Doctrine\ORM\EntityManagerInterface#copy()`
-
-Method `Doctrine\ORM\EntityManagerInterface#copy()` never got its implementation and is removed in 3.0.
-
-## BC BREAK: Removed classes related to UUID and TABLE generator strategies
-
-The following classes have been removed:
-- `Doctrine\ORM\Id\TableGenerator`
-- `Doctrine\ORM\Id\UuidGenerator`
-
-Using the `UUID` strategy for generating identifiers is not supported anymore.
-
-## BC BREAK: Removed `Query::iterate()`
-
-The deprecated method `Query::iterate()` has been removed along with the
-following classes and methods:
-
-- `AbstractHydrator::iterate()`
-- `AbstractHydrator::hydrateRow()`
-- `IterableResult`
-
-Use `toIterable()` instead.
+Use the `\Doctrine\ORM\Query::HINT_CUSTOM_OUTPUT_WALKER` query hint to set the output walker
+class instead of setting it through the `\Doctrine\ORM\Query\Parser::setCustomOutputTreeWalker()` method
+on the parser instance.

+Implementing the Notify ChangeTracking Policy
+=============================================
+
+.. sectionauthor:: Roman Borschel <roman@code-factory.org>
+
+The NOTIFY change-tracking policy is the most effective
+change-tracking policy provided by Doctrine but it requires some
+boilerplate code. This recipe will show you how this boilerplate
+code should look like. We will implement it on a
+`Layer Supertype <https://martinfowler.com/eaaCatalog/layerSupertype.html>`_
+for all our domain objects.
+
+.. note::
+
+    The notify change tracking policy is deprecated and will be removed in ORM 3.0.
+    (\ `Details <https://github.com/doctrine/orm/issues/8383>`_)
+
+Implementing NotifyPropertyChanged
+----------------------------------
+
+The NOTIFY policy is based on the assumption that the entities
+notify interested listeners of changes to their properties. For
+that purpose, a class that wants to use this policy needs to
+implement the ``NotifyPropertyChanged`` interface from the
+``Doctrine\Common`` namespace.
+
+.. code-block:: php
+
+    <?php
+    use Doctrine\Persistence\NotifyPropertyChanged;
+    use Doctrine\Persistence\PropertyChangedListener;
+
+    abstract class DomainObject implements NotifyPropertyChanged
+    {
+        private $listeners = array();
+
+        public function addPropertyChangedListener(PropertyChangedListener $listener) {
+            $this->listeners[] = $listener;
+        }
+
+        /** Notifies listeners of a change. */
+        protected function onPropertyChanged($propName, $oldValue, $newValue) {
+            if ($this->listeners) {
+                foreach ($this->listeners as $listener) {
+                    $listener->propertyChanged($this, $propName, $oldValue, $newValue);
+                }
+            }
+        }
+    }
+
+Then, in each property setter of concrete, derived domain classes,
+you need to invoke onPropertyChanged as follows to notify
+listeners:
+
+.. code-block:: php
+
+    <?php
+    // Mapping not shown, either in attributes, annotations, xml or yaml as usual
+    class MyEntity extends DomainObject
+    {
+        private $data;
+        // ... other fields as usual
+
+        public function setData($data) {
+            if ($data != $this->data) { // check: is it actually modified?
+                $this->onPropertyChanged('data', $this->data, $data);
+                $this->data = $data;
+            }
+        }
+    }
+
+The check whether the new value is different from the old one is
+not mandatory but recommended. That way you can avoid unnecessary
+updates and also have full control over when you consider a
+property changed.

