    29  | Feature                      | Description                                                                                                                                                                                                                                                                                                                                                                                                                                                        |
    30  |------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
    31  | Container and Image Labels   | Labels allow you to attach user-defined metadata to containers and images that can be used by your tools. For additional information on using labels, see [Apply custom metadata](https://docs.docker.com/userguide/labels-custom-metadata/#add-labels-to-images-the-label-instruction) in the documentation.                                                                                                                                                    |
    32  | Windows Client preview       | The Windows Client can be used just like the Mac OS X client is today with a remote host. Our testing infrastructure was scaled out to accommodate Windows Client testing on every PR to the Engine. See the Azure blog for [details on using this new client](http://azure.microsoft.com/blog/2015/04/16/docker-client-for-windows-is-now-available).                                                                                                           |
    33  | Logging drivers              | The new logging driver follows the exec driver and storage driver concepts already available in Engine today. There is a new option `--log-driver` to `docker run` command. See the `run` reference for a [description on how to use this option](https://docs.docker.com/reference/run/#logging-drivers-log-driver).                                                                                                                                            |
    34  | Image digests                | When you pull, build, or run images, you specify them in the form `namespace/repository:tag`, or even just `repository`. In this release, you are now able to pull, run, build and refer to images by a new content addressable identifier called a “digest” with the syntax `namespace/repo@digest`. See the the command line reference for [examples of using the digest](https://docs.docker.com/reference/commandline/cli/#listing-image-digests).           |
    35  | Custom cgroups               | Containers are made from a combination of namespaces, capabilities, and cgroups. Docker already supports custom namespaces and capabilities. Additionally, in this release we’ve added support for custom cgroups. Using the `--cgroup-parent` flag, you can pass a specific `cgroup` to run a container in. See [the command line reference for more information](https://docs.docker.com/reference/commandline/cli/#create).                                   |
    36  | Ulimits                      | You can now specify the default `ulimit` settings for all containers when configuring the daemon. For example:`docker -d --default-ulimit nproc=1024:2048` See [Default Ulimits](https://docs.docker.com/reference/commandline/cli/#default-ulimits) in this documentation.                                                                                                                                                                                   |
    37  | Commit and import Dockerfile | You can now make changes to images on the fly without having to re-build the entire image. The feature `commit --change` and `import --change` allows you to apply standard changes to a new image. These are expressed in the Dockerfile syntax and used to modify the image. For details on how to use these, see the [commit](https://docs.docker.com/reference/commandline/cli/#commit) and [import](https://docs.docker.com/reference/commandline/cli/#import). |

    39  ### Known issues in Engine
    40  
    41  This section lists significant known issues present in Docker as of release date.
    42  For an exhaustive list of issues, see [the issues list on the project
    43  repository](https://github.com/docker/docker/issues/).
    44  
    45  * *Unexpected File Permissions in Containers*
    46  An idiosyncrasy in AUFS prevented permissions from propagating predictably
    47  between upper and lower layers. This caused issues with accessing private
    48  keys, database instances, etc.  This issue was closed in this release:
    49  [Github Issue 783](https://github.com/docker/docker/issues/783).
    50  
    51  
    52  * *Docker Hub incompatible with Safari 8*
    53  Docker Hub had multiple issues displaying on Safari 8, the default browser for
    54  OS X 10.10 (Yosemite).  Most notably, changes in the way Safari handled cookies
    55  means that the user was repeatedly logged out.
    56  Recently, Safari fixed the bug that was causing all the issues. If you upgrade
    57  to Safari 8.0.5 which was just released last week and see if that fixes your
    58  issues. You might have to flush your cookies if it doesn't work right away.
    59  For more information, see the [Docker forum
    60  post](https://forums.docker.com/t/new-safari-in-yosemite-issue/300).
    61  
    62  ## Docker Registry 2.0 features
    63  
    64  This release includes Registry 2.0. The Docker Registry is a central server for
    65  pushing and pulling images. In this release, it was completely rewritten in Go
    66  around a new set of distribution APIs
    67  
    68  - **Webhook notifications**: You can now configure the Registry to send Webhooks
    69  when images are pushed. Spin off a CI build, send a notification to IRC –
    70  whatever you want! Included in the documentation is a detailed [notification
    71  specification](https://docs.docker.com/registry/notifications/).
    72  
    73  - **Native TLS support**: This release makes it easier to secure a registry with
    74  TLS.  This documentation includes [expanded examples of secure
    75  deployments](https://docs.docker.com/registry/deploying/).
    76  
    77  - **New Distribution APIs**: This release includes an expanded set of new
    78  distribution APIs. You can read the [detailed specification
    79  here](https://docs.docker.com/registry/spec/api/).
    80  
    81  
    82  ## Docker Compose 1.2
    83  
    84  For a complete list of compose patches, fixes, and other improvements, see the
    85  [changelog in the project
    86  repository](https://github.com/docker/compose/blob/master/CHANGES.md). The
    87  project also makes a [set of release
    88  notes](https://github.com/docker/compose/releases/tag/1.2.0) on the project.
    89  
    90  - **extends**:  You can use `extends` to share configuration between services
    91  with the keyword “extends”. With extends, you can refer to a service defined
    92  elsewhere and include its configuration in a locally-defined service, while also
    93  adding or overriding configuration as necessary. The documentation describes
    94  [how to use extends in your
    95  configuration](https://docs.docker.com/compose/extends/#extending-services-in-
    96  compose).
    97  
    98  - **Relative directory handling may cause breaking change**: Compose now treats
    99  directories passed to build, filenames passed to `env_file` and volume host
   100  paths passed to volumes as relative to the configuration file's directory.
   101  Previously, they were treated as relative to the directory where you were
   102  running `docker-compose`. In the majority of cases, the location of the
   103  configuration file and where you ran `docker-compose` were the same directory.
   104  Now, you can use the `-f|--file` argument to specify a configuration file in
   105  another directory. 
   106  
   107  
   108  ## Docker Swarm 0.2
   109  
   110  You'll find the [release for download on
   111  GitHub](https://github.com/docker/swarm/releases/tag/v0.2.0) and [the
   112  documentation here](https://docs.docker.com/swarm/).  This release includes the
   113  following features:
   114  
   115  - **Spread strategy**: A new strategy for scheduling containers on your cluster
   116  which evenly spreads them over available nodes.
   117  - **More Docker commands supported**: More progress has been made towards
   118  supporting the complete Docker API, such as pulling and inspecting images.
   119  - **Clustering drivers**: There are not any third-party drivers yet, but the
   120  first steps have been made towards making a pluggable driver interface that will
   121  make it possible to use Swarm with clustering systems such as Mesos.
   122  
   123  
   124  ## Docker Machine 0.2 Pre-release
   125  
   126  You'll find the [release for download on
   127  GitHub](https://github.com/docker/machine/releases) and [the documentation
   128  here](https://docs.docker.com/machine/).  For a complete list of machine changes
   129  see [the changelog in the project
   130  repository](https://github.com/docker/machine/blob/master/CHANGES.md#020-2015-03
   131  -22).
   132  
   133  - **Cleaner driver interface**: It is now much easier to write drivers for providers.
   134  - **More reliable and consistent provisioning**: Provisioning servers is now
   135  handled centrally by Machine instead of letting each driver individually do it.
   136  - **Regenerate TLS certificates**: A new command has been added to regenerate a
   137  host’s TLS certificates for good security practice and for if a host’s IP
   138  address changes. 
   139  
   140  ## Docker Hub Enterprise & Commercially Supported Docker Engine
