# Changelog
## 1.6.0 (2015-04-07)

+ Building images from an image ID
+ build containers with resource constraints, ie `docker build --cpu-shares=100 --memory=1024m...`
+ `commit --change` to apply specified Dockerfile instructions while committing the image
+ `import --change` to apply specified Dockerfile instructions while importing the image
#### Client
+ Windows Support
#### Runtime
+ Container and image Labels
+ `--cgroup-parent` for specifying a parent cgroup to place container cgroup within
+ Logging drivers, `json-file`, `syslog`, or `none`
+ Pulling images by ID
+ `--ulimit` to set the ulimit on a container
+ `--default-ulimit` option on the daemon which applies to all created containers (and overwritten by `--ulimit` on run)
