+# Upgrade to 3.3
+
+## Deprecate `DatabaseDriver`
+
+The class `Doctrine\ORM\Mapping\Driver\DatabaseDriver` is deprecated without replacement.
+
+# Upgrade to 3.2
+
+## Deprecate the `NotSupported` exception
+
+The class `Doctrine\ORM\Exception\NotSupported` is deprecated without replacement.
+
+## Deprecate remaining `Serializable` implementation
+
+Relying on `SequenceGenerator` implementing the `Serializable` is deprecated
+because that interface won't be implemented in ORM 4 anymore.
+
+The following methods are deprecated:
+
+* `SequenceGenerator::serialize()`
+* `SequenceGenerator::unserialize()`
+
+## `orm:schema-tool:update` option `--complete` is deprecated
+
+That option behaves as a no-op, and is deprecated. It will be removed in 4.0.
+
+## Deprecate properties `$indexes` and `$uniqueConstraints` of `Doctrine\ORM\Mapping\Table`
+
+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
+
+WARNING: This was relaxed in ORM 3.2 when partial was re-allowed for array-hydration.
+
+- The `PARTIAL` keyword in DQL no longer exists (reintroduced in ORM 3.2)
+- `Doctrine\ORM\Query\AST\PartialObjectExpression` is removed. (reintroduced in ORM 3.2)
+- `Doctrine\ORM\Query\SqlWalker::HINT_PARTIAL` (reintroduced in ORM 3.2) 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.
+
+# Upgrade to 2.20
+
+## Add `Doctrine\ORM\Query\OutputWalker` interface, deprecate `Doctrine\ORM\Query\SqlWalker::getExecutor()`
+
+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.
+
+## Explictly forbid property hooks
+
+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.
+
+Progress on this is tracked at https://github.com/doctrine/orm/issues/11624 .
+
+## PARTIAL DQL syntax is undeprecated 
+
+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.
+
+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 `\Doctrine\ORM\Query\Parser::setCustomOutputTreeWalker()`
+
+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.
+
+# Upgrade to 2.19
+
+## Deprecate calling `ClassMetadata::getAssociationMappedByTargetField()` with the owning side of an association
+
+Calling
+`Doctrine\ORM\Mapping\ClassMetadata::getAssociationMappedByTargetField()` with
+the owning side of an association returns `null`, which is 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.
+
+## Deprecate `Doctrine\ORM\Query\Lexer::T_*` constants
+
+Use `Doctrine\ORM\Query\TokenType::T_*` instead.
+
 # Upgrade to 2.17
 
 ## Deprecate annotations classes for named queries

-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.

-As an example, the Doctrine Mapping Type ``string`` defines the

-depending on the RDBMS brand). Here is a quick overview of the
-built-in mapping types:
-
--  ``string``: Type that maps a SQL VARCHAR to a PHP string.
--  ``integer``: Type that maps a SQL INT to a PHP integer.
--  ``smallint``: Type that maps a database SMALLINT to a PHP
-   integer.
--  ``bigint``: Type that maps a database BIGINT to a PHP string.
--  ``boolean``: Type that maps a SQL boolean or equivalent (TINYINT) to a PHP boolean.
--  ``decimal``: Type that maps a SQL DECIMAL to a PHP string.
--  ``date``: Type that maps a SQL DATETIME to a PHP DateTime
-   object.
--  ``time``: Type that maps a SQL TIME to a PHP DateTime object.
--  ``datetime``: Type that maps a SQL DATETIME/TIMESTAMP to a PHP
-   DateTime object.
--  ``datetimetz``: Type that maps a SQL DATETIME/TIMESTAMP to a PHP
-   DateTime object with timezone.
--  ``text``: Type that maps a SQL CLOB to a PHP string.
--  ``object``: Type that maps a SQL CLOB to a PHP object using
-   ``serialize()`` and ``unserialize()``
--  ``array``: Type that maps a SQL CLOB to a PHP array using
-   ``serialize()`` and ``unserialize()``
--  ``simple_array``: Type that maps a SQL CLOB to a PHP array using
-   ``implode()`` and ``explode()``, with a comma as delimiter. *IMPORTANT*
-   Only use this type if you are sure that your values cannot contain a ",".
--  ``json_array``: Type that maps a SQL CLOB to a PHP array using
-   ``json_encode()`` and ``json_decode()``
--  ``float``: Type that maps a SQL Float (Double Precision) to a
-   PHP double. *IMPORTANT*: Works only with locale settings that use
-   decimal points as separator.
--  ``guid``: Type that maps a database GUID/UUID to a PHP string. Defaults to
-   varchar but uses a specific type if the platform supports it.
--  ``blob``: Type that maps a SQL BLOB to a PHP resource stream

-.. 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.

+
+Note that you can only pass scalar expressions or other Data Transfer Objects to the constructor.
+
+If you use your data transfer objects for multiple queries, and you would rather not have to

