    11  (2015-02-03)

    14  [merge PR on GitHub](https://github.com/docker/docker/pull/10286).
    15  
    16  *New Features*
    17  
    18  * [1.6] The Docker daemon will no longer ignore unknown commands
    19    while processing a `Dockerfile`. Instead it will generate an error and halt
    20    processing.
    21  * The Docker daemon has now supports for IPv6 networking between containers
    22    and on the `docker0` bridge. For more information see the
    23    [IPv6 networking reference](/articles/networking/#ipv6).
    24  * Docker container filesystems can now be set to`--read-only`, restricting your
    25    container to writing to volumes [PR# 10093](https://github.com/docker/docker/pull/10093).
    26  * A new `docker stats CONTAINERID` command has been added to allow users to view a
    27    continuously updating stream of container resource usage statistics. See the
    28    [`stats` command line reference](/reference/commandline/cli/#stats) and the
    29    [container `stats` API reference](/reference/api/docker_remote_api_v1.17/#get-container-stats-based-on-resource-usage).
    30    **Note**: this feature is only enabled for the `libcontainer` exec-driver at this point.
    31  * Users can now specify the file to use as the `Dockerfile` by running
    32    `docker build -f alternate.dockerfile .`. This will allow the definition of multiple
    33    `Dockerfile`s for a single project. See the [`docker build` command reference](
    34  /reference/commandline/cli/#build) for more information.
    35  * The v1 Open Image specification has been created to document the current Docker image
    36    format and metadata. Please see [the Open Image specification document](
    37  https://github.com/docker/docker/blob/master/image/spec/v1.md) for more details.
    38  * This release also includes a number of significant performance improvements in
    39    build and image management ([PR #9720](https://github.com/docker/docker/pull/9720),
    40    [PR #8827](https://github.com/docker/docker/pull/8827))
    41  * The `docker inspect` command now lists ExecIDs generated for each `docker exec` process.
    42    See [PR #9800](https://github.com/docker/docker/pull/9800)) for more details.
    43  * The `docker inspect` command now shows the number of container restarts when there
    44    is a restart policy ([PR #9621](https://github.com/docker/docker/pull/9621))
    45  * This version of Docker is built using Go 1.4

    51  ## Known Issues
    52  
    53  This section lists significant known issues present in Docker as of release
    54  date. It is not exhaustive; it lists only issues with potentially significant
    55  impact on users. This list will be updated as issues are resolved.
    56  
    57  * **Unexpected File Permissions in Containers**
    58  An idiosyncrasy in AUFS prevents permissions from propagating predictably
    59  between upper and lower layers. This can cause issues with accessing private
    60  keys, database instances, etc.
    61  
    62  For systems that have recent aufs version (i.e., `dirperm1` mount option can
    63  be set), docker will attempt to fix the issue automatically by mounting
    64  the layers with `dirperm1` option. More details on `dirperm1` option can be
    65  found at [`aufs` man page](http://aufs.sourceforge.net/aufs3/man.html)
    66  
    67  For complete information and workarounds see
    68  [Github Issue 783](https://github.com/docker/docker/issues/783).
    69  
    70  * **Docker Hub incompatible with Safari 8**
    71  Docker Hub has multiple issues displaying on Safari 8, the default browser
    72  for OS X 10.10 (Yosemite). Users should access the hub using a different
    73  browser. Most notably, changes in the way Safari handles cookies means that the
    74  user is repeatedly logged out. For more information, see the [Docker
    75  forum post](https://forums.docker.com/t/new-safari-in-yosemite-issue/300).
