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.

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:

  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.
