Version 2.2.1 is a bugfix-only release of the opensearch operator. It brings with it fixes for two important bugs:
- After version upgrades or rolling restarts the cluster could become stuck in yellow state (#400)
- If more than one master pod failed at the same time the cluster could get into an unrecoverable state due to loss of quorum (#289)
Please note that the fix for cluster recovery (#289) is experimental. Should you encounter problems with it please open an issue on github to let us know. You can also disable the recovery mode, please see the userguide on cluster recovery on how to do that.
