* Fixed a crash when removing an `MGLOfflinePack`. ([#11821](https://github.com/mapbox/mapbox-gl-native/issues/11821))
## 4.0.0 - April 19, 2018
The 4.0._x_ series of releases will be the last to support iOS 8. The minimum iOS deployment version will increase to iOS 9.0 in a future release.
### Packaging
* Removed support for 32-bit simulators. ([#10962](https://github.com/mapbox/mapbox-gl-native/pull/10962))
* Added Danish, Hebrew, and European Portuguese localizations. ([#10967](https://github.com/mapbox/mapbox-gl-native/pull/10967), [#11136](https://github.com/mapbox/mapbox-gl-native/pull/11134), [#11695](https://github.com/mapbox/mapbox-gl-native/pull/11695))
* Removed methods, properties, and constants that had been deprecated as of v3.7.6. ([#11205](https://github.com/mapbox/mapbox-gl-native/pull/11205), [#11681](https://github.com/mapbox/mapbox-gl-native/pull/11681))
* Refined certain Swift interfaces by converting them from class methods to class properties. ([#11674](https://github.com/mapbox/mapbox-gl-native/pull/11674))
* Revamped the “Adding Points to a Map” guide. ([#11496](https://github.com/mapbox/mapbox-gl-native/pull/11496))
### Style layers
* The layout and paint properties on subclasses of `MGLStyleLayer` are now of type `NSExpression` instead of `MGLStyleValue`. A new “Predicates and Expressions” guide provides an overview of the supported operators, which include arithmetic and conditional operators. ([#10726](https://github.com/mapbox/mapbox-gl-native/pull/10726))
* A style can now display a heatmap layer that visualizes a point data distribution. You can customize the appearance at runtime using the `MGLHeatmapStyleLayer` class. ([#11046](https://github.com/mapbox/mapbox-gl-native/pull/11046))
* A style can now display a smooth hillshading layer and customize its appearance at runtime using the `MGLHillshadeStyleLayer` class. Hillshading is based on a rasterized digital elevation model supplied by the `MGLRasterDEMSource` class. ([#10642](https://github.com/mapbox/mapbox-gl-native/pull/10642))
* You can now set the `MGLVectorStyleLayer.predicate` property to a predicate that contains arithmetic and calls to built-in `NSExpression` functions. You may need to cast a feature attribute key to `NSString` or `NSNumber` before comparing it to a string or number. ([#11587](https://github.com/mapbox/mapbox-gl-native/pull/11587))
* Replaced the `MGLStyle.localizesLabels` property with an `-[MGLStyle localizeLabelsIntoLocale:]` method that allows you to specify the language to localize into. Also added an `-[NSExpression(MGLAdditions) mgl_expressionLocalizedIntoLocale:]` method for localizing an individual value used with `MGLSymbolStyleLayer.text`. ([#11651](https://github.com/mapbox/mapbox-gl-native/pull/11651))
* The `MGLSymbolStyleLayer.textFontNames` property can now depend on a feature’s attributes. ([#10850](https://github.com/mapbox/mapbox-gl-native/pull/10850))
* Changes to the `MGLStyleLayer.minimumZoomLevel` and `MGLStyleLayer.maximumZoomLevel` properties take effect immediately. ([#11399](https://github.com/mapbox/mapbox-gl-native/pull/11399))
### Content sources
* Renamed `MGLRasterSource` to `MGLRasterTileSource` and `MGLVectorSource` to `MGLVectorTileSource`. ([#11568](https://github.com/mapbox/mapbox-gl-native/pull/11568))
* Added an `MGLComputedShapeSource` class that allows applications to supply vector data to a style layer on a per-tile basis. ([#9983](https://github.com/mapbox/mapbox-gl-native/pull/9983))
* Properties such as `MGLSymbolStyleLayer.iconAllowsOverlap` and `MGLSymbolStyleLayer.iconIgnoresPlacement` now account for symbols in other sources. ([#10436](https://github.com/mapbox/mapbox-gl-native/pull/10436))
### Map rendering
* Improved the reliability of collision detection between symbols near the edges of tiles, as well as between symbols when the map is tilted. It is no longer necessary to enable `MGLSymbolStyleLayer.symbolAvoidsEdges` to prevent symbols in adjacent tiles from overlapping with each other. ([#10436](https://github.com/mapbox/mapbox-gl-native/pull/10436))
* Symbols can fade in and out as the map pans, rotates, or tilts. ([#10436](https://github.com/mapbox/mapbox-gl-native/pull/10436))
* Fixed an issue preventing a dynamically-added `MGLRasterStyleLayer` from drawing until the map pans. ([#10270](https://github.com/mapbox/mapbox-gl-native/pull/10270))
* Fixed an issue preventing `MGLImageSource`s from drawing on the map when the map is zoomed in and tilted. ([#10677](https://github.com/mapbox/mapbox-gl-native/pull/10677))
