+# Upgrade to 2.12
+
+## Deprecated the `doctrine` binary.
+
+The documentation explains how the console tools can be bootstrapped for
+standalone usage.
+
+The method `ConsoleRunner::printCliConfigTemplate()` is deprecated because it
+was only useful in the context of the `doctrine` binary.
+
+## Deprecate omitting `$class` argument to `ORMInvalidArgumentException::invalidIdentifierBindingEntity()`
+
+To make it easier to identify understand the cause for that exception, it is
+deprecated to omit the class name when calling
+`ORMInvalidArgumentException::invalidIdentifierBindingEntity()`.
+
+## Deprecate `Doctrine\ORM\Tools\Console\Helper\EntityManagerHelper`
+
+Using a console helper to provide the ORM's console commands with one or
+multiple entity managers had been deprecated with 2.9 already. This leaves
+The `EntityManagerHelper` class with no purpose which is why it is now
+deprecated too. Applications that still rely on the `em` console helper, can
+easily recreate that class in their own codebase.
+
+## Deprecate custom repository classes that don't extend `EntityRepository`
+
+Although undocumented, it is currently possible to configure a custom repository
+class that implements `ObjectRepository` but does not extend the
+`EntityRepository` base class.
+
+This is now deprecated. Please extend `EntityRepository` instead.
+
+## Deprecated more APIs related to entity namespace aliases
+
+```diff
+-$config = $entityManager->getConfiguration();
+-$config->addEntityNamespace('CMS', 'My\App\Cms');
++use My\App\Cms\CmsUser;
+
+-$entityManager->getRepository('CMS:CmsUser');
++$entityManager->getRepository(CmsUser::class);
+```
+
+## Deprecate `AttributeDriver::getReader()` and `AnnotationDriver::getReader()`
+
+That method was inherited from the abstract `AnnotationDriver` class of
+`doctrine/persistence`, and does not seem to serve any purpose.
+
+## Un-deprecate `Doctrine\ORM\Proxy\Proxy`
+
+Because no forward-compatible new proxy solution had been implemented yet, the
+current proxy mechanism is not considered deprecated anymore for the time
+being. This applies to the following interfaces/classes:
+
+* `Doctrine\ORM\Proxy\Proxy`
+* `Doctrine\ORM\Proxy\ProxyFactory`
+
+These methods have been un-deprecated:
+
+* `Doctrine\ORM\Configuration::getAutoGenerateProxyClasses()`
+* `Doctrine\ORM\Configuration::getProxyDir()`
+* `Doctrine\ORM\Configuration::getProxyNamespace()`
+
+Note that the `Doctrine\ORM\Proxy\Autoloader` remains deprecated and will be removed in 3.0.
+
+## Deprecate helper methods from `AbstractCollectionPersister`
+
+The following protected methods of
+`Doctrine\ORM\Cache\Persister\Collection\AbstractCollectionPersister`
+are not in use anymore and will be removed.
+
+* `evictCollectionCache()`
+* `evictElementCache()`
+
+## Deprecate `Doctrine\ORM\Query\TreeWalkerChainIterator`
+
+This class won't have a replacement.
+
+## Deprecate `OnClearEventArgs::getEntityClass()` and `OnClearEventArgs::clearsAllEntities()`
+
+These methods will be removed in 3.0 along with the ability to partially clear
+the entity manager.
+
+## Deprecate `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.
+
+## Deprecate `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 deprecated.
+
+The replacement is `Doctrine\ORM\ORMSetup` which accepts a PSR-6
+cache instead.
+
+## Deprecate `Doctrine\ORM\Cache\MultiGetRegion`
+
+The interface will be merged with `Doctrine\ORM\Cache\Region` in 3.0.

+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

 Setting up the Commandline Tool
 -------------------------------
 
 Doctrine ships with a number of command line tools that are very helpful
-during development. You can call this command from the Composer binary
-directory:
-
-.. code-block:: sh
-
-    $ php vendor/bin/doctrine
-
-You need to register your applications EntityManager to the console tool
-to make use of the tasks by creating a ``cli-config.php`` file with the
-following content:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\Tools\Console\ConsoleRunner;
-
-    // replace with file to your own project bootstrap
-    require_once 'bootstrap.php';
-
-    // replace with mechanism to retrieve EntityManager in your app
-    $entityManager = GetEntityManager();
-
-    return ConsoleRunner::createHelperSet($entityManager);
+during development. In order to make use of them, create an executable PHP
+script in your project as described in the
+:doc:`tools chapter <../reference/tools>`.
