no longer converted from `C:\Users` to `/c/Users`-style by default. To
  re-enable this conversion so that your volumes keep working, set the
  environment variable `COMPOSE_CONVERT_WINDOWS_PATHS=1`. Users of
  Docker for Windows are not affected and do not need to set the variable.

### New Features

- Interactive mode for `docker-compose run` and `docker-compose exec` is
  now supported on Windows platforms. The `docker` binary
  is required to be present on the system for this feature to work.

- Introduced version 2.1 of the `docker-compose.yml` specification. This
  version requires to be used with Docker Engine 1.12 or above.
    - Added support for setting volume labels and network labels in
  `docker-compose.yml`.
    - Added support for the `isolation` parameter in service definitions.
    - Added support for link-local IPs in the service networks definitions.
    - Added support for shell-style inline defaults in variable interpolation.
      The supported forms are `${FOO-default}` (fall back if FOO is unset) and
      `${FOO:-default}` (fall back if FOO is unset or empty).

- Added support for the `group_add` and `oom_score_adj` parameters in
  service definitions.

- Added support for the `internal` and `enable_ipv6` parameters in network
  definitions.

- Compose now defaults to using the `npipe` protocol on Windows.

- Overriding a `logging` configuration will now properly merge the `options`
  mappings if the `driver` values do not conflict.

### Bug fixes

- Fixed several bugs related to `npipe` protocol support on Windows.

- Fixed an issue with Windows paths being incorrectly converted when
  using Docker on Windows Server.

- Fixed a bug where an empty `restart` value would sometimes result in an
  exception being raised.

- Fixed an issue where service logs containing unicode characters would
  sometimes cause an error to occur.

- Fixed a bug where unicode values in environment variables would sometimes
  raise a unicode exception when retrieved.

- Fixed an issue where Compose would incorrectly detect a configuration
  mismatch for overlay networks.

## 1.8.1

(2016-09-22)

### Bug fixes

- Fixed a bug where users using a credentials store were not able
  to access their private images.

- Fixed a bug where users using identity tokens to authenticate
  were not able to access their private images.

- Fixed a bug where an `HttpHeaders` entry in the docker configuration
  file would cause Compose to crash when trying to build an image.

- Fixed a few bugs related to the handling of Windows paths in volume
  binding declarations.

- Fixed a bug where Compose would sometimes crash while trying to
  read a streaming response from the engine.

- Fixed an issue where Compose would crash when encountering an API error
  while streaming container logs.

- Fixed an issue where Compose would erroneously try to output logs from
  drivers not handled by the Engine's API.

- Fixed a bug where options from the `docker-machine config` command would
  not be properly interpreted by Compose.

- Fixed a bug where the connection to the Docker Engine would
  sometimes fail when running a large number of services simultaneously.

- Fixed an issue where Compose would sometimes print a misleading
  suggestion message when running the `bundle` command.

- Fixed a bug where connection errors would not be handled properly by
  Compose during the project initialization phase.

- Fixed a bug where a misleading error would appear when encountering
  a connection timeout.

## 1.8.0

(2016-06-14)

### Breaking Changes

- As announced in 1.7.0, `docker-compose rm` now removes containers
  created by `docker-compose run` by default.

- Setting `entrypoint` on a service now empties out any default
  command that was set on the image (i.e. any `CMD` instruction in the
  Dockerfile used to build it). This makes it consistent with
  the `--entrypoint` flag to `docker run`.

### New Features

- Added `docker-compose bundle`, a command that builds a bundle file
