Values tagged with the non-specific tag must not be transformed in an integer, this tag means that they must not be evaluated (see [the spec](http://www.yaml.org/spec/1.2/spec.html#tag/non-specific/)).

I applied this change in https://github.com/symfony/symfony/pull/22762 to comply with the spec.

Raw Blame History

UPGRADE FROM 3.3 to 3.4

DependencyInjection

  • Top-level anonymous services in XML are deprecated and will throw an exception in Symfony 4.0.

Finder

  • The Symfony\Component\Finder\Iterator\FilterIterator class has been deprecated and will be removed in 4.0 as it used to fix a bug which existed before version 5.5.23/5.6.7.

FrameworkBundle

  • The doctrine/cache dependency has been removed; require it via composer require doctrine/cache if you are using Doctrine cache in your project.

  • The validator.mapping.cache.doctrine.apc service has been deprecated.

  • The symfony/stopwatch dependency has been removed, require it via composer require symfony/stopwatch in your dev environment.

  • Using the KERNEL_DIR environment variable or the automatic guessing based on the phpunit.xml / phpunit.xml.dist file location is deprecated since 3.4. Set the KERNEL_CLASS environment variable to the fully-qualified class name of your Kernel instead. Not setting the KERNEL_CLASS environment variable will throw an exception on 4.0 unless you override the KernelTestCase::createKernel() or KernelTestCase::getKernelClass() method.

  • The KernelTestCase::getPhpUnitXmlDir() and KernelTestCase::getPhpUnitCliConfigArgument() methods are deprecated since 3.4 and will be removed in 4.0.

  • The --no-prefix option of the translation:update command is deprecated and will be removed in 4.0. Use the --prefix option with an empty string as value instead (e.g. --prefix="")

Process

  • The Symfony\Component\Process\ProcessBuilder class has been deprecated, use the Symfony\Component\Process\Process class directly instead.

SecurityBundle

  • FirewallContext::getListeners() now returns \Traversable|array

Validator

  • Not setting the strict option of the Choice constraint to true is deprecated and will throw an exception in Symfony 4.0.

Yaml

  • Using the non-specific tag ! is deprecated and will have a different behavior in 4.0. Use a plain integer or !!float instead.
