4.16.0

Enhancements

• Adds install attribution matching support. If you set up performance marketing integrations on the Superwall dashboard, the SDK will attempt to match the install and track an attribution_match event. The attribution properties will be added to user attributes so that they can be used as breakdowns and filters in the charts.
• Adds support for annual subscriptions that are billed monthly.
• Added EventTrackingBehavior enum and SuperwallOptions.eventTrackingBehavior property for GDPR-compliant event collection control. Use .all (default) to track everything, .superwallOnly to suppress user-initiated tracking, trigger fires, and user-attribute updates while keeping internal SDK events, or .none to stop all event collection entirely. The behavior can also be changed at runtime via Superwall.shared.eventTrackingBehavior.
• Deprecated SuperwallOptions.isExternalDataCollectionEnabled. Setting it to false now maps to .superwallOnly; setting it back to true maps to .all.

Fixes

• Fixes a crash due to concurrent calls to preloadAllPaywalls.
• Fixes an intro offer eligibility mismatch between the paywall and the payment sheet when upgrading/crossgrading/downgrading.
