As of today, interactive (Kartographer) maps no longer display in the language of the territory mapped; instead, you’ll read them in the content language of the wiki where they appear—or in the language their authors specify (subject to availability of multilingual data). In addition, mapframe, the feature that automatically embeds dynamic maps right on a wiki page, is now live on most Wikipedias that lacked the feature. (Not included in the mapframe launch are nine Wikipedias  that use the stricter version of Flagged Revisions).
If you you’re new to mapframe, this Kartographer help page  shows how to get started putting dynamic maps on your pages. If you’d like to read more about map internationalization: this Special Update  explains the feature and its limiations; this post  and this one  describe the uses of the new parameter, lang=”xx”, which lets you specify a map’s language. And here are some example maps  to illustrate the new capabilities.
These features could not have been created without the generous programming contributions and advice of our many map-loving volunteers, including Yurik, Framawiki, Naveenpf, TheDJ, Milu92, Astirlin, Evad37, Pigsonthewing, Mike Peel, Eran Roz, Gareth and Abbe98. My apologies to anyone I’ve missed.
The Map Improvements 2018  project wraps up at the end of June, so please give internationalized maps and mapframe a try soon and give us your feedback on the project talk page . We’re listening.
