December 2024 — Implemented a critical initialization refactor in woocommerce/sift-for-woocommerce to instantiate Sift_For_WooCommerce after the plugins_loaded hook. This ensures all dependent plugins are loaded before the instance is created, eliminating race conditions during startup and reducing initialization errors. Result: higher reliability for merchant stores, fewer support tickets related to startup failures, and smoother onboarding for ecosystem plugins. The change improves maintainability by aligning with the WooCommerce plugin lifecycle and sets a foundation for future stability in the extension.
