+## PSR-6-based second level cache
+
+The second level cache has been reworked to consume a PSR-6 cache. Using a

+## Deprecated: `Doctrine\ORM\Mapping\Driver\PHPDriver`
+
+Use `StaticPHPDriver` instead when you want to programmatically configure

+
+You can convert mappings with the `orm:convert-mapping` command or more simply

+Use Composer's autoloader instead.

+## Deprecated: `AbstractHydrator::hydrateRow()`
+
+Following the deprecation of the method `AbstractHydrator::iterate()`, the
+method `hydrateRow()` has been deprecated as well.
+
+## Deprecate cache settings inspection
+
+Doctrine does not provide its own cache implementation anymore and relies on
+the PSR-6 standard instead. As a consequence, we cannot determine anymore
+whether a given cache adapter is suitable for a production environment.
+Because of that, functionality that aims to do so has been deprecated:

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

+        {
+            // Always initializing the proxy before use
+            if ($this->parent instanceof Proxy) {

+            }
+
+            // Accessing the `$this->parent->name` property without loading the proxy first
+            // may throw error in case the Proxy has not been initialized yet.

 PHP Types Mapping
 _________________
 
-Since version 2.9 Doctrine can determine usable defaults from property types
-on entity classes. When property type is nullable this has no effect on
-``nullable`` Column attribute at the moment for backwards compatibility
-reasons.
+.. versionadded:: 2.9
 
-Additionally, Doctrine will map PHP types to ``type`` attribute as follows:
+The column types can be inferred automatically from PHP's property types.
+However, when the property type is nullable this has no effect on the ``nullable`` Column attribute.
 
-- ``DateInterval``: ``dateinterval``
-- ``DateTime``: ``datetime``
-- ``DateTimeImmutable``: ``datetime_immutable``
-- ``array``: ``json``
-- ``bool``: ``boolean``
-- ``float``: ``float``
-- ``int``: ``integer``
-- ``string`` or any other type: ``string``
+These are the "automatic" mapping rules:
