- Revert default behavior of symbol occlusion behind terrain to maintain compatibility. Set `icon-occlusion-opacity`/`text-occlusion-opacity` properties to opt-in to new occlusion behavior.

## 3.5.0

### Breaking changes ⚠️
- This release marks a significant transition for GL JS, moving from [Flow](https://flow.org/) to [TypeScript](https://www.typescriptlang.org/). While we have maintained backward compatibility where possible, the community typings `@types/mapbox-gl` are not fully compatible with the new first-class typings. Users relying on the community typings may experience breaking changes. Please remove the `@types/mapbox-gl` dependency and refer to the [v3.5.0 migration guide](https://github.com/mapbox/mapbox-gl-js/issues/13203) for instructions on upgrading, resolving common issues, and asking questions regarding the migration to the first-class typings. We welcome your feedback and contributions to make Mapbox GL JS better.

## 2.6.0

### ✨ Features and improvements

* Add support for a variety of new map projections beyond the standard Web Mercator. Alternate projections can be used together with all existing styles and sources. The projections eliminate distortion as you zoom to make them useful at every scale. Supported projections include `albers`, `equalEarth`, `equirectangular`, `lambertConformalConic`, `naturalEarth` and `winkelTripel`. Change the projection by setting it in the map constructor: `new Map({ projection: 'winkelTripel', ... })`. ([#11124](https://github.com/mapbox/mapbox-gl-js/pull/11124))
    * Limitations: Non-mercator projections do not yet support terrain, fog, free camera or CustomLayerInterface.

* Improve user accessibility: conveying only `aria-label` in controls, replace `aria-pressed`with `aria-expanded` in the attribution control, interactive markers with popups express an `aria-expanded` state, and interactive markers have the role "button". ([#11064](https://github.com/mapbox/mapbox-gl-js/pull/11064))
* Add support for conditionally styling most paint properties according to the presence or absence of specific images. ([#11049](https://github.com/mapbox/mapbox-gl-js/pull/11049))
* Add support for attaching events to multiple layers with `map.on()`, allowing users to retrieve features under the mouse or touch event based on the order in which they are rendered.  ([#11114](https://github.com/mapbox/mapbox-gl-js/pull/11114))(h/t [@omerbn](https://github.com/omerbn))

By upgrading to this release, you are agreeing to [Mapbox terms of service](https://www.mapbox.com/legal/tos/).** Refer to LICENSE.txt for the new licensing terms and details. For questions, contact our team at [https://support.mapbox.com](https://support.mapbox.com).
- Beginning with v2.0.0, a billable map load occurs whenever a Map object is initialized. Before updating an existing implementation from v1.x.x to v2.x.x, please review the [pricing documentation](https://docs.mapbox.com/accounts/guides/pricing/#mapbox-gl-js-v100-and-higher) to estimate expected costs.
- Deprecate Internet Explorer 11, no longer supported from this release. ([#8283](https://github.com/mapbox/mapbox-gl-js/issues/8283), [#6391](https://github.com/mapbox/mapbox-gl-js/issues/6391))
- Support for unlocked pitch up to 85°. The  default `maxPitch` is increased from 60° to 85° which can result in viewing above the horizon line. By default, this area will be drawn transparent but a new sky layer can be added to the map in order to fill this space. The legacy behavior can be achieved by simply adding `maxPitch: 60` to the map options when instantiating your map.

### ✨ Features and improvements

- Add 3D terrain feature. All layer types and markers can now be extruded using the new `terrain` root level style-spec property or with the function `map.setTerrain()`. ([#1489](https://github.com/mapbox/mapbox-gl-js/issues/1489))
- Add support for unlocked pitch up to 85° (previously 60°). ([#3731](https://github.com/mapbox/mapbox-gl-js/issues/3731))
- Add a new sky layer acting as an infinite background above the horizon line. This layer can be used from the style-spec and has two types: `atmospheric` and `gradient`.
- Add a free form camera API, allowing for more complex camera manipulation in 3D, accessible using `map.getFreeCameraOptions()` and `map.setFreeCameraOptions()`.
- Improve performance by adopting a two-phase tile loading strategy, prioritizing rendering of non-symbol layers first.
- Improve performance by avoiding parsing vector tiles that were already aborted.
- Improve performance by adopting a preemptive shader compilation strategy. ([#9384](https://github.com/mapbox/mapbox-gl-js/issues/9384))
- Improve performance by disabling fade-in animation for symbols and raster tiles on initial map load.
- Improve performance by defaulting to 2 workers on all platforms. ([#3153](https://github.com/mapbox/mapbox-gl-js/issues/3153))
- Improve performance by loading tiles on the main thread at initial map load.
- Improve performance by using better worker task scheduling.

