6.2
---
* Add support for `!php/enum` and `!php/enum *->value`
* Deprecate the `!php/const:` tag in key which will be replaced by the `!php/const` tag (without the colon) since 3.4
6.1
---
* In cases where it will likely improve readability, strings containing single quotes will be double-quoted
5.4
---
* Add new `lint:yaml dirname --exclude=/dirname/foo.yaml --exclude=/dirname/bar.yaml`
option to exclude one or more specific files from multiple file list

when running the YAML linter command in a Github Action environment.
5.1.0
-----
* Added support for parsing numbers prefixed with `0o` as octal numbers.
* Deprecated support for parsing numbers starting with `0` as octal numbers. They will be parsed as strings as of Symfony 6.0. Prefix numbers with `0o`
so that they are parsed as octal numbers.
Before:
```yaml
Yaml::parse('072');
```
After:
```yaml
Yaml::parse('0o72');
```
* Added `yaml-lint` binary.
* Deprecated using the `!php/object` and `!php/const` tags without a value.
5.0.0
-----
* Removed support for mappings inside multi-line strings.
* removed support for implicit STDIN usage in the `lint:yaml` command, use `lint:yaml -` (append a dash) instead to make it explicit.
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:
```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(['foo' => new A(), 'bar' => 1], 0, 0, Yaml::DUMP_EXCEPTION_ON_INVALID_TYPE | Yaml::DUMP_OBJECT);
```

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)
