The Roy Rosenzweig Center for History and New Media has released Omeka 2.1.4.
Here's an excerpt from the announcement:
This maintenance release includes some style additions and corrections in the admin theme, as well as a fix to how records are sorted for newer versions of MySQL. . .
Updated versions of the COinS and Exhibit Builder plugins are also bundled with this release, fixing an error in COinS for PHP 5.2. The updated Exhibit Builder plugin improves many parts of the styling, especially across interaction with many plugins, and expands the data returned by the API.