+~~~~~~
+
+.. note::
+
+    The notify change tracking policy is deprecated and will be removed in ORM 3.0.
+    (\ `Details <https://github.com/doctrine/orm/issues/8383>`_)
+
+This policy is based on the assumption that the entities notify
+interested listeners of changes to their properties. For that
+purpose, a class that wants to use this policy needs to implement
+the ``NotifyPropertyChanged`` interface from the Doctrine
+namespace. As a guideline, such an implementation can look as
+follows:
+
+.. code-block:: php
+
+    <?php
+    use Doctrine\Persistence\NotifyPropertyChanged,
+        Doctrine\Persistence\PropertyChangedListener;
+
+    #[Entity]
+    #[ChangeTrackingPolicy('NOTIFY')]
+    class MyEntity implements NotifyPropertyChanged
+    {
+        // ...
+
+        private array $_listeners = array();
+
+        public function addPropertyChangedListener(PropertyChangedListener $listener): void
+        {
+            $this->_listeners[] = $listener;
+        }
+    }
+
+Then, in each property setter of this class or derived classes, you
+need to notify all the ``PropertyChangedListener`` instances. As an
+example we add a convenience method on ``MyEntity`` that shows this
+behaviour:
+
+.. code-block:: php
+
+    <?php
+    // ...
+
+    class MyEntity implements NotifyPropertyChanged
+    {
+        // ...
+
+        protected function _onPropertyChanged($propName, $oldValue, $newValue): void
+        {
+            if ($this->_listeners) {
+                foreach ($this->_listeners as $listener) {
+                    $listener->propertyChanged($this, $propName, $oldValue, $newValue);
+                }
+            }
+        }
+
+        public function setData($data): void
+        {
+            if ($data != $this->data) {
+                $this->_onPropertyChanged('data', $this->data, $data);
+                $this->data = $data;
+            }
+        }
+    }
+
+You have to invoke ``_onPropertyChanged`` inside every method that
+changes the persistent state of ``MyEntity``.
+
+The check whether the new value is different from the old one is
+not mandatory but recommended. That way you also have full control
+over when you consider a property changed.
+
+If your entity contains an embeddable, you will need to notify
+separately for each property in the embeddable when it changes
+for example:
+
+.. code-block:: php
+
+    <?php
+    // ...
+
+    class MyEntity implements NotifyPropertyChanged
+    {
+        public function setEmbeddable(MyValueObject $embeddable): void
+        {
+            if (!$embeddable->equals($this->embeddable)) {
+                // notice the entityField.embeddableField notation for referencing the property
+                $this->_onPropertyChanged('embeddable.prop1', $this->embeddable->getProp1(), $embeddable->getProp1());
+                $this->_onPropertyChanged('embeddable.prop2', $this->embeddable->getProp2(), $embeddable->getProp2());
+                $this->embeddable = $embeddable;
+            }
+        }
+    }
+
+This would update all the fields of the embeddable, you may wish to
+implement a diff method on your embedded object which returns only
+the changed fields.
+
+The negative point of this policy is obvious: You need implement an
+interface and write some plumbing code. But also note that we tried
+hard to keep this notification functionality abstract. Strictly
+speaking, it has nothing to do with the persistence layer and the
+Doctrine ORM or DBAL. You may find that property notification
+events come in handy in many other scenarios as well. As mentioned
+earlier, the ``Doctrine\Common`` namespace is not that evil and
+consists solely of very small classes and interfaces that have
+almost no external dependencies (none to the DBAL and none to the
+ORM) and that you can easily take with you should you want to swap
+out the persistence layer. This change tracking policy does not
+introduce a dependency on the Doctrine DBAL/ORM or the persistence
+layer.
+
+The positive point and main advantage of this policy is its
+effectiveness. It has the best performance characteristics of the 3
+policies with larger units of work and a flush() operation is very
+cheap when nothing has changed.

+Partial Object Syntax
+^^^^^^^^^^^^^^^^^^^^^
+
+By default when you run a DQL query in Doctrine and select only a
+subset of the fields for a given entity, you do not receive objects
+back. Instead, you receive only arrays as a flat rectangular result
+set, similar to how you would if you were just using SQL directly
+and joining some data.
+
+If you want to select partial objects you can use the ``partial``
+DQL keyword:
+
+.. code-block:: php
+
+    <?php
+    $query = $em->createQuery('SELECT partial u.{id, username} FROM CmsUser u');
+    $users = $query->getResult(); // array of partially loaded CmsUser objects
+
+You use the partial syntax when joining as well:

+

+    $query = $em->createQuery('SELECT partial u.{id, username}, partial a.{id, name} FROM CmsUser u JOIN u.articles a');

+Named Native Query
+------------------
+
+.. note::
+
+    Named Native Queries are deprecated as of version 2.9 and will be removed in ORM 3.0
+
+You can also map a native query using a named native query mapping.
+
+To achieve that, you must describe the SQL resultset structure
+using named native query (and sql resultset mappings if is a several resultset mappings).
+
+Like named query, a named native query can be defined at class level or in a XML or YAML file.

