- Improved deployment process with backup creation and verification
- Enhanced error handling and rollback capabilities
- Added comprehensive health checks and service verification
- Improved notification system with better error reporting
- Added links to admin panel and status checks in success notifications
- Implemented multi-step verification for deployment safety
