🚀 Highlights

Redis 8.8 Support

This release adds support for Redis 8.8. The README's supported-versions list now includes Redis 8.8 alongside 8.0/8.2/8.4, and CI exercises the 8.8 client-libs-test image across the full suite (Makefile, build workflow, doctests, run-tests action, and docker-compose).

Coverage for the new commands that ship in the 8.x line, rounded out in this release:

• AR* array data type (#​3813) — new array data structure, exposed via the ArrayCmdable interface (see the experimental-features highlight below).
• INCREX (#​3816) — atomic increment with expiration in a single round-trip.
• XNACK (#​3790) — explicit negative-acknowledge of pending stream entries.
• XAUTOCLAIM PEL deletes (#​3798) — XAUTOCLAIM/XAUTOCLAIMJUSTID now return the list of deleted message IDs from the pending entries list.
• TS.RANGE multiple aggregators (#​3791) — TS.RANGE/TS.REVRANGE/TS.MRANGE/TS.MREVRANGE accept multiple aggregators in a single call.
• Z(UNION|INTER|DIFF) COUNT aggregator (#​3802) — COUNT reducer for sorted-set set operations.
• JSON.SET FPHA (#​3797) — new FPHA argument that specifies the floating-point type for homogeneous FP arrays.

Stable RESP3 for RediSearch (UnstableResp3 deprecated)

FT.SEARCH, FT.AGGREGATE, FT.INFO, FT.SPELLCHECK, and FT.SYNDUMP now parse RESP3 (map) responses into the same typed result objects as RESP2 — Val() and Result() work uniformly on both protocols, no flag required. Previously, RESP3 search responses required UnstableResp3: true and were returned as opaque maps accessible only via RawResult() / RawVal().

As a result, the UnstableResp3 option is now a no-op across every options struct (Options, ClusterOptions, UniversalOptions, FailoverOptions, RingOptions) and has been marked // Deprecated:. The field is retained for backwards compatibility — existing code that sets UnstableResp3: true will continue to compile and behave identically — but it will be removed in a future release and new code should not set it. RawResult() / RawVal() continue to work for callers that prefer the raw RESP payload.

Experimental Array Data Structure Commands

Adds an experimental ArrayCmdable interface with the AR* command family (ARSet, ARGet, ARGetRange, ARMSet, ARMGet, ARDel, ARDelRange, ARScan, ARSeek, ARNext, ARLastItems, ARGrep, ARGrepWithValues, ARInfo/ARInfoFull, and typed reducers AROpSum/AROpMin/AROpMax/AROpAnd/AROpOr/AROpXor/AROpMatch/AROpUsed) for working with Redis 8.8's new array data type. API is experimental and may change in a future release.

✨ New Features

• RESP3 search parser: First-class RESP3 parsing for FT.SEARCH/FT.AGGREGATE/FT.INFO/FT.SPELLCHECK/FT.SYNDUMP responses with backwards compatibility for RESP2 (#​3741) by @​ndyakov
• INCREX: New INCREX command support — atomic increment with expiration (#​3816) by @​ndyakov
• XNACK: Client support for the XNACK stream command for explicitly negative-acknowledging pending entries (#​3790) by @​elena-kolevska
• TS range multiple aggregators: TS.RANGE/TS.REVRANGE/TS.MRANGE/TS.MREVRANGE now accept multiple aggregators in a single call (#​3791) by @​elena-kolevska
• XAutoClaim deleted IDs: XAUTOCLAIM/XAUTOCLAIMJUSTID now return the list of deleted message IDs from the PEL (#​3798) by @​Khukharr
• JSON.SET FPHA: JSON.SET accepts a new FPHA argument that specifies the floating-point type for homogeneous floating-point arrays (#​3797) by @​ndyakov
• Sorted-set union/intersection COUNT: ZUNION/ZINTER/ZDIFF aggregator now supports COUNT (#​3802) by @​ofekshenawa
• FT.HYBRID vector validation: Validates hybrid-search vector input types and adds proper typed vector parameters (#​3756) by @​DengY11
• Cluster pool wait stats: ClusterClient.PoolStats() now accumulates WaitCount and WaitDurationNs across all node pools (previously always zero) (#​3809) by @​LINKIWI

