+CHANGELOG
+=========
+
+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:
+
+   ```php
+
+   $yaml = <<<YAML
+   "null": null key
+   "true": boolean true
+   "2.0": float key
+   YAML;
+
+   Yaml::parse($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(array('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.
+
+   Before:
+
+   ```yml
+   class: "Foo\Var"
+   ```
+
+   After:
+
+   ```yml
+   class: "Foo\\Var"
+   ```
+
+2.1.0
+-----
+
+ * Yaml::parse() does not evaluate loaded files as PHP files by default
+   anymore (call Yaml::enablePhpParsing() to get back the old behavior)
