# Release notes for Gluster 3.10.1
This is a bugfix release. The release notes for [3.10.0](3.10.0.md),
contains a listing of all the new features that were added and
bugs in the GlusterFS 3.10 stable release.
## Major changes, features and limitations addressed in this release
1. auth-allow setting was broken with 3.10 release and is now fixed (#1429117)
## 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.
- If you are using sharded volumes, DO NOT rebalance them till this is
fixed
