12:16:09 +0100 Subject: [PATCH 2/2] feat: implement comprehensive API versioning system Implements all 5 steps of API version management: Step 1: Versioning Strategy - VersionManager class for semantic versioning (major.minor.patch) - Support for 4 versioning strategies: header, URL path, query param, hybrid - Automatic version extraction and validation - Endpoint registration and version history tracking Step 2: Backward Compatibility - CompatibilityManager for automatic request/response transformations - Field mapping and schema evolution support - Compatibility adapters between versions - Automatic shim generation Step 3: Documentation & Deprecation - DeprecationManager for tracking deprecated features - Migration path documentation - Severity levels (warning/critical) - Warning suppression and logging Step 4: Analytics & Monitoring - AnalyticsManager for usage metrics and adoption tracking - Request/response time monitoring - Error rate tracking by version - Migration success rate calculation - CSV/JSON export capabilities Step 5: Sunset Management - SunsetManager for version lifecycle management - Sunset policies with communication phases - Decommissioning step automation - Alternative version suggestions Additional Features: - MigrationManager for automated data migrations - 226 test cases with 100% passing rate - 1,650+ lines of comprehensive documentation - 7 practical code examples - Full TypeScript type support - Global instances for convenient usage Tests: npm run test -> 226 tests passed Files Added: -
