Routing
-------

 * Deprecated creating instances of the `Route` annotation class by passing an array of parameters, use named arguments instead

Security
--------

 * [BC BREAK] Remove method `checkIfCompletelyResolved()` from `PassportInterface`, checking that passport badges are
   resolved is up to `AuthenticatorManager`
 * Deprecate class `User`, use `InMemoryUser` or your own implementation instead.
   If you are using the `isAccountNonLocked()`, `isAccountNonExpired()` or `isCredentialsNonExpired()` method, consider re-implementing
   them in your own user class, as they are not part of the `InMemoryUser` API
 * Deprecate class `UserChecker`, use `InMemoryUserChecker` or your own implementation instead
 * [BC break] Remove support for passing a `UserInterface` implementation to `Passport`, use the `UserBadge` instead.
 * Deprecate `UserInterface::getPassword()`
   If your `getPassword()` method does not return `null` (i.e. you are using password-based authentication),
   you should implement `PasswordAuthenticatedUserInterface`.

   Before:
   ```php
   use Symfony\Component\Security\Core\User\UserInterface;

   class User implements UserInterface
   {
       // ...

       public function getPassword()
       {
           return $this->password;
       }
   }
   ```

   After:
   ```php
   use Symfony\Component\Security\Core\User\UserInterface;
   use Symfony\Component\Security\Core\User\PasswordAuthenticatedUserInterface;

   class User implements UserInterface, PasswordAuthenticatedUserInterface
   {
       // ...

       public function getPassword(): ?string
       {
           return $this->password;
       }
   }
   ```

 * Deprecate `UserInterface::getSalt()`
   If your `getSalt()` method does not return `null` (i.e. you are using password-based authentication with an old password hash algorithm that requires user-provided salts),
   implement `LegacyPasswordAuthenticatedUserInterface`.

   Before:
   ```php
   use Symfony\Component\Security\Core\User\UserInterface;

   class User implements UserInterface
   {
       // ...

       public function getPassword()
       {
           return $this->password;
       }

       public function getSalt()
       {
           return $this->salt;
       }
   }
   ```

   After:
   ```php
   use Symfony\Component\Security\Core\User\UserInterface;
   use Symfony\Component\Security\Core\User\LegacyPasswordAuthenticatedUserInterface;

   class User implements UserInterface, LegacyPasswordAuthenticatedUserInterface
   {
       // ...

       public function getPassword(): ?string
       {
           return $this->password;
       }

       public function getSalt(): ?string
       {
           return $this->salt;
       }
   }
   ```

 * Deprecate calling `PasswordUpgraderInterface::upgradePassword()` with a `UserInterface` instance that does not implement `PasswordAuthenticatedUserInterface`
 * Deprecate calling methods `hashPassword()`, `isPasswordValid()` and `needsRehash()` on `UserPasswordHasherInterface` with a `UserInterface` instance that does not implement `PasswordAuthenticatedUserInterface`
 * Deprecate all classes in the `Core\Encoder\`  sub-namespace, use the `PasswordHasher` component instead
 * Deprecated voters that do not return a valid decision when calling the `vote` method

SecurityBundle
--------------

 * [BC break] Add `login_throttling.lock_factory` setting defaulting to `null`. Set this option
   to `lock.factory` if you need precise login rate limiting with synchronous requests.
 * Deprecate `UserPasswordEncoderCommand` class and the corresponding `user:encode-password` command,
   use `UserPasswordHashCommand` and `user:hash-password` instead
 * Deprecate the `security.encoder_factory.generic` service, the `security.encoder_factory` and `Symfony\Component\Security\Core\Encoder\EncoderFactoryInterface` aliases,
   use `security.password_hasher_factory` and `Symfony\Component\PasswordHasher\Hasher\PasswordHasherFactoryInterface` instead
 * Deprecate the `security.user_password_encoder.generic` service, the `security.password_encoder` and the `Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface` aliases,
   use `security.user_password_hasher`, `security.password_hasher` and `Symfony\Component\PasswordHasher\Hasher\UserPasswordHasherInterface` instead

Serializer
----------

 * Deprecated `ArrayDenormalizer::setSerializer()`, call `setDenormalizer()` instead

Uid
---

 * Replaced `UuidV1::getTime()`, `UuidV6::getTime()` and `Ulid::getTime()` by `UuidV1::getDateTime()`, `UuidV6::getDateTime()` and `Ulid::getDateTime()`

Workflow
--------

 * Deprecate `InvalidTokenConfigurationException`
