+### 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.

+
+Installation
+============
+
+- `npm install source-map-resolve`
+- `bower install source-map-resolve`
+- `component install lydell/source-map-resolve`
+
+Works with CommonJS, AMD and browser globals, through UMD.
+
+Note: This module requires `setImmediate` and `atob`.
+Use polyfills if needed, such as:
+
+- <https://github.com/NobleJS/setImmediate>
+- <https://github.com/davidchambers/Base64.js>
+
+
+Usage
+=====
+
+### `sourceMapResolve.resolveSourceMap(code, codeUrl, read, callback)` ###
+
+- `code` is a string of code that may or may not contain a sourceMappingURL
+  comment. Such a comment is used to resolve the source map.
+- `codeUrl` is the url to the file containing `code`. If the sourceMappingURL
+  is relative, it is resolved against `codeUrl`.
+- `read(url, callback)` is a function that reads `url` and responds using
+  `callback(error, content)`. In Node.js you might want to use `fs.readFile`,
+  while in the browser you might want to use an asynchronus `XMLHttpRequest`.
+- `callback(error, result)` is a function that is invoked with either an error
+  or `null` and the result.
+
+The result is an object with the following properties:
+
+- `map`: The source map for `code`, as an object (not a string).
+- `url`: The url to the source map. If the source map came from a data uri,
+  this property is `null`, since then there is no url to it.
+- `sourcesRelativeTo`: The url that the sources of the source map are relative
+  to. Since the sources are relative to the source map, and the url to the
+  source map is provided as the `url` property, this property might seem
+  superfluos. However, remember that the `url` property can be `null` if the
+  source map came from a data uri. If so, the sources are relative to the file
+  containing the data uri—`codeUrl`. This property will be identical to the
+  `url` property or `codeUrl`, whichever is appropriate. This way you can
+  conveniently resolve the sources without having to think about where the
+  source map came from.
+- `sourceMappingURL`: The url of the sourceMappingURL comment in `code`.
+
+If `code` contains no sourceMappingURL, the result is `null`.
+
+### `sourceMapResolve.resolveSources(map, mapUrl, read, [options], callback)` ###
+
+- `map` is a source map, as an object (not a string).
+- `mapUrl` is the url to the file containing `map`. Relative sources in the
+  source map, if any, are resolved against `mapUrl`.
+- `read(url, callback)` is a function that reads `url` and responds using
+  `callback(error, content)`. In Node.js you might want to use `fs.readFile`,
+  while in the browser you might want to use an asynchronus `XMLHttpRequest`.
+- `options` is an optional object with any of the following properties:
+  - `sourceRoot`: Override the `sourceRoot` property of the source map, which
+    might only be relevant when resolving sources in the browser. This lets you
+    bypass it when using the module outside of a browser, if needed. Pass a
+    string to replace the `sourceRoot` property with, or `false` to ignore it.
+    Defaults to `undefined`.
+- `callback(error, result)` is a function that is invoked with either an error
+  or `null` and the result.
+
+The result is an object with the following properties:
+
+- `sourcesResolved`: The same as `map.sources`, except all the sources are
+  fully resolved.
+- `sourcesContent`: An array with the contents of all sources in `map.sources`,
+  in the same order as `map.sources`. If getting the contents of a source fails,
+  an error object is put into the array instead.
+
+### `sourceMapResolve.resolve(code, codeUrl, read, [options], callback)` ###
+
+The arguments are identical to `sourceMapResolve.resolveSourceMap`, except that
+you may also provide the same `options` as in `sourceMapResolve.resolveSources`.
+
+This is a convenience method that first resolves the source map and then its
+sources. You could also do this by first calling
+`sourceMapResolve.resolveSourceMap` and then `sourceMapResolve.resolveSources`.
+
+The result is identical to `sourceMapResolve.resolveSourceMap`, with the
+properties from `sourceMapResolve.resolveSources` merged into it.
+
+There is one extra feature available, though. If `code` is `null`, `codeUrl` is
+treated as a url to the source map instead of to `code`, and will be read. This
+is handy if you _sometimes_ get the source map url from the `SourceMap: <url>`
+header (see the [Notes] section). In this case, the `sourceMappingURL` property
+of the result is `null`.
+
+
+[Notes]: #notes
+
+### `sourceMapResolve.*Sync()` ###
+
+There are also sync versions of the three previous functions. They are identical
+to the async versions, except:
+
+- They expect a sync reading function. In Node.js you might want to use
+  `fs.readFileSync`, while in the browser you might want to use a synchronus
+  `XMLHttpRequest`.
+- They throw errors and return the result instead of using a callback.
+
+`sourceMapResolve.resolveSourcesSync` also accepts `null` as the `read`
+parameter. The result is the same as when passing a function as the `read
+parameter`, except that the `sourcesContent` property of the result will be an
+empty array. In other words, the sources aren’t read. You only get the
+`sourcesResolved` property. (This only supported in the synchronus version, since
+there is no point doing it asynchronusly.)
+
+### `sourceMapResolve.parseMapToJSON(string, [data])` ###
+
+The spec says that if a source map (as a string) starts with `)]}'`, it should
+be stripped off. This is to prevent XSSI attacks. This function does that and
+returns the result of `JSON.parse`ing what’s left.
+
+If this function throws `error`, `error.sourceMapData === data`.
+
+### Errors
+
+All errors passed to callbacks or thrown by this module have a `sourceMapData`
+property that contain as much as possible of the intended result of the function
+up until the error occurred.
+
+Note that while the `map` property of result objects always is an object,
+`error.sourceMapData.map` will be a string if parsing that string fails.
+
+
+Note
+====
+
+This module resolves the source map for a given generated file by looking for a
+sourceMappingURL comment. The spec defines yet a way to provide the URL to the
+source map: By sending the `SourceMap: <url>` header along with the generated
+file. Since this module doesn’t retrive the generated code for you (instead
+_you_ give the generated code to the module), it’s up to you to look for such a
+header when you retrieve the file (should the need arise).
+
+
+Development
+===========
+
+Tests
+-----
+
+First off, run `npm install` to install testing modules and browser polyfills.
+
+`npm test` lints the code and runs the test suite in Node.js.
+
+x-package.json5
+---------------
+
+package.json, component.json and bower.json are all generated from
+x-package.json5 by using [`xpkg`]. Only edit x-package.json5, and remember to
+run `xpkg` before commiting!
+
+[`xpkg`]: https://github.com/kof/node-xpkg
+
+Generating the browser version
+------------------------------
+
+source-map-resolve.js is generated from source-map-resolve-node.js and
+source-map-resolve-template.js. Only edit the two latter files, _not_
+source-map-resolve.js! To generate it, run `npm run build`.
