+Chore
+* Include latest chargebee-android (`2.0.0-beta-6`) with upgraded billing client lib to v8.3.0
+* Android compile/target SDK version raised to 34
+* Kotlin 2.1.21, AGP 7.4.2, Gradle 7.6.4, JDK 17

+Breaking
+* Android minimum SDK version raised from 21 to 23 (required by Google Play Billing Library 8)
+* On Android, `restorePurchases` no longer returns fully expired subscriptions, even when `includeInactivePurchases` is true. Google Play Billing 8 removed the purchase history API and offers no client-side replacement, so only active subscriptions can be restored, including those that are cancelled but not yet expired, paused, in trial, or suspended. iOS is unaffected.

 To retrieve **inactive** purchases along with the **active** purchases for your app user, you can call the `restorePurchases()` function with the `includeInactivePurchases` parameter set to true. If you only want to restore active subscriptions, set the parameter to false. Here is an example of how to use the restorePurchases() function in your code with the `includeInactivePurchases` parameter set to true.
 
+> [!IMPORTANT]  
+> `restorePurchases()` restores subscriptions only; one-time products are never restored. On Android, Google Play Billing Library 8 removed the purchase history API and provides no client-side replacement, so only subscriptions that Google Play still associates with the user's account can be restored: active ones, including those that are cancelled but not yet expired, paused, in trial, or suspended. Subscriptions that have fully expired are no longer returned, even when `includeInactivePurchases` is set to `true`. iOS is unaffected.
