Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.1.0] - 2025-01-03

Added

  • The SDK now supports storing impression events while the device is offline, ensuring no data loss. These events are batched and seamlessly synchronized with VWO servers once the device reconnects to the internet.

Changed

  • Optimized the MEG rules engine for faster processing.

[1.0.1] - 2024-12-19

Added

  • Added support for changing SDK name and SDK version in hybrid(React-native and Flutter) SDKs.

[1.0.0] - 2024-11-11

Added

  • Added support for Personalise rules within Mutually Exclusive Groups.
  • Settings cache: Cached settings will be used till it expires. Client can set the expiry time of cache.
  • Storage support: Built-in local storage will be used by default if client doesn't provide their own. Client’s storage will be used if it is provided.
  • Call backs added to avoid busy waiting for server call to complete.
  • Changed variable access to method access for Flag - setIsEnabled & isEnabled

[0.1.0] - 2024-07-31

Added

  • First release of VWO Feature Management and Experimentation capabilities.

        // Track the event for the given event name and context
        val properties = mutableMapOf<String, Any>("cartvalue" to 10)
        vwo.trackEvent("vwoevent", userContext, properties)

        // send attributes data
        vwo.setAttribute("attribute-name", "attribute-value1", userContext)
    }

    override fun vwoInitFailed(message: String) {
        Log.d("Vwo", "vwoInitFailed: $message")
    }
})

  • Error handling

    • Gracefully handle any kind of error - TypeError, NetworkError, etc.
