This release introduces comprehensive support for Redis maintenance notifications, enabling applications to handle server maintenance events gracefully. The new maintnotifications package provides:

  • Connection Handoff: Automatic connection migration during server maintenance with configurable retry policies and circuit breakers
  • Graceful Degradation: Configurable timeout relaxation during maintenance windows to prevent false failures
  • Event-Driven Architecture: Background workers with on-demand scaling for efficient handoff processing

For detailed usage examples and configuration options, see the maintenance notifications documentation.
