May 2026 monthly summary for shopware/shopware focused on delivering architectural improvements, reliability, and test quality that enable faster feature delivery with lower risk. Key outcomes: - Commercial License Provisioning Webhook: replaced the legacy license sync with a new event-driven webhook for commercial licenses; introduced event handling to react to license changes; deprecated legacy methods/classes to streamline the service. - App Lifecycle Management and Persistence Overhaul: centralized state changes via lifecycle persisters, integrated MCP persistence (McpPersister), introduced AppManager, and added custom entity lifecycle handling and feature validation; reduced coupling and legacy synchronization patterns. - Webhook Cache Invalidation on App Write: added APP_WRITTEN_EVENT listener to clear webhook cache when an app is written, with tests ensuring correct event subscription. - Testing Improvements and Cleanup: expanded coverage and readability for app lifecycle components and persisters; cleaned up tests, removed unused imports, refined assertions, and reorganized test suites for robustness. Business value and impact: - Improved reliability and scalability of lifecycle and licensing workflows, enabling safer deployment of app-related changes. - Reduced technical debt through deprecation of legacy paths, explicit lifecycle management, and better test coverage, supporting faster, safer feature delivery. - Demonstrated breadth of skills across event-driven design, persistence architecture, code cleanup, and test strategy.
