+CHANGELOG
+=========
+
+3.4.0
+-----
+
+ * implemented PHP 7.0's `SessionUpdateTimestampHandlerInterface` with a new
+   `AbstractSessionHandler` base class and a new `StrictSessionHandler` wrapper
+ * deprecated the `WriteCheckSessionHandler`, `NativeSessionHandler` and `NativeProxy` classes
+ * deprecated setting session save handlers that do not implement `\SessionHandlerInterface` in `NativeSessionStorage::setSaveHandler()`
+ * deprecated using `MongoDbSessionHandler` with the legacy mongo extension; use it with the mongodb/mongodb package and ext-mongodb instead
+ * deprecated `MemcacheSessionHandler`; use `MemcachedSessionHandler` instead
+
+3.3.0
+-----
+
+ * the `Request::setTrustedProxies()` method takes a new `$trustedHeaderSet` argument,
+   see http://symfony.com/doc/current/components/http_foundation/trusting_proxies.html for more info,
+ * deprecated the `Request::setTrustedHeaderName()` and `Request::getTrustedHeaderName()` methods,
+ * added `File\Stream`, to be passed to `BinaryFileResponse` when the size of the served file is unknown,
+   disabling `Range` and `Content-Length` handling, switching to chunked encoding instead
+ * added the `Cookie::fromString()` method that allows to create a cookie from a
+   raw header string
+
+3.1.0
+-----
+
+ * Added support for creating `JsonResponse` with a string of JSON data
+
+3.0.0
+-----
+
+ * The precedence of parameters returned from `Request::get()` changed from "GET, PATH, BODY" to "PATH, GET, BODY"
+
+2.8.0
+-----
+
+ * Finding deep items in `ParameterBag::get()` is deprecated since version 2.8 and
+   will be removed in 3.0.
+
+2.6.0
+-----
+
+ * PdoSessionHandler changes
+   - implemented different session locking strategies to prevent loss of data by concurrent access to the same session
+   - [BC BREAK] save session data in a binary column without base64_encode
+   - [BC BREAK] added lifetime column to the session table which allows to have different lifetimes for each session
+   - implemented lazy connections that are only opened when a session is used by either passing a dsn string
+     explicitly or falling back to session.save_path ini setting
+   - added a createTable method that initializes a correctly defined table depending on the database vendor
+
+2.5.0
+-----
+
+ * added `JsonResponse::setEncodingOptions()` & `JsonResponse::getEncodingOptions()` for easier manipulation
+   of the options used while encoding data to JSON format.
+
+2.4.0
+-----
+
+ * added RequestStack
+ * added Request::getEncodings()
+ * added accessors methods to session handlers
+
+2.3.0
+-----
+
+ * added support for ranges of IPs in trusted proxies
+ * `UploadedFile::isValid` now returns false if the file was not uploaded via HTTP (in a non-test mode)
+ * Improved error-handling of `\Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler`
+   to ensure the supplied PDO handler throws Exceptions on error (as the class expects). Added related test cases
+   to verify that Exceptions are properly thrown when the PDO queries fail.
+
+2.2.0
+-----
+
+ * fixed the Request::create() precedence (URI information always take precedence now)
+ * added Request::getTrustedProxies()
+ * deprecated Request::isProxyTrusted()
+ * [BC BREAK] JsonResponse does not turn a top level empty array to an object anymore, use an ArrayObject to enforce objects
+ * added a IpUtils class to check if an IP belongs to a CIDR
+ * added Request::getRealMethod() to get the "real" HTTP method (getMethod() returns the "intended" HTTP method)
+ * disabled _method request parameter support by default (call Request::enableHttpMethodParameterOverride() to
+   enable it, and Request::getHttpMethodParameterOverride() to check if it is supported)
+ * Request::splitHttpAcceptHeader() method is deprecated and will be removed in 2.3
+ * Deprecated Flashbag::count() and \Countable interface, will be removed in 2.3
+
+2.1.0
+-----
+
+ * added Request::getSchemeAndHttpHost() and Request::getUserInfo()
+ * added a fluent interface to the Response class
+ * added Request::isProxyTrusted()
+ * added JsonResponse
+ * added a getTargetUrl method to RedirectResponse
+ * added support for streamed responses
+ * made Response::prepare() method the place to enforce HTTP specification
+ * [BC BREAK] moved management of the locale from the Session class to the Request class
+ * added a generic access to the PHP built-in filter mechanism: ParameterBag::filter()
+ * made FileBinaryMimeTypeGuesser command configurable
+ * added Request::getUser() and Request::getPassword()
+ * added support for the PATCH method in Request
+ * removed the ContentTypeMimeTypeGuesser class as it is deprecated and never used on PHP 5.3
+ * added ResponseHeaderBag::makeDisposition() (implements RFC 6266)
+ * made mimetype to extension conversion configurable
+ * [BC BREAK] Moved all session related classes and interfaces into own namespace, as
+   `Symfony\Component\HttpFoundation\Session` and renamed classes accordingly.
