We are using revenue cat in observer mode inside our Unity3d project (Unity 2021.3.29f1). Google requires to update to billing client 6. Unity already created InAppPurchasing plugin with BC 6 (4.12.0). But as I see in purchases-unity/VERSIONS.md at main · RevenueCat/purchases-unity (github.com) there is still no version that supports both billing client 6 and observer mode with Unity iAP?

When new version will be released? We need it ASAP because our deadline is august 31 of this (2024) year.
