+## Changelog
+
+### 1.6.1
+
+This release fixes an issue in which annotations such as `@foo-bar`
+and `@foo-` were incorrectly recognised as valid, and both erroneously
+parsed as `@foo`.
+
+Any annotation with `@name-*` format will now silently be ignored,
+allowing vendor-specific annotations to be prefixed with the tool
+name.

+### 1.3.1 - 2016-12-30
+
+This release fixes an issue with ignored annotations that were already
+autoloaded, causing the `SimpleAnnotationReader` to pick them up
+anyway. [#110](https://github.com/doctrine/annotations/pull/110)
+
+Additionally, an issue was fixed in the `CachedReader`, which was
+not correctly checking the freshness of cached annotations when
+traits were defined on a class. [#105](https://github.com/doctrine/annotations/pull/105)
+
+Total issues resolved: **2**
+
+- [105: Return single max timestamp](https://github.com/doctrine/annotations/pull/105)

+
+### 1.3.0
+
+This release introduces a PHP version bump. `doctrine/annotations` now requires PHP
+5.6 or later to be installed.
+
+A series of additional improvements have been introduced:
+
+ * support for PHP 7 "grouped use statements"
+ * support for ignoring entire namespace names
+   via `Doctrine\Common\Annotations\AnnotationReader::addGlobalIgnoredNamespace()` and
+   `Doctrine\Common\Annotations\DocParser::setIgnoredAnnotationNamespaces()`. This will
+   allow you to ignore annotations from namespaces that you cannot autoload
+ * testing all parent classes and interfaces when checking if the annotation cache
+   in the `CachedReader` is fresh
+ * simplifying the cache keys used by the `CachedReader`: keys are no longer artificially
+   namespaced, since `Doctrine\Common\Cache` already supports that
+ * corrected parsing of multibyte strings when `mbstring.func_overload` is enabled
+ * corrected parsing of annotations when `"\t"` is put before the first annotation
+   in a docblock
+ * allow skipping non-imported annotations when a custom `DocParser` is passed to
+   the `AnnotationReader` constructor
+

+Handling Annotations
+====================
+
+There are several different approaches to handling annotations in PHP.
+Doctrine Annotations maps docblock annotations to PHP classes. Because
+not all docblock annotations are used for metadata purposes a filter is
+applied to ignore or skip classes that are not Doctrine annotations.
+
+Take a look at the following code snippet:
+
+.. code-block:: php
+
+    namespace MyProject\Entities;
+
+    use Doctrine\ORM\Mapping AS ORM;
+    use Symfony\Component\Validation\Constraints AS Assert;
+
+    /**
+     * @author Benjamin Eberlei
+     * @ORM\Entity
+     * @MyProject\Annotations\Foobarable
+     */
+    class User
+    {
+        /**
+         * @ORM\Id @ORM\Column @ORM\GeneratedValue
+         * @dummy
+         * @var int
+         */
+        private $id;
+
+        /**
+         * @ORM\Column(type="string")
+         * @Assert\NotEmpty
+         * @Assert\Email
+         * @var string
+         */
+        private $email;
+    }
+
+In this snippet you can see a variety of different docblock annotations:
+
+- Documentation annotations such as ``@var`` and ``@author``. These
+  annotations are on a blacklist and never considered for throwing an
+  exception due to wrongly used annotations.
+- Annotations imported through use statements. The statement ``use
+  Doctrine\ORM\Mapping AS ORM`` makes all classes under that namespace
+  available as ``@ORM\ClassName``. Same goes for the import of
+  ``@Assert``.
+- The ``@dummy`` annotation. It is not a documentation annotation and
+  not blacklisted. For Doctrine Annotations it is not entirely clear how
+  to handle this annotation. Depending on the configuration an exception
+  (unknown annotation) will be thrown when parsing this annotation.
+- The fully qualified annotation ``@MyProject\Annotations\Foobarable``.
+  This is transformed directly into the given class name.
+
+How are these annotations loaded? From looking at the code you could
+guess that the ORM Mapping, Assert Validation and the fully qualified
+annotation can just be loaded using
+the defined PHP autoloaders. This is not the case however: For error
+handling reasons every check for class existence inside the
+``AnnotationReader`` sets the second parameter $autoload
+of ``class_exists($name, $autoload)`` to false. To work flawlessly the
+``AnnotationReader`` requires silent autoloaders which many autoloaders are
+not. Silent autoloading is NOT part of the `PSR-0 specification
+<https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md>`_
+for autoloading.
