# Docker Trusted Registry: Release Notes

## Prior Versions

These notes refer to the current and immediately prior releases of Docker Trusted Registry and the commercially supported Docker Engine. For notes on older versions of these, see the [prior release notes archive]({{< relref "prior-release-notes.md" >}}).

## Docker Trusted Registry (DTR)

### DTR 1.2.0
(23 July 2015)

This release adds CentOS support and addresses a few bugs and issues in DTR 1.1.0:

* Fixed an issue where for certain configurations of DTR, proxy configuration settings and variables were not being passed to all DTR containers and thus were not being respected.
* Documentation links in the UI now point to correct docs.
* Generated support info bundles have been scrubbed to remove highly sensitive data.
* Certifies support for CentOS 7.1.

### DTR 1.1.0
(23 June 2015)

This release of DTR (formerly DHE) adds major integration with the AWS and Azure marketplaces, giving customers a smoother installation path. DTR 1.1 also adds finer-grained permissions and improvements and additions to the UI and logging. Bugs in LDAP/AD integration have also been remediated, improving the stability and usability of DTR. See below for specifics.

#### New Features

* New, more granular, [roles for users]({{< relref "configuration.md#authentication" >}}). DTR users can now be assigned different levels of access (admin, r/w, r/o) to the repositories. **Important:** Existing DTR users should make sure to see the note [below](#upgrade-warning) regarding migrating users before upgrading.
* A new storage status indicator for storage space. The dashboard now shows used and available storage space for supported storage drivers.
* A new [diagnostics tool]({{< relref "adminguide.md#client-docker-daemon-diagnostics" >}}) gathers and bundles DTR logs, system information, container information, and other configuration settings for use by Docker support or as a backup.
* Performance and reliability improvements to the S3 storage backend.
* DTR images are now available on the Amazon AWS and Microsoft Azure marketplaces.

#### Fixes

The following notable issues have been remediated:

* Fixed an issue that caused DTR logins to fail if some LDAP servers were unreachable.
* Fixed a resource leak in DTR storage.

### Upgrade Warning

Customers who are currently using DHE 1.0 **must** follow the [upgrading instructions](https://forums.docker.com/t/upgrading-docker-hub-enterprise-to-docker-trusted-registry/1925) in our support Knowledge Base. These instructions will show you how to modify existing authentication data and storage volume settings to move to DTR. Note that automatic upgrading has been disabled for DHE users because of these issues.

## Commercially Supported Docker Engine

### CS Docker Engine 1.6.2-cs6
(23 July 2015)

* Certifies support for CentOS 7.1.

### CS Docker Engine 1.6.2-cs5
(21 May 2015)

For customers running Docker Engine on [supported versions of RedHat Enterprise
Linux](https://www.docker.com/enterprise/support/) with [SELinux
enabled](https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/
6/html/Security-Enhanced_Linux/sect-Security-Enhanced_Linux-Working_with_SELinux
-Enabling_and_Disabling_SELinux.html), the `docker build` and `docker run`
commands will not have DNS host name resolution and bind-mounted volumes may
not be accessible.
As a result, customers with SELinux will be unable to use hostname-based network
access in either `docker build` or `docker run`, nor will they be able to
`docker run` containers
that use `--volume` or `-v` bind-mounts (with an incorrect SELinux label) in
their environment. By installing Docker Engine 1.6.2-cs5, customers can use Docker as intended on RHEL with SELinux enabled.
<commit_msg>RH changed the link to the SELinux docs, updated it to point to a RHEL7 version<commit_after>
