This release comes with a simplified Wiki Creation Wizard and the ability to organize and filter extensions by category in the Extension Repository. The install date and the user that performed the install are now available in the extension details, and the extensions that were installed explicitly are now displayed distinctly. A stronger confirmation should prevent users from deleting wikis by mistake from now on. The developers may be interested by the API improvements made to the Mail Sender and Extension Manager modules.
