🚀 Highlights

FIPS-Compatible Script Helper

Script now supports a FIPS-safe execution mode that avoids client-side SHA-1 computation, which is blocked in strict FIPS environments. A new NewScriptServerSHA constructor uses SCRIPT LOAD to obtain and cache the digest from the server, then runs commands via EVALSHA/EVALSHA_RO. Falls back to EVAL/EVALRO if loading fails, and transparently retries once on NOSCRIPT. The default behavior is unchanged for existing users.

(#3700) by @chaitanyabodlapati

FT.AGGREGATE Step-Based Pipeline Builder

Added a new step-based FT.AGGREGATE pipeline API via FTAggregateOptions.Steps, allowing LOAD, APPLY, GROUPBY, and SORTBY (with per-step MAX) to be repeated and interleaved in arbitrary order — matching Redis's native multi-stage aggregation semantics. The legacy Load/Apply/GroupBy/SortBy/SortByMax fields are now deprecated.

(#3782) by @ndyakov

Raw RESP Protocol Access

Added DoRaw and DoRawWriteTo methods for executing arbitrary commands and reading the raw RESP response. Useful for proxying, custom protocol inspection, and working with commands not yet wrapped by go-redis.

(#3713) by @ofekshenawa

Configurable Dial Retry Backoff

Added DialerRetryBackoff option (plumbed through Options, ClusterOptions, RingOptions, FailoverOptions) to let callers customize the delay between failed dial attempts. Helpers DialRetryBackoffConstant and DialRetryBackoffExponential (with jitter and cap) are provided out of the box. Dial timeout is now also applied per attempt rather than across all retries.

(#3706, #3705) by @mwhooker

3.4.1 (April 2026)

viaRedisInsight

This is the General Availability (GA) release of Redis Insight 3.4.1, which includes new features, enhancements and bug fixes.

Headlines

New dedicated Search workspace with full index lifecycle support: create indexes from sample data or existing user data, query indexed data with an assisted editor, and save queries to a Query Library for reuse.
Enhancements for Azure integration, including Entra ID Docker support, Access Key authentication, and a manual connection form.

Azure Entra ID authentication support for Docker deployments. To get started, follow the Azure Docker setup guide.
Added a manual connection form for Azure Redis databases, allowing users to configure or override autodiscovery connection details.
Added Access Key authentication support for Azure Redis databases as an alternative to Entra ID.

Changes

Unified command response types across RESP2 and RESP3 protocols

In this release, the command response types across RESP2 and RESP3 protocols are unified, ensuring that the same command returns the same Python type and structure regardless of which protocol version is in use — eliminating the need for protocol-specific branching in application code (#4025). Approximately 84 commands are affected across core Redis, Search, JSON, TimeSeries, and Probabilistic modules. Additionally, the default protocol has been changed from RESP2 to RESP3 for all Redis clients and connections, enabling richer native types (maps, sets, doubles, booleans) and improved performance out of the box (#4031). These changes are breaking relative to redis-py 7.x and earlier, so users upgrading should carefully review the migration guide. For a complete list of affected commands and updated response formats, see docs/resp_unification.rst and the detailed migration guide at specs/resp2_resp3_migration_guide.md. Users who need to retain the previous default protocol configuration can explicitly set protocol=2 when creating their client or connection.

🚀 New Features

Add random load balancing strategy which allows for use of the primary (#4027)

RESP2 and RESP3 response unification (#4025)
Changing the default RESP protocol configurations for Redis clients and connections to 3 (#4031)

🧰 Maintenance

🔭 Observability (OTEL + Diagnostics)

Node Redis now ships with first-class observability via OpenTelemetry metrics and Node.js diagnostics_channel. Initialize OpenTelemetry before creating clients (OpenTelemetry.init({ metrics: { enabled: true } })) and you can plug Redis client telemetry into your existing OTel SDK/exporter pipeline.

This enables visibility into command latency, connection lifecycle, resiliency/errors, Pub/Sub traffic, streaming behavior, and client-side caching activity. On top of metrics, diagnostics channels provide a more abstract, higher-level way to track runtime behavior through low-overhead event streams (commands, batches, connection events, maintenance notifications, pub/sub, cache, and pool wait timing), so APM tools or custom subscribers can observe the system without changing application code.

v8.0.0b1 ↗

viaredis-py

Changes

Async Cluster PubSub & Keyspace Notifications

This release introduces full asyncio Cluster PubSub support, bringing shard-channel capabilities (SSUBSCRIBE, SUNSUBSCRIBE, SPUBLISH) to the async RedisCluster client. The new ClusterPubSub class in redis.asyncio.cluster automatically routes shard-channel subscriptions to the correct cluster node based on key-slot hashing, manages per-node PubSub connections, and supports round-robin message retrieval across nodes. Users can create a cluster pubsub instance via RedisCluster.pubsub() and use ssubscribe(), sunsubscribe(), and get_sharded_message() just as they would with the sync cluster client.

Alongside this, Redis Keyspace Notifications are now supported for both standalone and cluster deployments, in both sync and async modes. New classes—KeyspaceNotifications, ClusterKeyspaceNotifications, AsyncKeyspaceNotifications, and AsyncClusterKeyspaceNotifications—provide a high-level API for subscribing to keyspace and keyevent channels. In cluster mode, notifications are automatically subscribed across all primary nodes (since each node only emits notifications for keys it owns), with built-in topology-change handling. Convenience methods like subscribe_keyspace(), subscribe_keyevent(), and channel classes (KeyspaceChannel, KeyeventChannel) simplify common subscription patterns. Both sync run_in_thread() and async listen() workflows are supported.

Type Hints Improvements (breaking changes)

The @overload pattern has been applied systematically across core commands (core.py), VectorSet commands, and module commands (Search, JSON, TimeSeries, Bloom filters) to provide distinct return types for sync and async clients. Previously, methods returned a combined ResponseT (i.e., Union[Awaitable[Any], Any]), which caused static analysis tools like mypy and Pyright to flag false positives. Now, sync clients see concrete return types (e.g., int, bool, list[str]) while async clients see Awaitable[...] wrappers. This is a breaking change for type-checking only—runtime behavior is unchanged, but code relying on the old union return types in type annotations may need updates. Two new protocol types, SyncClientProtocol and AsyncClientProtocol, are used in overload signatures to enable this distinction.
