Ports using USE_PYTHON=distutils are now flavored. They will
automatically get flavors (py27, py34, py35, py36) depending on what
versions they support.
There is also a USE_PYTHON=flavors for ports that do not use distutils
but need FLAVORS to be set. A USE_PYTHON=noflavors can be set if
using distutils but flavors are not wanted.
A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
added to cope with Python ports that did not have the Python
PKGNAMEPREFIX but are flavored.
USES=python now also exports a PY_FLAVOR variable that contains the
current python flavor. It can be used in dependency lines when the
port itself is not python flavored. For example, deskutils/calibre.
By default, all the flavors are generated. To only generate flavors
for the versions in PYTHON2_DEFAULT and PYTHON3_DEFAULT, define
BUILD_DEFAULT_PYTHON_FLAVORS in your make.conf.
In all the ports with Python dependencies, the *_DEPENDS entries MUST
end with the flavor so that the framework knows which to build/use.
This is done by appending '@${PY_FLAVOR}' after the origin (or
@${FLAVOR} if in a Python module with Python flavors, as the content
will be the same). For example:
RUN_DEPENDS= ${PYTHON_PKGNAMEPREFIX}six>0:devel/py-six@${PY_FLAVOR}

### Breaking changes
- `docker-compose up` now resets a service's scaling to its default value.
You can use the newly introduced `--scale` option to specify a custom
scale value
### New features
#### Compose file version 2.2
- Introduced version 2.2 of the `docker-compose.yml` specification. This
version requires to be used with Docker Engine 1.13.0 or above
- Added support for `init` in service definitions.
- Added support for `scale` in service definitions. The configuration's value
can be overridden using the `--scale` flag in `docker-compose up`.
Please note that the `scale` command is disabled for this file format
#### Compose file version 2.x
- Added support for `options` in the `ipam` section of network definitions
Compose is a tool for defining and running multi-container Docker applications.
With Compose, you use a Compose file to configure your application's services.
Then, using a single command, you create and start all the services from your
configuration.