+   Session handlers are located in the subnamespace `Symfony\Component\HttpFoundation\Session\Handler`.
+ * SessionHandlers must implement `\SessionHandlerInterface` or extend from the
+   `Symfony\Component\HttpFoundation\Storage\Handler\NativeSessionHandler` base class.
+ * Added internal storage driver proxy mechanism for forward compatibility with
+   PHP 5.4 `\SessionHandler` class.
+ * Added session handlers for custom Memcache, Memcached and Null session save handlers.
+ * [BC BREAK] Removed `NativeSessionStorage` and replaced with `NativeFileSessionHandler`.
+ * [BC BREAK] `SessionStorageInterface` methods removed: `write()`, `read()` and
+   `remove()`.  Added `getBag()`, `registerBag()`.  The `NativeSessionStorage` class
+   is a mediator for the session storage internals including the session handlers
+   which do the real work of participating in the internal PHP session workflow.
+ * [BC BREAK] Introduced mock implementations of `SessionStorage` to enable unit
+   and functional testing without starting real PHP sessions.  Removed
+   `ArraySessionStorage`, and replaced with `MockArraySessionStorage` for unit
+   tests; removed `FilesystemSessionStorage`, and replaced with`MockFileSessionStorage`
+   for functional tests.  These do not interact with global session ini
+   configuration values, session functions or `$_SESSION` superglobal. This means
+   they can be configured directly allowing multiple instances to work without
+   conflicting in the same PHP process.
+ * [BC BREAK] Removed the `close()` method from the `Session` class, as this is
+   now redundant.
+ * Deprecated the following methods from the Session class: `setFlash()`, `setFlashes()`
+   `getFlash()`, `hasFlash()`, and `removeFlash()`. Use `getFlashBag()` instead
+   which returns a `FlashBagInterface`.
+ * `Session->clear()` now only clears session attributes as before it cleared
+   flash messages and attributes. `Session->getFlashBag()->all()` clears flashes now.
+ * Session data is now managed by `SessionBagInterface` to better encapsulate
+   session data.
+ * Refactored session attribute and flash messages system to their own
+  `SessionBagInterface` implementations.
+ * Added `FlashBag`. Flashes expire when retrieved by `get()` or `all()`. This
+   implementation is ESI compatible.
+ * Added `AutoExpireFlashBag` (default) to replicate Symfony 2.0.x auto expire
+   behaviour of messages auto expiring after one page page load.  Messages must
+   be retrieved by `get()` or `all()`.
+ * Added `Symfony\Component\HttpFoundation\Attribute\AttributeBag` to replicate
+   attributes storage behaviour from 2.0.x (default).
+ * Added `Symfony\Component\HttpFoundation\Attribute\NamespacedAttributeBag` for
+   namespace session attributes.
+ * Flash API can stores messages in an array so there may be multiple messages
+   per flash type.  The old `Session` class API remains without BC break as it
+   will allow single messages as before.
+ * Added basic session meta-data to the session to record session create time,
+   last updated time, and the lifetime of the session cookie that was provided
+   to the client.
+ * Request::getClientIp() method doesn't take a parameter anymore but bases
+   itself on the trustProxy parameter.
+ * Added isMethod() to Request object.
+ * [BC BREAK] The methods `getPathInfo()`, `getBaseUrl()` and `getBasePath()` of
+   a `Request` now all return a raw value (vs a urldecoded value before). Any call
+   to one of these methods must be checked and wrapped in a `rawurldecode()` if
+   needed.

