Note: UCP 1.1.3 supports Docker Engine 1.12 but does not use the built-in

orchestration capabilities provided by the Docker Engine on swarm mode. When

installing this UCP version on a Docker Engine 1.12 host, UCP creates a cluster

using Docker Swarm 1.2.5.

**Security Update**

Fixes a security issue by which a malicious user with limited privileges can

perform unauthorized actions on the cluster via the API.

**Features**

* Core

* Upgraded Docker Swarm to 1.2.5

* Non-admin users no longer have the ability to edit or delete UCP/DTR volumes

and networks.

* The Pull Image, Delete Image, Create Volume, Delete Volume, Create Network

and Delete Network operations are now inaccessible to users with View Only

default permissions or lower.

**Bug Fixes**

* Improved system performance when large numbers of overlay networks are deployed

on the cluster.

* Fixed an issue which affected container rescheduling on clusters with overlay

networks.

* Fixed an issue which affected synchronizing organization owners (admins) in

LDAP when migrating from DTR 1.4.3 to 2.0.x

* Fixed an issue where UCP/DTR integration config was not loaded when UCP

controller was restarted.

* Fixed an issue in the GUI where the sidebar does not display when first

logging into UCP.

* Fixed an issue where volumes created through the UCP GUI did not correctly

populate the labels field.

**Known Issues**

* This version of UCP cannot be installed on Engine 1.12 host with swarm mode

enabled, and is not compatible with swarm-mode based APIs, e.g. `docker service`.
