Say Hello to Open Source Puppet 4!

[SIbinPhilip]

Production-ready Open Source Puppet 4 is now available! We’re excited to announce new features and enhancements that will extend your use of Puppet for faster, more consistent management of server configurations. We’ve added capabilities to help you save time, reduce errors, and increase reliability.

Gain More Power and Reduce Errors with a Modernized Puppet Language
During the past year, we’ve had new language changes available to the community for preview and testing. Thanks to your valuable feedback, we’ve completely rewritten the parser and evaluator, ironed out some kinks, and learned how these changes interacted with all of the Puppet manifests already out in the wild. In short, the future parser is no longer in the realm of the future. It’s here, and available by default. Also, the enhanced Puppet language delivers more power and greater reliability with smarter, more compact, code that is more human readable than ever before.

Save Time and Resources Installing and Updating Open Source Puppet
We recognize that installing and updating software can be tedious and frustrating, often involving manually moving files, potential duplication and time spent sorting out disparate deployment methods. Our goal was to provide a great installation experience regardless of the platform you are running. With Puppet 4, you get a simple, streamlined experience with an all-in-one (AIO) package that includes Puppet 4, both Facter 2.4 and CFacter 0.4, the latest Hiera and MCollective, Ruby 2.1.5, OpenSSL 1.0.0r and our gem dependencies.

Along with Puppet 4, we are introducing Puppet Collections, a new way of delivering our open source software to you. A Puppet Collection is a package repository that ensures our open source packages in a particular collection work together. Just think of it like a Linux distribution, but for Puppet-related packages. Be sure to review the Puppet Collections blog post() to learn how these improvements will help you.
