-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.

- * Locking is necessary to prevent loss of data due to race conditions and to keep
- * the session data consistent between read() and write(). With locking, requests
- * for the same session will wait until the other one finished writing. For this
- * reason it's best practice to close a session as early as possible to improve
- * concurrency. PHPs internal files session handler also implements locking.
- *
- * Attention: Since SQLite does not support row level locks but locks the whole database,
- * 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()
- * to initialize a correctly defined table.
