You'll also 44 find [a changelog in the project 45 repository](https://github.com/docker/docker/blob/master/CHANGELOG.md). 46 47 48 | Feature | Description | 49 |------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| 50 | 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. | 51 | 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). | 52 | 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). | 53 | 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). | 54 | 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). | 55 | 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. | 56 | 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). | 57 58 ### Known issues in Engine 59 60 This section lists significant known issues present in Docker as of release date. 61 For an exhaustive list of issues, see [the issues list on the project 62 repository](https://github.com/docker/docker/issues/). 63 64 * *Unexpected File Permissions in Containers* 65 An idiosyncrasy in AUFS prevented permissions from propagating predictably 66 between upper and lower layers. This caused issues with accessing private 67 keys, database instances, etc. This issue was closed in this release: 68 [GitHub Issue 783](https://github.com/docker/docker/issues/783). 69 70 71 * *Docker Hub incompatible with Safari 8* 72 Docker Hub had multiple issues displaying on Safari 8, the default browser for 73 OS X 10.10 (Yosemite). Most notably, changes in the way Safari handled cookies 74 means that the user was repeatedly logged out. 75 Recently, Safari fixed the bug that was causing all the issues. If you upgrade 76 to Safari 8.0.5 which was just released last week and see if that fixes your 77 issues. You might have to flush your cookies if it doesn't work right away. 78 For more information, see the [Docker forum 79 post](https://forums.docker.com/t/new-safari-in-yosemite-issue/300). 80 81 ## Docker Registry 2.0 features 82 83 This release includes Registry 2.0. The Docker Registry is a central server for 84 pushing and pulling images. In this release, it was completely rewritten in Go 85 around a new set of distribution APIs 86 87 - **Webhook notifications**: You can now configure the Registry to send Webhooks 88 when images are pushed. Spin off a CI build, send a notification to IRC – 89 whatever you want! Included in the documentation is a detailed [notification 90 specification](https://docs.docker.com/registry/notifications/). 91 92 - **Native TLS support**: This release makes it easier to secure a registry with 93 TLS. This documentation includes [expanded examples of secure 94 deployments](https://docs.docker.com/registry/deploying/). 95 96 - **New Distribution APIs**: This release includes an expanded set of new 97 distribution APIs. You can read the [detailed specification 98 here](https://docs.docker.com/registry/spec/api/). 99 100 101 ## Docker Compose 1.2 102 103 For a complete list of compose patches, fixes, and other improvements, see the 104 [changelog in the project 105 repository](https://github.com/docker/compose/blob/master/CHANGES.md). The 106 project also makes a [set of release 107 notes](https://github.com/docker/compose/releases/tag/1.2.0) on the project. 108 109 - **extends**: You can use `extends` to share configuration between services 110 with the keyword “extends”. With extends, you can refer to a service defined 111 elsewhere and include its configuration in a locally-defined service, while also 112 adding or overriding configuration as necessary. The documentation describes 113 [how to use extends in your 114 configuration](https://docs.docker.com/compose/extends/#extending-services-in- 115 compose). 116 117 - **Relative directory handling may cause breaking change**: Compose now treats 118 directories passed to build, filenames passed to `env_file` and volume host 119 paths passed to volumes as relative to the configuration file's directory. 120 Previously, they were treated as relative to the directory where you were 121 running `docker-compose`. In the majority of cases, the location of the 122 configuration file and where you ran `docker-compose` were the same directory. 123 Now, you can use the `-f|--file` argument to specify a configuration file in 124 another directory. 125 126 127 ## Docker Swarm 0.2 128 129 You'll find the [release for download on 130 GitHub](https://github.com/docker/swarm/releases/tag/v0.2.0) and [the 131 documentation here](https://docs.docker.com/swarm/). This release includes the 132 following features: 133 134 - **Spread strategy**: A new strategy for scheduling containers on your cluster 135 which evenly spreads them over available nodes. 136 - **More Docker commands supported**: More progress has been made towards 137 supporting the complete Docker API, such as pulling and inspecting images. 138 - **Clustering drivers**: There are not any third-party drivers yet, but the 139 first steps have been made towards making a pluggable driver interface that will 140 make it possible to use Swarm with clustering systems such as Mesos. 141 142 143 ## Docker Machine 0.2 Pre-release 144 145 You'll find the [release for download on 146 GitHub](https://github.com/docker/machine/releases) and [the documentation 147 here](https://docs.docker.com/machine/). For a complete list of machine changes 148 see [the changelog in the project 149 repository](https://github.com/docker/machine/blob/master/CHANGES.md#020-2015-03 150 -22). 151 152 - **Cleaner driver interface**: It is now much easier to write drivers for providers. 153 - **More reliable and consistent provisioning**: Provisioning servers is now 154 handled centrally by Machine instead of letting each driver individually do it. 155 - **Regenerate TLS certificates**: A new command has been added to regenerate a 156 host’s TLS certificates for good security practice and for if a host’s IP 157 address changes. 158 159 ## Docker Hub Enterprise & Commercially Supported Docker Engine 160 161 See the [DHE and CS Docker Engine release notes](docker-hub-enterprise/release-notes.md).
