This release introduces major support for Redis 8.6 features like Idempotent Producers and HOTKEYS, alongside comprehensive OpenTelemetry metrics integration. It also brings significant stability improvements, particularly around Redis Enterprise Cluster maintenance notifications and connection handling.

Migration Steps

✨ New Features

  • Added support for Redis 8.6, including new commands and features for streams idempotent production and HOTKEYS.
  • Introduced comprehensive support for Redis Enterprise Cluster maintenance notifications via SMIGRATING/SMIGRATED push notifications, including automatic slot migration handling (relaxing timeouts during SMIGRATING and triggering cluster state reloads upon SMIGRATED).
