Hi all!

We have some breaking API changes that will soon be deployed to wikidata.org.

The deployment date should be: 9th September 2015 (just under 2 weeks)

The change making the breaks an be found at:

https://gerrit.wikimedia.org/r/#/c/227686/

The breaking changes are:
 - XML output aliases are now grouped by language
 - XML output may no longer give elements when they are empty
 - XML any claim, qualifier, reference or snak elements that had an '_idx' element will no longer have it
 - ALL output may now give empty elements, ie. labels when an entity has none

If you want to see a wikipage explaining these changes take a look at:
