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 2.0

BC breaking changes

Native parameter types were added. Native return types will be added in 3.0.x As a consequence, some signatures were changed and will have to be adjusted in sub-classes.

Note that in order to keep compatibility with both 1.x and 2.x versions, extending code would have to omit the added parameter types. This would only work in PHP 7.2+ which is the first version featuring parameter widening. It is also recommended to add return types according to the tables below

You can find a list of major changes to public API below.