+A resultSetMapping parameter is defined in @NamedNativeQuery,

+    - The resultset mapping declares the entities retrieved by this native query.
+    - Each field of the entity is bound to a SQL alias (or column name).
+    - All fields of the entity including the ones of subclasses
+      and the foreign key columns of related entities have to be present in the SQL query.
+    - Field definitions are optional provided that they map to the same
+      column name as the one declared on the class property.
+    - ``__CLASS__`` is an alias for the mapped class
+
+
+In the above example,
+the ``fetchJoinedAddress`` named query use the joinMapping result set mapping.
+This mapping returns 2 entities, User and Address, each property is declared and associated to a column name,
+actually the column name retrieved by the query.
+
+Let's now see an implicit declaration of the property / column.

+Partial Objects
+===============
+
+
+.. note::
+
+    Creating Partial Objects through DQL is deprecated and
+    will be removed in the future, use data transfer object
+    support in DQL instead. (\ `Details
+    <https://github.com/doctrine/orm/issues/8471>`_)
+
+A partial object is an object whose state is not fully initialized
+after being reconstituted from the database and that is
+disconnected from the rest of its data. The following section will
+describe why partial objects are problematic and what the approach
+of Doctrine2 to this problem is.
+
+.. note::
+
+    The partial object problem in general does not apply to
+    methods or queries where you do not retrieve the query result as
+    objects. Examples are: ``Query#getArrayResult()``,
+    ``Query#getScalarResult()``, ``Query#getSingleScalarResult()``,
+    etc.
+
+.. warning::
+
+    Use of partial objects is tricky. Fields that are not retrieved
+    from the database will not be updated by the UnitOfWork even if they
+    get changed in your objects. You can only promote a partial object
+    to a fully-loaded object by calling ``EntityManager#refresh()``
+    or a DQL query with the refresh flag.
+
+
+What is the problem?
+--------------------
+
+In short, partial objects are problematic because they are usually
+objects with broken invariants. As such, code that uses these
+partial objects tends to be very fragile and either needs to "know"
+which fields or methods can be safely accessed or add checks around
+every field access or method invocation. The same holds true for
+the internals, i.e. the method implementations, of such objects.
+You usually simply assume the state you need in the method is
+available, after all you properly constructed this object before
+you pushed it into the database, right? These blind assumptions can
+quickly lead to null reference errors when working with such
+partial objects.
+
+It gets worse with the scenario of an optional association (0..1 to
+1). When the associated field is NULL, you don't know whether this
+object does not have an associated object or whether it was simply
+not loaded when the owning object was loaded from the database.
+
+These are reasons why many ORMs do not allow partial objects at all
+and instead you always have to load an object with all its fields
+(associations being proxied). One secure way to allow partial
+objects is if the programming language/platform allows the ORM tool
+to hook deeply into the object and instrument it in such a way that
+individual fields (not only associations) can be loaded lazily on
+first access. This is possible in Java, for example, through
+bytecode instrumentation. In PHP though this is not possible, so
+there is no way to have "secure" partial objects in an ORM with
+transparent persistence.
+
+Doctrine, by default, does not allow partial objects. That means,
+any query that only selects partial object data and wants to
+retrieve the result as objects (i.e. ``Query#getResult()``) will
+raise an exception telling you that partial objects are dangerous.
+If you want to force a query to return you partial objects,
+possibly as a performance tweak, you can use the ``partial``
+keyword as follows:
+
+.. code-block:: php
+
+    <?php
+    $q = $em->createQuery("select partial u.{id,name} from MyApp\Domain\User u");
+
+You can also get a partial reference instead of a proxy reference by
+calling:
+
+.. code-block:: php
+
+    <?php
+    $reference = $em->getPartialReference('MyApp\Domain\User', 1);
+
+Partial references are objects with only the identifiers set as they
+are passed to the second argument of the ``getPartialReference()`` method.
+All other fields are null.
+
+When should I force partial objects?
+------------------------------------
+
+Mainly for optimization purposes, but be careful of premature
+optimization as partial objects lead to potentially more fragile
+code.

