-## 1.4.0 - 2017-02-21
 
-* Fix `Stream::read` when length parameter <= 0.
-* `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
-* Fix `ServerRequest::getUriFromGlobals` when `Host` header contains port.
-* Ensure `ServerRequest::getUriFromGlobals` returns a URI in absolute form.
-* Allow `parse_response` to parse a response without delimiting space and reason.
-* Ensure each URI modification results in a valid URI according to PSR-7 discussions.
-  Invalid modifications will throw an exception instead of returning a wrong URI or
-  doing some magic.
-  - `(new Uri)->withPath('foo')->withHost('example.com')` will throw an exception
-    because the path of a URI with an authority must start with a slash "/" or be empty
-  - `(new Uri())->withScheme('http')` will return `'http://localhost'`

 it with a higher priority than response error handlers, because once a response
 is returned, the following handlers are ignored.

-Symfony Debug Extension for PHP 5
-=================================
-
-This extension publishes several functions to help building powerful debugging tools.
-It is compatible with PHP 5.3, 5.4, 5.5 and 5.6; with ZTS and non-ZTS modes.
-It is not required thus not provided for PHP 7.
-
-symfony_zval_info()
--------------------
-
-- exposes zval_hash/refcounts, allowing e.g. efficient exploration of arbitrary structures in PHP,
-- does work with references, preventing memory copying.
-
-Its behavior is about the same as:
-
-```php
-<?php
-
-function symfony_zval_info($key, $array, $options = 0)
-{
-
-    // $options is currently not used, but could be in future version.
-
-    if (!array_key_exists($key, $array)) {

-    }
-

-        'type' => gettype($array[$key]),

-symfony_debug_backtrace()
--------------------------
-
-This function works like debug_backtrace(), except that it can fetch the full backtrace in case of fatal errors:
-
-```php
-function foo() { fatal(); }
-function bar() { foo(); }
-
-function sd() { var_dump(symfony_debug_backtrace()); }
-
-register_shutdown_function('sd');
-
-bar();
-
-/* Will output
-Fatal error: Call to undefined function fatal() in foo.php on line 42
-array(3) {
-  [0]=>
-  array(2) {
-    ["function"]=>
-    string(2) "sd"
-    ["args"]=>
-    array(0) {
-    }
-  }
-  [1]=>
-  array(4) {
-    ["file"]=>
-    string(7) "foo.php"
-    ["line"]=>
-    int(1)
-    ["function"]=>
-    string(3) "foo"
-    ["args"]=>
-    array(0) {
-    }
-  }
-  [2]=>
-  array(4) {

+
+A set of abstractions extracted out of the Symfony components.

+Can be used to build on semantics that the Symfony components proved useful - and
+that already have battle tested implementations.
+
+See https://github.com/symfony/contracts/blob/master/README.md for more information.

+
+4.1.0
+-----
+
+ * added support for invokable event listeners tagged with `kernel.event_listener` by default 
+ * The `TraceableEventDispatcher::getOrphanedEvents()` method has been added.
+ * The `TraceableEventDispatcherInterface` has been deprecated.
+
+4.0.0
+-----
+
+ * removed the `ContainerAwareEventDispatcher` class
+ * added the `reset()` method to the `TraceableEventDispatcherInterface`
+
 3.4.0

