Hello and welcome to the new API list.
The new version of the API is now up on all WikiMedia sites, e.g. http://en.wikipedia.org/w/api.php
== Breaking Changes == backlinks, embeddedin, and imageusage lists no longer use the global "titles=" parameter; instead backlinks now uses bltitle=, embeddedin -- eititle=, and imageusage -- "iutitle=". For a little while, if you do not supply ...title= parameter, titles= will still work, but a warning is returned. Soon it will not work, so please update your code if you use any of this 3 lists.
== New Features == * list=categorymembers - list pages/categories belonging to a category * page protection status * prop=imageinfo - returns image info including repository, size, URLs, and upload history * list=exturlusage - search for URLs used in a wiki * list=alllinks - list all links, regardless of what page they are on (allows search for unique links only ) * list=allusers - list of all users registered in a wiki, together with an edit count * prop=siteinfo - can now return database servers replication lag
== Other Changes == * Documentation has been significantly updated with examples. Please contribute more :) : http://www.mediawiki.org/wiki/API * Report bugs & post requests are at http://bugzilla.wikimedia.org/buglist.cgi?component=API&bug_status=NEW&a... (don't forget to set Component=API when creating new entries)
== Current Issues == * Security: If a namespace cannot be read by the current user, some of the titles in that NS are still shown in various enumerations (e.g. in the apfrom= continue value)
== Current Efforts == * Some core code has been updated to allow Rollback implementation (thanks Roan). * API home page needs short coding examples of client access for Python, PHP, C#, and Java clients (or any other languages if you prefer).
