 All notable changes to this package will be documented in this file.
 
+## [Unreleased]
+
+### Fixes
+* `SuperwallEventInfo.EventType` was never populated: iOS serialized `String(describing: event)`, which on SuperwallKit versions without a `CustomStringConvertible` conformance dumps the case together with its associated values (`transactionComplete(transaction: ..., product: ...)`), and Android sends the snake_case `rawName` (`transaction_complete`). Neither matched the `EventType` enum, so every delegate event arrived as the default `FirstSeen` and any `switch` on it was dead. iOS now emits only the case name, and the C# parser accepts both camelCase and snake_case, logging a warning instead of failing silently when a name is still unknown. `EventType` gains the members both native SDKs already emit but C# lacked (`PaywallPageView`, `TestModeModalOpen`/`Close`, `CelExpressionResult`, `ErrorThrown`, `ReviewGranted`/`Denied`, `AttributionMatch`, `StripeCheckoutStart`/`Submit`/`Complete`/`Fail`), and the two placement names whose member is spelled differently (`deepLink_open` → `DeepLink`, `paywallWebviewLoad_processTerminated` → `PaywallWebviewProcessTerminated`) are mapped explicitly.
