Facter 4 release

[Bogdan Irimie]

Hi,

I am very happy to announce the first release of Facter 4. The team has worked tirelessly these last couple of weeks to make the transition for projects that use Facter as a gem (for example Modules CI pipelines) as smooth as possible. 

If you experience any issues with Facter 4 or you are not ready to migrate to it, you can revert back to Facter 2 by setting Facter version in your gemfile. If you are using rspec_puppet for tests, you can use FACTER_GEM_VERSION to set the Facter version.

One of the objectives for Facter 4 is to be compatible with Facter 3, so expect frequent releases that will close the gap between Facter 3 and Facter 4. 

The entire team is really excited about this release and we are looking forward to your feedback. Feel free to reach out on slack or open a ticket on https://tickets.puppetlabs.com/projects/FACT with facter-ng label.

Best regards,

Bogdan Irimie
