* Adds `cpu_set` to docker container [[#41](https://github.com/terraform-providers/terraform-provider-docker/pull/41)]
* Simplifies the image options parser and adds missing registry combinations [[#49](https://github.com/terraform-providers/terraform-provider-docker/pull/49)]
* Adds container static IPv4/IPv6 address. Marks network and network_alias as deprecated. [[#105](https://github.com/terraform-providers/terraform-provider-docker/pull/105)]
* Adds container logs option [[#108](https://github.com/terraform-providers/terraform-provider-docker/pull/108)]
BUG FIXES
