Improvedv1.6.2

Lower-latency receipt validation

App Store and Play server notifications now process with lower latency and stronger replay protection, so entitlements update the moment a purchase clears.

Newv1.5.0

Flutter SDK

One Dart package for iOS and Android joins the native Swift and Kotlin SDKs, with the same paywall, entitlement, and receipt APIs.

APIv1.4.3

Webhooks: entitlement.updated event

A new event fires whenever an entitlement changes, carrying the full prior/next state in the payload. Additive — no breaking changes to existing events.

Fixedv1.4.1

Grace-period edge cases

Resolved grace-period and billing-retry cases so paying users are never briefly locked out while a renewal is being re-attempted.
