• Use setData operation when diffing geojson sources #5332

• Return early from draw calls on layers where opacity=0 #5429

• A heatmap 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 for further details.

• The value of a style property or filter can now be an expression. 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.

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). Styles are now expected to be version 8. You can use the gl-style-migrate 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

• 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)

  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');
  });

0.8.0 (Jun 15 2015)

Breaking changes

• map.setView(latlng, zoom, bearing) has been removed. Use map.jumpTo(options) instead:

  map.setView([40, -74.50], 9) // 0.7.0 or earlier
  map.jumpTo({center: [40, -74.50], zoom: 9}); // now

• map.easeTo and map.flyTo now accept a single options object rather than positional parameters:

  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 or GeoJSON markers examples.

• mapboxgl.util.supported() moved to mapboxgl.supported().