### 🐞 Bug fixes

- Avoid reloading `raster` and `raster-dem` tiles when the RTLTextPlugin loads.
- Add runtime evaluation of label collision boxes for more accurate symbol placement at fractional zoom levels and tilted views.
- Fix tile cache size for terrain DEM sources.
- Prevent holding on to DEM memory on the worker.
- Reduce memory used by `fill-extrusion`s.

### 🛠️ Workflow

- Run render tests in browser.

### 🍏 Gestures
This release significantly refactors and improves gesture handling on desktop and mobile. Three new touch gestures have been added: `two-finger swipe` to adjust pitch, `two-finger double tap` to zoom out, and `tap then drag` to adjust zoom with one finger ([#9365](https://github.com/mapbox/mapbox-gl-js/pull/9365)). In addition, this release brings the following changes and bug fixes:

- It's now possible to interact with multiple maps on the same page at the same time ([#9365](https://github.com/mapbox/mapbox-gl-js/pull/9365))
- Fix map jump when releasing one finger after pinch zoom ([#9136](https://github.com/mapbox/mapbox-gl-js/issues/9136))

- Stop mouse wheel from interrupting animations when `map.scrollZoom` is disabled ([#9230](https://github.com/mapbox/mapbox-gl-js/issues/9230))
- A camera change can no longer be prevented by disabling the interaction handler within the camera change event. Selectively prevent camera changes by listening to the `mousedown` or `touchstart` map event and calling [.preventDefault()](https://docs.mapbox.com/mapbox-gl-js/api/#mapmouseevent#preventdefault) ([#9365](https://github.com/mapbox/mapbox-gl-js/pull/9365))
- Undocumented properties on the camera change events fired by the doubleClickZoom handler have been removed ([#9365](https://github.com/mapbox/mapbox-gl-js/pull/9365))

## 1.9.0
With this release, we're adding [a new changelog policy](./CONTRIBUTING.md#changelog-conventions) to our contribution guidelines.

This release also fixes several long-standing bugs and unintentional rendering behavior with `line-pattern`. The fixes come with a visual change to how patterns added with `line-pattern` scale. Previously, patterns that became larger than the line would be clipped, sometimes distorting the pattern, particularly on mobile and retina devices. Now the pattern will be scaled to fit under all circumstances. [#9266](https://github.com/mapbox/mapbox-gl-js/pull/9266) showcases examples of the visual differences. For more information and to provide feedback on this change, see [#9394](https://github.com/mapbox/mapbox-gl-js/pull/9394).

### ✨ Features
* Add `within` expression for testing whether an evaluated feature lies within a given GeoJSON object ([#9352](https://github.com/mapbox/mapbox-gl-js/pull/9352)).
    - We are aware of an edge case in which points with wrapped coordinates (e.g. longitude -185) are not evaluated properly. See ([#9442](https://github.com/mapbox/mapbox-gl-js/issues/9442)) for more information.
    - An example of the `within` expression:<br>
`"icon-opacity": ["case", ["==", ["within", "some-polygon"], true], 1,
["==", ["within", "some-polygon"], false], 0]`
* Map API functions such as `easeTo` and `flyTo` now support `padding: PaddingOptions` which lets developers shift a map's center of perspective when building floating sidebars ([#8638](https://github.com/mapbox/mapbox-gl-js/pull/8638))

### 🍏 Improvements
* Results from `queryRenderedFeatures` now have evaluated property values rather than raw expressions ([#9198](https://github.com/mapbox/mapbox-gl-js/pull/9198))
* Improve scaling of patterns used in `line-pattern` on all device resolutions and pixel ratios ([#9266](https://github.com/mapbox/mapbox-gl-js/pull/9266))
* Slightly improve GPU memory footprint ([#9377](https://github.com/mapbox/mapbox-gl-js/pull/9377))
* `LngLatBounds.extend` is more flexible because it now accepts objects with `lat` and `lon` properties as well as arrays of coordinates ([#9293](https://github.com/mapbox/mapbox-gl-js/pull/9293))
* Reduce bundle size and improve visual quality of `showTileBoundaries` debug text ([#9267](https://github.com/mapbox/mapbox-gl-js/pull/9267))

