M1 Mac Simulator Support

It's possible to build and run your Sentiance integrated app on an M1 Mac simulator, with the use of our custom TensorFlowLiteC framework. See this guide.

[5.15.0] - 13 July 2022

Added

  • Support for arm64 (M1 Mac) simulators. See this guide.

Changed

  • The TensorFlowLiteC framework bundled in our fat framework and xcframework artifacts have been replaced with a custom TensorFlowLiteC v2.7.0 framework, which includes support for arm64 (device), arm64 (simulator), and x86_64 (simulator) architectures.

Fixed

  • Failure to clean up the keychain under certain circumstances, after app reinstallation. This resulted in restoring the previous Sentiance user on the device.

  • Failure to run the vehicle crash detector when triggered-trips mode is enabled on the SDK.

Removed

  • Support for armv7 (device) and i386 (simulator) architectures.

[5.14.1] - 4 July 2022

Added

  • API to control background task identifier registration (details). This is currently relevant only when the SDK's step-counter feature is being utilized.

Changed

  • Improved the vehicle crash detection algorithm.

Fixed

  • An issue that was introduced in v5.14.0, where iOS terminates the app when scheduling a background task. This was caused by the SDK registering background task identifiers outside of the app delegate.

[5.14.0] - 30 May 2022

This release updates the SDK's TensorFlow Lite dependency version to 2.7.0. If your app depends on a different version of TensorFlow Lite, make sure to test it for compatibility before updating.

Changed

  • Updated the TensorFlow Lite dependency to v2.7.0.

  • Updated the vehicle crash detection ML model for TensorFlow Lite v2.7.0 compatibility.

[5.13.0] - 5 May 2022

Added

  • Step count tracking (disabled by default).

  • Support scheduling background tasks.

Changed

  • Improved the vehicle crash detection algorithm.

[5.12.1] - 3 Feb 2022

Changed

  • Improved the vehicle crash detection algorithm.

  • Added support for vehicle crash detection when motion activity permission is not granted.

Fixed

  • A bug that was introduced in v5.11.2, where reinstalling the app did not clear the previous Sentiance user.

[5.12.0] - 4 Jan 2022

Fixed

  • Trip recording consistency upon unexpected app restart.

  • Stability of background task usage in the SDK.

  • Improved vehicle crash detection.

  • Inability to detect trips after toggling the location precision setting on iOS 14+.

Deprecated

  • Legacy on-device trip profiling. This feature will be removed in the next major release.

[5.11.2] - 8 Nov 2021

Fixed

  • Fixed updating debug log configuration received from backstage.

  • Removed obsolete linker flag '-all_load' from podspec which lead to linker issues in recent react native environments.

[5.11.1] - 29 Jul 2021

Fixed

  • Fixed an issue where detections were not able to start on iOS 15 devices due to the updated authorization status.

  • Fixed TensorFLowLite model updating mechanism at runtime.

  • Removed embedded TensorFlowLite library from SENTSDK pod by providing a separate thinned package and adding a pod dependency to TensorFlowLite (applies to CocoaPods integration only and requires CocoaPods 1.10.0 **** or above).

[5.11.0] - 16 Jul 2021

Added

  • Support SDK artifacts without CallKit linkage

Fixed

  • Fixed rare and transient runtime crashes when object references inside the SDK get released from the OS due to erroneous reference semantics.

  • Fixed delayed uploading of payloads in case of outdated authentication tokens.

  • Fixed missing trip detections due to erroneous flip flop checks.

[5.10.1] - 20 May 2021

Changed

  • Updated embedded TensorFlowLite framework to v2.4.0.

Fixed

  • Fixed potential accelerometer data gaps in trip objects due to included data from previous trips.

  • Fixed swift compiler warning since Xcode 12.5 wrt a missing include in the umbrella header.

[5.10.0] - 14 Apr 2021

Added

  • Support for approximate location access available since iOS 14.

  • Support for detection of screen lock/unlock events.

Changed

  • Add fail-fast mechanism during third party user linking if linking has not been completed.

  • Slightly adjust the actual stationary start time in the same way as the Android SDK.

Fixed

  • Missing sensor data for crash events in some cases.

  • Overlapping stationary events in case of trip timeouts.

  • Recovery of trip object creation in case the SDK got killed by the OS.

  • Trip object creation and submission in case of a crash event.

[5.9.0] - 29 Jan 2021

Added

  • New type to SDK artifacts which are now packaged as both Framework and XCFramework (Please make sure to have CocoaPods 1.10.0 or above installed on your machine if you integrate Sentiance SDK via CocoaPods).

  • An improved and more accurate vehicle crash detection, backed by a machine learning model. You must switch to using the new Sentiance API method setVehicleCrashHandler: to activate it.

  • A new method to help test your crash detection integration. See invokeDummyVehicleCrash.

  • A new method to check if crash detection is supported on the device for a specific trip type. See isVehicleCrashDetectionSupported:.

Beta Feature: Support for host apps that enable Data Protection. This functionality is released as a beta feature and not yet recommended for production use.

Changed

  • The trip serialization process utilizes a less intense and more optimized background processing model.

Deprecated

Fixed

  • An issue where portions of accelerometer and gyroscope data might be missed

  • An issue where stationary detection might overlap with past stationary and trip detections

  • An issue where the SDK might continuously report an initialization state of SENTInitInProgress after the initialization credentials are changed

  • An issue where the SDK might continue collecting location fixes even after the user becomes stationary and cause excessive energy consumption

  • An issue where the SDK might accidentally remove keychain items owned by the host app

  • An issue where the SDK might crash during a network operation

Removed

  • Location permission prompt when starting the SDK. If you rely on the SDK for prompting the user, please make sure you update your app and prompt the user during the onboarding.

Fixed

  • The SQLCore I/O database error

  • High frequency GPS configuration

Fixed

  • An issue when using beacon regions was causing unexpected exits

[5.7.0] - 3 Jun 2020

Added

[5.6.0] - 5 Feb 2020

Added

  • Support for resetting the SDK to factory settings, which clears all user data and allows creating a new Sentiance user**.**

Changed

  • The geo-fence management policy so that the SDK does not intervene with the lifecycle of geo-fences owned by the enclosing app.

  • Removed the motion activity permission prompt when starting the SDK. If you rely on the SDK for prompting the user, please make sure you update your app and prompt the user during the onboarding.

Fixed

  • An issue where the SDK database might experience conflicts when the enclosing app also uses database instance(s) of CoreData.
