+## 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
+-----------------------------------------------------------------------------
+
+To safely access private property of different instance of the same class, make sure to initialise
+the proxy before use manually as follows:
+
+.. code-block:: php
+
+    <?php
+
+    use Doctrine\Common\Proxy\Proxy;
+    use Doctrine\ORM\Mapping as ORM;
+
+    /**

+     */
+    class Entity
+    {
+        // ...
+
+        /**
+         * @ORM\ManyToOne(targetEntity="Entity")
+         * @ORM\JoinColumn(nullable=false)
+         */
+        private self $parent;
+
+        /**
+         * @ORM\Column(type="string", nullable=false)
+         */
+        private string $name;
+
+        // ...
+
+        public function doSomethingWithParent()
+        {
+            // Always initializing the proxy before use
+            if ($this->parent instanceof Proxy) {
+                $this->parent->__load();
+            }
+
+            // Accessing the `$this->parent->name` property without loading the proxy first
+            // may throw error in case the Proxy has not been initialized yet.
+            $this->parent->name;
+        }
+
+        public function doSomethingWithAnotherInstance(self $instance)
+        {
+            // Always initializing the proxy before use
+            if ($instance instanceof Proxy) {
+                $instance->__load();
+            }

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