+
+This is why Doctrine Annotations uses its own autoloading mechanism
+through a global registry. If you are wondering about the annotation
+registry being global, there is no other way to solve the architectural
+problems of autoloading annotation classes in a straightforward fashion.
+Additionally if you think about PHP autoloading then you recognize it is
+a global as well.
+
+To anticipate the configuration section, making the above PHP class work
+with Doctrine Annotations requires this setup:
+
+.. code-block:: php
+
+    use Doctrine\Common\Annotations\AnnotationReader;
+    use Doctrine\Common\Annotations\AnnotationRegistry;
+
+    AnnotationRegistry::registerFile("/path/to/doctrine/lib/Doctrine/ORM/Mapping/Driver/DoctrineAnnotations.php");
+    AnnotationRegistry::registerAutoloadNamespace("Symfony\Component\Validator\Constraint", "/path/to/symfony/src");
+    AnnotationRegistry::registerAutoloadNamespace("MyProject\Annotations", "/path/to/myproject/src");
+
+    $reader = new AnnotationReader();
+    AnnotationReader::addGlobalIgnoredName('dummy');
+
+The second block with the annotation registry calls registers all the
+three different annotation namespaces that are used.
+Doctrine Annotations saves all its annotations in a single file, that is
+why ``AnnotationRegistry#registerFile`` is used in contrast to
+``AnnotationRegistry#registerAutoloadNamespace`` which creates a PSR-0
+compatible loading mechanism for class to file names.
+
+In the third block, we create the actual ``AnnotationReader`` instance.
+Note that we also add ``dummy`` to the global list of ignored
+annotations for which we do not throw exceptions. Setting this is
+necessary in our example case, otherwise ``@dummy`` would trigger an
+exception to be thrown during the parsing of the docblock of
+``MyProject\Entities\User#id``.
+
+Setup and Configuration
+-----------------------
+
+To use the annotations library is simple, you just need to create a new
+``AnnotationReader`` instance:
+
+.. code-block:: php
+
+    $reader = new \Doctrine\Common\Annotations\AnnotationReader();
+
+This creates a simple annotation reader with no caching other than in
+memory (in php arrays). Since parsing docblocks can be expensive you
+should cache this process by using a caching reader.
+
+You can use a file caching reader, but please note it is deprecated to
+do so:
+
+.. code-block:: php
+
+    use Doctrine\Common\Annotations\FileCacheReader;
+    use Doctrine\Common\Annotations\AnnotationReader;
+
+    $reader = new FileCacheReader(
+        new AnnotationReader(),
+        "/path/to/cache",
+        $debug = true
+    );
+
+If you set the ``debug`` flag to ``true`` the cache reader will check
+for changes in the original files, which is very important during
+development. If you don't set it to ``true`` you have to delete the
+directory to clear the cache. This gives faster performance, however
+should only be used in production, because of its inconvenience during
+development.
+
+You can also use one of the ``Doctrine\Common\Cache\Cache`` cache
+implementations to cache the annotations:
+
+.. code-block:: php
+
+    use Doctrine\Common\Annotations\AnnotationReader;
+    use Doctrine\Common\Annotations\CachedReader;
+    use Doctrine\Common\Cache\ApcCache;
+
+    $reader = new CachedReader(
+        new AnnotationReader(),
+        new ApcCache(),
+        $debug = true
+    );
+
+The ``debug`` flag is used here as well to invalidate the cache files
+when the PHP class with annotations changed and should be used during
+development.
+
+.. warning ::
+
+    The ``AnnotationReader`` works and caches under the
+    assumption that all annotations of a doc-block are processed at
+    once. That means that annotation classes that do not exist and
+    aren't loaded and cannot be autoloaded (using the
+    AnnotationRegistry) would never be visible and not accessible if a
+    cache is used unless the cache is cleared and the annotations
+    requested again, this time with all annotations defined.
+
+By default the annotation reader returns a list of annotations with
+numeric indexes. If you want your annotations to be indexed by their
+class name you can wrap the reader in an ``IndexedReader``:
+
+.. code-block:: php
+
+    use Doctrine\Common\Annotations\AnnotationReader;
+    use Doctrine\Common\Annotations\IndexedReader;
+
+    $reader = new IndexedReader(new AnnotationReader());
+
+.. warning::
+
+    You should never wrap the indexed reader inside a cached reader,
+    only the other way around. This way you can re-use the cache with
+    indexed or numeric keys, otherwise your code may experience failures
+    due to caching in a numerical or indexed format.
