| Feature | Description |
|
||
|------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
||
| 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. |
|
||
| 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). |
|
||
| 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). |
|
||
| 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). |
|
||
| 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). |
|
||
| Ulimits | You can now specify the default `ulimit` settings for all containers when configuring the daemon. For example:`docker daemon --default-ulimit nproc=1024:2048` See [Default Ulimits](https://docs.docker.com/reference/commandline/cli/#default-ulimits) in this documentation. |
|
||
| 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). |

### Known issues in Engine
|
||
|
||
This section lists significant known issues present in Docker as of release date.
|
||
For an exhaustive list of issues, see [the issues list on the project
|
||
repository](https://github.com/docker/docker/issues/).
|
||
|
||
* *Unexpected File Permissions in Containers*
|
||
An idiosyncrasy in AUFS prevented permissions from propagating predictably
|
||
between upper and lower layers. This caused issues with accessing private
|
||
keys, database instances, etc. This issue was closed in this release:
|
||
[GitHub Issue 783](https://github.com/docker/docker/issues/783).
|
||
|
||
|
||
* *Docker Hub incompatible with Safari 8*
|
||
Docker Hub had multiple issues displaying on Safari 8, the default browser for
|
||
OS X 10.10 (Yosemite). Most notably, changes in the way Safari handled cookies
|
||
means that the user was repeatedly logged out.
|
||
Recently, Safari fixed the bug that was causing all the issues. If you upgrade
|
||
to Safari 8.0.5 which was just released last week and see if that fixes your
|
||
issues. You might have to flush your cookies if it doesn't work right away.
|
||
For more information, see the [Docker forum
|
||
post](https://forums.docker.com/t/new-safari-in-yosemite-issue/300).

|
||
## Docker Registry 2.0 features
|
||
|
||
This release includes Registry 2.0. The Docker Registry is a central server for
|
||
pushing and pulling images. In this release, it was completely rewritten in Go
|
||
around a new set of distribution APIs
|
||
|
||
- **Webhook notifications**: You can now configure the Registry to send Webhooks
|
||
when images are pushed. Spin off a CI build, send a notification to IRC –
|
||
whatever you want! Included in the documentation is a detailed [notification
|
||
specification](https://docs.docker.com/registry/notifications/).
|
||
|
||
- **Native TLS support**: This release makes it easier to secure a registry with
|
||
TLS. This documentation includes [expanded examples of secure
|
||
deployments](https://docs.docker.com/registry/deploying/).
|
||
|
||
- **New Distribution APIs**: This release includes an expanded set of new
|
||
distribution APIs. You can read the [detailed specification
|
||
here](https://docs.docker.com/registry/spec/api/).
|
||
|
||
|
||
## Docker Compose 1.2
|
||
|
||
For a complete list of compose patches, fixes, and other improvements, see the
|
||
[changelog in the project
|
||
repository](https://github.com/docker/compose/blob/master/CHANGES.md). The
|
||
project also makes a [set of release
|
||
notes](https://github.com/docker/compose/releases/tag/1.2.0) on the project.
|
||
|
||
- **extends**: You can use `extends` to share configuration between services
|
||
with the keyword “extends”. With extends, you can refer to a service defined
|
||
elsewhere and include its configuration in a locally-defined service, while also
|
||
adding or overriding configuration as necessary. The documentation describes
|
||
[how to use extends in your
|
||
configuration](https://docs.docker.com/compose/extends/#extending-services-in-
|
||
compose).
|
||
|
||
- **Relative directory handling may cause breaking change**: Compose now treats
|
||
directories passed to build, filenames passed to `env_file` and volume host
|
||
paths passed to volumes as relative to the configuration file's directory.
|
||
Previously, they were treated as relative to the directory where you were
|
||
running `docker-compose`. In the majority of cases, the location of the
|
||
configuration file and where you ran `docker-compose` were the same directory.
|
||
Now, you can use the `-f|--file` argument to specify a configuration file in
|
||
another directory.
|
||
|
||
|
||
## Docker Swarm 0.2
|
||
|
||
You'll find the [release for download on
|
||
GitHub](https://github.com/docker/swarm/releases/tag/v0.2.0) and [the
|
||
documentation here](https://docs.docker.com/swarm/). This release includes the
|
||
following features:
|
||
|
||
- **Spread strategy**: A new strategy for scheduling containers on your cluster
|
||
which evenly spreads them over available nodes.
|
||
- **More Docker commands supported**: More progress has been made towards
|
||
supporting the complete Docker API, such as pulling and inspecting images.
|
||
- **Clustering drivers**: There are not any third-party drivers yet, but the
|
||
first steps have been made towards making a pluggable driver interface that will
|
||
make it possible to use Swarm with clustering systems such as Mesos.
|
||
|
||
|
||
## Docker Machine 0.2 Pre-release
|
||
|
||
You'll find the [release for download on
|
||
GitHub](https://github.com/docker/machine/releases) and [the documentation
|
||
here](https://docs.docker.com/machine/). For a complete list of machine changes
|
||
see [the changelog in the project
|
||
repository](https://github.com/docker/machine/blob/master/CHANGES.md#020-2015-03
|
||
-22).
|
||
|
||
- **Cleaner driver interface**: It is now much easier to write drivers for providers.
|
||
- **More reliable and consistent provisioning**: Provisioning servers is now
|
||
handled centrally by Machine instead of letting each driver individually do it.
|
||
- **Regenerate TLS certificates**: A new command has been added to regenerate a
|
||
host’s TLS certificates for good security practice and for if a host’s IP
|
||
address changes.
|
||
|
||
