Announcement: Release of Puppet Platform 6.0

[Michelle Fredette]

Hello Everyone!

We're happy to announce the release of Puppet Platform 6.0. This is a major Puppet release including many new features, improvements, bug fixes, and some deprecations. 

Some highlights

- Modularized types to enable easier composability and reusability of the Puppet codebase and enable development to proceed more quickly without fear of destabilizing the rest of Puppet.

- Resource API provides a new, recommended method to create custom types and providers. The Resource API is built on top of Puppet core and is easier, faster, and safer than the old types and providers method.

- All CA actions now reside entirely in Puppet Server using the CA API and the `puppetserver ca` command, which leverages the API using subcommands like those previously provided by `puppet cert`. 

And much more! See Puppet, Puppet agent, Puppet Server, and PuppetDB release notes for more information.