### 🐞 Bug fixes
* Correctly adjust patterns added with `addImage(id, image, pixelRatio)` by the asset pixel ratio, not the device pixel ratio ([#9372](https://github.com/mapbox/mapbox-gl-js/pull/9372))
* Allow needle argument to `in` expression to be false ([#9295](https://github.com/mapbox/mapbox-gl-js/pull/9295))
* Fix exception thrown when trying to set `feature-state` for a layer that has been removed, fixes [#8634](https://github.com/mapbox/mapbox-gl-js/issues/8634) ([#9305](https://github.com/mapbox/mapbox-gl-js/pull/9305))
* Fix a bug where maps were not displaying inside elements with `dir=rtl` ([#9332](https://github.com/mapbox/mapbox-gl-js/pull/9332))
* Fix a rendering error for very old versions of Chrome (ca. 2016) where text would appear much bigger than intended ([#9349](https://github.com/mapbox/mapbox-gl-js/pull/9349))
* Prevent exception resulting from `line-dash-array` of empty length ([#9385](https://github.com/mapbox/mapbox-gl-js/pull/9385))
* Fix a bug where `icon-image` expression that evaluates to an empty string (`''`) produced a warning ([#9380](https://github.com/mapbox/mapbox-gl-js/pull/9380))
* Fix a bug where certain `popup` methods threw errors when accessing the container element before it was created, fixes [#9429](https://github.com/mapbox/mapbox-gl-js/issues/9429)([#9433](https://github.com/mapbox/mapbox-gl-js/pull/9433))

## 1.5.1
This patch introduces two workarounds that address longstanding issues related to unbounded memory growth in Safari, including [#8771](https://github.com/mapbox/mapbox-gl-js/issues/8771) and [#4695](https://github.com/mapbox/mapbox-gl-js/issues/4695). We’ve identified two memory leaks in Safari: one in the [CacheStorage](https://developer.mozilla.org/en-US/docs/Web/API/CacheStorage) API, addressed by [#8956](https://github.com/mapbox/mapbox-gl-js/pull/8956), and one in transferring data between web workers through [Transferables](https://developer.mozilla.org/en-US/docs/Web/API/Transferable), addressed by [#9003](https://github.com/mapbox/mapbox-gl-js/pull/9003).

## 1.0.0

### ⚠️ Breaking changes

This release replaces the existing “map views” pricing model in favor of a “map load” model. Learn more in [a recent blog post about these changes](https://blog.mapbox.com/new-pricing-46b7c26166e7).

**By upgrading to this release, you are opting in to the new map loads pricing.**

**Why is this change being made?**

This change allows us to implement a more standardized and predictable method of billing GL JS map usage. You’ll be charged whenever your website or web application loads, not by when users pan and zoom around the map, incentivizing developers to create highly interactive map experiences. The new pricing structure also creates a significantly larger free tier to help developers get started building their applications with Mapbox tools while pay-as-you-go pricing and automatic volume discounts help your application scale with Mapbox. Session billing also aligns invoices with metrics web developers already track and makes it easier to compare usage with other mapping providers.

**What is changing?**
- Add SKU token to Mapbox API requests [#8276](https://github.com/mapbox/mapbox-gl-js/pull/8276)

When (and only when) loading tiles from a Mapbox API with a Mapbox access token set (`mapboxgl.accessToken`), a query parameter named `sku` will be added to all requests for vector, raster and raster-dem tiles. Every map instance uses a unique `sku` value, which is refreshed every 12 hours. The token itself is comprised of a token version (always “1”), a sku ID (always “01”) and a random 10-digit base-62 number. The purpose of the token is to allow for metering of map sessions on the server-side. A session lasts from a new map instantiation until the map is destroyed or 12 hours passes, whichever comes first.

For further information on the pricing changes, you can read our [blog post](https://blog.mapbox.com/new-pricing-46b7c26166e7) and check out our new [pricing page](https://www.mapbox.com/pricing), which has a price calculator. As always, you can also contact our team at [https://support.mapbox.com](https://support.mapbox.com).

- Turned `localIdeographFontFamily` map option on by default. This may change how CJK labels are rendered, but dramatically improves performance of CJK maps (because the browser no longer needs to download heavy amounts of font data from the server).

