Changed
  • Pinned native SDKs are now Appstack iOS SDK 4.6.0 and Appstack Android SDK 1.8.0. Platform floors are unchanged: iOS 15.0+ and Android API level 21+.
  • Custom event parameters are encrypted on the device before being sent. Parameter names that must stay readable, such as currency and revenue, are excluded through a server-controlled list, so revenue reporting is unchanged. On-device encryption requires iOS 17 or newer; iOS 15 and 16 encrypt server-side as before.
  • The pinned iOS SDK ships an Apple privacy manifest declaring its required-reason API usage.
Fixed
  • On iOS, an event whose parameters hold null is no longer dropped, and a parameter value JSON cannot represent no longer crashes the app. Those keys are dropped individually and the event still sends.

Changed
  • OpenUPM releases now use a Unity-signed .tgz created with a pinned, checksum-verified Unity UPM CLI. Unity 6.3 and newer can verify the package’s publisher and integrity instead of showing the missing-signature warning.

Added
  • Optional scene-independent auto-initialization configured through Edit → Project Settings → Appstack, with separate development and production keys for iOS and Android, per-platform enablement, automatic or pinned environment selection, explicit production-key fallback for development builds, and target-specific pre-build validation.
  • Idempotent Unity-side configuration: the first successful automatic or manual configuration wins, identical repeats are silent, conflicting repeats warn without exposing credentials, and failed attempts remain retryable.

Added
  • SetCustomerUserId(customerUserId) and ClearCustomerUserId() for setting or clearing the customer user ID after Configure(), bridging the native iOS/Android setter of the same name. Use them when a login reveals the ID: a repeat Configure() is a no-op and ignores its customerUserId. null, an empty string, and whitespace all clear the stored ID, so ClearCustomerUserId() is the explicit spelling of SetCustomerUserId(null) rather than separate behavior. This differs from Configure(), where an empty customerUserId means “not provided” because it never clears.
Changed
  • Pinned native SDKs are now Appstack iOS SDK 4.5.0 (from 4.4.0) and Appstack Android SDK 1.7.0 (from 1.5.0). Platform floors are unchanged: iOS 15.0+ and Android API level 21+.
  • SendEvent(EventType.INSTALL) is a no-op. EventType.INSTALL is emitted automatically by the native SDKs on first launch, and both new pinned versions discard a manually sent INSTALL; the previous pins accepted it.
