### New features

### Bug fixes

- Volumes specified through the `--volume` flag of `docker-compose run` now
  complement volumes declared in the service's definition instead of replacing
  them

- Fixed a bug where using multiple Compose files would unset the scale value
  defined inside the Compose file.

- Fixed an issue where the `credHelpers` entries in the `config.json` file
  were not being honored by Compose

- Fixed a bug where using multiple Compose files with port declarations
  would cause failures in Python 3 environments

- Fixed a bug where some proxy-related options present in the user's
  environment would prevent Compose from running

- Fixed an issue where the output of `docker-compose config` would be invalid
  if the original file used `Y` or `N` values

- Fixed an issue preventing `up` operations on a previously created stack on
  Windows Engine.

  `cpu_percent`, `cpus`

#### Compose file version 2.1

- Added support for build labels. This feature is also available in the
  2.2 and 3.3 formats.

#### All formats

- Added shorthand `-u` for `--user` flag in `docker-compose exec`

- Differences in labels between the Compose file and remote network
  will now print a warning instead of preventing redeployment.

### Bug fixes

- Fixed a bug where service's dependencies were being rescaled to their
  default scale when running a `docker-compose run` command

- Fixed a bug where `docker-compose rm` with the `--stop` flag was not
  behaving properly when provided with a list of services to remove

- Fixed a bug where `cache_from` in the build section would be ignored when
  using more than one Compose file.

- Fixed a bug that prevented binding the same port to different IPs when
  using more than one Compose file.

- Fixed a bug where override files would not be picked up by Compose if they
  had the `.yaml` extension

- Fixed a bug on Windows Engine where networks would be incorrectly flagged
  for recreation

- Fixed a bug where services declaring ports would cause crashes on some
  versions of Python 3

- Fixed a bug where the output of `docker-compose config` would sometimes
  contain invalid port definitions

## 1.13.0

### Breaking changes
