The CHANGELOG.md file for this module should be updated to document this dependency downgrade from Jedis 6.2.0 to 4.4.8. According to the PR guidelines and best practices, dependency changes should be documented in the CHANGELOG.md under the "Other Changes" section with "Dependency Updates" subsection. The current unreleased version (1.0.0-beta.5) section should include:

#### Dependency Updates

- Downgraded `jedis` from `6.2.0` to version `4.4.8`.

This is particularly important as it's a downgrade (not an upgrade), likely due to licensing concerns with the Elastic-2.0 license in Jedis 6.2.0.