- A [heatmap](https://www.mapbox.com/mapbox-gl-js/example/heatmap-layer/) layer type is now available. This layer type allows you to visualize and explore massive datasets of points, reflecting the shape and density of data well while also looking beautiful. See [the blog post](https://blog.mapbox.com/sneak-peek-at-heatmaps-in-mapbox-gl-73b41d4b16ae) for further details.
  ![](https://cdn-images-1.medium.com/max/1600/1*Dme5MAgdA3pYdTRHUQzvLw.png)
- The value of a style property or filter can now be an [expression](http://www.mapbox.com/mapbox-gl-js/style-spec/#expressions). Expressions are a way of doing data-driven and zoom-driven styling that provides more flexibility and control, and unifies property and filter syntax.

  Previously, data-driven and zoom-driven styling relied on stop functions: you specify a feature property and a set of input-output pairs that essentially define a “scale” for how the style should be calculated based on the feature property. For example, the following would set circle colors on a green-to-red scale based on the value of `feature.properties.population`:

  ```
  "circle-color": {
    "property": "population",
    "stops": [
      [0, "green"],
      [1000000, "red"]
    ]
  }
  ```

  This approach is powerful, but we’ve seen a number of use cases that stop functions don't satisfy. Expressions provide the flexibility to address use cases like these:

  **Multiple feature properties**
  Using more than one feature property to calculate a given style property. E.g., styling land polygon colors based on both `feature.properties.land_use_category` and `feature.properties.elevation`.

  **Arithmetic**
  For some use cases it’s necessary to do some arithmetic on the input data. One example is sizing circles to represent quantitative data. Since a circle’s visual size on the screen is really its area (and A=πr^2), the right way to scale `circle-radius` is `square_root(feature.properties.input_data_value)`. Another example is unit conversions: feature data may include properties that are in some particular unit. Displaying such data in units appropriate to, say, a user’s preference or location, requires being able to do simple arithmetic (multiplication, division) on whatever value is in the data.

  **Conditional logic**
  This is a big one: basic if-then logic, for example to decide exactly what text to display for a label based on which properties are available in the feature or even the length of the name. A key example of this is properly supporting bilingual labels, where we have to decide whether to show local + English, local-only, or English-only, based on the data that’s available for each feature.

  **String manipulation**
  More dynamic control over label text with things like uppercase/lowercase/title case transforms, localized number formatting, etc. Without this functionality, crafting and iterating on label content entails a large data-prep burden.

  **Filters**
  Style layer filters had similar limitations. Moreover, they use a different syntax, even though their job is very similar to that of data-driven styling functions: filters say, “here’s how to look at a feature and decide whether to draw it,” and data-driven style functions say, “here’s how to look at a feature and decide how to size/color/place it.” Expressions provide a unified syntax for defining parts of a style that need to be calculated dynamically from feature data.

  For information on the syntax and behavior of expressions, please see [the documentation](http://www.mapbox.com/mapbox-gl-js/style-spec/#expressions).

- `GeolocateControl` breaking changes #4479
  * The option `watchPosition` has been replaced with `trackUserLocation`
  * The camera operation has changed from `jumpTo` (not animated) to `fitBounds` (animated). An effect of this is the map pitch is no longer reset, although the bearing is still reset to 0.
  * The accuracy of the geolocation provided by the device is used to set the view (previously it was fixed at zoom level 17). The `maxZoom` can be controlled via the new `fitBoundsOptions` option (defaults to 15).

    * Rename `layer` parameter to `layers` and make it an array of layer names.
    * Remove the `radius` parameter. `radius` was used with `featuresAt` to account for style properties like `line-width` and `circle-radius`. `queryRenderedFeatures` accounts for these style properties. If you need to query a larger area, use a bounding box query instead of a point query.
    * Remove the `includeGeometry` parameter because `queryRenderedFeatures` always includes geometries.

## 0.10.0 (Aug 21 2015)

#### Breaking changes

* Switched to [longitude, latitude] coordinate order, matching GeoJSON. We anticipate that mapbox-gl-js will be widely used
  with GeoJSON, and in the long term having a coordinate order that is consistent with GeoJSON will lead to less confusion
  and impedance mismatch than will a [latitude, longitude] order.

