🚀 Highlights

Redis 8.4 Support

Added support for Redis 8.4, including new commands and features (#3572)

Typed Errors

Introduced typed errors for better error handling using errors.As instead of string checks. Errors can now be wrapped and set to commands in hooks without breaking library functionality (#3602)

New Commands

• CAS/CAD Commands: Added support for Compare-And-Set/Compare-And-Delete operations with conditional matching (IFEQ, IFNE, IFDEQ, IFDNE) (#3583, #3595)
• MSETEX: Atomically set multiple key-value pairs with expiration options and conditional modes (#3580)
• XReadGroup CLAIM: Consume both incoming and idle pending entries from streams in a single call (#3578)
• ACL Commands: Added ACLGenPass, ACLUsers, and ACLWhoAmI (#3576)
• SLOWLOG Commands: Added SLOWLOG LEN and SLOWLOG RESET (#3585)
• LATENCY Commands: Added LATENCY LATEST and LATENCY RESET (#3584)

Search & Vector Improvements

• Hybrid Search: Added EXPERIMENTAL support for the new FT.HYBRID command (#3573)
• Vector Range: Added VRANGE command for vector sets (#3543)
• FT.INFO Enhancements: Added vector-specific attributes in FT.INFO response (#3596)

Connection Pool Improvements

• Improved Connection Success Rate: Implemented FIFO queue-based fairness and context pattern for connection creation to prevent premature cancellation under high concurrency (#3518)
• Connection State Machine: Resolved race conditions and improved pool performance with proper state tracking (#3559)
• Pool Performance: Significant performance improvements with faster semaphores, lockless hook manager, and reduced allocations (47-67% faster Get/Put operations) (#3565)

Metrics & Observability

• Canceled Metric Attribute: Added 'canceled' metrics attribute to distinguish context cancellation errors from other errors (#3566)