 CHANGELOG
 =========
 
+4.3.0
+-----
+
+ * renamed `Client` to `HttpKernelBrowser`
+ * `KernelInterface` doesn't extend `Serializable` anymore
+ * deprecated the `Kernel::serialize()` and `unserialize()` methods
+ * increased the priority of `Symfony\Component\HttpKernel\EventListener\AddRequestFormatsListener`
+ * made `Symfony\Component\HttpKernel\EventListener\LocaleListener` set the default locale early
+ * deprecated `TranslatorListener` in favor of `LocaleAwareListener`
+ * added the registration of all `LocaleAwareInterface` implementations into the `LocaleAwareListener`
+ * made `FileLinkFormatter` final and not implement `Serializable` anymore
+ * the base `DataCollector` doesn't implement `Serializable` anymore, you should
+   store all the serialized state in the data property instead
+ * `DumpDataCollector` has been marked as `final`
+ * added an event listener to prevent search engines from indexing applications in debug mode.
+ * renamed `FilterControllerArgumentsEvent` to `ControllerArgumentsEvent`
+ * renamed `FilterControllerEvent` to `ControllerEvent`
+ * renamed `FilterResponseEvent` to `ResponseEvent`
+ * renamed `GetResponseEvent` to `RequestEvent`
+ * renamed `GetResponseForControllerResultEvent` to `ViewEvent`
+ * renamed `GetResponseForExceptionEvent` to `ExceptionEvent`
+ * renamed `PostResponseEvent` to `TerminateEvent`
+ * added `HttpClientKernel` for handling requests with an `HttpClientInterface` instance
+ * added `trace_header` and `trace_level` configuration options to `HttpCache`
+
+4.2.0
+-----
+
+ * deprecated `KernelInterface::getRootDir()` and the `kernel.root_dir` parameter
+ * deprecated `KernelInterface::getName()` and the `kernel.name` parameter
+ * deprecated the first and second constructor argument of `ConfigDataCollector` 
+ * deprecated `ConfigDataCollector::getApplicationName()` 
+ * deprecated `ConfigDataCollector::getApplicationVersion()`
+
+4.1.0
+-----
+
+ * added orphaned events support to `EventDataCollector`
+ * `ExceptionListener` now logs exceptions at priority `0` (previously logged at `-128`)
+ * Added support for using `service::method` to reference controllers, making it consistent with other cases. It is recommended over the `service:action` syntax with a single colon, which will be deprecated in the future.
+ * Added the ability to profile individual argument value resolvers via the
+   `Symfony\Component\HttpKernel\Controller\ArgumentResolver\TraceableValueResolver`
+
+4.0.0
+-----
+
+ * removed the `DataCollector::varToString()` method, use `DataCollector::cloneVar()`
+   instead
+ * using the `DataCollector::cloneVar()` method requires the VarDumper component
+ * removed the `ValueExporter` class
+ * removed `ControllerResolverInterface::getArguments()`
+ * removed `TraceableControllerResolver::getArguments()`
+ * removed `ControllerResolver::getArguments()` and the ability to resolve arguments
+ * removed the `argument_resolver` service dependency from the `debug.controller_resolver`
+ * removed `LazyLoadingFragmentHandler::addRendererService()`
+ * removed `Psr6CacheClearer::addPool()`
+ * removed `Extension::addClassesToCompile()` and `Extension::getClassesToCompile()`
+ * removed `Kernel::loadClassCache()`, `Kernel::doLoadClassCache()`, `Kernel::setClassCache()`,
+   and `Kernel::getEnvParameters()`
+ * support for the `X-Status-Code` when handling exceptions in the `HttpKernel`
+   has been dropped, use the `HttpKernel::allowCustomResponseCode()` method
+   instead
+ * removed convention-based commands registration
+ * removed the `ChainCacheClearer::add()` method
+ * removed the `CacheaWarmerAggregate::add()` and `setWarmers()` methods
+ * made `CacheWarmerAggregate` and `ChainCacheClearer` classes final
+
 3.4.0

+             *    the data could be missing the next request because it might not be saved the moment
+             *    the new request is processed.
+             *  * A locking save handler (e.g. the native 'files') circumvents concurrency problems like

+             *    we ensure the session is not blocked longer than needed.
+             *  * When regenerating the session ID no locking is involved in PHPs session design. See
+             *    https://bugs.php.net/61470 for a discussion. So in this case, the session must
+             *    be saved anyway before sending the headers with the new session ID. Otherwise session
+             *    data could get lost again for concurrent requests with the new ID. One result could be
+             *    that you get logged out after just logging in.
+             *
+             * This listener should be executed as one of the last listeners, so that previous listeners
+             * can still operate on the open session. This prevents the overhead of restarting it.
+             * Listeners after closing the session can still work with the session as usual because
+             * Symfonys session implementation starts the session on demand. So writing to it after
+             * it is saved will just restart it.

