You will be able to use information from Wikidata directly in Wikiquote pages starting on June 10. 
On wikis with the Translate extension enabled, translation administrators will soon be able to use the page migration tool to import existing translations to the new system. 
You will soon see metadata on file description pages for Ogg files (example video, example audio). Some files with non-English metadata may need to have their description page purged before they show correctly. 
Templates containing <ref> or <references> tags will no longer need dummy parameters to prevent caching. 
You will no longer be able to use Special:Thanks directly. The page will soon show an error message when you visit it.
