Breaking changes
This library no longer supports ioredis. It only supports redis (v5 and later) now.
Rationale: Due to the growing divergence between the ioredis and redis libraries, it was causing this library to maintain shims to synthesize the two, which was a source of issues and overhead. Following the recommendations from Redis, we will use redis going forward (we support both a single client and cluster APIs): see https://redis.io/docs/latest/develop/clients/nodejs/migration/
