+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.

+ * 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 https://symfony.com/doc/current/deployment/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
+   behavior 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 behavior 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.
