Release Notes

nodeca/js-yaml (js-yaml)

v4.2.0

Compare Source

Added
  • Added docs/safety.md with notes about processing untrusted YAML.
  • Added maxDepth (100) loader option. Not a problem, but gives a better
    exception instead of RangeError on stack overflow.
  • Added maxMergeSeqLength (20) loader option. Not a problem after merge fix,
    but an additional restriction for safety.
  • Added sourcemaps to dist/ builds.
Changed
  • Stop resolving numbers with underscores as numeric scalars, #​627.
  • Switched dev toolchains to Vite / neostandard.
  • Updated demo.
  • Reorganized tests.
  • dist/ files are no longer kept in the repository.
Fixed
  • Fix parsing of properties on the first implicit block mapping key, #​62.
  • Fix trailing whitespace handling when folding flow scalar lines, #​307.
  • Reject top-level block scalars without content indentation, #​280.
  • Ensure numbers survive round-trip, #​737.
  • Fix test coverage for issue #​221.
  • Fix flow scalar trailing whitespace folding, #​307.
  • Fix digits in YAML named tag handles.
Security
  • Fix potential DoS via quadratic complexity in merge - deduplicate repeated
    elements (makes sense for malformed files > 10K).

v4.1.1

Compare Source

v4.1.0

Compare Source

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).

v4.0.0

Compare Source

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.
Fixed
  • Astral characters are no longer encoded by dump(), #​587.
  • "duplicate mapping key" exception now points at the correct column, #​452.
  • Extra commas in flow collections (e.g. [foo,,bar]) now throw an exception
    instead of producing null, #​321.
  • __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.
  • Throw an error if block sequence/mapping indent contains a tab, #​80.
