  • v4.0.0 Changes

    January 03, 2021

    🔄 Changed

    • Check [migration guide](migrate_v3_to_v4.md) 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 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.

    • 👻 "duplicate mapping key" exception now points at the correct column, #452.

    • __proto__ key no longer overrides object prototype, #164.
    • ✂ Removed bower.json.
    • 🏷 Tags are now url-decoded in load() and url-encoded in dump() (previously usage of custom non-ascii tags may have led to invalid YAML that can't be parsed).
    • Anchors now work correctly with empty nodes, #301.
    • 🛠 Fix incorrect parsing of invalid block mapping syntax, #418.
