* Fix: Make `transferMyPlayback` not require the `options` object, since it should be optional. Thanks for the heads-up [@Simber1](https://github.com/Simber1)!
* This package can currently not be built on **Node 15 on Linux**, due to a dependency not being available yet. Issue can be followed on the [node-canvas](https://github.com/Automattic/node-canvas/issues/1688) issue tracker. In the mean time, Travis CI will run on earlier versions of Node.
* Arguments for some API methods have changed, causing incorrect behaviour using argument order from version 4.x. See the `README.md` for examples of how the methods can be used.
Cheers [@marinacrachi](https://github.com/marinacrachi) for the createPlaylist update.
* Removed legacy support for not passing an `options` object while providing a callback method. This was only supported on a few of the older endpoints, and could lead to tricky bugs. The affected endpoints are `getTrack`, `getTracks`, `getAlbum`, `getAlbums`, and `createPlaylist`. Again, check the `README.md` for examples on how these methods can be used if needed.
* Removed `options` argument for retrieving an access token using the Client Credentials flow, `clientCredentialsGrant`.
* API errors come in five different flavours.
* WebapiRegularError - For errors returned by most API endpoints.
More importantly, errors now contain the response body, headers, and status code. One side-effect of this is that rate limited requests can be handled by checking the `Retry-After` header. Thanks for the PRs [@kauffecup](https://github.com/kauffecup), [@lantelyes](https://github.com/lantelyes), [@dkliemsch](https://github.com/dkliemsch), and [@erezny](https://github.com/erezny).

#### 3.1.1 (29 Apr 2018)
* Modernized stack for a better developer experience. Integrated [prettier](https://github.com/thelinmichael/spotify-web-api-node/pull/205) and [jest](https://github.com/thelinmichael/spotify-web-api-node/pull/206). This simplifies the amount of dev dependencies.
* Improved calls to save and remove saved tracks by adding a key as specified in the Spotify docs (See [PR](https://github.com/thelinmichael/spotify-web-api-node/pull/207)). Thanks to [@yanniz0r](https://github.com/yanniz0r) and [@adcar](https://github.com/adcar) for bringing it up.

* Added support for seeking and setting volume. Thanks to [@isokar](https://github.com/isokar), [@jamesemwallis](https://github.com/jamesemwallis), [@ashthespy](https://github.com/ashthespy), and [@vanderlin](https://github.com/vanderlin) for your PRs.
#### 3.0.0 (8 Mar 2018)
*@DalerAsrorov added support for uploading a custom image to a playlist in [this PR](https://github.com/thelinmichael/spotify-web-api-node/pull/169).
* You can now pass a `device_id` when playing and pausing playback. @pfftdammitchris started [a PR to add device_id to the play() method](https://github.com/thelinmichael/spotify-web-api-node/pull/185). The changes served to another PR where we included the functionality. Thanks!
* Added documentation in the README for `getMyCurrentPlaybackState()`. Thanks @PanMan for [your PR](https://github.com/thelinmichael/spotify-web-api-node/pull/160)!
*@brodin realized we there was a lot of duplicated code and refactored it in a [great PR](https://github.com/thelinmichael/spotify-web-api-node/pull/123).
#### 2.5.0 (4 Sep 2017)
* Change README to reflect new authorization. Thanks [@arirawr](https://github.com/arirawr) for the [PR](https://github.com/thelinmichael/spotify-web-api-node/pull/146).
* Add support for 'show_dialog' parameter when creating authorization url. Thanks [@ajhaupt7](https://github.com/ajhaupt7) for [the PR](https://github.com/thelinmichael/spotify-web-api-node/pull/101).
* Add support for playback control (play, pause, prev, next), shuffle and repeat. Thanks [@JoseMCO](https://github.com/JoseMCO) for [the PR](https://github.com/thelinmichael/spotify-web-api-node/pull/150).

* Change `addTracksToPlaylist` to pass the data in the body, preventing an issue with a long URL when passing many tracks. Thanks [@dolcalmi](https://github.com/dolcalmi) for [the PR](https://github.com/thelinmichael/spotify-web-api-node/pull/117)
* Add support for fetching [recently played tracks](https://developer.spotify.com/web-api/console/get-recently-played/). Thanks [@jeremyboles](https://github.com/jeremyboles) for [the PR](https://github.com/thelinmichael/spotify-web-api-node/pull/111).
* Use `encodeURIComponent` instead of `encodeURI` to encode the user's id. 'encodeURI' wasn't encoding characters like `/` or `#` that were generating an invalid endpoint url. Thanks [@jgranstrom](https://github.com/jgranstrom) for the PR.
#### 2.3.4 (18 July 2016)
* Fixed a bug in `clientCredentialsGrant()`.
#### 2.3.3 (18 July 2016)

Read more about the endpoints in the links above or in this [blog post](https://developer.spotify.com/news-stories/2016/03/29/api-improvements-update/).
* Add generic search method enabling searches for several types at once, e.g. search for both tracks and albums in a single request, instead of one request for track results and one request for album results.
* Add language bindings for **[Get User's Saved Albums](https://developer.spotify.com/web-api/get-users-saved-albums/)** and other endpoints related to the user's saved albums.
