*** WooCommerce Fraud Protection Changelog ***

2026-07-03 - version 0.1.5
* Fixed - Fatal error in cart event tracking on stores that allow decimal product quantities; quantity tracking now supports whole and fractional values.
* Updated - Cart event tracking callbacks now fail open and log unexpected errors instead of interrupting shopper requests.
* Updated - Require PHP 8.1 or newer; on older PHP versions the plugin safely skips loading instead of activating.
* Updated - Modernized the codebase with PHP 8.1 enums and readonly data objects; public interfaces and filters now use typed enums (e.g. FraudDecision) in place of decision strings.

2026-07-01 - version 0.1.4
* Added - Reporting interface for payment outcomes (payments, disputes, refunds).
* Fixed - Skip fraud verification on classic checkout submissions that already failed WooCommerce validation, avoiding unnecessary processing.
* Fixed - Throttle repeated plugin startup warnings (e.g. on unsupported WooCommerce versions) to once per day instead of once per request.
* Updated - Persist the fraud session identifier on guest orders placed without a browser session so outcomes track consistently.
* Updated - Substantial internal refactoring across the plugin, including a new dependency-injection architecture and WooCommerce-core-aligned namespaces, for long-term maintainability.

2026-05-17 - version 0.1.3
* Updated - Update init logic to match the latest changes in Blackbox SDK.
* Updated - Reduce Blackbox request timeouts to 3 seconds (browser SDK and server-side verify/report calls) to bound worst-case checkout latency.
* Updated - Harden plugin startup so missing dependencies (autoloader, WooCommerce Blocks classes, optional checkout schemas) fail open instead of producing a fatal.
* Added - Optional PHP error log forwarding for selected operational events (transport failures, response parsing failures, third-party filter failures) with a strict context-key allowlist.

* Fixed - Broken asset URLs when the plugin file is located outside of WP_CONTENT_DIR
* Updated - Switch to PSR-4 autoloading to load files only when needed