 PHP Mapping

+Doctrine ORM also allows you to provide the ORM metadata in the form
+of plain PHP code using the ``ClassMetadata`` API. You can write
+the code in PHP files or inside of a static function named
+``loadMetadata($class)`` on the entity class itself.
+
+PHP Files
+---------
+
+.. note::
+
+   PHPDriver is deprecated and will be removed in 3.0, use StaticPHPDriver
+   instead.
+
+If you wish to write your mapping information inside PHP files that
+are named after the entity and included to populate the metadata
+for an entity you can do so by using the ``PHPDriver``:
+
+.. code-block:: php
+
+    <?php
+    $driver = new PHPDriver('/path/to/php/mapping/files');
+    $em->getConfiguration()->setMetadataDriverImpl($driver);
+
+Now imagine we had an entity named ``Entities\User`` and we wanted
+to write a mapping file for it using the above configured
+``PHPDriver`` instance:
+
+.. code-block:: php
+
+    <?php
+    namespace Entities;
+
+    class User
+    {
+        private $id;
+        private $username;
+    }
+
+To write the mapping information you just need to create a file
+named ``Entities.User.php`` inside of the
+``/path/to/php/mapping/files`` folder:
+
+.. code-block:: php
+
+    <?php
+    // /path/to/php/mapping/files/Entities.User.php
+
+    $metadata->mapField(array(
+       'id' => true,
+       'fieldName' => 'id',
+       'type' => 'integer'
+    ));
+
+    $metadata->mapField(array(
+       'fieldName' => 'username',
+       'type' => 'string',
+       'options' => array(
+           'fixed' => true,
+           'comment' => "User's login name"
+       )
+    ));
+
+    $metadata->mapField(array(
+       'fieldName' => 'login_count',
+       'type' => 'integer',
+       'nullable' => false,
+       'options' => array(
+           'unsigned' => true,
+           'default' => 0
+       )
+    ));
+
+Now we can easily retrieve the populated ``ClassMetadata`` instance
+where the ``PHPDriver`` includes the file and the
+``ClassMetadataFactory`` caches it for later retrieval:
+
+.. code-block:: php
+
+    <?php
+    $class = $em->getClassMetadata('Entities\User');
+    // or
+    $class = $em->getMetadataFactory()->getMetadataFor('Entities\User');
 
 Static Function
 ---------------
 
-In addition to other drivers using configuration languages you can also
-programatically specify your mapping information inside of a static function
-defined on the entity class itself.
-
-This is useful for cases where you want to keep your entity and mapping
-information together but don't want to use attributes. For this you just
-need to use the ``StaticPHPDriver``:

+
+It makes sense to generate the entity code if you are using entities as Data

+    code manually for inheritance to work!
+
+
+Convert Mapping Information
+---------------------------
+
+Convert mapping information between supported formats.
+
+This is an **execute one-time** command. It should not be necessary for
+you to call this method multiple times, especially when using the ``--from-database``
+flag.
+
+Converting an existing database schema into mapping files only solves about 70-80%
+of the necessary mapping information. Additionally the detection from an existing
+database cannot detect inverse associations, inheritance types,
+entities with foreign keys as primary keys and many of the
+semantical operations on associations such as cascade.
+
+.. note::
+
+    There is no need to convert YAML or XML mapping files to annotations
+    every time you make changes. All mapping drivers are first class citizens
+    in Doctrine 2 and can be used as runtime mapping for the ORM. See the
+    docs on XML and YAML Mapping for an example how to register this metadata
+    drivers as primary mapping source.
+
+To convert some mapping information between the various supported
+formats you can use the ``ClassMetadataExporter`` to get exporter
+instances for the different formats:
+
+.. code-block:: php
+
+    <?php
+    $cme = new \Doctrine\ORM\Tools\Export\ClassMetadataExporter();
+
+Once you have a instance you can use it to get an exporter. For
+example, the yml exporter:
+
+.. code-block:: php
+
+    <?php
+    $exporter = $cme->getExporter('yml', '/path/to/export/yml');
+
+Now you can export some ``ClassMetadata`` instances:
+
+.. code-block:: php
+
+    <?php
+    $classes = array(
+      $em->getClassMetadata('Entities\User'),
+      $em->getClassMetadata('Entities\Profile')
+    );
+    $exporter->setMetadata($classes);
+    $exporter->export();
+
+This functionality is also available from the command line to
+convert your loaded mapping information to another format. The
+``orm:convert-mapping`` command accepts two arguments, the type to
+convert to and the path to generate it:
+
+.. code-block:: php
+
+    $ php bin/doctrine orm:convert-mapping xml /path/to/mapping-path-converted-to-xml
+
+Reverse Engineering
+-------------------
+
+You can use the ``DatabaseDriver`` to reverse engineer a database to an
+array of ``ClassMetadata`` instances and generate YAML, XML, etc. from
+them.
+
+.. note::
+
+    Reverse Engineering is a **one-time** process that can get you started with a project.
+    Converting an existing database schema into mapping files only detects about 70-80%
+    of the necessary mapping information. Additionally the detection from an existing
+    database cannot detect inverse associations, inheritance types,
+    entities with foreign keys as primary keys and many of the
+    semantical operations on associations such as cascade.
+
+First you need to retrieve the metadata instances with the
+``DatabaseDriver``:
+
+.. code-block:: php
+
+    <?php
+    $em->getConfiguration()->setMetadataDriverImpl(
+        new \Doctrine\ORM\Mapping\Driver\DatabaseDriver(
+            $em->getConnection()->getSchemaManager()
+        )
+    );
+
+    $cmf = new \Doctrine\ORM\Tools\DisconnectedClassMetadataFactory();
+    $cmf->setEntityManager($em);
+    $metadata = $cmf->getAllMetadata();
+
+Now you can get an exporter instance and export the loaded metadata
+to yml:
+
+.. code-block:: php
+
+    <?php
+    $cme = new \Doctrine\ORM\Tools\Export\ClassMetadataExporter();
+    $exporter = $cme->getExporter('yml', '/path/to/export/yml');
+    $exporter->setMetadata($metadata);
+    $exporter->export();
+
+You can also reverse engineer a database using the
+``orm:convert-mapping`` command:
+
+.. code-block:: php
+
+    $ php bin/doctrine orm:convert-mapping --from-database yml /path/to/mapping-path-converted-to-yml
+
+.. note::
+
+    Reverse Engineering is not always working perfectly
+    depending on special cases. It will only detect Many-To-One
+    relations (even if they are One-To-One) and will try to create
+    entities from Many-To-Many tables. It also has problems with naming
+    of foreign keys that have multiple column names. Any Reverse
+    Engineered Database-Schema needs considerable manual work to become
+    a useful domain model.

