PuppetDB 4.0.0 Release Notes
----------------------------

Users should consult the release notes here: https://docs.puppetlabs.com/puppetdb/4.0/release_notes.html

Some changes we’re excited about are:

 - PQL - a new query language that is simpler and easier for users to run queries against PuppetDB
 - Queries now support an ‘in’ clause to match against a list of items, this is supported in the original ‘AST’ query language along with PQL
 - A new endpoint where all entities can be queried; users no longer need to use a ‘resources’ or ‘reports’ endpoint, though those endpoints remain available
 - The terminus now supports command broadcasting, to allow submitting commands to multiple PuppetDB backends