- * Saves the session, in case it is still open, before sending the response/headers.
- *
- * This ensures several things in case the developer did not save the session explicitly:
- *
- *  * If a session save handler without locking is used, it ensures the data is available
- *    on the next request, e.g. after a redirect. PHPs auto-save at script end via
- *    session_register_shutdown is executed after fastcgi_finish_request. So in this case
- *    the data could be missing the next request because it might not be saved the moment
- *    the new request is processed.
- *  * A locking save handler (e.g. the native 'files') circumvents concurrency problems like
- *    the one above. But by saving the session before long-running things in the terminate event,
- *    we ensure the session is not blocked longer than needed.
- *  * When regenerating the session ID no locking is involved in PHPs session design. See
- *    https://bugs.php.net/bug.php?id=61470 for a discussion. So in this case, the session must
- *    be saved anyway before sending the headers with the new session ID. Otherwise session
- *    data could get lost again for concurrent requests with the new ID. One result could be
- *    that you get logged out after just logging in.
- *
- * This listener should be executed as one of the last listeners, so that previous listeners
- * can still operate on the open session. This prevents the overhead of restarting it.
- * Listeners after closing the session can still work with the session as usual because
- * Symfonys session implementation starts the session on demand. So writing to it after
- * it is saved will just restart it.

+ISO-2022-JPは、インターネット上(特に電子メール)などで使われる日本の文字用の文字符号化方式。ISO/IEC 2022のエスケープシーケンスを利用して文字集合を切り替える7ビットのコードであることを特徴とする (アナウンス機能のエスケープシーケンスは省略される)。俗に「JISコード」と呼ばれることもある。
+
+概要
+日本語表記への利用が想定されている文字コードであり、日本語の利用されるネットワークにおいて、日本の規格を応用したものである。また文字集合としては、日本語で用いられる漢字、ひらがな、カタカナはもちろん、ラテン文字、ギリシア文字、キリル文字なども含んでおり、学術や産業の分野での利用も考慮たものとなっている。規格名に、ISOの日本語の言語コードであるjaではなく、国・地域名コードのJPが示されているゆえんである。
+文字集合としてJIS X 0201のC0集合（制御文字）、JIS X 0201のラテン文字集合、ISO 646の国際基準版図形文字、JIS X 0208の1978年版（JIS C 6226-1978）と1983年および1990年版が利用できる。JIS X 0201の片仮名文字集合は利用できない。1986年以降、日本の電子メールで用いられてきたJUNETコードを、村井純・Mark Crispin・Erik van der Poelが1993年にRFC化したもの(RFC 1468)。後にJIS X 0208:1997の附属書2としてJISに規定された。MIMEにおける文字符号化方式の識別用の名前として IANA に登録されている。
+なお、符号化の仕様についてはISO/IEC 2022#ISO-2022-JPも参照。
+
+ISO-2022-JPと非標準的拡張使用
+「JISコード」（または「ISO-2022-JP」）というコード名の規定下では、その仕様通りの使用が求められる。しかし、Windows OS上では、実際にはCP932コード (MicrosoftによるShift JISを拡張した亜種。ISO-2022-JP規定外文字が追加されている。）による独自拡張（の文字）を断りなく使うアプリケーションが多い。この例としてInternet ExplorerやOutlook Expressがある。また、EmEditor、秀丸エディタやThunderbirdのようなMicrosoft社以外のWindowsアプリケーションでも同様の場合がある。この場合、ISO-2022-JPの範囲外の文字を使ってしまうと、異なる製品間では未定義不明文字として認識されるか、もしくは文字化けを起こす原因となる。そのため、Windows用の電子メールクライアントであっても独自拡張の文字を使用すると警告を出したり、あえて使えないように制限しているものも存在する。さらにはISO-2022-JPの範囲内であってもCP932は非標準文字（FULLWIDTH TILDE等）を持つので文字化けの原因になり得る。
+また、符号化方式名をISO-2022-JPとしているのに、文字集合としてはJIS X 0212 (いわゆる補助漢字) やJIS X 0201の片仮名文字集合 (いわゆる半角カナ) をも符号化している例があるが、ISO-2022-JPではこれらの文字を許容していない。これらの符号化は独自拡張の実装であり、中にはISO/IEC 2022の仕様に準拠すらしていないものもある[2]。従って受信側の電子メールクライアントがこれらの独自拡張に対応していない場合、その文字あるいはその文字を含む行、時にはテキスト全体が文字化けすることがある。

