- When stopping containers gracefully, Compose was setting the timeout to 0, effectively forcing a SIGKILL every time.
- Compose would sometimes crash depending on the formatting of container data returned from the Docker API.

## 1.3.2

(2015-07-14)

### Bug fixes

- When there were one-off containers created by running `docker-compose run` on an older version of Compose, `docker-compose run` would fail with a name collision. Compose now shows an error if you have leftover containers of this type lying around, and tells you how to remove them.
- Compose was not reading Docker authentication config files created in the new location, `~/docker/config.json`, and authentication against private registries would therefore fail.
- When a container had a pseudo-TTY attached, its output in `docker-compose up` would be truncated.
- `docker-compose up --x-smart-recreate` would sometimes fail when an image tag was updated.
- `docker-compose up` would sometimes create two containers with the same numeric suffix.
- `docker-compose rm` and `docker-compose ps` would sometimes list services that aren't part of the current project (though no containers were erroneously removed).
- Some `docker-compose` commands would not show an error if invalid service names were passed in.

## 1.3.1

(2015-06-21)

### Bug fixes

- `docker-compose build` would always attempt to pull the base image before building.
- `docker-compose help migrate-to-labels` failed with an error.
- If no network mode was specified, Compose would set it to "bridge", rather than allowing the Docker daemon to use its configured default network mode.

## 1.3.0

(2015-06-18)

### Important notes

- **This release contains breaking changes, and you will need to either remove or migrate your existing containers before running your app** - see the [upgrading section of the install docs](https://github.com/docker/compose/blob/1.3.0rc1/docs/install.md#upgrading) for details.

- Compose now requires Docker 1.6.0 or later.

### Improvements

- Compose now uses container labels, rather than names, to keep track of containers. This makes Compose both faster and easier to integrate with your own tools.

- Compose no longer uses "intermediate containers" when recreating containers for a service. This makes `docker-compose up` less complex and more resilient to failure.

### New features

- `docker-compose up` has an **experimental** new behavior: it will only recreate containers for services whose configuration has changed in `docker-compose.yml`. This will eventually become the default, but for now you can take it for a spin:

        $ docker-compose up --x-smart-recreate

- When invoked in a subdirectory of a project, `docker-compose` will now climb up through parent directories until it finds a `docker-compose.yml`.

Several new configuration keys have been added to `docker-compose.yml`:

- `dockerfile`, like `docker build --file`, lets you specify an alternate Dockerfile to use with `build`.
- `labels`, like `docker run --labels`, lets you add custom metadata to containers.
- `extra_hosts`, like `docker run --add-host`, lets you add entries to a container's `/etc/hosts` file.
- `pid: host`, like `docker run --pid=host`, lets you reuse the same PID namespace as the host machine.
- `cpuset`, like `docker run --cpuset-cpus`, lets you specify which CPUs to allow execution in.
- `read_only`, like `docker run --read-only`, lets you mount a container's filesystem as read-only.
- `security_opt`, like `docker run --security-opt`, lets you specify [security options](/reference/cli/docker/container/run/#security-opt).
- `log_driver`, like `docker run --log-driver`, lets you specify a [log driver](/reference/cli/docker/container/run/#log-driver).

### Bug fixes

- The output of `docker-compose run` was sometimes truncated, especially when running under Jenkins.
- A service's volumes would sometimes not update after volume configuration was changed in `docker-compose.yml`.