🐛 Bug Fixes

• TLS-only Cluster PubSub: CLUSTER SLOTS port-0 entries now fall back to the origin endpoint's port, fixing dial tcp <ip>:0: connection refused on TLS-only clusters started with --port 0 --tls-port <port> (fixes #​3726) (#​3828) by @​ndyakov
• Sharded PubSub reconnect routing: PubSub.conn() now passes both regular (c.channels) and sharded (c.schannels) channels into the per-PubSub newConn closure. Previously, ClusterClient.SSubscribe-only PubSubs reconnected to a random node (because the routing closure saw an empty channel list), the SSUBSCRIBE was sent to the wrong shard, and the resulting MOVED reply was silently dropped (#​3829) by @​ndyakov
• ClusterClient Watch retry: User errors returned from a Watch callback are no longer subjected to cluster-retry classification; transient cluster errors still retry, but a callback returning e.g. net.ErrClosed short-circuits immediately (#​3821) by @​obiyang
• Sentinel concurrent-probe leak: MasterAddr's concurrent sentinel probe now closes the non-winning sentinel clients instead of leaking them (#​3827) by @​cxljs
• Sentinel rediscovery loop on master-only setups: replicaAddrs no longer tears down the cached sentinel client when the replica list is empty, eliminating a continuous rediscovery loop on master-only Sentinel deployments that flooded logs and added per-operation latency (#​3795) by @​shahyash2609
• Pool CloseConn hooks: Pool.CloseConn now triggers registered hooks, fixing a memory leak when connections are closed explicitly rather than via the normal removal path (#​3818) by @​ndyakov
• Dial TCP error redirection: Wrapped dial tcp errors are now correctly classified as redirectable so cluster routing can recover from a single unreachable node (#​3810) by @​vladisa88
• Pool Close health checks: ConnPool.Close now only runs health checks against idle connections, avoiding spurious activity on connections still in use (#​3805) by @​ndyakov
• VLinks return type: Fixed the return type of VLINKS/VLINKSWITHSCORES vector-set replies (#​3820) by @​romanpovol

🧪 Testing & Infrastructure

• Flaky tests: Stabilized several flaky tests in the sentinel and pool suites (#​3815) by @​ndyakov
• Sentinel failover metric race: Fixed a data race in the sentinel failover metric test (#​3824) by @​cxljs
• waitForSentinelClusterStable post-conditions: The sentinel test harness now waits for replicas to be fully connected (not just present in the count) and is robust to randomized spec ordering after failover specs, eliminating an intermittent Expected master to equal slave flake (#​3830) by @​ndyakov
• govulncheck workflow: New scheduled GitHub Actions workflow runs govulncheck on every push, PR, and weekly, surfacing newly disclosed Go vulnerabilities even when no code changes (#​3779) by @​solardome
• CI Redis 8.8-rc1: CI now exercises the 8.8-rc1 Redis image (#​3814) by @​ofekshenawa

🧰 Maintenance

• Cmd.Slot() lookup refactor: Caches the per-command CommandInfo and short-circuits keyless commands before the switch dispatch, removing redundant Peek calls (#​3804) by @​retr0-kernel
• stdlib math/rand: Replaced internal/rand with math/rand from the standard library now that the minimum Go version is 1.24 (#​3823) by @​cxljs
• ConnPool queue channel: Removed the unused queue channel from ConnPool, trimming the pool's footprint (#​3826) by @​cxljs
• Extra packages LICENSE: Added a LICENSE file to each extra/* package (#​3817) by @​ndyakov
• README & CI image: Documentation refresh and bumped the default CI image tag (#​3822) by @​ndyakov