-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`.

+Symfony Polyfill / Php72
+========================
+
+This component provides functions added to PHP 7.2 core:
+
+- [`spl_object_id`](https://php.net/spl_object_id)
+- [`stream_isatty`](https://php.net/stream_isatty)
+
+On Windows only:
+
+- [`sapi_windows_vt100_support`](https://php.net/sapi_windows_vt100_support)
+
+Moved to core since 7.2 (was in the optional XML extension earlier):
+
+- [`utf8_encode`](https://php.net/utf8_encode)
+- [`utf8_decode`](https://php.net/utf8_decode)
+
+Also, it provides a constant added to PHP 7.2:
+- [`PHP_OS_FAMILY`](http://php.net/manual/en/reserved.constants.php#constant.php-os-family)
+
+More information can be found in the
+[main Polyfill README](https://github.com/symfony/polyfill/blob/master/README.md).

+Most of the time though, a tag is not needed:
+
+* If your tag generates some output, use a **function** instead.
+
+* If your tag modifies some content and returns it, use a **filter** instead.

+  text to HTML, create a ``markdown`` filter instead:

+  .. code-block:: twig

+
+  .. code-block:: twig
+
+      {% apply markdown %}
+      Title
+      =====
+
+      Much better than creating a tag as you can **compose** filters.
+      {% endapply %}
+
+ .. note::
+
+      The ``apply`` tag was introduced in Twig 1.40; use the ``filter`` tag with
+      previous versions.
+
+* If your tag does not output anything, but only exists because of a side
+  effect, create a **function** that returns nothing and call it via the
+  :doc:`filter <tags/do>` tag.
+

-    }
-
-    $twig = new Twig_Environment($loader);

-Here, we have overloaded the built-in ``date`` filter with a custom one.

+
+The ``filter`` filter filters elements of a sequence or a mapping using an arrow

+
+.. code-block:: twig
+
+    {% set sizes = [34, 36, 38, 40, 42] %}
+
+    {{ sizes|filter(v => v > 38)|join(', ') }}
+    {# output 40, 42 #}
+

+
+.. code-block:: twig
+
+    {% for v in sizes|filter(v => v > 38) -%}
+        {{ v }}
+    {% endfor %}
+    {# output 40 42 #}
+

+
+.. code-block:: twig
+
+    {% set sizes = {
+        xs: 34,
+        s:  36,

