Bumps js-yaml from 3.14.1 to 4.1.1.

Changelog

Sourced from js-yaml's changelog.

[4.1.1] - 2025-11-12

Security

  • Fix prototype pollution issue in yaml merge (<<) operator.

[4.1.0] - 2021-04-15

Added

  • Types are now exported as yaml.types.XXX.
  • Every type now has options property with original arguments kept as they were (see yaml.types.int.options as an example).

Changed

  • Schema.extend() now keeps old type order in case of conflicts (e.g. Schema.extend([ a, b, c ]).extend([ b, a, d ]) is now ordered as abcd instead of cbad).

[4.0.0] - 2021-01-03

Changed

  • Check migration guide to see details for all breaking changes.
  • Breaking: "unsafe" tags !!js/function, !!js/regexp, !!js/undefined are moved to js-yaml-js-types package.
  • Breaking: removed safe* functions. Use load, loadAll, dump instead which are all now safe by default.
  • yaml.DEFAULT_SAFE_SCHEMA and yaml.DEFAULT_FULL_SCHEMA are removed, use yaml.DEFAULT_SCHEMA instead.
  • yaml.Schema.create(schema, tags) is removed, use schema.extend(tags) instead.
  • !!binary now always mapped to Uint8Array on load.
  • Reduced nesting of /lib folder.
  • Parse numbers according to YAML 1.2 instead of YAML 1.1 (01234 is now decimal, 0o1234 is octal, 1:23 is parsed as string instead of base60).
  • dump() no longer quotes :, [, ], (, ) except when necessary, #470, #557.
  • Line and column in exceptions are now formatted as (X:Y) instead of at line X, column Y (also present in compact format), #332.
  • Code snippet created in exceptions now contains multiple lines with line numbers.
  • dump() now serializes undefined as null in collections and removes keys with undefined in mappings, #571.
  • dump() with skipInvalid=true now serializes invalid items in collections as null.
  • Custom tags starting with ! are now dumped as !tag instead of !<!tag>, #576.
  • Custom tags starting with tag:yaml.org,2002: are now shorthanded using !!, #258.

Added

  • Added .mjs (es modules) support.
  • Added quotingType and forceQuotes options for dumper to configure string literal style, #290, #529.
  • Added styles: { '!!null': 'empty' } option for dumper (serializes { foo: null } as "foo: "), #570.
  • Added replacer option (similar to option in JSON.stringify), #339.
  • Custom Tag can now handle all tags or multiple tags with the same prefix, #385.
