# changelog

#### Version 0.5.3 (2019-12-28)

* Fixed: base64 encoded source maps now correctly decodes as utf-8. Previously, non-ASCII characters could end up garbled. Thanks to ZHAO Jinxiang (@xiaoxiangmoe)! (Note: This fix does not work in old evironments not supporting both `TextDecoder` and `Uint8Array`.)
* Improved: Reduced size of the npm package.

#### Version 0.5.2 (2018-05-10)

* Improved: Updated the version range of `atob` to disallow depending on `2.0.3` which as a [security vulnerability](https://snyk.io/test/npm/atob/2.0.3?severity=high\&severity=medium\&severity=low).

#### Version 0.5.1 (2017-10-21)

* Fixed: URLs are now decoded before being passed to `read` in Node.js. This allows reading files with spaces, for example.
* Fixed: Missing or empty `sources` fields (such as `sources: []`) in source maps are now handled. Previously, such source maps would cause crashes or callbacks never bing called. Now, an empty result is produced:

  ```js
  sourcesResolved: [],
  sourcesContent: []
  ```

#### Version 0.5.0 (2016-02-28)

* Improved: Errors now have a `sourceMapData` property that contain as much as possible of the intended result of the function up until the error occurred.
* Changed: `resolveSources` and `resolve`, as well as their `*Sync` alternatives, no longer fail when one single source fails to be fetched. Instead, the `sourcesContent` array in the result object will contain error objects for all failed sources, and strings otherwise. (Backwards-incompatible change.)

#### Version 0.4.0 (2015-08-29)

* Removed: The `ignoreSourceRoot` option of `resolveSources`. It has been replaced with `sourceRoot: false`. (Backwards-incompatible change.)
* Added: The `sourceRoot` option of `resolveSources`. It not only allows to ignore the source root, it also lets you replace it.
* Added: The `parseMapToJSON` method.
* Added: The `resolve` method now accepts `null, mapUrl, ...` as arguments, in addition to the existing signature, which will read `mapUrl` instead of looking for a sourceMappingURL in the code.

#### Version 0.3.1 (2014-08-16)

* Improved: Updated the source-map-url dependency to 0.3.0.

#### Version 0.3.0 (2014-07-02)

* Removed: Argument checking. It’s not worth it. (Possibly backwards-incompatible change.)
* Added: The `sourceRoot` property of source maps may now be ignored, which can be useful when resolving sources outside of the browser.
* Added: It is now possible to resolve only the URLs of sources, without reading them.

#### Version 0.2.0 (2014-06-22)

* Changed: The result of `resolveSources` is now an object, not an array. The old result array is available in the `sourcesContent` property. (Backwards-incompatible change.)
* Changed: `sources` has been renamed to `sourcesContent` in the result object of `resolve`. (Backwards-incompatible change.)
* Added: `resolveSources` now also returns all sources fully resolved, in the `sourcesResolved` property.
* Added: The result object of `resolve` now contains the `sourcesResolved` property from `resolveSources`.

#### Version 0.1.4 (2014-06-16)

* Fixed: `sourcesContent` was mis-typed as `sourceContents`, which meant that the `sourcesContent` property of source maps never was used when resolving sources.

#### Version 0.1.3 (2014-05-06)

* Only documentation and meta-data changes.

#### Version 0.1.2 (2014-03-23)

* Improved: Source maps starting with `)]}'` are now parsed correctly. The spec allows source maps to start with that character sequence to prevent XSSI attacks.

#### Version 0.1.1 (2014-03-06)

* Improved: Make sourceRoot resolving more sensible.

  A source root such as `/scripts/subdir` is now treated as `/scripts/subdir/` — that is, as a directory called “subdir”, not a file called “subdir”. Pointing to a file as source root does not makes sense.

#### Version 0.1.0 (2014-03-03)

* Initial release.
