v2.3

• Omeka Classic themes had previously used Compass to manage its Sass and CSS. Compass is now at end-of-life, so themes now use a gulp to automate the Sass workflow. Users can read more about using the new workflow here: http://omeka.org/s/docs/developer/key_concepts/working_with_Sass_and_CSS/.

• Adjust for new markup in collection items.
