## 0.7.3 (2014-01-02)
### Builder
+ Update ADD to use the image cache, based on a hash of the added content
* Add error message for empty Dockerfile
### Documentation
- Fix outdated link to the "Introduction" on www.docker.io
+ Update the docs to get wider when the screen does
- Add information about needing to install LXC when using raw binaries
* Update Fedora documentation to disentangle the docker and docker.io conflict
* Add a note about using the new `-mtu` flag in several GCE zones
+ Add FrugalWare installation instructions
+ Add a more complete example of `docker run`
- Fix API documentation for creating and starting Privileged containers
- Add missing "name" parameter documentation on "/containers/create"
* Add a mention of `lxc-checkconfig` as a way to check for some of the necessary kernel configuration
- Update the 1.8 API documentation with some additions that were added to the docs for 1.7
### Hack
- Add missing libdevmapper dependency to the packagers documentation
* Update minimum Go requirement to a hard line at Go 1.2+
* Many minor improvements to the Vagrantfile
+ Add ability to customize dockerinit search locations when compiling (to be used very sparingly only by packagers of platforms who require a nonstandard location)
+ Add coverprofile generation reporting
- Add `-a` to our Go build flags, removing the need for recompiling the stdlib manually
* Update Dockerfile to be more canonical and have less spurious warnings during build
- Fix some miscellaneous `docker pull` progress bar display issues
* Migrate more miscellaneous packages under the "pkg" folder
* Update TextMate highlighting to automatically be enabled for files named "Dockerfile"
* Reorganize syntax highlighting files under a common "contrib/syntax" directory
* Update install.sh script (https://get.docker.io/) to not fail if busybox fails to download or run at the end of the Ubuntu/Debian installation
* Add support for container names in bash completion
### Packaging
+ Add an official Docker client binary for Darwin (Mac OS X)
* Remove empty "Vendor" string and added "License" on deb package
+ Add a stubbed version of "/etc/default/docker" in the deb package
### Runtime
* Update layer application to extract tars in place, avoiding file churn while handling whiteouts
- Fix permissiveness of mtime comparisons in tar handling (since GNU tar and Go tar do not yet support sub-second mtime precision)
* Reimplement `docker top` in pure Go to work more consistently, and even inside Docker-in-Docker (thus removing the shell injection vulnerability present in some versions of `lxc-ps`)
+ Update `-H unix://` to work similarly to `-H tcp://` by inserting the default values for missing portions
- Fix more edge cases regarding dockerinit and deleted or replaced docker or dockerinit files
* Update container name validation to include '.'
- Fix use of a symlink or non-absolute path as the argument to `-g` to work as expected
* Update to handle external mounts outside of LXC, fixing many small mounting quirks and making future execution backends and other features simpler
