+# Release notes for Gluster 3.11.1
+This is a bugfix release. The release notes for [3.11.0](3.11.0.md), contains a
+listing of all the new features that were added and bugs fixed, in the
+GlusterFS 3.11 stable release.
+## Major changes, features and limitations addressed in this release
+### Improved disperse performance
+Fix for bug [#1456259](https://bugzilla.redhat.com/1456259) changes the way
+messages are read and processed from the socket layers on the Gluster client.
+This has shown performance improvements on disperse volumes, and is applicable
+to other volume types as well, where there maybe multiple applications or users
+accessing the same mount point.
+### Group settings for enabling negative lookup caching provided
+Ability to serve negative lookups from cache was added in 3.11.0 and with
+this release, a group volume set option is added for ease in enabling this
+See [group-nl-cache](https://github.com/gluster/glusterfs/blob/release-3.11/extras/group-nl-cache) for more details.
+### Gluster fuse now implements "-oauto_unmount" feature.
+libfuse has an auto_unmount option which, if enabled, ensures that the file
+system is unmounted at FUSE server termination by running a separate monitor
+process that performs the unmount when that occurs. This release implements that
+option and behavior for glusterfs.
+Note that "auto unmount" (robust or not) is a leaky abstraction, as the kernel
+cannot guarantee that at the path where the FUSE fs is mounted is actually the
+toplevel mount at the time of the umount(2) call, for multiple reasons,
+among others, see:
+- fuse-devel: ["fuse: feasible to distinguish between umount and abort?"](http://fuse.996288.n3.nabble.com/fuse-feasible-to-distinguish-between-umount-and-abort-tt14358.html)
+## 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.
+ - Status of this bug can be tracked here, #1465123
