The Duke WordPress system was successfully upgraded to version 4.0 this morning (Saturday, October 11).
Please note that we removed 3 unused or unsupported plugins from the system. In cases where retired plugins were actively used by Duke WordPress users, we suggested alternative plugins with similar functions: http://sites.duke.edu/blog/2014/09/18/plugins-to-be-removed-during-october-2014-maintenance-window/.

Any feature suggestions received by November 15, 2014, will be considered for our next maintenance window in December/January 2014.
