I came here to let people know there will be a Puppet v5-specific update to the Learning Puppet book coming out soon. Then I realized I’d forgotten to post the last update. Oops! Well, there have been and will be quite a few updates…
TL;DR The Learning Puppet book from O’Reilly receives continuous updates.
Back in February we pushed updates to bring the book current to Puppet 4.10. Since then I was tied up with getting Puppet Best Practices out the door.
Next up will be Puppet v5 complete update to Learning Puppet.
