UPGRADE FROM 2.9 to 2.10

========================

Configuration
|
||
|
|
-------------
|
||
|
|
|
||
|
|
### Preparing for a new `report_fields_where_declared` mapping driver mode
|
||
|
|
|
||
|
|
Doctrine ORM 2.16+ makes a change to how the annotations and attribute mapping drivers report fields inherited from parent classes. For details, see https://github.com/doctrine/orm/pull/10455. It will trigger a deprecation notice unless the new mode is activated. In ORM 3.0, the new mode will be the only one.
|
||
|
|
|
||
|
|
The new mode ~does not~ should not make a difference for regular, valid use cases, but may lead to `MappingException`s for users with certain configurations that were not meant to be supported by the ORM in the first place. To avoid surprising users (even when their configuration is invalid) during a 2.16 _minor_ version upgrade, the transition to this new mode was implemented as an opt-in. This way, you can try and deal with the change any time you see fit.
|
||
|
|
|
||
|
|
In version 2.10+ of this bundle, a new configuration setting `report_fields_where_declared` was added at the entity manager configuration level. Set it to `true` to switch the mapping driver for the corresponding entity manager to the new mode. It is only relevant for mapping configurations using attributes or annotations.
|
||
|
|
|
||
|
|
Unless you set it to `true`, Doctrine ORM will emit deprecation messages mentioning this new setting.
|
||
|
|
|
||
|
|
### Preparing for the XSD validation for XML drivers
|
||
|
|
|
||
|
|
Doctrine ORM 2.14+ adds support for validating the XSD of XML mapping files. In ORM 3.0, this validation will be mandatory.
|
||
|
|
|
||
|
|
As the ecosystem is known to rely on custom elements in the XML mapping files that are forbidden when validating the XSD (for instance when using `gedmo/doctrine-extensions`), this validation is opt-in thanks to a `validate_xml_mapping` setting at the entity manager configuration level.
|
||
|
|
|
||
|
|
Unless you set it to `true`, Doctrine ORM will emit deprecation messages mentioning the XSD validation.
|
||
|

|
### Deprecations
|
||
|
|
|
||
|
|
- `Doctrine\Bundle\DoctrineBundle\EventSubscriber\EventSubscriberInterface` has been deprecated. Use the `#[AsDoctrineListener]` attribute instead.
