This latest release updates the SDK to use BillingClient 6. This version of BillingClient brings little change compared with BillingClient 5 which brought an entire new subscription model which resulted in large changes across the entire SDK.
The only modification at the API level involves replacing "ProrationMode" with "ReplacementMode". The specific replacement modes remain unchanged.
If your app doesn't currently use DEFERRED replacement modes, then you should be safe to upgrade to this version without changes in behavior.
If your app supports product changes using [DEFERRED replacement mode](🔗), then you can either stick with the previous major version until support for DEFERRED is re-introduced in this major version, or you can remove DEFERRED replacement options from your app.