* Improved the sharpness of raster tiles on Retina displays. ([#10984](https://github.com/mapbox/mapbox-gl-native/pull/10984))
* Fixed a crash parsing a malformed style. ([#11001](https://github.com/mapbox/mapbox-gl-native/pull/11001))
* Reduced memory usage by clearing in-memory tile cache before entering background. ([#11197](https://github.com/mapbox/mapbox-gl-native/pull/11197))
* Fixed an issue where symbols with empty labels would always be hidden. ([#11206](https://github.com/mapbox/mapbox-gl-native/pull/11206))
* Fixed an issue where a tilted map could flicker while displaying rotating symbols. ([#11488](https://github.com/mapbox/mapbox-gl-native/pull/11488))
* Increased the maximum width of labels by a factor of two. ([#11508](https://github.com/mapbox/mapbox-gl-native/pull/11508))
### Annotations
* Changed the default value of `MGLAnnotationView.scalesWithViewingDistance` to `NO`, to improve performance. If your use case involves many annotation views, consider keeping this property disabled. ([#11636](https://github.com/mapbox/mapbox-gl-native/pull/11636))
* Fixed an issue preventing `MGLAnnotationImage.image` from being updated. ([#10372](https://github.com/mapbox/mapbox-gl-native/pull/10372))
* Improved performance of `MGLAnnotationView`-backed annotations that have `scalesWithViewingDistance` enabled. ([#10951](https://github.com/mapbox/mapbox-gl-native/pull/10951))
* Fixed an issue where tapping a group of annotations may not have selected the nearest annotation. ([#11438](https://github.com/mapbox/mapbox-gl-native/pull/11438))
* The `MGLMapView.selectedAnnotations` property (backed by `-[MGLMapView setSelectedAnnotations:]`) now selects annotations that are off-screen. ([#9790](https://github.com/mapbox/mapbox-gl-native/issues/9790))
* The `animated` parameter to `-[MGLMapView selectAnnotation:animated:]` now controls whether the annotation and its callout are brought on-screen. If `animated` is `NO` then the annotation is selected if offscreen, but the map is not panned. Currently only point annotations are supported. Setting the `MGLMapView.selectedAnnotations` property now animates. ([#3249](https://github.com/mapbox/mapbox-gl-native/issues/3249))
* Fixed a crash when rapidly adding and removing annotations. ([#11551](https://github.com/mapbox/mapbox-gl-native/issues/11551), [#11575](https://github.com/mapbox/mapbox-gl-native/issues/11575))
* Marked protocol method `-[MGLCalloutView presentCalloutFromRect:inView:constrainedToView:animated:]` as unavailable. Use `-[MGLCalloutView presentCalloutFromRect:inView:constrainedToRect:animated:]` instead. ([#11738](https://github.com/mapbox/mapbox-gl-native/pull/11738))
### Map snapshots
* Fixed a memory leak that occurred when creating a map snapshot. ([#10585](https://github.com/mapbox/mapbox-gl-native/pull/10585))
### Other changes
* The `-[MGLMapView convertRect:toCoordinateBoundsFromView:]` method and the `MGLMapView.visibleCoordinateBounds` property’s getter now indicate that the coordinate bounds straddles the antimeridian by extending one side beyond ±180 degrees longitude. ([#11265](https://github.com/mapbox/mapbox-gl-native/pull/11265))
* Feature querying results now account for the `MGLSymbolStyleLayer.circleStrokeWidth` property. ([#10897](https://github.com/mapbox/mapbox-gl-native/pull/10897))
* Fixed an issue preventing labels from being transliterated when VoiceOver was enabled on iOS 10._x_ and below. ([#10881](https://github.com/mapbox/mapbox-gl-native/pull/10881))
* Labels are now transliterated from more languages when VoiceOver is enabled. ([#10881](https://github.com/mapbox/mapbox-gl-native/pull/10881))
* Long-pressing the attribution button causes the SDK’s version number to be displayed in the action sheet that appears. ([#10650](https://github.com/mapbox/mapbox-gl-native/pull/10650))
* Reduced offline download sizes for styles with symbol layers that render only icons, and no text. ([#11055](https://github.com/mapbox/mapbox-gl-native/pull/11055))
* Added haptic feedback that occurs when the user rotates the map to due north, configurable via `MGLMapView.hapticFeedbackEnabled`. ([#10847](https://github.com/mapbox/mapbox-gl-native/pull/10847))
* Added `MGLMapView.showsScale` as the recommended way to show the scale bar. This property can be set directly in Interface Builder. ([#11335](https://github.com/mapbox/mapbox-gl-native/pull/11335))
* Fixed an issue where the scale bar would not appear until the map had moved. ([#11335](https://github.com/mapbox/mapbox-gl-native/pull/11335))