+ * it means only one session can be accessed at a time. Even different sessions would wait
+ * for another to finish. So saving session in SQLite should only be considered for
+ * development or prototypes.
+ *
+ * Session data is a binary string that can contain non-printable characters like the null byte.
+ * For this reason it must be saved in a binary column in the database like BLOB in MySQL.
+ * Saving it in a character column could corrupt the data. You can use createTable()

+Symfony Polyfill / Php70
+========================
+
+This component provides features unavailable in releases prior to PHP 7.0:
+
+- [`intdiv`](http://php.net/intdiv)
+- [`preg_replace_callback_array`](http://php.net/preg_replace_callback_array)
+- [`error_clear_last`](http://php.net/error_clear_last)
+- `random_bytes` and `random_int` (from [paragonie/random_compat](https://github.com/paragonie/random_compat))
+- [`*Error` throwable classes](http://php.net/Error)
+- [`PHP_INT_MIN`](http://php.net/manual/en/reserved.constants.php#constant.php-int-min)
+- `SessionUpdateTimestampHandlerInterface`
+
+More information can be found in the
+[main Polyfill README](https://github.com/symfony/polyfill/blob/master/README.md).
+
+Compatibility notes
+===================
+
+To write portable code between PHP5 and PHP7, some care must be taken:
+- `\*Error` exceptions must be caught before `\Exception`;
+- after calling `error_clear_last()`, the result of `$e = error_get_last()` must be
+  verified using `isset($e['message'][0])` instead of `null !== $e`.
+
+License

+CHANGELOG
+=========
+
+3.4.0
+-----
+
+ * Added `NoConfigurationException`.
+ * Added the possibility to define a prefix for all routes of a controller via @Route(name="prefix_")
+ * Added support for prioritized routing loaders.
+ * Add matched and default parameters to redirect responses
+ * Added support for a `controller` keyword for configuring route controllers in YAML and XML configurations.
+
+3.3.0
+-----
+
+  * [DEPRECATION] Class parameters have been deprecated and will be removed in 4.0.
+    * router.options.generator_class
+    * router.options.generator_base_class
+    * router.options.generator_dumper_class
+    * router.options.matcher_class
+    * router.options.matcher_base_class
+    * router.options.matcher_dumper_class
+    * router.options.matcher.cache_class
+    * router.options.generator.cache_class
+
+3.2.0
+-----
+
+ * Added support for `bool`, `int`, `float`, `string`, `list` and `map` defaults in XML configurations.
+ * Added support for UTF-8 requirements
+
+2.8.0
+-----
+
+ * allowed specifying a directory to recursively load all routing configuration files it contains
+ * Added ObjectRouteLoader and ServiceRouteLoader that allow routes to be loaded
+   by calling a method on an object/service.
+ * [DEPRECATION] Deprecated the hardcoded value for the `$referenceType` argument of the `UrlGeneratorInterface::generate` method.
+   Use the constants defined in the `UrlGeneratorInterface` instead.
+
+   Before:
+
+   ```php
+   $router->generate('blog_show', array('slug' => 'my-blog-post'), true);
+   ```
+
+   After:
+
+   ```php
+   use Symfony\Component\Routing\Generator\UrlGeneratorInterface;
+
+   $router->generate('blog_show', array('slug' => 'my-blog-post'), UrlGeneratorInterface::ABSOLUTE_URL);
+   ```
+
+2.5.0
+-----
+
+ * [DEPRECATION] The `ApacheMatcherDumper` and `ApacheUrlMatcher` were deprecated and
+   will be removed in Symfony 3.0, since the performance gains were minimal and
+   it's hard to replicate the behaviour of PHP implementation.
