Not able to use hiredis with redis-py for server-assisted client-side caching
Version: redis-py - 5.1.0b7, hiredis - 3.0.0
Platform: Python 3.9 in MacBook Apple M3 Pro
Description: Trying server-assisted client-side caching with redis-py version 5.1.0b7, it worked fine without hredis. Tried with hiredis for additional performance, getting the following error once hiredis is installed and ran the script. Does it require any additional change, from this https://redis.io/docs/latest/develop/connect/clients/python/redis-py/ came to know no additional changes is required for most of the cases.

https://github.com/redis/redis-py/pull/3324 was released but its still failing
hiredis 3.1.0
redis 5.2.1
Is there a workaround for this? It still doesn't work.
$ pip list | grep redis
hiredis 3.1.0
redis 5.2.1
>>> import redis
>>> from redis.cache import CacheConfig

Hello everyone!
This was fixed, and you can test it by using hiredis>=3.2.0 and redis-py from the master branch.
Let me know if you have any feedback or questions!
Fix is now available as part of https://github.com/redis/redis-py/releases/tag/v.6.2.0 release
@uglide As an aside, why was the release tag format changed from v6.1.0 to v.6.2.0 (extra dot)? I foresee that breaking systems...

By mistake :( I'll check how this can be fixed...
@akx In which case it makes sense to pull a package from GitHub rather then using a package manager? This is the whole purpose of pip to provide a layer of abstraction from GitHub, so things can be decoupled. So changing naming schema is an issue, but I don't see how this should impact a lot of systems.

Not necessarily the wheel itself, but, say, change logs for a given version, now that they are only tracked in Github releases.
