[dependabot]

Bumps github.com/redis/go-redis/v9 from 9.19.0 to 9.20.0.

Release notes

Sourced from github.com/redis/go-redis/v9's releases.

9.20.0

🚀 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.

CI image bump (#3814) by @​ofekshenawa. Command coverage contributions by @​cxljs, @​elena-kolevska, @​Khukharr, @​ndyakov, and @​ofekshenawa.

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
