Document Gallery - Version 4.3.1

Version Description

  • Enhancement: WordPress 4.7 includes native support for PDF thumbnails. Document Gallery was already using some of this, but this update ensures that DG takes full advantage of the new core functionality, including some new logic to allow older WordPress installs running Document Gallery to take advantage of some of the new goodies.
  • Tested Up To: Document Gallery has been tested in WP 4.7. Big thanks to Bjarne for help with testing.
  • Reminder: Don't forget that Thumber.co can integrate with Document Gallery to greatly expand supported file types (eg: Word, PowerPoint, Publisher, and Photoshop). Thumber.co offers a free 1-week trial if you want to try it before you buy it!
