== *Changes* == * list=watchlist now returns user id in properly named tag in addition to "user". In the case of wlprop=user|userid, the "user" will be the name, not the id as before.(patch https://gerrit.wikimedia.org/r/#/c/49390/ by Petr Onderka) * meta=allmessages&lang= will now return "aminvalidlang" error in case "lang" contains invalid characters (patchhttps://gerrit.wikimedia.org/r/#/c/53362/ by Anomie)

== *New functionality* == * There is now a newhttp://www.mediawiki.org/wiki/API:Query#Continuing_queries, simplified way to iterate through the query results. The new feature will make it much less likely to accidentally skip any data, and will greatly simplify client code. It will be made default in API 2.0http://www.mediawiki.org/wiki/Requests_for_comment/API_Future, but for now has to be explicitly enabled with a "*continue=*" parameter. See sample code http://www.mediawiki.org/wiki/API:Query#Continuing_queries how to use the new continue. Please consider using it in all new development.
