Removed unused direct dependency on Symfony HttpKernel to reduce conflicts and improve maintainability (commit cee14c4b7604a33e9fdde541eb286d9d7b88c3c4). Major bugs fixed: - mongo-php-library: Remove Atlas Data Lake (ADL) tests and configurations due to shutdown. Eliminated ADL-related tests/configs to prevent Evergreen/build failures (commit b8f569ec52542d2f1bfca88286f20d14a7f72536). Overall impact and accomplishments: - Strengthened maintainability by removing unnecessary dependencies and obsolete tests; improved documentation integrity; reduced CI risk and build fragility; aligned components with current service lifecycle. Technologies/skills demonstrated: - PHP ecosystem maintenance, documentation refactoring, dependency management, test configuration cleanup, CI/risk mitigation, cross-repo coordination; effective migration from RST to Markdown, disciplined commit messaging.
