Version 184.108.40.206 Notes: Update for Chrome 71.0.3578.98.
Version 220.127.116.11 Notes: Mandatory update to Chrome Extension Manifest version 2.
Version 18.104.22.168 Notes: Chrome 17 has been updated such that the print preview window is no longer presented in a new tab. Now the print preview window opens up in a child window in the current tab. This broke the 'open in New Window' feature.
To compensate for this, the Awesome Print Button version 22.214.171.124 'open in New Window' option now duplicates the selected tab in a new window, and then triggers the Chrome print preview window.
