For more information see the 20 [IPv6 networking reference](/articles/networking/#ipv6). 21 * Docker container filesystems can now be set to`--read-only`, restricting your 22 container to writing to volumes [PR# 10093](https://github.com/docker/docker/pull/10093). 23 * A new `docker stats CONTAINERID` command has been added to allow users to view a 24 continuously updating stream of container resource usage statistics. See the 25 [`stats` command line reference](/reference/commandline/cli/#stats) and the 26 [container `stats` API reference](/reference/api/docker_remote_api_v1.17/#get-container-stats-based-on-resource-usage). 27 **Note**: this feature is only enabled for the `libcontainer` exec-driver at this point. 28 * Users can now specify the file to use as the `Dockerfile` by running 29 `docker build -f alternate.dockerfile .`. This will allow the definition of multiple 30 `Dockerfile`s for a single project. See the [`docker build` command reference]( 31 /reference/commandline/cli/#build) for more information. 32 * The v1 Open Image specification has been created to document the current Docker image 33 format and metadata. Please see [the Open Image specification document]( 34 https://github.com/docker/docker/blob/master/image/spec/v1.md) for more details. 35 * This release also includes a number of significant performance improvements in 36 build and image management ([PR #9720](https://github.com/docker/docker/pull/9720), 37 [PR #8827](https://github.com/docker/docker/pull/8827)) 38 * The `docker inspect` command now lists ExecIDs generated for each `docker exec` process. 39 See [PR #9800](https://github.com/docker/docker/pull/9800)) for more details. 40 * The `docker inspect` command now shows the number of container restarts when there 41 is a restart policy ([PR #9621](https://github.com/docker/docker/pull/9621)) 42 * This version of Docker is built using Go 1.4 43 44 > **Note:** 45 > Development history prior to version 1.0 can be found by 46 > searching in the [Docker GitHub repo](https://github.com/docker/docker). 47 48 ## Known Issues 49 50 This section lists significant known issues present in Docker as of release 51 date. It is not exhaustive; it lists only issues with potentially significant 52 impact on users. This list will be updated as issues are resolved. 53 54 * **Unexpected File Permissions in Containers** 55 An idiosyncrasy in AUFS prevents permissions from propagating predictably 56 between upper and lower layers. This can cause issues with accessing private 57 keys, database instances, etc. For complete information and workarounds see 58 [Github Issue 783](https://github.com/docker/docker/issues/783). 59 60 * **Docker Hub incompatible with Safari 8** 61 Docker Hub has multiple issues displaying on Safari 8, the default browser 62 for OS X 10.10 (Yosemite). Users should access the hub using a different 63 browser. Most notably, changes in the way Safari handles cookies means that the 64 user is repeatedly logged out. For more information, see the [Docker 65 forum post](https://forums.docker.com/t/new-safari-in-yosemite-issue/300).
