+# 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.

+The ``type`` option used in the ``@Column`` accepts any of the

+or :doc:`your own custom mapping types

 the conversion between PHP and SQL types, independent from the database vendor
-you are using. All Mapping Types that ship with Doctrine are fully portable

-As an example, the Doctrine Mapping Type ``string`` defines the
-mapping from a PHP string to a SQL VARCHAR (or VARCHAR2 etc.
-depending on the RDBMS brand). Here is a quick overview of the
-built-in mapping types:
-

+Query Result Formats (Hydration Modes)

-The format in which the result of a DQL SELECT query is returned

-mode specifies a particular way in which a SQL result set is
-transformed. Each hydration mode has its own dedicated method on

+The way in which the SQL result set of a DQL SELECT query is transformed

+``getResult()``
+^^^^^^^^^^^^^^^
 
--  ``Query#getResult()``: Retrieves a collection of objects. The
-   result is either a plain collection of objects (pure) or an array
-   where the objects are nested in the result rows (mixed).
--  ``Query#getSingleResult()``: Retrieves a single object. If the
-   result contains more than one object, an ``NonUniqueResultException``
-   is thrown. If the result contains no objects, an ``NoResultException``
-   is thrown. The pure/mixed distinction does not apply.
--  ``Query#getOneOrNullResult()``: Retrieve a single object. If the
-   result contains more than one object, a ``NonUniqueResultException``
-   is thrown. If no object is found null will be returned.
--  ``Query#getArrayResult()``: Retrieves an array graph (a nested
-   array) that is largely interchangeable with the object graph
-   generated by ``Query#getResult()`` for read-only purposes.
+Retrieves a collection of objects. The result is either a plain collection of objects (pure) or an array
+where the objects are nested in the result rows (mixed):
 
-    .. note::
+.. code-block:: php

-        graph in certain scenarios due to the difference of the identity
-        semantics between arrays and objects.

+    use Doctrine\ORM\AbstractQuery;
 
+    $query = $em->createQuery('SELECT u FROM User u');
+    $users = $query->getResult();
+    // same as:
+    $users = $query->getResult(AbstractQuery::HYDRATE_OBJECT);
 
+- Objects fetched in a FROM clause are returned as a Set, that means every
+  object is only ever included in the resulting array once. This is the case
+  even when using JOIN or GROUP BY in ways that return the same row for an
+  object multiple times. If the hydrator sees the same object multiple times,
+  then it makes sure it is only returned once.
 
--  ``Query#getScalarResult()``: Retrieves a flat/rectangular result
-   set of scalar values that can contain duplicate data. The
-   pure/mixed distinction does not apply.
--  ``Query#getSingleScalarResult()``: Retrieves a single scalar
-   value from the result returned by the dbms. If the result contains
-   more than a single scalar value, an exception is thrown. The
-   pure/mixed distinction does not apply.
+- 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. This even happens if the previous object is still an unloaded proxy.
 
-Instead of using these methods, you can alternatively use the
-general-purpose method
-``Query#execute(array $params = [], $hydrationMode = Query::HYDRATE_OBJECT)``.
-Using this method you can directly supply the hydration mode as the
-second parameter via one of the Query constants. In fact, the
-methods mentioned earlier are just convenient shortcuts for the
-execute method. For example, the method ``Query#getResult()``
-internally invokes execute, passing in ``Query::HYDRATE_OBJECT`` as
-the hydration mode.

+            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:

-Hydration Modes
-~~~~~~~~~~~~~~~
-
-Each of the Hydration Modes makes assumptions about how the result

--  ``Query::HYDRATE_SCALAR``
--  ``Query::HYDRATE_SINGLE_SCALAR``
--  ``Query::HYDRATE_SCALAR_COLUMN``

-Object Hydration
-^^^^^^^^^^^^^^^^
-
-Object hydration hydrates the result set into the object graph:
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery('SELECT u FROM CmsUser u');
-    $users = $query->getResult(Query::HYDRATE_OBJECT);
-
-Sometimes the behavior in the object hydrator can be confusing, which is
-why we are listing as many of the assumptions here for reference:
-
-- Objects fetched in a FROM clause are returned as a Set, that means every
-  object is only ever included in the resulting array once. This is the case
-  even when using JOIN or GROUP BY in ways that return the same row for an
-  object multiple times. If the hydrator sees the same object multiple times,
-  then it makes sure it is only returned once.
-
-- 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:
