PE 2015.2.2: puppetdb version num?

Hey Guys, according to this https://docs.puppetlabs.com/puppetdb/latest/#puppet-400 PuppetDB 3.1 » Overview This version of PuppetDB is not currently included in a Puppet Enterprise release. PE 2015.2 users should see the PuppetDB 3.0 docs. but I've got PE 2015.2.2 and according to rpm (Centos 6.7), I've got pe-puppetdb-3.1.1-1.el6.noarch. Can any PuppetLabs guy confirm if the doc is wrong? Thx
Chris