  The following APIs were renamed:

    * `LatLng` was renamed to `LngLat`
    * `LatLngBounds` was renamed to `LngLatBounds`
    * `Popup#setLatLng` was renamed to `Popup#setLngLat`
    * `Popup#getLatLng` was renamed to `Popup#getLngLat`
    * The `latLng` property of Map events was renamed `lngLat`

  The following APIs now expect array coordinates in [longitude, latitude] order:

    * `LngLat.convert`
    * `LngLatBounds.convert`
    * `Popup#setLngLat`
    * The `center` and `maxBounds` options of the `Map` constructor
    * The arguments to `Map#setCenter`, `Map#fitBounds`, `Map#panTo`, and `Map#project`
    * The `center` option of `Map#jumpTo`, `Map#easeTo`, and `Map#flyTo`
    * The `around` option of `Map#zoomTo`, `Map#rotateTo`, and `Map#easeTo`
    * The `coordinates` properties of video and image sources

* Updated to mapbox-gl-style-spec v8.0.0 ([Changelog](https://github.com/mapbox/mapbox-gl-style-spec/blob/v8.0.0/CHANGELOG.md)). Styles are
  now expected to be version 8. You can use the [gl-style-migrate](https://github.com/mapbox/mapbox-gl-style-lint#migrations)
  utility to update existing styles.

* The format for `mapbox://` style and glyphs URLs has changed. For style URLs, you should now use the format
  `mapbox://styles/:username/:style`. The `:style` portion of the URL no longer contains a username. For font URLs, you
  should now use the format `mapbox://fonts/:username/{fontstack}/{range}.pbf`.
* Mapbox default styles are now hosted via the Styles API rather than www.mapbox.com. You can make use of the Styles API
  with a `mapbox://` style URL pointing to a v8 style, e.g. `mapbox://styles/mapbox/streets-v8`.
* The v8 satellite style (`mapbox://styles/mapbox/satellite-v8`) is now a plain satellite style, and not longer supports labels
  or contour lines via classes. For a labeled satellite style, use `mapbox://styles/mapbox/satellite-hybrid`.

* Removed `mbgl.config.HTTP_URL` and `mbgl.config.FORCE_HTTPS`; https is always used when connecting to the Mapbox API.
* Renamed `mbgl.config.HTTPS_URL` to `mbgl.config.API_URL`.

#### Bugfixes

* Don't draw halo when halo-width is 0 (#1381)
* Reverted shader changes that degraded performance on IE

#### API Improvements

* You can now unset layout and paint properties via the `setLayoutProperty` and `setPaintProperty` APIs
  by passing `undefined` as a property value.
* The `layer` option of `featuresAt` now supports an array of layers.

## 0.9.0 (Jul 29 2015)

* `glyphs` URL now normalizes without the `/v4/` prefix for `mapbox://` urls. Legacy behavior for `mapbox://fontstacks` is still maintained (#1385)
* Expose `geojson-vt` options for GeoJSON sources (#1271)
* bearing snaps to "North" within a tolerance of 7 degrees (#1059)
* Now you can directly mutate the minzoom and maxzoom layer properties with `map.setLayerZoomRange(layerId, minzoom, maxzoom)`
* Exposed `mapboxgl.Control`, a base class used by all UI controls
* Refactored handlers to be individually included in Map options, or enable/disable them individually at runtime, e.g. `map.scrollZoom.disable()`.
* New feature: Batch operations can now be done at once, improving performance for calling multiple style functions: (#1352)

  ```js
  style.batch(function(s) {
      s.addLayer({ id: 'first', type: 'symbol', source: 'streets' });
      s.addLayer({ id: 'second', type: 'symbol', source: 'streets' });
      s.addLayer({ id: 'third', type: 'symbol', source: 'terrain' });
      s.setPaintProperty('first', 'text-color', 'black');
      s.setPaintProperty('first', 'text-halo-color', 'white');
  });
  ```

## 0.8.1 (Jun 16 2015)

* No code changes; released only to correct a build issue in 0.8.0.

## 0.8.0 (Jun 15 2015)

#### Breaking changes

* `map.setView(latlng, zoom, bearing)` has been removed. Use
  [`map.jumpTo(options)`](https://www.mapbox.com/mapbox-gl-js/api/#map/jumpto) instead:

  ```js
  map.setView([40, -74.50], 9) // 0.7.0 or earlier
  map.jumpTo({center: [40, -74.50], zoom: 9}); // now
  ```
* [`map.easeTo`](https://www.mapbox.com/mapbox-gl-js/api/#map/easeto) and
  [`map.flyTo`](https://www.mapbox.com/mapbox-gl-js/api/#map/flyto) now accept a single
  options object rather than positional parameters:

  ```js
  map.easeTo([40, -74.50], 9, null, {duration: 400}); // 0.7.0 or earlier
  map.easeTo({center: [40, -74.50], zoom: 9, duration: 400}); // now
  ```
* `mapboxgl.Source` is no longer exported. Use `map.addSource()` instead. See the
  [GeoJSON line](https://www.mapbox.com/mapbox-gl-js/example/geojson-line/) or
  [GeoJSON markers](https://www.mapbox.com/mapbox-gl-js/example/geojson-markers/)
  examples.

