"The feature set isn't the big news, though – the move to the GPLv3 is. The project has been open source for some time, but not entirely. The company had kept two codebases – one for the community, one for paying customers. This means that the open source community now has (or will have) all the same features as customers like GoDaddy. Previously, the company held back connectors for proprietary software, such as VMware's hypervisor and connectors to NetApp storage and F5 load balancers. A preview release is out now, though it's not considered production ready just yet."
