The CS Engine is functionally equivalent to the corresponding Docker Engine that it references. However, a commercially supported release also includes back-ported fixes (security-related and priority defects) from the open source. It incorporates defect fixes that you can use in environments where new features cannot be adopted as quickly for consistency and compatibility reasons. ## Prior versions These notes refer to the current and immediately prior releases of the CS Engine. For notes on older versions, see the [CS Engine prior release notes archive](prior-release-notes.md). ## CS Engine 1.12.6-cs10 (6 Mar 2017) * Fix concurrency issue in libnetwork ## CS Engine 1.12.6-cs9 (28 Feb 2017) * Fixes an issue causing containerd to deadlock [#336](https://github.com/docker/containerd/pull/336) * Fixes an issue where encrypted overlay networks stop working [#30727](https://github.com/docker/docker/issues/30727) ## CS Engine 1.12.6-cs8 (8 Feb 2017) This release addresses the following issues: * Addresses performance issues introduced by external KV-Store access with the `docker network ls` endpoint with large amounts of overlay networks and containers attached to those networks * Addresses an inconsistent mac -> vtep binding issue when using overlay networks * Adds a new repository for RHEL 7.2 users, to deal with issues users have encountered when installing the docker-engine-selinux package on systems pinned to 7.2 packages that are older than those available in the normal 7.2 install. This change relates to packaging changes for [1.12.6-cs7](#cs-engine-1126-cs7). Users experiencing issues installing the selinux package should switch to this repository. See [install instructions](/cs-engine/install.md) for more details.
