5.0.0

What's new?

Triggers and Functions support

Triggers and Functions allow you to execute server-side functions triggered when key values are modified or created in Redis, a stream entry arrival, or explicitly calling them. Simply put, you can replace Lua scripts with easy-to-develop JavaScript or TypeScript code. Move your business logic closer to the data to ensure a lower latency, and forget about updating dependent key values manually in your code.

Python 3.7 End-of-Life

Python 3.7 has reached its end-of-life (EOL) as of June 2023. This means that starting from this date, Python 3.7 will no longer receive any updates, including security patches, bug fixes, or improvements. If you continue to use Python 3.7 post-EOL, you may expose your projects and systems to potential security vulnerabilities. We ended its support in this version and strongly recommend migrating to Python 3.10.

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()