+

+    <?php

+            public AddressDTO|null $address = null,
+        ) {
+        }
+    }
+
+You can specify arbitrary arguments in an arbitrary order by using the named argument syntax, and the ORM will try to match argument names with the selected column names.
+The syntax relies on the NAMED keyword, like so:
+
+.. code-block:: php
+
+    <?php
+    $query = $em->createQuery('SELECT NEW NAMED CustomerDTO(a.city, c.name) FROM Customer c JOIN c.address a');
+    $users = $query->getResult(); // array of CustomerDTO
+
+    // CustomerDTO => {name : 'SMITH', email: null, city: 'London', value: null}
+
+ORM will also give precedence to column aliases over column names :
+
+.. code-block:: php
+
+    <?php
+    $query = $em->createQuery('SELECT NEW NAMED CustomerDTO(c.name, CONCAT(a.city, ' ' , a.zip) AS value) FROM Customer c JOIN c.address a');
+    $users = $query->getResult(); // array of CustomerDTO
+
+    // CustomerDTO => {name : 'DOE', email: null, city: null, value: 'New York 10011'}
+
+To define a custom name for a DTO constructor argument, you can either alias the column with the ``AS`` keyword.
+
+The ``NAMED`` keyword must precede all DTO you want to instantiate :
+
+.. code-block:: php
+
+    <?php
+    $query = $em->createQuery('SELECT NEW NAMED CustomerDTO(c.name, NEW NAMED AddressDTO(a.street, a.city, a.zip) AS address) FROM Customer c JOIN c.address a');
+    $users = $query->getResult(); // array of CustomerDTO
+
+    // CustomerDTO => {name : 'DOE', email: null, city: null, value: 'New York 10011'}
+
+If two arguments have the same name, a ``DuplicateFieldException`` is thrown.
+If a field cannot be matched with a property name, a ``NoMatchingPropertyException`` is thrown. This typically happens when using functions without aliasing them.

-Using this method you can directly supply the hydration mode as the

+        {
+            return $this->_stmt->fetchAllAssociative();
+        }
+    }
+
+Next you just need to add the class to the ORM configuration:
+
+.. code-block:: php
+
+    <?php
+    $em->getConfiguration()->addCustomHydrationMode('CustomHydrator', 'MyProject\Hydrators\CustomHydrator');
+
+Now the hydrator is ready to be used in your queries:

-- If an object is already in memory from a previous query of any kind, then
-  then the previous object is used, even if the database may contain more
-  recent data. Data from the database is discarded. This even happens if the
-  previous object is still an unloaded proxy.
-
-This list might be incomplete.
-
-Array Hydration
-^^^^^^^^^^^^^^^
-
-You can run the same query with array hydration and the result set
-is hydrated into an array that represents the object graph:
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery('SELECT u FROM CmsUser u');
-    $users = $query->getResult(Query::HYDRATE_ARRAY);
-
-You can use the ``getArrayResult()`` shortcut as well:
-
-.. code-block:: php
-
-    <?php
-    $users = $query->getArrayResult();
-
-Scalar Hydration
-^^^^^^^^^^^^^^^^
-
-If you want to return a flat rectangular result set instead of an
-object graph you can use scalar hydration:
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery('SELECT u FROM CmsUser u');
-    $users = $query->getResult(Query::HYDRATE_SCALAR);
-    echo $users[0]['u_id'];
-
-The following assumptions are made about selected fields using
-Scalar Hydration:
-
-
-1. Fields from classes are prefixed by the DQL alias in the result.
-   A query of the kind 'SELECT u.name ..' returns a key 'u_name' in
-   the result rows.
-
-Single Scalar Hydration
-^^^^^^^^^^^^^^^^^^^^^^^
-
-If you have a query which returns just a single scalar value you can use
-single scalar hydration:
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery('SELECT COUNT(a.id) FROM CmsUser u LEFT JOIN u.articles a WHERE u.username = ?1 GROUP BY u.id');
-    $query->setParameter(1, 'jwage');
-    $numArticles = $query->getResult(Query::HYDRATE_SINGLE_SCALAR);
-
-You can use the ``getSingleScalarResult()`` shortcut as well:
-
-.. code-block:: php
-
-    <?php
-    $numArticles = $query->getSingleScalarResult();
-
-Scalar Column Hydration
-^^^^^^^^^^^^^^^^^^^^^^^
-
-If you have a query which returns a one-dimensional array of scalar values
-you can use scalar column hydration:
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery('SELECT a.id FROM CmsUser u');
-    $ids = $query->getResult(Query::HYDRATE_SCALAR_COLUMN);
-
-You can use the ``getSingleColumnResult()`` shortcut as well:
-
-.. code-block:: php
-
-    <?php
-    $ids = $query->getSingleColumnResult();
-
-Custom Hydration Modes
-^^^^^^^^^^^^^^^^^^^^^^
-
-You can easily add your own custom hydration modes by first
-creating a class which extends ``AbstractHydrator``:
-
-.. code-block:: php
-
-    <?php
-    namespace MyProject\Hydrators;
-
-    use Doctrine\ORM\Internal\Hydration\AbstractHydrator;
-
-    class CustomHydrator extends AbstractHydrator
-    {
-        protected function _hydrateAll()
-        {
-            return $this->_stmt->fetchAllAssociative();
-        }
-    }
-
-Next you just need to add the class to the ORM configuration:
-
-.. code-block:: php
-
-    <?php
-    $em->getConfiguration()->addCustomHydrationMode('CustomHydrator', 'MyProject\Hydrators\CustomHydrator');
-
-Now the hydrator is ready to be used in your queries:
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery('SELECT u FROM CmsUser u');
-    $results = $query->getResult('CustomHydrator');
-

-Things to note:
-    - 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.

-In this example, we only describe the entity member of the result set mapping.
-The property / column mappings is done using the entity mapping values.
-In this case the model property is bound to the model_txt column.
-If the association to a related entity involve a composite primary key,
-a @FieldResult element should be used for each foreign key column.
-The @FieldResult name is composed of the property name for the relationship,
-followed by a dot ("."), followed by the name or the field or property of the primary key.

+Partial Hydration
+=================

 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');

+PHP code using the ``ClassMetadata`` API. You can write the code in inside of a
+static function named ``loadMetadata($class)`` on the entity class itself.
 
 Static Function
 ---------------
 
-In addition to the PHP files you can also 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 or
-annotations. For this you just need to use the ``StaticPHPDriver``:

-
-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.
-

-    Reverse Engineering is a **one-time** process that can get you started with a project.

-    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
-    ``merge``. I.e. you can simply pass detached objects from a cache
