+Note about upgrading: Doctrine uses static and runtime mechanisms to raise
+awareness about deprecated code.
+
+- Use of `@deprecated` docblock that is detected by IDEs (like PHPStorm) or
+  Static Analysis tools (like Psalm, phpstan)
+- Use of our low-overhead runtime deprecation API, details:
+  https://github.com/doctrine/deprecations/
+
+# Upgrade to 3.x General Notes
+
+We recommend you upgrade to DBAL 3 first before upgrading to ORM 3. See
+the DBAL upgrade docs: https://github.com/doctrine/dbal/blob/3.10.x/UPGRADE.md
+
+Rather than doing several major upgrades at once, we recommend you do the following:
+
+- upgrade to DBAL 3
+- deploy and monitor
+- upgrade to ORM 3
+- deploy and monitor
+- upgrade to DBAL 4
+- deploy and monitor
+
+If you are using Symfony, the recommended minimal Doctrine Bundle version is 2.15
+to run with ORM 3.
+
+At this point, we recommend upgrading to PHP 8.4 first and then directly from
+ORM 2.19 to 3.5 and up so that you can skip the lazy ghost proxy generation
+and directly start using native lazy objects.
+
+# Upgrade to 3.6
+
+## Deprecate using string expression for default values in mappings
+
+Using a string expression for default values in field mappings is deprecated.
+Use `Doctrine\DBAL\Schema\DefaultExpression` instances instead.
+
+Here is how to address this deprecation when mapping entities using PHP attributes:

+     public int $id;

++    #[ORM\Column(options: ['default' => new CurrentTimestamp()], insertable: false, updatable: false)]
+     public DateTime $createdAt;
+
+-    #[ORM\Column(options: ['default' => 'CURRENT_TIME'], insertable: false, updatable: false)]
++    #[ORM\Column(options: ['default' => new CurrentTime()], insertable: false, updatable: false)]
