What's Changed

• v4: a close with commands in flight no longer completes a call with another call's reply (#3329) by @mgravell in #3332
• LATENCY RESET and CLIENT TRACKING write through IRespArgument operands, and RenderedArgs goes by @mgravell in #3327
• The coverage audit sees v4's RespLiterals fragments and ignores the connection core; CLIENT SETNAME/SETINFO get ledger rows by @mgravell in #3328
• v4: cache hits reuse the deserialized result for provably-shareable types by @mgravell in #3349

• Check the maximum operation count in HeartbeatConsistencyCheckPingsAsync by @unsafePtr in #3342
• Links follow the org move to seredis (#3326) by @mgravell in #3344
• MOVING handoff: hold new work in the backlog while the in-flight commands drain, so the recycle happens within a round trip instead of at the window end by @mgravell in #3347

New Contributors

V4 preview. Since 4.0.146-alpha:

• high-integrity mode restored — a sequence check behind every command (#3308)
• client-side caching replaces a TimeToLive-expired entry on the next fill rather than waiting for the sweep (#3318, #3320)
• an ASK re-send keeps CLIENT CACHING out of the prefix and exempts ASKING from the sequence check (#3319)
• cluster failover recovery — the library's own topology refresh is exempt from the AllowAdmin gate, a replica-write refusal marks the slot map suspect, and losing an established connection prompts a reconfigure (#3324, from the #3323 investigation)
• the connect wait covers the eagerly-dialled subscription connection (#3325)
• HOTKEYS and CLIENT KILL write through IRespArgument operands (#3321)
• plus main merged in up to 3.4.29 (#3322)

What's Changed

• (stabilty) Reset a CycleBuffer segment's start trim when it is recycled (#3302) by @mgravell in #3303
• Restore: make the dedicated subscription connection lazy by @mgravell in #3310
• Update RedisType.Bitmap and the keyspace-event tokens to reflect current server values by @mgravell in #3312
• Fix ConnectionGroupMember string-ctor dropping the name by @mgravell in #3314
• Parse unbracketed IPv6 ip:port from the server (#1422) by @mgravell in #3307
• Profile commands sent in a batch (#2175) by @mohsinaliwork686-rgb in #3313

Tooling

• gitignore: .claude is per-user state except .claude/skills by @mgravell in #3306
• Command coverage ledger and audit skill by @mgravell in #3311
• Update public API docs by @mgravell in https://github.com/StackExchange/StackExchange.Redis/pull/3429

V4 preview. Since 4.0.127-alpha, mostly client-side caching: Clock eviction, the public ClientCache view (GetClientCache()), opt-in / opt-out modes and flags (#3297), group-level cache configuration (#3304), and the None and KeyspaceNotifications modes with Default falling back to keyspace notifications (#3305); plus main merged in up to 2026-10-23 (#3298).

Stability improvements

• Do not abandon a connection attempt before ConnectTimeout has elapsed by @mgravell in #3277
• Read HELLO "server" before trusting "version" as the Redis API version by @mgravell in #3279
• Sentinel soft-fail follow-ups: discovery failure as RedisConnectionException, late sentinel init, clear LastException by @mgravell in #3280
• Sentinel: re-resolve the primary when it is demoted on a healthy connection by @rebaseandpanic in #3281
• Route as a cluster only with a slot map; take HELLO mode/role from the interactive connection only by @mgravell in #3285
• Fail connection-dropped commands with RedisConnectionException, never a raw transport exception or a cancellation by @mgravell in #3287
• Connection groups: a member answering LOADING triggers an immediate re-probe and re-select by @mgravell in #3289
• IBatch: complete commands refused by a poisoned connection; divert a batch's tail on reconnect by @mgravell in #3286
• Give multi-message sub-commands and injected prefix commands a write time by @mgravell in #3293
• Send primary-only commands to the primary when the caller prefers a replica by @AsadIqbal-Dev in #3291

Maintenance

• Tests: stabilise two recurring Windows CI flakes (hash-field expiry clock skew, backlog counter quiescence) by @mgravell in #3288
• Tests: don't race the connect's own reconfigures in AllClusterCommandsRefusedIsQuiet by @mgravell in #3290
• Refresh package pins: 10.0.13 servicing family and tooling by @mgravell in #3294
• xunit.v3 4.0 on Microsoft.Testing.Platform by @mgravell in #3295
• StyleCop.Analyzers 1.3.151-beta, and the tidy-up it asks for by @mgravell in #3296
