UPGRADE-7.3.md

UPGRADE FROM 7.2 to 7.3

Symfony 7.3 is a minor release. According to the Symfony release process, there should be no significant backward compatibility breaks. Minor backward compatibility breaks are prefixed in this document with [BC BREAK], make sure your code is compatible with these entries before upgrading. Read more about this in the Symfony documentation.

If you're upgrading from a version below 7.1, follow the 7.2 upgrade guide first.

Console

• Omitting parameter types in callables configured via Command::setCode method is deprecated

  Before

  $command->setCode(function ($input, $output) {
      // ...
  });

  After

  use Symfony\Component\Console\Input\InputInterface;
  use Symfony\Component\Console\Output\OutputInterface;
  
  $command->setCode(function (InputInterface $input, OutputInterface $output) {
      // ...
  });

• Deprecate methods Command::getDefaultName() and Command::getDefaultDescription() in favor of the #[AsCommand] attribute

FrameworkBundle

• Not setting the framework.property_info.with_constructor_extractor option explicitly is deprecated because its default value will change in version 8.0
• Deprecate the --show-arguments option of the container:debug command, as arguments are now always shown

Serializer

• Deprecate the CompiledClassMetadataFactory and CompiledClassMetadataCacheWarmer classes

Validator

• Deprecate defining custom constraints not supporting named arguments

  Before:

  use Symfony\Component\Validator\Constraint;
  
  class CustomConstraint extends Constraint
  {
      public function __construct(array $options)
      {
          // ...
      }
  }

  After:

  use Symfony\Component\Validator\Attribute\HasNamedArguments;
  use Symfony\Component\Validator\Constraint;
  
  class CustomConstraint extends Constraint
  {
      #[HasNamedArguments]
      public function __construct($option1, $option2, $groups, $payload)
      {
          // ...
      }
  }

• Deprecate passing an array of options to the constructors of the constraint classes, pass each option as a dedicated argument instead

  Before:

  new NotNull([
      'groups' => ['foo', 'bar'],
      'message' => 'a custom constraint violation message',
  ])

  After:

  new NotNull(
      groups: ['foo', 'bar'],
      message: 'a custom constraint violation message',
  )

TypeInfo

• Deprecate constructing a CollectionType instance as a list that is not an array
• Deprecate the third $asList argument of TypeFactoryTrait::iterable(), use TypeFactoryTrait::list() instead

VarDumper

• Deprecate ResourceCaster::castCurl(), ResourceCaster::castGd() and ResourceCaster::castOpensslX509()
• Mark all casters as @internal