+
+Registering Annotations
+~~~~~~~~~~~~~~~~~~~~~~~
+
+As explained in the introduction, Doctrine Annotations uses its own
+autoloading mechanism to determine if a given annotation has a
+corresponding PHP class that can be autoloaded. For annotation
+autoloading you have to configure the
+``Doctrine\Common\Annotations\AnnotationRegistry``. There are three
+different mechanisms to configure annotation autoloading:
+
+- Calling ``AnnotationRegistry#registerFile($file)`` to register a file
+  that contains one or more annotation classes.
+- Calling ``AnnotationRegistry#registerNamespace($namespace, $dirs =
+  null)`` to register that the given namespace contains annotations and
+  that their base directory is located at the given $dirs or in the
+  include path if ``NULL`` is passed. The given directories should *NOT*
+  be the directory where classes of the namespace are in, but the base
+  directory of the root namespace. The AnnotationRegistry uses a
+  namespace to directory separator approach to resolve the correct path.
+- Calling ``AnnotationRegistry#registerLoader($callable)`` to register
+  an autoloader callback. The callback accepts the class as first and
+  only parameter and has to return ``true`` if the corresponding file
+  was found and included.
+
+.. note::
+
+    Loaders have to fail silently, if a class is not found even if it
+    matches for example the namespace prefix of that loader. Never is a
+    loader to throw a warning or exception if the loading failed
+    otherwise parsing doc block annotations will become a huge pain.
+
+A sample loader callback could look like:
+
+.. code-block:: php
+
+    use Doctrine\Common\Annotations\AnnotationRegistry;
+    use Symfony\Component\ClassLoader\UniversalClassLoader;
+
+    AnnotationRegistry::registerLoader(function($class) {
+        $file = str_replace("\\", DIRECTORY_SEPARATOR, $class) . ".php";
+
+        if (file_exists("/my/base/path/" . $file)) {
+            // file_exists() makes sure that the loader fails silently
+            require "/my/base/path/" . $file;
+        }
+    });
+
+    $loader = new UniversalClassLoader();
+    AnnotationRegistry::registerLoader(array($loader, "loadClass"));
+
+
+Ignoring missing exceptions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default an exception is thrown from the ``AnnotationReader`` if an
+annotation was found that:
+
+- is not part of the blacklist of ignored "documentation annotations";
+- was not imported through a use statement;
+- is not a fully qualified class that exists.
+
+You can disable this behavior for specific names if your docblocks do
+not follow strict requirements:
+
+.. code-block:: php
+
+    $reader = new \Doctrine\Common\Annotations\AnnotationReader();
+    AnnotationReader::addGlobalIgnoredName('foo');
+
+PHP Imports
+~~~~~~~~~~~
+
+By default the annotation reader parses the use-statement of a php file
+to gain access to the import rules and register them for the annotation
+processing. Only if you are using PHP Imports can you validate the
+correct usage of annotations and throw exceptions if you misspelled an
+annotation. This mechanism is enabled by default.
+
+To ease the upgrade path, we still allow you to disable this mechanism.
+Note however that we will remove this in future versions:
+
+.. code-block:: php
+
+    $reader = new \Doctrine\Common\Annotations\AnnotationReader();
+    $reader->setEnabledPhpImports(false);

+Custom Annotation Classes
+=========================
+
+If you want to define your own annotations, you just have to group them
+in a namespace and register this namespace in the ``AnnotationRegistry``.
+Annotation classes have to contain a class-level docblock with the text
+``@Annotation``:
+
+.. code-block:: php
+
+    namespace MyCompany\Annotations;
+
+    /** @Annotation */
+    class Bar
+    {
+        // some code
+    }
+
+Inject annotation values
+------------------------
+
+The annotation parser checks if the annotation constructor has arguments,
+if so then it will pass the value array, otherwise it will try to inject
+values into public properties directly:
+
+
+.. code-block:: php
+
+    namespace MyCompany\Annotations;
+
+    /**
+     * @Annotation
+     *
+     * Some Annotation using a constructor
+     */
+    class Bar
+    {
+        private $foo;
+
+        public function __construct(array $values)
+        {
+            $this->foo = $values['foo'];
+        }
+    }
+
+    /**
+     * @Annotation
+     *
+     * Some Annotation without a constructor
+     */
+    class Foo
+    {
+        public $bar;
+    }
+
+Annotation Target
+-----------------
+
+``@Target`` indicates the kinds of class elements to which an annotation
+type is applicable. Then you could define one or more targets:
+
+-  ``CLASS`` Allowed in class docblocks
+-  ``PROPERTY`` Allowed in property docblocks
+-  ``METHOD`` Allowed in the method docblocks
+-  ``ALL`` Allowed in class, property and method docblocks
+-  ``ANNOTATION`` Allowed inside other annotations
+
+If the annotations is not allowed in the current context, an
+``AnnotationException`` is thrown.
