+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
+=========
+
+4.4.0
+-----
+
+ * Added support for parsing the inline notation spanning multiple lines.
+ * Added support to dump `null` as `~` by using the `Yaml::DUMP_NULL_AS_TILDE` flag.
+ * deprecated accepting STDIN implicitly when using the `lint:yaml` command, use `lint:yaml -` (append a dash) instead to make it explicit.
+
+4.3.0
+-----
+
+ * Using a mapping inside a multi-line string is deprecated and will throw a `ParseException` in 5.0.
+
+4.2.0
+-----
+
+ * added support for multiple files or directories in `LintCommand`
+
+4.0.0
+-----
+
+ * The behavior of the non-specific tag `!` is changed and now forces
+   non-evaluating your values.
+ * complex mappings will throw a `ParseException`
+ * support for the comma as a group separator for floats has been dropped, use
+   the underscore instead
+ * support for the `!!php/object` tag has been dropped, use the `!php/object`
+   tag instead
+ * duplicate mapping keys throw a `ParseException`
+ * non-string mapping keys throw a `ParseException`, use the `Yaml::PARSE_KEYS_AS_STRINGS`
+   flag to cast them to strings
+ * `%` at the beginning of an unquoted string throw a `ParseException`
+ * mappings with a colon (`:`) that is not followed by a whitespace throw a
+   `ParseException`
+ * the `Dumper::setIndentation()` method has been removed
+ * being able to pass boolean options to the `Yaml::parse()`, `Yaml::dump()`,
+   `Parser::parse()`, and `Dumper::dump()` methods to configure the behavior of
+   the parser and dumper is no longer supported, pass bitmask flags instead
+ * the constructor arguments of the `Parser` class have been removed
+ * the `Inline` class is internal and no longer part of the BC promise
+ * removed support for the `!str` tag, use the `!!str` tag instead
+ * added support for tagged scalars.
+
+   ```yml
+   Yaml::parse('!foo bar', Yaml::PARSE_CUSTOM_TAGS);
+   // returns TaggedValue('foo', 'bar');
+   ```
+
+3.4.0
+-----
+
+ * added support for parsing YAML files using the `Yaml::parseFile()` or `Parser::parseFile()` method
+
+ * the `Dumper`, `Parser`, and `Yaml` classes are marked as final
+
+ * Deprecated the `!php/object:` tag which will be replaced by the
+   `!php/object` tag (without the colon) in 4.0.
+
+ * Deprecated the `!php/const:` tag which will be replaced by the
+   `!php/const` tag (without the colon) in 4.0.
+
+ * Support for the `!str` tag is deprecated, use the `!!str` tag instead.
+
+ * Deprecated using the non-specific tag `!` as its behavior will change in 4.0.
+   It will force non-evaluating your values in 4.0. Use plain integers or `!!float` instead.
+
+3.3.0
+-----
+
+ * Starting an unquoted string with a question mark followed by a space is
+   deprecated and will throw a `ParseException` in Symfony 4.0.
+
+ * Deprecated support for implicitly parsing non-string mapping keys as strings.
+   Mapping keys that are no strings will lead to a `ParseException` in Symfony
+   4.0. Use quotes to opt-in for keys to be parsed as strings.
+
+   Before:
+
+   ```php
+   $yaml = <<<YAML
+   null: null key
+   true: boolean true
+   2.0: float key
+   YAML;
+
+   Yaml::parse($yaml);
+   ```
+
+   After:

+
+   $yaml = <<<YAML
+   "null": null key
+   "true": boolean true
+   "2.0": float key
+   YAML;
+
+   Yaml::parse($yaml);
+   ```
+
+ * Omitted mapping values will be parsed as `null`.
+
+ * Omitting the key of a mapping is deprecated and will throw a `ParseException` in Symfony 4.0.
+
+ * Added support for dumping empty PHP arrays as YAML sequences:
+
+   ```php
+   Yaml::dump([], 0, 0, Yaml::DUMP_EMPTY_ARRAY_AS_SEQUENCE);
+   ```
+
+3.2.0
+-----
+
+ * Mappings with a colon (`:`) that is not followed by a whitespace are deprecated
+   when the mapping key is not quoted and will lead to a `ParseException` in
+   Symfony 4.0 (e.g. `foo:bar` must be `foo: bar`).
+
+ * Added support for parsing PHP constants:
+
+   ```php
+   Yaml::parse('!php/const:PHP_INT_MAX', Yaml::PARSE_CONSTANT);
+   ```
+
+ * Support for silently ignoring duplicate mapping keys in YAML has been
+   deprecated and will lead to a `ParseException` in Symfony 4.0.
+
+3.1.0
+-----
+
+ * Added support to dump `stdClass` and `ArrayAccess` objects as YAML mappings
+   through the `Yaml::DUMP_OBJECT_AS_MAP` flag.
+
+ * Strings that are not UTF-8 encoded will be dumped as base64 encoded binary
+   data.
+
+ * Added support for dumping multi line strings as literal blocks.
+
+ * Added support for parsing base64 encoded binary data when they are tagged
+   with the `!!binary` tag.
+
+ * Added support for parsing timestamps as `\DateTime` objects:
+
+   ```php
+   Yaml::parse('2001-12-15 21:59:43.10 -5', Yaml::PARSE_DATETIME);
+   ```
+
+ * `\DateTime` and `\DateTimeImmutable` objects are dumped as YAML timestamps.
+
+ * Deprecated usage of `%` at the beginning of an unquoted string.
+
+ * Added support for customizing the YAML parser behavior through an optional bit field:
+
+   ```php
+   Yaml::parse('{ "foo": "bar", "fiz": "cat" }', Yaml::PARSE_EXCEPTION_ON_INVALID_TYPE | Yaml::PARSE_OBJECT | Yaml::PARSE_OBJECT_FOR_MAP);
+   ```
+
+ * Added support for customizing the dumped YAML string through an optional bit field:
+
+   ```php
+   Yaml::dump(['foo' => new A(), 'bar' => 1], 0, 0, Yaml::DUMP_EXCEPTION_ON_INVALID_TYPE | Yaml::DUMP_OBJECT);
+   ```
+
+3.0.0
+-----
+
+ * Yaml::parse() now throws an exception when a blackslash is not escaped
+   in double-quoted strings
+
+2.8.0
+-----
+
+ * Deprecated usage of a colon in an unquoted mapping value
+ * Deprecated usage of @, \`, | and > at the beginning of an unquoted string
+ * When surrounding strings with double-quotes, you must now escape `\` characters. Not
+   escaping those characters (when surrounded by double-quotes) is deprecated.
