Improved tracking fidelity on backgrounds and bright lighting
More accurate shape and scale for hands
Significantly improved performance on embedded “Rigel” devices
LeapC is now the officially supported API included in the SDK. LeapAPI has been deprecated
Changed the fingertip location in LeapC applications such that the point defines the center of a sphere whose edge is at the fingertip. Previous output was defined such that the point was at the edge of the fingertip
Removed LeapCSharp and associated functionality from the SDK. It can now be found as part of UnityModules
Removed Leap.dll, all associated language bindings (LeapPython, LeapJava, Objective-C) and samples
Added a feature that pauses the device when no clients are connected (note: the Leap Control Panel is a client)
LeapC makefile now generates all the samples correctly
Fixed a hang at service shutdown
Fixed an issue where hands could initialize on top of other hands
Greater robustness to cluttered backgrounds and ambient light interference
Enhanced tracking range that extends to the full length of your arms
Faster and better initialization for all hands
Lower latency
Significantly improved grab-and-drop interactions
Lower overall CPU usage
Much better finger flexibility allowing for better poses
Better tracking on the edge of the field of view
Added a VR and PC visualizer to the tray menu
Various control panel updates
The Unity assets now use a C# binding to a C-language library rather than the SWIG-generated C++ bindings. The new C# API is slightly different then the previous one, especially for images. Currently this new C# API is only used in Unity
Deprecated Tools
Deprecated Gestures
Deprecated Motion APIs (Frame and Hand translation, rotation, scale and related probability estimates)
Tracking now automatically resumes after recalibration on Windows
Added the setPaused() API
Added the isLightingBad() API
Added the isSmudged() API
Added onLogMessage API to LeapListener
A new ‘start_paused’ config flag has been added
Fixed touch compatibility for Recalibrate
Fixed Recalibrate not being resizable
Improved behavior when detecting smudges
Apps should now always correctly detect reconnection
Updated the C++ sample with examples of the new APIs
