+The first release candidate of **RevenueCat Purchases React Native v6** is here!! 😻
+
+This latest release updates the Android SDK dependency from v5 to [v6](https://github.com/RevenueCat/purchases-android/releases/tag/6.0.0) to use BillingClient 5. This version of BillingClient brings an entire new subscription model which has resulted in large changes across the entire SDK.
+
+### Migration Guides
+- See [Android Native - 5.x to 6.x Migration](https://www.revenuecat.com/docs/android-native-5x-to-6x-migration) for a
+  more thorough explanation of the new Google subscription model announced with BillingClient 5 and how to take
+  advantage of it in V6. This guide includes tips on product setup with the new model.
+
+### New `SubscriptionOption` concept
+
+#### Purchasing
+In v5, a Google Play Android `Package` or `StoreProduct` represented a single purchaseable entity, and free trials or intro
+offers would automatically be applied to the purchase if the user was eligible.
+
+Now, in React Native v6, an Google Play Android `Package` or `StoreProduct` represents a duration of a subscription and contains all the ways to
+purchase that duration -- any offers and its base plan. Each of these purchase options are `SubscriptionOption`s.
+When passing a `Package` to `purchasePackage()` or `StoreProduct` to `purchaseStoreProduct()`, the SDK will use the following logic to choose which
+`SubscriptionOption` to purchase:
+- Filters out offers with "rc-ignore-offer" tag
+- Uses `SubscriptionOption` with the longest free trial or cheapest first phase
+    - Only offers the user is eligible will be applied
+- Falls back to base plan
+
+For more control, purchase subscription options with the new `purchaseSubscriptionOption()` method.
+
+#### Models
+
+`StoreProduct` now has a few new properties use for Google Play Android:
+- `defaultOption`
+  - A subscription option that will automatically be applie when purchasing a `Package` or `StoreProduct`
+- `subscriptionOptions`
+  - A list of subscription options (could be null)
+
+### Observer Mode
+
+Observer mode is still supported in v6. Other than updating the SDK version, there are no changes required.
+
