SDK version 11.1.0 for iOS and Android introduces a feature that allows developers to customize the grouping of handled errors and exceptions for easier debugging. By using a custom grouping string added from the SDK, Luciq can create a hash of this string to serve as a fingerprint, grouping non-fatal errors like bad network requests or database errors. This approach helps in reducing noise, making it easier to debug and fix issues efficiently. For implementing this feature, developers can refer to the documentation provided for both iOS and Android platforms.
