#Hollo now can work without #Redis. It uses Redis as a cache and queue backend if the REDIS_URL environment variable is provided, but if not given, it caches in memory and works without a queue. This is an option to consider if you have a few following/followers.

#Hollo now uses PostgreSQL for caching and message queue by default (unless the REDIS_URL environment variable is present)! It's quite performant and scalable when it's compared to Redis, so we've decided to make it the default configuration.
