  Bjarne for help with testing.

4.1.1 & 4.1.2 & 4.1.3 & 4.1.4

• Bug Fix: Resolves various errors reported following 4.1 release.

4.1

• Enhancement: At long last, support for Microsoft Office files (Word, PowerPoint, Publisher, Visio), as well as a
  boat-load of other formats, has been re-added to Document Gallery by way of
  integration with the Thumber.co service. For a small fee you can generate images for all of your
  attachments using a service designed specifically to work well with Document Gallery. For a limited time,
  Thumber.co is offering a free 7-day trial of the basic subscription. If you don’t like it, all you have to do is
  cancel and you won’t pay a penny.
• Enhancement: The pagination footer now includes more than just “prev” and “next”, allowing for quicker navigation
  of long multi-page galleries. Additionally, the pagination footer will no longer be included if pagination is enabled,
  but there are less than a page-length’s worth of attachments in the gallery.
• Enhancement: Massive rewrite of some core logic that had become unmaintainable. This will mean nothing to most
  users, with the noted exception that if you were using the dg_thumbers filter you’ll need to change some things.
  If this applies to you then you’ll want to hold off on upgrading until you’ve had a chance to rework your usage of the
  filter to map to the new expected values.

4.0

• Enhancement: The WordPress visual editor now displays a full gallery preview.
• Enhancement: You can now paginate your galleries. This is especially useful in large multi-hundred item galleries.
  To enable pagination in your galleries, simply use limit=##.
• Enhancement: All CSS & JavaScript is now served minified to ensure the fastest possible load time for your site.
• Enhancement: When using taxonomies to generate your galleries (eg: media categories) you can now use term slug
  instead of the name. Thanks andremalenfant for suggesting this!
• Enhancement: The structure of the gallery output has been cleaned up, making it easier to style if you chose to
  use custom CSS. NOTE: This modified structure may break existing custom CSS or PHP filtering, so be sure to check
  this if you’re using either of those features.
• Bug Fix: The storage of the DG thumbnail cache was very broken. Due to how the cache was originally designed, it
  ran into issues at large scale and on busy sites, which resulted in difficult to track bugs. The entire storage
  mechanism for the cache has been rewritten from the ground up to address this issue, which will result in faster
  gallery generation and more reliable performance.
• Bug Fix: In the thumbnail management tab of the DG settings, sorting by title was broken. This has been fixed.
• Bug Fix: Limit was not working in cases where the ids or include attribute were present. This has been fixed.
• Tested Up To: Document Gallery has been tested in WP 4.4 beta.

NOTE: All earlier changes may be found in the CHANGELOG.md file.