+
+.. code-block:: php
+
+    namespace MyCompany\Annotations;
+
+    /**
+     * @Annotation
+     * @Target({"METHOD","PROPERTY"})
+     */
+    class Bar
+    {
+        // some code
+    }
+
+    /**
+     * @Annotation
+     * @Target("CLASS")
+     */
+    class Foo
+    {
+        // some code
+    }
+
+Attribute types
+---------------
+
+The annotation parser checks the given parameters using the phpdoc
+annotation ``@var``, The data type could be validated using the ``@var``
+annotation on the annotation properties or using the ``@Attributes`` and
+``@Attribute`` annotations.
+
+If the data type does not match you get an ``AnnotationException``
+
+.. code-block:: php
+
+    namespace MyCompany\Annotations;
+
+    /**
+     * @Annotation
+     * @Target({"METHOD","PROPERTY"})
+     */
+    class Bar
+    {
+        /** @var mixed */
+        public $mixed;
+
+        /** @var boolean */
+        public $boolean;
+
+        /** @var bool */
+        public $bool;
+
+        /** @var float */
+        public $float;
+
+        /** @var string */
+        public $string;
+
+        /** @var integer */
+        public $integer;
+
+        /** @var array */
+        public $array;
+
+        /** @var SomeAnnotationClass */
+        public $annotation;
+
+        /** @var array<integer> */
+        public $arrayOfIntegers;
+
+        /** @var array<SomeAnnotationClass> */
+        public $arrayOfAnnotations;
+    }
+
+    /**
+     * @Annotation
+     * @Target({"METHOD","PROPERTY"})
+     * @Attributes({
+     *   @Attribute("stringProperty", type = "string"),
+     *   @Attribute("annotProperty",  type = "SomeAnnotationClass"),
+     * })
+     */
+    class Foo
+    {
+        public function __construct(array $values)
+        {
+            $this->stringProperty = $values['stringProperty'];
+            $this->annotProperty = $values['annotProperty'];
+        }
+
+        // some code
+    }
+
+Annotation Required
+-------------------
+
+``@Required`` indicates that the field must be specified when the
+annotation is used. If it is not used you get an ``AnnotationException``
+stating that this value can not be null.
+
+Declaring a required field:
+
+.. code-block:: php
+
+    /**
+     * @Annotation
+     * @Target("ALL")
+     */
+    class Foo
+    {
+        /** @Required */
+        public $requiredField;
+    }
+
+Usage:
+
+.. code-block:: php
+
+    /** @Foo(requiredField="value") */
+    public $direction;                  // Valid
+
+     /** @Foo */
+    public $direction;                  // Required field missing, throws an AnnotationException
+
+
+Enumerated values
+-----------------
+
+- An annotation property marked with ``@Enum`` is a field that accepts a
+  fixed set of scalar values.
+- You should use ``@Enum`` fields any time you need to represent fixed
+  values.
+- The annotation parser checks the given value and throws an
+  ``AnnotationException`` if the value does not match.
+
+
+Declaring an enumerated property:
+
+.. code-block:: php
+
+    /**
+     * @Annotation
+     * @Target("ALL")
+     */
+    class Direction
+    {
+        /**
+         * @Enum({"NORTH", "SOUTH", "EAST", "WEST"})
+         */
+        public $value;
+    }
+
+Annotation usage:
+
+.. code-block:: php
+
+    /** @Direction("NORTH") */
+    public $direction;                  // Valid value
+
+     /** @Direction("NORTHEAST") */
+    public $direction;                  // Invalid value, throws an AnnotationException
+
+
+Constants
+---------
+
+The use of constants and class constants is available on the annotations
+parser.
