• Raster tiles no longer cause excessive growth of memory use (#1632).
• Labels using text-shaping are no longer missing their last shaped character (#1637).
• Minor inconsistencies in font face specifications have been corrected (#1641).
• Incorrect extrusions of polygons and other issues as a result of incorrect mixing of polygon style properties has been fixed (#1651).
• Behavior of text labels with no specified font is now consistent with documentation (#1652).
• Relative zip archive import paths within a scene now load correctly. (#1657).
• Longitudes returned by Map functions are now wrapped to the range (-180, 180] (#1663).
• Importing a mixture of relative file paths and HTTP URLs now resolves file paths correctly (#1668).

Android

0.8.0

This is a major update to the Tangram Android SDK and the Tangram iOS SDK. There are breaking changes to both SDK interfaces in this release.

Features

• Data sources can now specify a tms flag to use the TMS interpretation of tile coordinates. (#1595)
• Breaking change: Functions that update the map scene now return a SceneID to identify the new scene. When scene changes are complete, a SceneReadyCallback is run with the same SceneID. This allows an application to prepare the map view immediately before it is displayed. This changes the map initialization interface for both Android and iOS. (#1526)
• Scenes can now be loaded directly from strings of YAML. This is convenient for dynamically combining scene files as a series of imports (example). (#1534 , #1577)
• Curved labels can now be used with more complex scripts. (#1532)
• Cancelled URL requests now produce debug (not error) logs, making logs less verbose. (#1611, #1621)

Fixes

• Invalid scene updates produce more useful error codes. (#1596)
• The text_source draw parameter now correctly handles non-string values. (#1574 , #1575)
• Sprite label collision now uses 'offset' values correctly. (#1623)

Android

• The Android AAR now provides a Proguard configuration to ensure that minification doesn't remove names needed by JNI code. (#1597)
• CachePolicy now provides an interface to control caching for HTTP requests made by the map. (#1587)

iOS

• Breaking change: Public APIs have been revised to follow Cocoa naming conventions. (#1599)
• A build configuration issue occurring with CMake 3.9 is now fixed. (#1589)
• Client applications can now access and configure headers for HTTP requests made by the map. (#1578)
• Map views now re-render as expected after synchronous scene loads. (#1612)

Raspberry Pi

• Several build errors and run-time errors are now fixed and additional command-line options are available. (#1583)

macOS

• Demo app builds are automatically produced for each commit to master and are available to download at: http://ios.mapzen.com (#1606)
• The demo app now has several useful menu shortcuts for opening and editing scene files from your local files. (#1606)

0.7.2

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

Features

• The text_source.left and text_source.right draw rules can now be specified with a JS function (#1531).

• Text line wrapping for labels now behaves correctly for RTL text (#1561).
• Fixed potential crashes in specific uses of Markers with Scene updates (#1546).

0.7.0

This is a major update to the Tangram Android SDK and the Tangram iOS SDK. There are breaking changes to both SDK interfaces in this release.

IMPORTANT:
Beginning with this release, you must supply your own Mapzen API key to build and run the demo applications. You can sign up for a free API key at https://mapzen.com/developers.

For the desktop or iOS demo applications, set the key as an environment variable called MAPZEN_API_KEY in your shell before you run make or cmake to configure the project. For Android, set the key as a Gradle property called mapzenApiKey in your local gradle.properties file (usually ~/.gradle/gradle.properties).

If you are currently using an API key that came with the Tangram ES demo code (i.e. a key that you did not obtain from mapzen.com) that API key will lose access to the Mapzen Tile Services in one month. You should supply your own key for your application before then to prevent disruption of service.

Features

• Enable loading scene files and related files from zip archives (#1373)
• Enable using "default draw rules" in style definitions in a scene file (#1509)
• Add support for tile sources with tile pixel sizes that are powers of 2 greater than 256 (#1498)

Fixes

• Breaking change: Loading a new scene file or updating a scene now clears all Marker objects from the map, preventing Markers from entering inconsistent states (#1467)

Android

• Updated the demo application to include a scene file selection interface (#1470)
• Breaking change: Callbacks for feature queries, map events, and errors now run on the UI thread (#1495)

• The framework version string is now applied to both CFBundleShortVersionString and CFBundleVersion, enabling uploads to the App Store (#1508)

We strongly recommend that iOS applications using version 0.6.0 update to 0.6.1. The 0.6.0 release was built using Xcode 8.3 and will not be accepted to the App Store in the future, due to a bug in that version of Xcode (see the Xcode release notes for details).