## 0.3.0 (Sep 23 2014)

#### Breaking

- Updated to mapbox-gl-style-spec v0.0.5 ([Changelog](https://github.com/mapbox/mapbox-gl-style-spec/blob/v0.0.5/CHANGELOG.md)). Styles are
  now expected to be version 5. You can use the [gl-style-migrate](https://github.com/mapbox/mapbox-gl-style-lint#migrations)
  utility to update existing styles.
- Removed support for composite layers for performance reasons. [#523](https://github.com/mapbox/mapbox-gl-js/issues/523#issuecomment-51731405)
- `raster-hue-rotate` units are now degrees.

### Improvements

- Added LatLng#wrap
- Added support for Mapbox fontstack API.
- Added support for remote, non-Mapbox TileJSON sources and inline TileJSON sources (#535, #698).
- Added support for `symbol-avoid-edges` property to allow labels to be placed across tile edges.
- Fixed mkdir issue on Windows (#674).
- Fixed drawing beveled line joins without overlap.

#### Bugfixes

- Fixed performance when underzooming a layer's minzoom.
- Fixed `raster-opacity` for regular raster layers.
- Fixed various corner cases of easing functions.
- Do not modify original stylesheet (#728).
- Inherit video source from source (#699).
- Fixed interactivity for geojson layers.
- Stop dblclick on navigation so the map does not pan (#715).

## 0.2.2 (Aug 12 2014)

#### Breaking

- `map.setBearing()` no longer supports a second argument. Use `map.rotateTo` with an `offset` option and duration 0
if you need to rotate around a point other than the map center.

#### Improvements

- Improved `GeoJSONSource` to also accept URL as `data` option, eliminating a huge performance bottleneck in case of large GeoJSON files.
[#669](https://github.com/mapbox/mapbox-gl-js/issues/669) [#671](https://github.com/mapbox/mapbox-gl-js/issues/671)
- Switched to a different fill outlines rendering approach. [#668](https://github.com/mapbox/mapbox-gl-js/issues/668)
- Made the minified build 12% smaller gzipped (66 KB now).
- Added `around` option to `Map` `zoomTo`/`rotateTo`.
- Made the permalink hash more compact.
- Bevel linejoins no longer overlap and look much better when drawn with transparency.

#### Bugfixes

- Fixed the **broken minified build**. [#679](https://github.com/mapbox/mapbox-gl-js/issues/679)
- Fixed **blurry icons** rendering. [#666](https://github.com/mapbox/mapbox-gl-js/issues/666)
- Fixed `util.supports` WebGL detection producing false positives in some cases. [#677](https://github.com/mapbox/mapbox-gl-js/issues/677)
- Fixed invalid font configuration completely blocking tile rendering.  [#662](https://github.com/mapbox/mapbox-gl-js/issues/662)
- Fixed `Map` `project`/`unproject` to properly accept array-form values.
- Fixed sprite loading race condition. [#593](https://github.com/mapbox/mapbox-gl-js/issues/593)
- Fixed `GeoJSONSource` `setData` not updating the map until zoomed or panned. [#676](https://github.com/mapbox/mapbox-gl-js/issues/676)

## 0.2.1 (Aug 8 2014)

#### Breaking

- Changed `Navigation` control signature: now it doesn't need `map` in constructor
and gets added with `map.addControl(nav)` or `nav.addTo(map)`.
- Updated CSS classes to have consistent naming prefixed with `mapboxgl-`.

#### Improvements

- Added attribution control (present by default, disable by passing `attributionControl: false` in options).
- Added rotation by dragging the compass control.
- Added grabbing cursors for the map by default.
- Added `util.inherit` and `util.debounce` functions.
- Changed the default debug page style to OSM Bright.
- Token replacements now support dashes.
- Improved navigation control design.

#### Bugfixes

- Fixed compass control to rotate its icon with the map.
- Fixed navigation control cursors.
- Fixed inertia going to the wrong direction in a rotated map.
- Fixed inertia race condition where error was sometimes thrown after erratic panning/zooming.


## 0.2.0 (Aug 6 2014)

- First public release.
