    After:

    Yaml::parse('0o72');

  • 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.

4.2.0

  • added support for multiple files or directories in LintCommand

  • support for the !!php/object tag has been dropped, use the !php/object tag instead

  • 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.

    Yaml::parse('!foo bar', Yaml::PARSE_CUSTOM_TAGS);

  • 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.

  • 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.

true: boolean true
2.0: float key
YAML;
