[announce] beaker 2.18.2 released

[Kevin Imber]

Included in this release:

- BKR-405 - `install_pe` fails to install  SG if `Latest-Win` version file is missing

    Note that the URL slash issue that many are facing has been taking care of as a part of this one.

- BKR-420 - Allow easily installing latest puppet-agent

    Prior to this we were over eagerly failing if there was no puppet-agent version explicitly set.  Having install_puppet_agent install the latest released version of puppet-agent is a desired and common workflow.

High Fives!
