January 2025 - Changes in SDK versioning semantics

We have changed our SDK versioning scheme to better adhere to the semantic versioning principle. This will make it easier for you to determine the nature of the SDK release in use in your projects.

  • UPDATE: The minimum required version of Android Gradle Plugin (AGP) has been raised to 8.6.0, the minimum required Gradle version to 8.7, and the minimum supported JDK version is 17. (NEVISACCESSAPP-6817). This is due to several reasons:
    • The new minimum API level requirements in Google Play Store is 35, which imposes the use of AGP 8.6.0.
    • AGP 8.6.0 imposes the use of Gradle 8.7 (or later) of JDK 17 (or later).
    • We must use the latest version of GSON to fix a CVE. This version requires JDK 17 or later.

Flutter plugin 3.7.0 - 12.07.2024​

General changes and new features​

Android 6 / API Level 23 deprecated

As of Flutter plugin 3.7.0, Android API level 23 support is deprecated.

  • CHANGED: We updated the minimum supported SDK version to Dart 3.1.0.
  • CHANGED: We updated Nevis Mobile Authentication SDK to version 3.7.0.
  • NEW: A new MetaData API to retrieve Nevis Mobile Authentication SDK version and other platform-dependent information is available. For applications running on Android, the API retrieves the SHA-256 hash of the signing certificate of the application that includes the SDK. For iOS applications, the API provides the FacetId of the application that includes the SDK.
  • NEW: A new experimental API to retrieve pending out-of-band operations has been added.

Breaking Changes​

  • NEW: A new alphanumeric Password Authenticator is available. Note that this requires the nevisFIDO 8.2405.0 component version, otherwise you will need to manually extend the metadata and policy configuration files in nevisFIDO to support this new authenticator type. In this case refer to Default Nevis Authenticator Metadata to obtain the metadata statements and don't forget to add the authenticator AAIDs to the policy file(s). This is classified as a breaking change as depending on your implementation you may need to adapt your code when filtering or listing the available authenticators. (NEVISACCESSAPP-5406)

For more information, see API references.