+
+The following usages are allowed:
+
+.. code-block:: php
+
+    namespace MyCompany\Entity;
+
+    use MyCompany\Annotations\Foo;
+    use MyCompany\Annotations\Bar;
+    use MyCompany\Entity\SomeClass;
+
+    /**
+     * @Foo(PHP_EOL)
+     * @Bar(Bar::FOO)
+     * @Foo({SomeClass::FOO, SomeClass::BAR})
+     * @Bar({SomeClass::FOO_KEY = SomeClass::BAR_VALUE})
+     */
+    class User
+    {
+    }
+
+
+Be careful with constants and the cache !
+
+.. note::
+
+    The cached reader will not re-evaluate each time an annotation is
+    loaded from cache. When a constant is changed the cache must be
+    cleaned.
+
+
+Usage
+-----
+
+Using the library API is simple. Using the annotations described in the
+previous section, you can now annotate other classes with your
+annotations:
+
+.. code-block:: php
+
+    namespace MyCompany\Entity;
+
+    use MyCompany\Annotations\Foo;
+    use MyCompany\Annotations\Bar;
+
+    /**
+     * @Foo(bar="foo")
+     * @Bar(foo="bar")
+     */
+    class User
+    {
+    }
+
+Now we can write a script to get the annotations above:
+
+.. code-block:: php
+
+    $reflClass = new ReflectionClass('MyCompany\Entity\User');
+    $classAnnotations = $reader->getClassAnnotations($reflClass);
+
+    foreach ($classAnnotations AS $annot) {
+        if ($annot instanceof \MyCompany\Annotations\Foo) {
+            echo $annot->bar; // prints "foo";
+        } else if ($annot instanceof \MyCompany\Annotations\Bar) {
+            echo $annot->foo; // prints "bar";
+        }
+    }
+
+You have a complete API for retrieving annotation class instances from a
+class, property or method docblock:

+Introduction
+============
+
+Doctrine Annotations allows to implement custom annotation
+functionality for PHP classes.
+
+.. code-block:: php
+
+    class Foo
+    {
+        /**
+         * @MyAnnotation(myProperty="value")
+         */
+        private $bar;
+    }
+
+Annotations aren't implemented in PHP itself which is why this component
+offers a way to use the PHP doc-blocks as a place for the well known
+annotation syntax using the ``@`` char.
+
+Annotations in Doctrine are used for the ORM configuration to build the
+class mapping, but it can be used in other projects for other purposes
+too.
+
+Installation
+============
+
+You can install the Annotation component with composer:
+
+.. code-block::
+
+    $ composer require doctrine/annotations
+
+Create an annotation class
+==========================
+
+An annotation class is a representation of the later used annotation
+configuration in classes. The annotation class of the previous example
+looks like this:
+
+.. code-block:: php
+
+    /**
+     * @Annotation
+     */
+    final class MyAnnotation
+    {
+        public $myProperty;
+    }
+
+The annotation class is declared as an annotation by ``@Annotation``.
+
+:ref:`Read more about custom annotations. <custom>`
+
+Reading annotations
+===================
+
+The access to the annotations happens by reflection of the class
+containing them. There are multiple reader-classes implementing the
+``Doctrine\Common\Annotations\Reader`` interface, that can access the
+annotations of a class. A common one is
+``Doctrine\Common\Annotations\AnnotationReader``:
+
+.. code-block:: php
+
+    use Doctrine\Common\Annotations\AnnotationReader;
+    use Doctrine\Common\Annotations\AnnotationRegistry;
+
+    // Deprecated and will be removed in 2.0 but currently needed
+    AnnotationRegistry::registerLoader('class_exists');
+
+    $reflectionClass = new ReflectionClass(Foo::class);
+    $property = $reflectionClass->getProperty('bar');
+
+    $reader = new AnnotationReader();
+    $myAnnotation = $reader->getPropertyAnnotation($property, MyAnnotation::class);
+
+    echo $myAnnotation->myProperty; // result: "value"
+
+Note that ``AnnotationRegistry::registerLoader('class_exists')`` only works
+if you already have an autoloader configured (i.e. composer autoloader).
+Otherwise, :ref:`please take a look to the other annotation autoload mechanisms <annotations>`.
+
+A reader has multiple methods to access the annotations of a class.
