parent 406a365f
Hello! This file is just a placeholder, since this is the "unstable" branch Redis Community Edition 8.0 release notes
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 8.0-M01 (v7.9.224) Released Thu 12 Sep 2024 10:00:00 IST
a new stable release. ===========================================================
Usually "unstable" is stable enough for you to use it in development environments This is the first Milestone of Redis Community Edition 8.0.
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 Milestones are non-feature-complete pre-releases. Pre-releases are not suitable for production use.
Once we reach feature-completeness we will release RC1.
More information is available at https://redis.io ### Headlines:
Redis 8.0 introduces new data structures: JSON, time series, and 5 probabilistic data structures (previously available as separate Redis modules) and incorporates Redis scalable query engine (including vector search).
8.0-M01 is available as a Docker image and can be downloaded from [Docker Hub](https://hub.docker.com/_/redis). Additional distributions will be introduced in upcoming pre-releases.
### Supported upgrade paths (by replication or persistence) to 8.0-M01
- From previous Redis versions, without modules
The following upgrade paths (by replication or persistence) to 8.0-M01 are not yet tested and will be introduced in upcoming pre-releases:
- From previous Redis versions with modules (RediSearch, RedisJSON, RedisTimeSeries, RedisBloom)
- From Redis Stack 7.2 or 7.4
### New Features in binary distributions
- 7 new data structures: JSON, Time series, Bloom filter, Cuckoo filter, Count-min sketch, Top-k, t-digest
- Redis scalable query engine (including vector search)

- #13516 Optimize `LRANGE` and other commands that perform several writes to client buffers per call
- #13431 Avoid `used_memory` contention when updating from multiple threads
### Other general improvements
- #13495 Reply `-LOADING` on replica while flushing the db
