+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.

+CHANGELOG
+=========
+
+6.1
+---
+
+ * Make `start()` and `stop()` methods public on `SmtpTransport`
+ * Improve extensibility of `EsmtpTransport`
+
+6.0
+---
+
+ * The `HttpTransportException` class takes a string at first argument
+
+5.4
+---
+
+ * Enable the mailer to operate on any PSR-14-compatible event dispatcher
+
+5.3
+---
+
+ * added the `mailer` monolog channel and set it on all transport definitions
+
+5.2.0
+-----
+
+ * added `NativeTransportFactory` to configure a transport based on php.ini settings
+ * added `local_domain`, `restart_threshold`, `restart_threshold_sleep` and `ping_threshold` options for `smtp`
+ * added `command` option for `sendmail`
+
+4.4.0
+-----
+
+ * [BC BREAK] changed the `NullTransport` DSN from `smtp://null` to `null://null`
+ * [BC BREAK] renamed `SmtpEnvelope` to `Envelope`, renamed `DelayedSmtpEnvelope` to
+   `DelayedEnvelope`
+ * [BC BREAK] changed the syntax for failover and roundrobin DSNs
+
+   Before:
+
+   dummy://a || dummy://b (for failover)
+   dummy://a && dummy://b (for roundrobin)
+
+   After:
+
+   failover(dummy://a dummy://b)
+   roundrobin(dummy://a dummy://b)
+
+ * added support for multiple transports on a `Mailer` instance
+ * [BC BREAK] removed the `auth_mode` DSN option (it is now always determined automatically)
+ * STARTTLS cannot be enabled anymore (it is used automatically if TLS is disabled and the server supports STARTTLS)
+ * [BC BREAK] Removed the `encryption` DSN option (use `smtps` instead)
+ * Added support for the `smtps` protocol (does the same as using `smtp` and port `465`)
+ * Added PHPUnit constraints
+ * Added `MessageDataCollector`
+ * Added `MessageEvents` and `MessageLoggerListener` to allow collecting sent emails
+ * [BC BREAK] `TransportInterface` has a new `__toString()` method
+ * [BC BREAK] Classes `AbstractApiTransport` and `AbstractHttpTransport` moved under `Transport` sub-namespace.
+ * [BC BREAK] Transports depend on `Symfony\Contracts\EventDispatcher\EventDispatcherInterface`
+   instead of `Symfony\Component\EventDispatcher\EventDispatcherInterface`.
+ * Added possibility to register custom transport for dsn by implementing
+   `Symfony\Component\Mailer\Transport\TransportFactoryInterface` and tagging with `mailer.transport_factory` tag in DI.
+ * Added `Symfony\Component\Mailer\Test\TransportFactoryTestCase` to ease testing custom transport factories.
+ * Added `SentMessage::getDebug()` and `TransportExceptionInterface::getDebug` to help debugging
+ * Made `MessageEvent` final
+ * add DSN parameter `verify_peer` to disable TLS peer verification for SMTP transport
+
+4.3.0
+-----
+
+ * Added the component.
