If a release branch has already been cut Rebuild the pacakge promotion job with the release branch set instead of master or 2018.1.x.
Once it's promoted to the release branch checkout the release branch of enterprise-dist locally and verify that all platforms have the same tagged version of pe-puppetdb
bundle exec rake report:packages
If there were any important dependency bumps, such as to fix a bug or CVE, verify that they were updated by navigating to the release and then to the pe-puppetdb package on [pebuildinfo|pebuildinfo.slice.puppetlabs.net/].
Once builds are promoted push SNAPSHOT versions to both pdb and pdbext github repos targeting the next release.
Remember to revert pe-puppetdb-extensions to reading the version from the file
