- Added a `swarm-exec` to execute a docker command across all of the swarm nodes. See [Executing Docker commands in all swarm nodes](deploy.md#execute-docker-commands-in-all-swarm-nodes) for more details.

### 1.12.3-beta10

Release date: 11/08/2016

**New**

- Docker Engine upgraded to Docker 1.12.3
- Fixed the shell container that runs on the managers, to remove a ssh host key that was accidentally added to the image.
This could have led to a potential man in the middle (MITM) attack. The ssh host key is now generated on host startup, so that each host has its own key.
- The SSH ELB for connecting to the managers using SSH has been removed because it is no longer possible to SSH into the managers without getting a security warning
- Multiple managers can be deployed
- All container logs can be found in the `xxxxlog` storage account
- You can connect to each manager using SSH by following our deploy [guide](deploy.md)

### 1.12.2-beta9

Release date: 10/17/2016

**New**

- Docker Engine upgraded to Docker 1.12.2
- Manager behind its own LB
- Added sudo support to the shell container on manager nodes

### 1.12.1-beta5

Release date: 8/19/2016

**New**

 * Docker Engine upgraded to 1.12.1

### Errata

 * To assist with debugging, the Docker Engine API is available internally in the Azure VPC on TCP port 2375. These ports cannot be accessed from outside the cluster, but could be used from within the cluster to obtain privileged access on other cluster nodes. In future releases, direct remote access to the Docker API will not be available.

### 1.12.0-beta4

Release date: 8/9/2016

**New**

 * First release

### Errata

 * To assist with debugging, the Docker Engine API is available internally in the Azure VPC on TCP port 2375. These ports cannot be accessed from outside the cluster, but could be used from within the cluster to obtain privileged access on other cluster nodes. In future releases, direct remote access to the Docker API will not be available.
