5.11.0 Release Changelog

🌟 Highlights

Smart Client Handoffs for Enterprise OSS API (Pending a Redis Enterprise version release)

This release introduces support for Redis Enterprise Cluster maintenance notifications via SMIGRATING/SMIGRATED push notifications. The client now automatically handles slot migrations by:

• Relaxing timeouts during migration (SMIGRATING) to prevent false failures
• Automatic slot handoff when completed (SMIGRATED)
• Enabling seamless operations during Redis Enterprise maintenance windows

Redis 8.6 Support

This release adds support for Redis 8.6 features:

• XADD idempotency options (IDMPAUTO, IDMP, and policy) - Prevent duplicate entries by tracking producer and message IDs
• XCFGSET command - Configure per-stream idempotency parameters (IDMP_DURATION, IDMP_MAXSIZE)
• XINFO STREAM enhancements - New idempotency tracking fields (idmp-duration, idmp-maxsize, pids-tracked, iids-tracked, iids-added, iids-duplicates)
• HOTKEYS command family (START, STOP, GET, RESET) - Track and identify hot keys by CPU time and network bytes