+Merging entities
+----------------
+
+Merging entities refers to the merging of (usually detached)
+entities into the context of an EntityManager so that they become
+managed again. To merge the state of an entity into an
+EntityManager use the ``EntityManager#merge($entity)`` method. The
+state of the passed entity will be merged into a managed copy of
+this entity and this copy will subsequently be returned.
+
+Example:
+
+.. code-block:: php
+
+    <?php
+    $detachedEntity = unserialize($serializedEntity); // some detached entity
+    $entity = $em->merge($detachedEntity);
+    // $entity now refers to the fully managed copy returned by the merge operation.
+    // The EntityManager $em now manages the persistence of $entity as usual.
+
+
+The semantics of the merge operation, applied to an entity X, are
+as follows:
+
+
+-  If X is a detached entity, the state of X is copied onto a
+   pre-existing managed entity instance X' of the same identity.
+-  If X is a new entity instance, a new managed copy X' will be
+   created and the state of X is copied onto this managed instance.
+-  If X is a removed entity instance, an InvalidArgumentException
+   will be thrown.
+-  If X is a managed entity, it is ignored by the merge operation,
+   however, the merge operation is cascaded to entities referenced by
+   relationships from X if these relationships have been mapped with
+   the cascade element value MERGE or ALL (see ":ref:`transitive-persistence`").
+-  For all entities Y referenced by relationships from X having the
+   cascade element value MERGE or ALL, Y is merged recursively as Y'.
+   For all such Y referenced by X, X' is set to reference Y'. (Note
+   that if X is managed then X is the same object as X'.)
+-  If X is an entity merged to X', with a reference to another
+   entity Y, where cascade=MERGE or cascade=ALL is not specified, then
+   navigation of the same association from X' yields a reference to a
+   managed object Y' with the same persistent identity as Y.
+
+The ``merge`` operation will throw an ``OptimisticLockException``
+if the entity being merged uses optimistic locking through a
+version field and the versions of the entity being merged and the
+managed copy don't match. This usually means that the entity has
+been modified while being detached.
+
+The ``merge`` operation is usually not as frequently needed and
+used as ``persist`` and ``remove``. The most common scenario for
+the ``merge`` operation is to reattach entities to an EntityManager
+that come from some cache (and are therefore detached) and you want
+to modify and persist such an entity.
+
+.. warning::
+
+    If you need to perform multiple merges of entities that share certain subparts
+    of their object-graphs and cascade merge, then you have to call ``EntityManager#clear()`` between the
+    successive calls to ``EntityManager#merge()``. Otherwise you might end up with
+    multiple copies of the "same" object in the database, however with different ids.
+
+.. note::
+
+    If you load some detached entities from a cache and you do
+    not need to persist or delete them or otherwise make use of them
+    without the need for persistence services there is no need to use
