The big-six-o. This release is largely comprised of new features that should allow for easier management of dokku. The highlights of this release are:

• The proxy plugin has been enhanced to allow users to map container ports to host ports. In the 0.5.0 release, we changed the semantics of how Dockerfile EXPOSE calls work to better follow Docker's lead, which ended up breaking how some applications were deployed to dokku. Please read our documentation surrounding port management for more details.
• Zero-downtime deploys can be disabled on a per-app and per-process basis. This can be used to speed up deploys when there are non-web processes being deployed, or when a user wishes to completely avoid any such waiting period. Please see the checks documentation for further information.

If, after upgrading, you are seeing issues where the dokku binary isn't found - /usr/local/bin/dokku: No such file or directory - please log out and log back in.

Thanks to all the contributors who helped with this release, and a special thanks to @michaelshobbs for ferrying the majority of our new functionality to it's current state!
