## 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).

## 0.54.0

### Breaking changes

- 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). Add `localIdeographFontFamily: false` to turn this off. [#8008](https://github.com/mapbox/mapbox-gl-js/pull/8008)
- Added `Popup` `maxWidth` option, set to `"240px"` by default. [#7906](https://github.com/mapbox/mapbox-gl-js/pull/7906)

### Major features

- Added support for updating and animating style images. [#7999](https://github.com/mapbox/mapbox-gl-js/pull/7999)

- Added `rel="noopener"` attributes to links that lead to external websites (such as Mapbox logo and OpenStreetMap edit link) for improved security. [#7914](https://github.com/mapbox/mapbox-gl-js/pull/7914)
- Added tile size info when `map.showTileBoundaries` is turned on. [#7963](https://github.com/mapbox/mapbox-gl-js/pull/7963)
- Significantly improved load times of the benchmark suite. [#8066](https://github.com/mapbox/mapbox-gl-js/pull/8066)

* Always hide duplicate labels [#6166](https://github.com/mapbox/mapbox-gl-js/pull/6166)
* Fix `DragHandler` bugs where a left-button mouse click would end a right-button drag rotate and a drag gesture would not end if the control key is down on `mouseup` [#6193](https://github.com/mapbox/mapbox-gl-js/pull/6193)
