Maestro-ng

---------------

_May 30th, 2014_

* Fixed link variable naming for port names containing dashes

-------------

_May 28th, 2014_

* Support for custom image command
* Implement restart Maestro command
* Add support for "soft" dependencies through `wants_info`. Containers
get the link environment variable, but the dependency has no impact on
the start/stop orders
* Improve guestutils service matching by including a list of each
service's instances as a `<service_name>_INSTANCES` environment
variable

---------------

_April 28th, 2014_

* Support for memory and cpu shares limits
* Fix image:tag parsing when custom registries are involved
* Improve Jinja2 setup to include filesystem loader and with extension
for more flexible and complex Jinja2 templating capabalities

-------------

_April 9th, 2014_

* Use `docker-py` 0.3.x
* Deep expend of environment variables list values
* Pre-processing of the YAML environment description through Jinja2
templating
* Correctly pass-in specified volumes to create_container() in case the
image's Dockerfile didn't define them
* Support service-level environment variables that trickle down to all
instances of the service
* Documentation improvements, flake8 and unit-test fixes
* Support for privileged containers
* Support for timeout on container stop

-------------

_January 30th, 2014_

* Fullstatus output now shows port numbers
* Improved port specification syntax for more precise control about
internal and exposed ports and interfaces
* Maestro extension for logstash-based logging scaffolding
* Docker and `docker-py` compatibility fixes (Id/ID, `docker-py` API
tweaks)
* Show image being pulled when creating a container

-------------

_January 16th, 2014_

* Fix download indicator for compatibility with Docker 0.7.x
* Renamed 'status' command to 'fullstatus', and implemented new, faster
'status' command that only looks at the state of the containers, not
the services themselves
* Sort containers before building dependencies to try to keep them a bit
more organized without breaking the dependency order
* Don't use white in commands output, just bold text
* Compatibility fixes with docker-py 0.2.3
* The 'logs' command now streams logs instead of dumping them, until you
hit ^C to stop
* Implement registry login before pull, when needed and if possible
* Renamed 'scores' to 'plays', makes more sense
* Updates to the 'logs' command:
- by default, the 'logs' command now dumps the full log and doesn't
stream/follow
- with the '-F' flag, logs will be followed
- the new '-n N' flag will only show the last N lines of the log, but
it doesn't work with streaming logs
* Setup for Travis-CI build with flake8 validation
