| ## [4.0.0] - 2021-01-03 | ||
| ### 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](https://github.com/nodeca/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. | ||

| Browser support was done mostly for the online demo. If you find any errors - feel | ||
| free to send pull requests with fixes. Also note, that IE and other old browsers | ||
| needs [es5-shims](https://github.com/kriskowal/es5-shim) to operate. | ||
| Notes: | ||
| 1. We have no resources to support browserified version. Don't expect it to be | ||
| well tested. Don't expect fast fixes if something goes wrong there. | ||
| 2. `!!js/function` in browser bundle will not work by default. If you really need | ||
| it - load `esprima` parser first (via amd or directly). | ||
| 3. `!!bin` in browser will return `Array`, because browsers do not support | ||