+        {{ k }} = {{ v }}
+    {% endfor %}
+    {# output l = 40 xl = 42 #}

+``spaceless``
+=============
+
+.. versionadded:: 1.38
+
+    The ``spaceless`` filter was added in Twig 1.38.
+
+Use the ``spaceless`` filter to remove whitespace *between HTML tags*, not
+whitespace within HTML tags or whitespace in plain text:
+
+.. code-block:: twig
+
+    {{
+        "<div>
+            <strong>foo</strong>
+        </div>
+        "|spaceless }}
+
+    {# output will be <div><strong>foo</strong></div> #}
+
+You can combine ``spaceless`` with the ``apply`` tag to apply the transformation
+on large amounts of HTML:
+
+.. code-block:: twig
+
+    {% apply spaceless %}
+        <div>
+            <strong>foo</strong>
+        </div>
+    {% endapply %}
+
+    {# output will be <div><strong>foo</strong></div> #}
+
+.. note::
+
+    The ``apply`` tag was introduced in Twig 1.40; use the ``filter`` tag with
+    previous versions.
+
+This tag is not meant to "optimize" the size of the generated HTML content but
+merely to avoid extra whitespace between HTML tags to avoid browser rendering
+quirks under some circumstances.
+
+.. caution::
+
+    As the filter uses a regular expression behind the scenes, its performance
+    is directly related to the text size you are working on (remember that
+    filters are executed at runtime).
+
+.. tip::
+
+    If you want to optimize the size of the generated HTML content, gzip
+    compress the output instead.
+
+.. tip::
+
+    If you want to create a tag that actually removes all extra whitespace in
+    an HTML string, be warned that this is not as easy as it seems to be
+    (think of ``textarea`` or ``pre`` tags for instance). Using a third-party
+    library like Tidy is probably a better idea.
+
+.. tip::
+
+    For more information on whitespace control, read the
+    :ref:`dedicated section <templates-whitespace-control>` of the documentation and learn how
+    you can also use the whitespace control modifier on your tags.

 The lexer tokenizes a template source code into a token stream (each token is

-* ``Twig_Token::VAR_START_TYPE``, ``Twig_Token::VAR_END_TYPE``: Delimiters for variables (``{{ }}``)
-* ``Twig_Token::TEXT_TYPE``: A text outside an expression;
-* ``Twig_Token::NAME_TYPE``: A name in an expression;
-* ``Twig_Token::NUMBER_TYPE``: A number in an expression;
-* ``Twig_Token::STRING_TYPE``: A string in an expression;
-* ``Twig_Token::OPERATOR_TYPE``: An operator;
-* ``Twig_Token::PUNCTUATION_TYPE``: A punctuation sign;

 ``import``
 ==========
 
-Twig supports putting often used code into :doc:`macros<../tags/macro>`. These
-macros can go into different templates and get imported from there.
-
-There are two ways to import templates. You can import the complete template
-into a variable or request specific macros from it.
-
-Imagine we have a helper module that renders forms (called ``forms.html``):
-
-.. code-block:: jinja
-
-    {% macro input(name, value, type, size) %}
-        <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
-    {% endmacro %}
-
-    {% macro textarea(name, value, rows, cols) %}
-        <textarea name="{{ name }}" rows="{{ rows|default(10) }}" cols="{{ cols|default(40) }}">{{ value|e }}</textarea>
-    {% endmacro %}
-
-The easiest and most flexible is importing the whole module into a variable.
-That way you can access the attributes:
-
-.. code-block:: jinja
-
-    {% import 'forms.html' as forms %}
-
-    <dl>
-        <dt>Username</dt>
-        <dd>{{ forms.input('username') }}</dd>

-        <dd>{{ forms.input('password', null, 'password') }}</dd>
-    </dl>
-    <p>{{ forms.textarea('comment') }}</p>
-
-Alternatively you can import names from the template into the current
-namespace:
-
-.. code-block:: jinja
-
-    {% from 'forms.html' import input as input_field, textarea %}
-
-    <dl>

