Hello! This file is just a placeholder, since this is the "unstable" branch of Redis, the place where all the development happens. There is no release notes for this branch, it gets forked into another branch every time there is a partial feature freeze in order to eventually create a new stable release. Usually "unstable" is stable enough for you to use it in development environments however you should never use it in production environments. It is possible to download the latest stable release here: https://download.redis.io/redis-stable.tar.gz More information is available at https://redis.io Happy hacking!
