- Enhanced the metrics exported by cStor Pools to include details of the provisioning errors.
- Fixes an issue where cStor replica snapshots created for the rebuild were not deleted, causing space reclamation to fail.
- Fixes an issue where cStor volume used space was showing a very low value than actually used.
- Fixes an issue where Jiva replicas failed to register with its target if there was an error during initial registration.
- Fixes an issue where NDM would create a partitioned OS device as a block device.
- Fixes an issue where Jiva replica data was not clean up if the PVC and its namespace were deleted prior to scrub job completion.

Release Notes		Enhanced the cStor Data Engine containers to contain troubleshooting utilities.-Enhanced cStor Data Engine to allow interoperability of cStor Replicas across different versions. -Support for using Block Devices for OpenEBS Local PV.
- Support for Dynamic Provisioning of Local PV
- Enhanced the cStor Volumes to support Backup/Restore to S3 compatible storage using the incremental snapshots supported by cStor Volumes.
- Enhanced the cStor Volume Replica to support an anti-affinity feature that works across PVs.

- Enhanced the cStor Volume Provisioning to be customized for varying workload or platform type during the volume provisioning.

- Fixes an issue where NDM pods failed to start on nodes with selinux=on.
- Fixes an issue where cStor Volume with single replicas were shown to be in Degraded, rebuilding state.
- Fixes an issue where user was able to delete a PVC, even if there were clones created from it, resulting in data loss for the cloned volumes.
- Fixes an issue where user was able to delete a PVC, even if there were clones created from it, resulting in data loss for the cloned volumes.
- Fixes an issue where cStor Volumes failed to provision if the /var/openebs/ directory was not editable by cStor pods like in the case of SuSE Platforms.
- Fixes an issue where Jiva Volume - Target can mark a replica as offline if the replica takes longer than 30s to complete the sync/unmap IO.
- Fixes an issue with Jiva volume - space reclaim thread, that was erroring out with an exception if the replica is disconnected from the target.

0.8.2		Release NotesEnhanced the metrics exported by cStor Pools to include details of the provisioning errors.-Enhanced the cStor Data Engine containers to contain troubleshooting utilities.-Enhanced cStor Data Engine to allow interoperability of cStor Replicas across different versions.
- Fixed an issue causing cStor Volume Replica CRs to be stuck, when the OpenEBS
namespace was being deleted.
- Fixed an issue where a newly added cStor Volume Replica may not be successfully
registered with the cStor target, if the cStor tries to connect to Replica before the replica
is completely initialised.
- Fixed an issue with Jiva Volumes where target can mark the Replica as Timed out on IO,
even when the Replica might actually be processing the Sync IO.
- Fixed an issue with Jiva Volumes that would not allow for Replicas to re-connect with the
Target, if the initial Registration failed to successfully process the hand-shake request.
- Fixed an issue with Jiva Volumes that would cause Target to restart when a send
diagnostic command was received from the client
- Fixed an issue causing PVC to be stuck in pending state, when there were more than
one PVCs associated with an Application Pod
- Toleration policy support for cStorStoragePool.
