# RedisBloom 1.0 release notes












## Requirements

RedisBloom v1.0.3 requires:

- Minimum Redis compatibility version (database): 4.0
- Minimum Redis Enterprise Software version (cluster): 5.0

## v1.0.3 (December 2017)

This contains a single fix, issue #[19](http://github.com/RedisBloom/RedisBloom/issues/19).

From this version onwards, `EXISTS`/`MEXISTS` returns 0 if the (Redis) key does not exist in the database.  Earlier versions returned an error.

## v1.0.2 (November 2017)

This fixes a build issue (fixed s3 config in circle yaml).

## v1.0.0 (September 2017)

This is the first GA release of ReBloom.