+    Importing macros using ``import`` or ``from`` is **local** to the current

-Macros can be defined in any template, and need to be "imported" via the
-:doc:`import<tags/import>` tag before being used:
-
-.. code-block:: jinja
-
-    {% import "forms.html" as forms %}
-
-    <p>{{ forms.input('username') }}</p>
-
-Alternatively, you can import individual macro names from a template into the
-current namespace via the :doc:`from<tags/from>` tag and optionally alias them:
-
-.. code-block:: jinja
-
-    {% from 'forms.html' import input as input_field %}
-
-    <dl>
-        <dt>Username</dt>
-        <dd>{{ input_field('username') }}</dd>
-        <dt>Password</dt>
-        <dd>{{ input_field('password', '', 'password') }}</dd>
-    </dl>
-
-A default value can also be defined for macro arguments when not provided in a
-macro call:
-
-.. code-block:: jinja
-
-    {% macro input(name, value = "", type = "text", size = 20) %}
-        <input type="{{ type }}" name="{{ name }}" value="{{ value|e }}" size="{{ size }}" />
-    {% endmacro %}
-
-If extra positional arguments are passed to a macro call, they end up in the
-special ``varargs`` variable as a list of values.
+Macros are comparable with functions in regular programming languages. They are
+useful to reuse HTML fragments to not repeat yourself. They are described in the
+:doc:`macro<tags/macro>` tag documentation.

+The first newline after a template tag is removed automatically (like in PHP).
 Whitespace is not further modified by the template engine, so each whitespace
 (spaces, tabs, newlines etc.) is returned unchanged.
 
-Use the ``spaceless`` tag to remove whitespace *between HTML tags*:
+You can also control whitespace on a per tag level. By using the whitespace
+control modifiers on your tags, you can trim leading and or trailing whitespace.
 
-.. code-block:: jinja
+Twig supports two modifiers:
 
-    {% spaceless %}
-        <div>
-            <strong>foo bar</strong>
-        </div>
-    {% endspaceless %}

+  (including newlines);

+* *Line whitespace trimming* via the ``~`` modifier: Removes all whitespace
+  (excluding newlines). Using this modifier on the right disables the default
+  removal of the first newline inherited from PHP.
 
-In addition to the spaceless tag you can also control whitespace on a per tag
-level. By using the whitespace control modifier on your tags, you can trim
-leading and or trailing whitespace:
+The modifiers can be used on either side of the tags like in ``{%-`` or ``-%}``
+and they consume all whitespace for that side of the tag. It is possible to use
+the modifiers on one side of a tag or on both sides:
 
-.. code-block:: jinja
+.. code-block:: twig
 
     {% set value = 'no spaces' %}

-

-The above sample shows the default whitespace control modifier, and how you can
-use it to remove whitespace around tags. Trimming space will consume all whitespace
-for that side of the tag.  It is possible to use whitespace trimming on one side
-of a tag:

+    {# outputs '<li>\nno spaces    </li>' #}
 
-    {# outputs '<li>no spaces    </li>' #}
+.. tip::
+
+    In addition to the whitespace modifiers, Twig also has a ``spaceless`` filter
+    that removes whitespace **between HTML tags**:
+
+    .. code-block:: twig
+
+        {% apply spaceless %}
+            <div>
+                <strong>foo bar</strong>
+            </div>
+        {% endapply %}
+
+        {# output will be <div><strong>foo bar</strong></div> #}
+
+    Note that the ``apply`` tag was introduced in Twig 1.40; use the ``filter``
+    tag with previous versions.

-/**
- * Twig base exception.
- *
- * This exception class and its children must only be used when
- * an error occurs during the loading of a template, when a syntax error
- * is detected in a template, or when rendering a template. Other
- * errors must use regular PHP exception classes (like when the template
- * cache directory is not writable for instance).
- *
- * To help debugging template issues, this class tracks the original template
- * name and line where the error occurred.
- *
- * Whenever possible, you must set these information (original template name
- * and line number) yourself by passing them to the constructor. If some or all
- * these information are not available from where you throw the exception, then
- * this class will guess them automatically (when the line number is set to -1
- * and/or the name is set to null). As this is a costly operation, this
- * can be disabled by passing false for both the name and the line number
- * when creating a new instance of this class.
