0.4.9-android

This is a major update to the Tangram Android SDK. There are breaking changes to the API in this release, as well as some new interfaces.

Features

• The Tangram Android SDK now uses the CMake external native build process introduced in Android Studio 2.2. This simplifies Android build process and enables building Tangram for Android on Windows (#1152).
• Scene updates can now be applied when a scene is first loaded. This is a faster, more convenient way to apply settings like API Keys. (#1173).
• BREAKING CHANGE: Previously queueSceneUpdate required 2 string arguments, this is now updated with an overloaded method. It either required a list of SceneUpdates or a SceneUpdate object (#1173).
• Markers on the map can now be queried like other features (#1161).
• Feature (and Marker) picking now allows setting a radius to account for pointer size (#1230).
• Added support for label placement parameters: placement, placement_spacing and placement_min_length_ratio (#1211).
• repeat_distance and repeat_group logic now applies to all 'points' styles (#1228).
• dash style parameter now accepts floating point values (#1249).

Fixes

• Fixed application of JS functions in Marker styling (#1201).
• Clarified centroid calculations for degenerate polygons (#1221).
• Fixed some uninitialized variables (#1250).
• Fixed inconsistent parsing of Boolean values between GeoJSON and TopoJSON data sources (#1274).

• A new shader cache improves load times for scenes with lots of custom styles (#1225).
• DataSource has been refactored to better support offline map data (#1014).
• Simplified handling of EGL context loss on Android; this behaves correctly on all devices we've tested but if you notice problems on a very old Android phone when apps resume from pause, let us know and we'll try to help (#1234).
• Refactored label pipeline in preparation for curved label support (#1205).
• Reduced log verbosity (#1259 and #1258).

• Networking now uses OkHTTP 3.5 on Android (#1171).
• BREAKING CHANGE: The setCache method of HttpHandler has been replaced with a new constructor overload, due to changes in OkHTTP 3.0 (#1171).

0.4.0-ios

🎉 This is our very first official iOS release! 🎂

Tangram-es can now be built as a binary framework for integration into your iOS app. Releases for iOS will be available on CocoaPods as the pod 'Tangram-es': https://cocoapods.org/pods/Tangram-es

• The tangram-es framework provides the same set of features as our latest Android release, except for the MapData interface provided on Android.
• Future releases for Android and iOS will indicated with separate tags.
• Releases on either platform with the same minor version number (the 'y' in 'x.y.z') will have approximately the same feature set. For example, 0.4.x-android will have approximately the same feature set as 0.4.y-ios.

0.4.8-android

This is a minor update to the Tangram Android SDK. There are no breaking changes to the Android SDK interface in this release.

Features

• Parsing scene files is now ten times faster on many devices, which will make some scenes load much faster (0e59cf7, tangrams/yaml-cpp#7).
• Loading texture data from image files is slightly faster now (#1170). Tangram-es previously had undocumented support for loading BMP, HDR, PIC, and PNM image files. These formats will no longer work.

Fixes

• Unexpected or missing values in a scene fonts configuration no longer cause crashes (b26e86d).
• Using the "scene update" interface will no longer cause crashes due to JNI environment errors (#1177).
• Point features added to a MapData can now be reliably selected with pickFeature and pickLabel in MapController (#1185).

0.4.7-android

This is a minor update to the Tangram Android SDK. There are no breaking changes to the Android SDK interface in this release.

Fixes

• Non-square bitmaps used with Marker no longer cause visual artifacts or crashes (9ef53db).
• Drawable resources used for Marker are now rasterized at a more appropriate pixel density (3738152).
• Setting a bitmap on a Marker will now immediately update the appearance of the Marker (d9664d2).

0.4.6-android

This is a major update to the Tangram Android SDK. There are no breaking changes to the Android SDK interface in this release.

Features

• Map labels and map features can now be picked separately. MapController now has a new interface for selecting map icons and text labels at a screen position and returning their geographic coordinates
  (#1076).
• A new Marker class provides a convenient way to add and remove individual point, line, and polygon features from the map (#1056).
• Scene loading speed is improved (#1128, #1127, and #1130).

Fixes

• Corrected some potential memory safety issues (#1069).
• Fixed resolution of relative paths in scene imports and resource locations (#1067).
• Prevented 'global' references in scene files from being incorrectly resolved as URLs (#1089)
• Fixed text wrapping for Chinese text (#1075)
• Fixed relative path resolution for files within Android asset bundles (#1083).
• Added checks for malformed scene files during the import process (https://github.com/tangrams/tangram-es/pull/1098/files and #1096).
• Prevented crashes caused by unexpected data in protocol buffers (#1105).
• Fixed vertical texture coordinates for textures used without a sprite atlas (#1142).
• Corrected centroid positions for point placement (#1144).
• Fixed handling of JS functions used in styling when the result of the function is 'null' or 'undefined' (#1117).
