**No Major changes**

## Major issues
1. Expanding a gluster volume that is sharded may cause file corruption
    - Sharded volumes are typically used for VM images, if such volumes are
  expanded or possibly contracted (i.e add/remove bricks and rebalance) there
  are reports of VM images getting corrupted.
    - The last known cause for corruption (Bug #1515434) is still under review.
    - Status of this bug can be tracked here, [#1515434](https://bugzilla.redhat.com/1515434)