+
+:ref:`Read more about handling annotations. <annotations>`
+
+IDE Support
+-----------
+
+Some IDEs already provide support for annotations:
+
+- Eclipse via the `Symfony2 Plugin <http://symfony.dubture.com/>`_
+- PHPStorm via the `PHP Annotations Plugin <http://plugins.jetbrains.com/plugin/7320>`_ or the `Symfony2 Plugin <http://plugins.jetbrains.com/plugin/7219>`_

+Symfony Deprecation Contracts
+=============================
+
+A generic function and convention to trigger deprecation notices.
+
+This package provides a single global function named `trigger_deprecation()` that triggers silenced deprecation notices.
+
+By using a custom PHP error handler such as the one provided by the Symfony ErrorHandler component,
+the triggered deprecations can be caught and logged for later discovery, both on dev and prod environments.
+
+The function requires at least 3 arguments:
+ - the name of the Composer package that is triggering the deprecation
+ - the version of the package that introduced the deprecation
+ - the message of the deprecation
+ - more arguments can be provided: they will be inserted in the message using `printf()` formatting
+
+Example:
+```php
+trigger_deprecation('symfony/blockchain', '8.9', 'Using "%s" is deprecated, use "%s" instead.', 'bitcoin', 'fabcoin');
+```
+
+This will generate the following message:
+`Since symfony/blockchain 8.9: Using "bitcoin" is deprecated, use "fabcoin" instead.`
+
+While not necessarily recommended, the deprecation notices can be completely ignored by declaring an empty
+`function trigger_deprecation() {}` in your application.

+
+   ```yaml
+   Yaml::parse('0o72');
+   ```
+
+ * Added `yaml-lint` binary.
+ * Deprecated using the `!php/object` and `!php/const` tags without a value.
+
+5.0.0
+-----
+
+ * Removed support for mappings inside multi-line strings.
+ * removed support for implicit STDIN usage in the `lint:yaml` command, use `lint:yaml -` (append a dash) instead to make it explicit.
+
+4.4.0
+-----
+
+ * Added support for parsing the inline notation spanning multiple lines.
+ * Added support to dump `null` as `~` by using the `Yaml::DUMP_NULL_AS_TILDE` flag.
+ * deprecated accepting STDIN implicitly when using the `lint:yaml` command, use `lint:yaml -` (append a dash) instead to make it explicit.
+
+4.3.0
+-----
+
+ * Using a mapping inside a multi-line string is deprecated and will throw a `ParseException` in 5.0.
+
+4.2.0
+-----
+
+ * added support for multiple files or directories in `LintCommand`
+
+4.0.0
+-----
+
+ * The behavior of the non-specific tag `!` is changed and now forces
+   non-evaluating your values.
+ * complex mappings will throw a `ParseException`
+ * support for the comma as a group separator for floats has been dropped, use
+   the underscore instead
+ * support for the `!!php/object` tag has been dropped, use the `!php/object`
+   tag instead
+ * duplicate mapping keys throw a `ParseException`
+ * non-string mapping keys throw a `ParseException`, use the `Yaml::PARSE_KEYS_AS_STRINGS`
+   flag to cast them to strings
+ * `%` at the beginning of an unquoted string throw a `ParseException`
+ * mappings with a colon (`:`) that is not followed by a whitespace throw a
+   `ParseException`
+ * the `Dumper::setIndentation()` method has been removed
+ * being able to pass boolean options to the `Yaml::parse()`, `Yaml::dump()`,
+   `Parser::parse()`, and `Dumper::dump()` methods to configure the behavior of
+   the parser and dumper is no longer supported, pass bitmask flags instead
+ * the constructor arguments of the `Parser` class have been removed
+ * the `Inline` class is internal and no longer part of the BC promise
+ * removed support for the `!str` tag, use the `!!str` tag instead
+ * added support for tagged scalars.
+
+   ```yml
+   Yaml::parse('!foo bar', Yaml::PARSE_CUSTOM_TAGS);
+   // returns TaggedValue('foo', 'bar');
+   ```
+
+3.4.0
+-----
+
+ * added support for parsing YAML files using the `Yaml::parseFile()` or `Parser::parseFile()` method
+
+ * the `Dumper`, `Parser`, and `Yaml` classes are marked as final
+
+ * Deprecated the `!php/object:` tag which will be replaced by the
+   `!php/object` tag (without the colon) in 4.0.
+
+ * Deprecated the `!php/const:` tag which will be replaced by the
+   `!php/const` tag (without the colon) in 4.0.
+
+ * Support for the `!str` tag is deprecated, use the `!!str` tag instead.
