Changes

🚀 Highlights

Async Cluster PubSub

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.

Keyspace and subkey notifications

Redis Keyspace Notifications are now supported for standalone and cluster deployments in both sync and async modes. New classes — KeyspaceNotifications, ClusterKeyspaceNotifications, AsyncKeyspaceNotifications, and AsyncClusterKeyspaceNotifications — provide a high-level API for keyspace/keyevent subscriptions and subkey notification families: subkeyspace, subkeyevent, subkeyspaceitem, and subkeyspaceevent. Convenience methods like subscribe_keyspace(), subscribe_keyevent(), subscribe_subkeyspace(), subscribe_subkeyevent(), subscribe_subkeyspaceitem(), and subscribe_subkeyspaceevent() simplify common patterns, with channel classes for both key and subkey channels.

In cluster mode, subscriptions are managed across primary nodes because each node emits notifications only for keys it owns, with built-in topology-change handling. Sync run_in_thread() and async listen() workflows are supported.

Redis Array commands(https://redis.io/docs/latest/develop/data-types/arrays/)

redis-py now supports Redis Arrays, a preview Redis data type for sparse, index-addressable sequences of strings. New AR* command helpers cover indexed reads/writes, range scans, deletion, cursor-based insertion, ring-buffer writes, metadata, text search, and aggregation, including ARGET, ARSET, ARMGET, ARMSET, ARSCAN, ARGREP, ARRING, and AROP.

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.

RESP3 by default with opt-in unified responses

redis-py 8.0.0 now uses RESP3 on the wire by default while preserving legacy RESP2-compatible Python response shapes for existing applications (#4052). Protocol-independent unified response shapes are available by setting legacy_responses=False, so affected commands return the same Python structure with RESP2 or RESP3.

Use protocol=2 to force RESP2 on the wire, protocol=3 to opt into native RESP3 response shapes, or legacy_responses=False to migrate to unified responses. See https://github.com/redis/redis-py/blob/HEAD/docs/unified_responses.rst and https://github.com/redis/redis-py/blob/HEAD/specs/unified_responses_migration_guide.md for the affected commands and migration details.

Connection and retry defaults

Default connection settings were updated: socket_timeout and socket_connect_timeout now default to 5 seconds, TCP keepalive is enabled by default, socket reads use a 32 KB buffer, connection pools default to max_connections=100, and retry defaults now use 10 attempts with exponential jitter backoff.

Note: socket_timeout can affect blocking commands such as BLPOP/BRPOP; if a command blocks longer than the client socket timeout, it may raise TimeoutError before the command timeout elapses (#2807).