+
+2.3.0
+-----
+
+ * added RequestContext::getQueryString()
+
+2.2.0
+-----
+
+ * [DEPRECATION] Several route settings have been renamed (the old ones will be removed in 3.0):
+
+    * The `pattern` setting for a route has been deprecated in favor of `path`
+    * The `_scheme` and `_method` requirements have been moved to the `schemes` and `methods` settings
+
+   Before:
+
+   ```yaml
+   article_edit:
+       pattern: /article/{id}
+       requirements: { '_method': 'POST|PUT', '_scheme': 'https', 'id': '\d+' }
+   ```
+
+   ```xml
+   <route id="article_edit" pattern="/article/{id}">
+       <requirement key="_method">POST|PUT</requirement>
+       <requirement key="_scheme">https</requirement>
+       <requirement key="id">\d+</requirement>
+   </route>
+   ```
+
+   ```php
+   $route = new Route();
+   $route->setPattern('/article/{id}');
+   $route->setRequirement('_method', 'POST|PUT');
+   $route->setRequirement('_scheme', 'https');
+   ```
+
+   After:
+
+   ```yaml
+   article_edit:
+       path: /article/{id}
+       methods: [POST, PUT]
+       schemes: https
+       requirements: { 'id': '\d+' }
+   ```
+
+   ```xml
+   <route id="article_edit" pattern="/article/{id}" methods="POST PUT" schemes="https">
+       <requirement key="id">\d+</requirement>
+   </route>
+   ```
+
+   ```php
+   $route = new Route();
+   $route->setPath('/article/{id}');
+   $route->setMethods(array('POST', 'PUT'));
+   $route->setSchemes('https');
+   ```
+
+ * [BC BREAK] RouteCollection does not behave like a tree structure anymore but as
+   a flat array of Routes. So when using PHP to build the RouteCollection, you must
+   make sure to add routes to the sub-collection before adding it to the parent
+   collection (this is not relevant when using YAML or XML for Route definitions).
+
+   Before:
+
+   ```php
+   $rootCollection = new RouteCollection();
+   $subCollection = new RouteCollection();
+   $rootCollection->addCollection($subCollection);
+   $subCollection->add('foo', new Route('/foo'));
+   ```
+
+   After:
+
+   ```php
+   $rootCollection = new RouteCollection();
+   $subCollection = new RouteCollection();
+   $subCollection->add('foo', new Route('/foo'));
+   $rootCollection->addCollection($subCollection);
+   ```
+
+   Also one must call `addCollection` from the bottom to the top hierarchy.
+   So the correct sequence is the following (and not the reverse):
+
+   ```php
+   $childCollection->addCollection($grandchildCollection);
+   $rootCollection->addCollection($childCollection);
+   ```
+
+ * [DEPRECATION] The methods `RouteCollection::getParent()` and `RouteCollection::getRoot()`
+   have been deprecated and will be removed in Symfony 2.3.
+ * [BC BREAK] Misusing the `RouteCollection::addPrefix` method to add defaults, requirements
+   or options without adding a prefix is not supported anymore. So if you called `addPrefix`
+   with an empty prefix or `/` only (both have no relevance), like
+   `addPrefix('', $defaultsArray, $requirementsArray, $optionsArray)`
+   you need to use the new dedicated methods `addDefaults($defaultsArray)`,
+   `addRequirements($requirementsArray)` or `addOptions($optionsArray)` instead.
+ * [DEPRECATION] The `$options` parameter to `RouteCollection::addPrefix()` has been deprecated
+   because adding options has nothing to do with adding a path prefix. If you want to add options
+   to all child routes of a RouteCollection, you can use `addOptions()`.
+ * [DEPRECATION] The method `RouteCollection::getPrefix()` has been deprecated
+   because it suggested that all routes in the collection would have this prefix, which is
+   not necessarily true. On top of that, since there is no tree structure anymore, this method
+   is also useless. Don't worry about performance, prefix optimization for matching is still done
+   in the dumper, which was also improved in 2.2.0 to find even more grouping possibilities.
+ * [DEPRECATION] `RouteCollection::addCollection(RouteCollection $collection)` should now only be
+   used with a single parameter. The other params `$prefix`, `$default`, `$requirements` and `$options`
+   will still work, but have been deprecated. The `addPrefix` method should be used for this
+   use-case instead.
+   Before: `$parentCollection->addCollection($collection, '/prefix', array(...), array(...))`
+   After:
+   ```php
+   $collection->addPrefix('/prefix', array(...), array(...));
+   $parentCollection->addCollection($collection);
+   ```
+ * added support for the method default argument values when defining a @Route
+ * Adjacent placeholders without separator work now, e.g. `/{x}{y}{z}.{_format}`.