+
+ * Deprecated using the non-specific tag `!` as its behavior will change in 4.0.
+   It will force non-evaluating your values in 4.0. Use plain integers or `!!float` instead.
+
+3.3.0
+-----
+
+ * Starting an unquoted string with a question mark followed by a space is
+   deprecated and will throw a `ParseException` in Symfony 4.0.
+
+ * Deprecated support for implicitly parsing non-string mapping keys as strings.
+   Mapping keys that are no strings will lead to a `ParseException` in Symfony
+   4.0. Use quotes to opt-in for keys to be parsed as strings.
+
+   Before:
+
+   ```php
+   $yaml = <<<YAML
+   null: null key
+   true: boolean true
+   2.0: float key
+   YAML;
+
+   Yaml::parse($yaml);
+   ```
+
+   After:
+
+   ```php
+
+   $yaml = <<<YAML
+   "null": null key
+   "true": boolean true
+   "2.0": float key
+   YAML;
+
+   Yaml::parse($yaml);
+   ```
+
+ * Omitted mapping values will be parsed as `null`.
+
+ * Omitting the key of a mapping is deprecated and will throw a `ParseException` in Symfony 4.0.
+
+ * Added support for dumping empty PHP arrays as YAML sequences:
+
+   ```php
+   Yaml::dump([], 0, 0, Yaml::DUMP_EMPTY_ARRAY_AS_SEQUENCE);
+   ```
+
+3.2.0
+-----
+
+ * Mappings with a colon (`:`) that is not followed by a whitespace are deprecated
+   when the mapping key is not quoted and will lead to a `ParseException` in
+   Symfony 4.0 (e.g. `foo:bar` must be `foo: bar`).
+
+ * Added support for parsing PHP constants:
+
+   ```php
+   Yaml::parse('!php/const:PHP_INT_MAX', Yaml::PARSE_CONSTANT);
+   ```
+
+ * Support for silently ignoring duplicate mapping keys in YAML has been
+   deprecated and will lead to a `ParseException` in Symfony 4.0.
+
+3.1.0
+-----
+
+ * Added support to dump `stdClass` and `ArrayAccess` objects as YAML mappings
+   through the `Yaml::DUMP_OBJECT_AS_MAP` flag.
+
+ * Strings that are not UTF-8 encoded will be dumped as base64 encoded binary
+   data.
+
+ * Added support for dumping multi line strings as literal blocks.
+
+ * Added support for parsing base64 encoded binary data when they are tagged
+   with the `!!binary` tag.
+
+ * Added support for parsing timestamps as `\DateTime` objects:
+
+   ```php
+   Yaml::parse('2001-12-15 21:59:43.10 -5', Yaml::PARSE_DATETIME);
+   ```
+
+ * `\DateTime` and `\DateTimeImmutable` objects are dumped as YAML timestamps.
+
+ * Deprecated usage of `%` at the beginning of an unquoted string.
+
+ * Added support for customizing the YAML parser behavior through an optional bit field:
+
+   ```php
+   Yaml::parse('{ "foo": "bar", "fiz": "cat" }', Yaml::PARSE_EXCEPTION_ON_INVALID_TYPE | Yaml::PARSE_OBJECT | Yaml::PARSE_OBJECT_FOR_MAP);
+   ```
+
+ * Added support for customizing the dumped YAML string through an optional bit field:
+
+   ```php
+   Yaml::dump(['foo' => new A(), 'bar' => 1], 0, 0, Yaml::DUMP_EXCEPTION_ON_INVALID_TYPE | Yaml::DUMP_OBJECT);
+   ```
+
+3.0.0
+-----
+
+ * Yaml::parse() now throws an exception when a blackslash is not escaped
+   in double-quoted strings
+
+2.8.0
+-----
+
+ * Deprecated usage of a colon in an unquoted mapping value
+ * Deprecated usage of @, \`, | and > at the beginning of an unquoted string
+ * When surrounding strings with double-quotes, you must now escape `\` characters. Not
+   escaping those characters (when surrounded by double-quotes) is deprecated.
+
+   Before:
+
+   ```yml
+   class: "Foo\Var"
+   ```
+
+   After:
+
+   ```yml
+   class: "Foo\\Var"
+   ```
+
+2.1.0
+-----
+
+ * Yaml::parse() does not evaluate loaded files as PHP files by default
+   anymore (call Yaml::enablePhpParsing() to get back the old behavior)
