+## Known Issues
+
+- Commit b33f3c9, which introduces changes to improve IPv6 support in GlusterFS has been reverted as it exposed problems in network encryption, which could cause a GlusterFS cluster to fail operating correctly when management network encryption is used.
+- Network encryption has an issue which could sometimes prevent reconnections from correctly happening.
