CHANGELOG
=========
+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
