For the 16 formal release announcement, see [the Docker 17 blog](https://blog.docker.com/2015/04/docker-release-1-6/). 18 19 20 21 ## Docker Engine 1.6.0 features 22 23 For a complete list of engine patches, fixes, and other improvements, see the 24 [merge PR on GitHub](https://github.com/docker/docker/pull/11635). You'll also 25 find [a changelog in the project 26 repository](https://github.com/docker/docker/blob/master/CHANGELOG.md). 27 28 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). | 38 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 141 142 See the [DHE and CS Docker Engine release notes](docker-hub-enterprise/release-notes.md).