+ * Characters that function as separator between placeholders are now whitelisted
+   to fix routes with normal text around a variable, e.g. `/prefix{var}suffix`.
+ * [BC BREAK] The default requirement of a variable has been changed slightly.
+   Previously it disallowed the previous and the next char around a variable. Now
+   it disallows the slash (`/`) and the next char. Using the previous char added
+   no value and was problematic because the route `/index.{_format}` would be
+   matched by `/index.ht/ml`.
+ * The default requirement now uses possessive quantifiers when possible which
+   improves matching performance by up to 20% because it prevents backtracking
+   when it's not needed.
+ * The ConfigurableRequirementsInterface can now also be used to disable the requirements
+   check on URL generation completely by calling `setStrictRequirements(null)`. It
+   improves performance in production environment as you should know that params always
+   pass the requirements (otherwise it would break your link anyway).
+ * There is no restriction on the route name anymore. So non-alphanumeric characters
+   are now also allowed.
+ * [BC BREAK] `RouteCompilerInterface::compile(Route $route)` was made static
+   (only relevant if you implemented your own RouteCompiler).
+ * Added possibility to generate relative paths and network paths in the UrlGenerator, e.g.
+   "../parent-file" and "//example.com/dir/file". The third parameter in
+   `UrlGeneratorInterface::generate($name, $parameters = array(), $referenceType = self::ABSOLUTE_PATH)`
+   now accepts more values and you should use the constants defined in `UrlGeneratorInterface` for
+   claritiy. The old method calls with a Boolean parameter will continue to work because they
+   equal the signature using the constants.
+
+2.1.0
+-----
+
+ * added RequestMatcherInterface
+ * added RequestContext::fromRequest()
+ * the UrlMatcher does not throw a \LogicException anymore when the required
+   scheme is not the current one
+ * added TraceableUrlMatcher
+ * added the possibility to define options, default values and requirements
+   for placeholders in prefix, including imported routes
+ * added RouterInterface::getRouteCollection
+ * [BC BREAK] the UrlMatcher urldecodes the route parameters only once, they
+   were decoded twice before. Note that the `urldecode()` calls have been
+   changed for a single `rawurldecode()` in order to support `+` for input
+   paths.
+ * added RouteCollection::getRoot method to retrieve the root of a
+   RouteCollection tree
+ * [BC BREAK] made RouteCollection::setParent private which could not have
+   been used anyway without creating inconsistencies
+ * [BC BREAK] RouteCollection::remove also removes a route from parent
+   collections (not only from its children)
+ * added ConfigurableRequirementsInterface that allows to disable exceptions
+   (and generate empty URLs instead) when generating a route with an invalid
+   parameter value

+ *   production environment. It should log the mismatch so one can review it.
+ * - setStrictRequirements(null): Return the URL with the given parameters without
+ *   checking the requirements at all. When generating a URL you should either trust
+ *   your params or you validated them beforehand because otherwise it would break your
+ *   link anyway. So in production environment you should know that params always pass
+ *   the requirements. Thus this option allows to disable the check on URL generation for

+/**
+ * AnnotationClassLoader loads routing information from a PHP class and its methods.
+ *
+ * You need to define an implementation for the getRouteDefaults() method. Most of the
+ * time, this method should define some PHP callable to be called for the route
+ * (a controller in MVC speak).
+ *
+ * The @Route annotation can be set on the class (for global parameters),
+ * and on each method.
+ *
+ * The @Route annotation main value is the route path. The annotation also
+ * recognizes several parameters: requirements, options, defaults, schemes,
+ * methods, host, and name. The name parameter is mandatory.
+ * Here is an example of how you should be able to use it:
+ *
+ *     /**
+ *      * @Route("/Blog")
+ *      * /
+ *     class Blog
+ *     {
+ *         /**
+ *          * @Route("/", name="blog_index")
+ *          * /
+ *         public function index()
+ *         {
+ *         }
+ *
+ *         /**
+ *          * @Route("/{id}", name="blog_post", requirements = {"id" = "\d+"})
+ *          * /
+ *         public function show()
+ *         {
+ *         }
+ *     }
