5.0.0b3

Changes

This beta release includes 2 bug fixes for the RESP3 parser.

🐛 Bug Fixes

• Fix protocol version check (#2737)
• Fix COMMAND response callback (#2740)

5.0.0b2

Changes

This release includes only support for RESP3, it should be treated as a beta. Please note response types change for those using RESP3 - meaning there breaking changes. Today this includes support for the following:

• Pub/Sub (#2721)
• Async Pub/Sub (#2721)

The following are not yet implemented:

• Async Pub/Sub with hiredis support, for PUSH responses.

RESP3 support introduces two different ways to enable a RESP3 redis connection, when your redis server supports it.

1. redis_url has been updated to match the uri specification meaning one can now connect by:

import redis
r = redis.Redis.from_url("redis://localhost:6379?protocol=3")
r.ping()

2. One can pass protocol=3 into any existing connection object eg:

from redis.asyncio import  Redis
r = Redis(host="localhost", port=6379, protocol=3)
r.ping()
