Many apologies if folks may be a little confused. This is a
new versioning system for our enterprise product. We've done this in an effort to be more explicit about product versioning, which should also result in fewer namespace (version space) collisions with individual upstream projects.
This is a major release as Puppet Enterprise 2015.2 marks a new series. It has a new Puppet, new Puppet Server, totally new UI, and the all-in-one unified agent. For more information on the versioning please check out the
blog post we released earlier today.
Finally, thank you for catching the 3.8 reference at the bottom of the page. We've got that updated.
