What is the end of life date for Redis versions.
Is there any official document announcing the end of life date for Redis versions.
If you are referring to Redis Enterprise Software:
The official page is here: https://docs.redis.com/latest/rs/administering/product-lifecycle/
The official page for modules is here: https://docs.redis.com/latest/modules/modules-lifecycle/
For Open Source Redis, the official details are here https://redis.io/about/releases/ :
As a rule, older versions are not supported as we try very hard to make the Redis API mostly backward compatible.
Upgrading to newer versions is the recommended approach and is usually trivial.
The latest stable release is always fully supported and maintained.
Two additional versions receive maintenance only, meaning that only fixes for critical bugs and major security issues are committed and released as patches:
The previous minor version of the latest stable release. The previous stable major release. For example, consider the following hypothetical versions: 1.2, 2.0, 2.2, 3.0, 3.2.
When version 2.2 is the latest stable release, both 2.0 and 1.2 are maintained.
Once version 3.0.0 replaces 2.2 as the latest stable, versions 2.0 and 2.2 are maintained, whereas version 1.x reaches its end of life.
This process repeats with version 3.2.0, after which only versions 2.2 and 3.0 are maintained.
The above are guidelines rather than rules set in stone and will not replace common sense.
