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.
